In today's episode of Welcome to Cloudlandia, we reflect on serenity in nature and technology, drawing parallels between Cloudlandia and meticulously raked sand. Woven into our talk is AI and how it's changing everything, from Evan's course helping us out at work to all the crazy experiments shaking things up. We get into how innovation unexpectedly boosted my creativity, which we're calling "exponential tinkering". As our annual event nears, lessons in "exponential thinking" add to the anticipation of a reunited community and potential for growth. SHOW HIGHLIGHTS Dean and I explore the serenity of Cloudlandia and how it parallels the peacefulness found in Japanese Zen gardens, reflecting on the role of imagination in experiencing digital spaces. We discuss the success of Evan Ryan's AI course within our company and how it has encouraged experiments with AI across different teams. Dean introduces the concept of "exponential tinkering," highlighting how AI is revolutionizing the arts and content creation, with a nod to OpenAI's Sora tool. We contemplate the cultural shift toward immersive experiences like VR, while expressing skepticism about their long-term utility and appeal. Dan recognizes the importance of integrating existing consumer experiences to create innovative products, using Apple as an example. We highlight insights from Mark Mills' book "The Cloud Revolution" on the strategic importance of reshoring supply chains and repurposing shopping centers into logistics hubs. We compare Tesla's success to the sustainability challenges faced by other electric vehicle companies that are more dependent on government subsidies. We share anecdotes about the Soviet-era's illusion of luxury, and how modern-day explorers uncover the true state of Soviet infrastructure. We examine the declining enthusiasm for venture capital in the tech world and the concept of "cruel optimism" that can be prevalent in this sector. Excitement is expressed for our upcoming annual event, stressing the value of 'exponential thinking' and the potential growth of our community.

Dan: Well, welcome to Cloudlandia. I'm sitting out in my courtyard and it's a little bit of a cold, rainy morning. I don't know if you can hear the rain gently falling in the courtyard. It's relaxing. Dean: Do you have an? Dan: umbrella over your head. No, I'm in a. I have a covered, a covered area here that I'm sitting at about. I don't know what you call it, like a lamina or a loja, I don't know how it is, but it's a covered underroof thing, that's attached to my courtyard. Dean: What you're saying is that there's something between you and this guy. That's exactly it. Dan: I'm not getting rained on, I'm under covered, as they say. Dean: Yeah, well, it's sort of a poignant, almost like a Japanese. Stay right, yeah, this almost feels like a Japanese Zen garden. Dan: here I hear the like the little the water coming off the roof of a tile roof, so that it's very Japanese Zen actually, because the there's a spout that drains the water down into a drain. Yeah, so nice. Dean: Yeah, it's very interesting. When I was a teenager I sort of fell in love with Japanese culture. This would be early 60s, late 50s, early 60s and you know I read the literature, I looked at the artwork. I was interested in their architecture, their history, and then in my military. I was drafted into the US military and got sent to South Korea. And I'm an R and R. Rest and relaxation, that's what they called it. Dan: R and R I went to Japan. Dean: I went to twice, oh nice. And my memory is of being in the mountains, at a place where they really didn't speak English I don't know even now if they you know, having Americans who was part of their experience, but it was perfectly understandable. I mean, the hospitality was so great. But I can remember being in one of these little rooms where they had. They had sliding doors that would open up and you could see the mountain, you could see the water. And I remember it raining, but I was warm and I had tea. And I was sitting there and it sort of corresponded to what my teenage visions had been. I always remember that. Dan: That's great. I love it when stuff like that happens. Well, this would definitely be the kind of day that would be conducive to tea. Dean: And sitting out here. Dan: It was kind of a Zen garden that I have in the courtyard, so it's nice. Dean: Yeah, yeah. Speaking of Zen, there's a lot about the jump from the mainland to Cloudlandia that has a Zen-like quality to it, tell me more, tell me more, especially now with the. A lot about it, well, a lot about it. You have to imagine, in other words, that you only get as far in Cloudlandia as your imagination will go. I'm really seeing this. I'm kind of being a creative collaborator with Evan Ryan, still in his 20s, but he's been investigating artificial intelligence for the last 10 years, so he's well into it. So basically his adult life has been and he's got a very thriving business and he's got clients from all over the planet. But he wrote one book which was superb. It was called AI as your teammate and he put it together into a six-module coaching course for companies and our entire company went through that. Dan: Oh, wow. Dean: So it's six to our modules and just to the main. Purpose is just to get people over the hump that this is any scarier than any technology that they've already mastered. It's just a new technology. And it did wonders. It did wonders and I can see the last module was probably four months ago and I can see the investigations and the experiments that are going on across the company, each person sort of focusing on something different. And then Evan is writing a new book and I just shared an idea with him and maybe it be a topic that we would discuss today. But I said, there's all sorts of predictions being made by people about where AI is going and where it's going to take us, and both exciting and scary. The predictions are both exciting and scary and what I realized that all these predictions, no matter how expert the person tried to present themselves, was just one person's prediction. And more or less their prediction for everybody else was simply what they wanted to do for themselves, Right. Dan: Yeah. Dean: And I think Mark Zuckerberg and there's all sorts of people the big tech people and government people and everything, corporate people and I say you're trying to make this a prediction for the world, but it's only probably a prediction for you that this is the direction and what I realized is that there's an exponential breakthrough with AI and it's in the area of tinkering, which is a neat word, yes, Tinkering. So Evan and I talked about it and he's going to. You know, he's developing the idea as exponential tinkering. Dan: And I really like it. Oh, I like that. Dean: That's a good yeah, what a nice combination of words, because, there are kind of two words that are jarring when you put them together, that's very good. Dan: I like that a lot. Dean: Yeah, so what are you tinkering? Dan: with. So I'm tinkering with a couple of things right now and deep into the. Are you talking about technology things? Dean: No, yeah. Well, technology, or specifically AI, are you tinkering at all with it, seeing what it can do? Dan: I'm starting now to. Did you see the latest thing a couple of days ago? The release of Sora, the video creation tool. Now, that was OpenAI did that right. OpenAI has just I think it's only very limitally open to their top tier, you know, data users or whatever, but the demo reels of it you know, showing what it's capable of, and I mean it's certainly you see now where that's the final piece of the puzzle here, like two things have happened in the last 30 days that have really kind of cement where I see this going. I've been predicting here that 20, that you know, almost like the big change 1975 to 2025 will kind of look and the you know all these exponential improvements reaching the top of the asymptotic curve that there's You're using big words. Dean: Yes, so Asymptotic, asymptotic. I think that deserves a subhead for our listeners. Dan: Okay, Well, asyn, in math when you do exponential, it's exponentially increases, increases, and then it reaches a point where it's just marginally like improving slightly. You know, like there's not really the exponential leap, for instance, of going from. If we just take text, we've gone from, you know, writing it on papyrus or having people hand write stuff. Dean: Chiseled as on. Chiseled as in play. Dan: Whatever. And then Gutenberg was an exponential leap in that, but it got better in terms of when we were able to, you know, create digital photocopy and things like that, and we got to the text file where you could digitize text and that became a PDF. And now so everything you know, the functional like improvement in text, has really reached the top of. There's nowhere really to go from everything ever written available instantly on any device you have. And that same thing has been over the last 25 years, kind of cascading series of those with increasing complexity of them, right? I think it's not. That's the easiest thing to fully digitize is text. And then pictures were the next thing, that you could digitize pictures so we can transfer images, then moving pictures right? Audio, sorry, was next after text, audio images or images, videos. Now we're at the point where you know every piece of media video, audio, text or images is completely digitized. It's available on any device at any time you want it. And this next piece that's falling into place is the ability to generatively create, from description, images and videos that you can describe. And so when you take this Sora, and you take Dali and you take the all the things that are converging with the, with the AI, and we'll give them another two year runway, which would even sort of double their time that they've been in our world Mainstream they'll be fully cemented into the mainstream use. And then you look at what's happening with the release of Apple's new Air Pro goggles, or whatever they're calling them. Dean: Vision Pro. Dan: Vision Pro. Dean: And that is. You know everybody who's going to use any of this. Dan: Exponential tinkerers. Dean: Yeah, but that somebody who's doing it tinkerers. Tinkerers is just someone who's doing it for their own purposes. You know they're not trying to create something for anybody else, they're just for example, I gave you the example that I've had a real interest in. You know, I wrote a new book and I had. I was writing a new book and I had one chapter finished and it was how we put our company together, and the chapter was unique ability teamwork. That, basically, a fundamental difference between coach team members and other team members is that we everybody operates according to their own unique ability within unique ability teams. Okay, so that's that, but I've always had a fascination with Shakespeare. You know he's one of my five. Dan: Yes. Dean: You know, five lifetime role models Shakespeare, because he was not only a great poet, a great playwright, a great you know creator of, you know, creator of plays, but he was also a tremendous entrepreneur and he, you know, he created the first company that was self-sustainable and he created a new theater and everything else. So he was very entrepreneurial and seems to have made a pile through theater. And anyway, but I was always fascinated with the language form that was operating in London in the late 1500s and 1600s. So Shakespeare is 1560, 1560, 1660 years and it was called iambic pentameter and it was a structure where there's only 10 syllables per line. You get to the 10th syllable and then you go to a new line, and so I had one of my team members actually go to AI, go to chat GPT and say we would like to translate Dan's copy into iambic pentameter and it was back in 24 hours. Dan: You know came back and I was just fascinated. Dean: I was just fascinated with it because I thought differently about my own thoughts when I saw them come back in a different language form. In English but about a different structure. So I was sitting there, I was reading it and I gave it to some of our team and I said what do you think about this? And they said, wow, I get totally new thoughts from reading it. It's, you know, the basic ideas, but they're in a different language form. And I said now what I'd like to do is I hear it like it here. It's spoken, you know, by someone who was really great with Shakespeare's language. So it was a very famous actor who we have their recordings of, and so we open my team member, Alex Barley, who is British you know. So he's from the UK, so he has a feel for this type of language and he has a feel for theater. And then he worked with Mike Canig's, great friend of ours and. Mike. Mike gave him two or three other AI programs that he could take a look at and about four days later I get this wonderfully eloquent reading of a whole chapter in Iambic content and I listen to it every week. I listen to it every week and it does things for my thinking. Okay, and I've shown it to a few people. This is a you know. A number of people have listened to it and they're all say, wow, that's amazing. Dan: You did that. Dean: Why'd you do that? Why'd you do that? Dan: Why'd you do? Dean: that Just tinkering? I was just tinkering and I just. I kind of said you know, if I put this together with this and maybe put the two of them together with this, I wonder what it sounds like. And I have no intention of, I have no intention of going any further with it, but it really serves a purpose, that it really influences my own thinking and I've noticed that my writing has changed as a result of listening to this for three or four, three or four months, you know, I just I just get a different take on my own ideas. Dan: And. Dean: I call that tinkering, I just call that tinkering. Dan: I like that. Dean: And I believe that with AI, what you have, there was always tinkering in the technology world, but I think what AI does, it makes, it allows tinkering to be exponential. Dan: That's interesting. So there's, I'd say, yeah, you're, there's an artistry to it in a way. Dean: You know, in that there's, it's kind of like doing something for your own pleasure for your own yeah, and your own enhancements you know you see, you see an extension of a capability that you already have, but you can see new dimensions of the capability that you already have and that in itself is the reward, that in itself. And people say well, are you going to? You know, I tell people and they say oh, so are you going to actually produce this? And you know, you know like we produce our books. And I said no, I'm just doing it for my own reasons. Dan: I just like the feel of this. I just like the feel you know and. Dean: I do not think I'm unique in this experience. I think there's a hundred million people doing the same thing with something that kind of fascinates them. Dan: And I wonder if that's the artistic expression gene or something. I mean, that's our internal desire to chase our whims. Dean: You know, in a way, yeah, that's one of the great joys of the the reason I'm saying this is that we're always making the predictions about who the giant tech giant is that's going to dominate this and I said one I don't see it emerging. I think all of them are scrambling like mad so that they don't get left behind. But I don't think the idea of tinkering really exists in that world. You know quarterly stock prices, investments that's what they're looking for, you know, and everything else, but I don't see the dominant player, even. You know, even open. Ai is the dominant player. Dan: Have you had some experience? Have you tried the vision pros yet? Dean: No, I don't like goggles. Dan: I don't need. I mean I'm not inclined either. Dean: They're anti social. Dan: I wonder you know it's going to be. I know there'll be a lot of people at Free Zone next week that have them that are, so we'll get a chance to try that for sure. But I know my kenix has it. Dean: I know Leo as his one of the things that I always look at their past stage right now, but it'd be interesting checking their lives down six months from now whether they're actually using them. Dan: That's what I'm curious about, right Like it's so. Dean: I don't need to be first in with anything. Dan: Right, exactly, yeah, yeah, I think that this chasm it's getting, you know, I think it's getting wider and wider, this that there's even now, nuances of going deeper into Cloudlandia, because I think that's like immersively diving into Cloudlandia and I think that there's. Nick Nanton just posted a thing about some big movie director who was tweeted about. You know, just spent the day editing this is a feature movie, mainstream movie director saying you just spent the day editing in the Vision Pros with, in collaboration with his editor, on a big screen. They are theatrical, like movie screen size and just fascinated. He said. Dean: you know, no headache, no anything so I don't know, yeah well, where I think and I felt five, ten years, well, let's say five years ago when people were talking about visual reality, okay. Dan: Yes. Dean: And Peter Diamonis had a lot of proponents of this at Abundance 360 and I was sitting there and I said first of all, every everything that I've seen I find boring and the reason? because what you're seeing is the creation of one brain, and if it's not an interesting brain to begin with, the result of their creation of a VR program is exponentially less interesting. Okay, and what actual reality is good? You know, I look out in my yard and you have the same opportunity there. I look at them and I've got these seven giant oak trees in their yard, I mean they're a hundred, and ten hundred foot oak trees, and the reason I love those trees so much is nobody created them. There was no intention for this to happen. It was just a lucky acorn. Dan: Right the result of it. Dean: I mean they produce thousands, millions of acorns in our yard and it's just squirrel food you know, and and it's the nonintentionality that interests me, it's not the somebody's intention, okay, and one person's story really doesn't interest me for the first time if it doesn't include a lot of other people's stories you know, in other words. You're putting that together, so I don't know. I mean, I think there's a fundamental obstacle to all technological breakthroughs, and it's called human nature. Dan: Yeah, this is where that's. What I wonder, is the goggles? Them sound like it. Just it feels like, wow, this is a you know, unless we're at a point where I think the improvement of the vision pros is that you can actually see out of them. Dean: Well, you can see out of them and it's got the thing that I think is really going to make a difference, and that's all augmented reality. Yes, exactly In other words, you're looking at a real thing. Yeah, there are useful pictures, useful data, useful messages on it, and there's useful capabilities, in other words, there's like email and, I'm sure, the design. You know design tools and everything that you can do and that, I believe, is good, but it'll only, it'll take hold where the use of this speeds up an economic process that already makes money. But you can speed up an economic process. Dan: I'm seeing that, if everything is, you know, being shaped to drive us deeper into this cloudlandia existence here, that everything's happening in the goggles, that I was just had coffee with Stuart, my operations guy, and we were saying how it seems like there's a trend towards you know, I have you ever heard the term hostile design for architecture where the Starbucks one of the Starbucks here in Winter Haven just went under when it's 10 year renovation and they completely turned it into like a basket robin's? where it's all the character of you know a basket robin's. There's no sense of that third place kind of you know origin that Starbucks started with, where, when Starbucks was first getting started in the 90s, they had, you know, nice design, comfy chairs. It was inviting to come and get a coffee and sit and you know gather kind of thing. And now it's essentially designed with the hey, keep it moving, keep it moving kind of vibe to it. There's no, nothing about the chairs, the seating, it's just literally one long banquette with facing single wooden chairs. You know that, on and round table, so there's no comfort or invitingness to come and linger. Dean: Well, they commoditize, so you know. In other words, yeah they start off at very special places. Yeah, and you know you could go in if you could use it as an office, it could be your office all day if you were I think yeah. Dan: I think that's what happened is that post as we got into the last ten years where it became more, you know, wi-fi is ubiquitous and, you know, demanded in public spaces like that. That you know I was saying to Stuart. My theory about it is that in the 90s and early 2000s the internet was still a place that you had to go to right, like you, yeah, had to go to your computer to go there, and these third places were, of you know, an important part of you're putting that aside and you're coming to this third place to be there and as laptops and Wi-Fi and all these things made it possible that people could go and set up shop in the Starbucks and spend the whole day there, that became defeated, the whole purpose. It wasn't a third place, it was the place. 0:25:06 - Dean: You know, yeah, and the other thing it became every place. You know, I mean, when you commoditize, it's every place. And, and you know, I mean you know. And the other thing is that there was a fundamental change in the Starbucks culture and I can say exactly when it was. It was in the 90s and I think it was probably around 1995. They said there's a risky part of our future and that is we can't guarantee that we're always going to have good baristas okay, because the real right. The real skill I mean of Starbucks is who is? Where the baristas who can do the coffee, just right, and they said we can't. You know, it's too risky and that we become too dependent on these people, you know and they said we've got to make it mechanical and what they did immediately is that their espresso drinks, you know, whatever form it came in, was only 80% as good, but it was predictably 80. The moment you give away quality in order to achieve quantity, you've lost all uniqueness. Yeah. I agree, yeah and that's what they've done. And now the other thing is that they created their own competition because people seeing how a coffee operation works, they went to Starbucks University and got their degree, you know, and it probably take a year to do that and they went out and created their own independent coffee shops. So I think those unique coffee shops still exist, but they're not trying to take over the planet yeah, it's really. Dan: It's interesting. I'm looking for places like that, but you just it's kind of a sad thing. It's almost like you've talked often about the, the black cab knowledge of the drivers in London that they have London, I think London. Dean: London, birmingham and Manchester, I think they have, but the black cabs are the best cabs in the world. Yeah, okay, they're, just there's nothing to compare of what an experienced black cab driver with the black cab experience in the world. There's just nothing like it, and it takes you three years of dedicated study to even pass the test to become a black cab driver, you know and it's very interesting that all of that now can be. You know, anybody in their Honda Civic equipped with their iPhone, has the knowledge right on their phone well, actually it worked out, it didn't work out in London right, because Uber came in and they said well, you know, the Uber guys got it, but they have no feel for the city right and yeah, and so within six months of Uber coming in and actually threatening black cab developed its own Uber software, so now they have the Uber software plus the knowledge of the driver yeah, right it's like AI, an AI program defeating world champion, chess champion okay, yeah and within a year, the chess champions just said okay, we've upped the game and now it's us, plus our AI program, against each other. Dan: Yeah, it's very. You know, it's a-. Dean: Humans are infinitely smarter than technology. Dan: Yeah, it's a fascinating time to be approaching your 80th birthday right now too, you know, looking into the next decade here. Yeah, what are you guessing and betting on for the next few weeks? Dean: I'm betting that people's grasp of their past is now their trump card. Okay, that the future is completely and totally unpredictable, okay as far as I'm concerned. I mean, I think you could predict the future more in the 19th and you know the book you gave me, the 1990, the great change I would think was called the Great Change. If I think back to 1950, where I was alive, I think that the first grade teacher and I had a first grade teacher in 1950, sister Mary Josephia. Sister Mary Josephia, sometime, first grade she says the reason why you're learning this now reading, writing and arithmetic is that when you graduate from high school because nobody went to college in those days- you know, you left high school and you went and got a job. She says everybody's going to be looking in the job market at how good you are at reading, writing and arithmetic and showing up on time and finishing what you start and saying please and thank you and everything else. And she was totally correct. In 1962, exactly what she predicted was true. Okay, so try a first grade teacher in 2024, can she predict anything about what a first grader will experience 12 years later? Dan: Yeah, no chance yeah. Dean: And that's just a general condition on the planet. I just think the future is no longer predictable. So what's the unused resource? The unused resource is your past. Dan: Say more about that. What do you mean? The unused resource? Dean: Well, first of all, it's unique. I mean, if I sat down with you and asked you questions about your past and it went on for a year day in day out for a year. Not one thing that you say about your past during that year is anything but unique to you. That's true. Yeah, exactly that's where all the raw material is for creativity. It's not in the future, you know and it was so funny because I remember four or five times in abundance 360, peter would invite in people from Google, okay, and they had these moon shots, okay, and what was interesting about them? They were predicting new things in the future that hadn't been imagined yet, okay. And it seems to me like sparse ingredients, but it was what they were up to and there was presentation after presentation and they had videos on YouTube and everything else. And I said is there any customer experience in this? No, there was no customer experience. They were just making it up, you know, and they were sort of, and these teams were in competition with each other who could come up with the most convincing thing? That didn't exist. And then I kept track of it and over a 10-year period they shot all those projects down. They never went anywhere. Dan: Wow, yeah, they never went anywhere. Dean: Yeah, and I said, all you do is let's find three examples of things that people are already enjoying, and can we put them together in a new way and create something new where people already have experience? With at least a third of the new thing you know, and that's what Apple does. Apple never does anything. First they sit there and they say MP3 player, napster, making money doing this Internet. Let's put the three of them together and see where they go. Dan: Yeah, that's smart. They were doing triple plays and didn't even know it. Yeah, well, maybe they were, Maybe they were yeah that's your clever observation of it, right, exactly, yeah, put a framework over it. Dean: There's a great technology thinker by the name of Mark Mills, and he wrote a really interesting book called the Cloud Revolution. Okay, and it's really worth a read. Okay, and what he said? If you go backwards 100 years and you look for all the major technological breakthroughs that have more or less been the mainstream of the last 100 years, he says they you always discover it was never one thing, it was always three things. Dan: Oh really. Dean: He uses the radio, he uses electricity, he uses internal combustion, he uses cars, he uses airplanes, he uses, you know, motion pictures and all the major things air conditioning and everything, and he shows the three things that went together before the breakthrough was possible. Oh wow, and part of the reason is you're putting together already existing habits. Dan: Yeah, that's really. You have to piggyback on something that somebody's already doing, right. Dean: Yeah, that gives them their existing habit, even though you're adding. You know you're adding factors that are two other habits. But you have to get people something solid to stand on before you ask them to take a step into the new. Dan: What was the name of that book? Dean: again, it's called the Cloud Revolution. Okay, the Cloud Revolution. Yeah and he uses an interesting example and this is a prediction he's making for the future. He said, with reshoring take place. So that's one factor the supply chains are going to get shorter and shorter in the future, because COVID sort of proved to everybody that relying products that came from a hundred different places and required 5,000 miles of ocean travel to get to us wasn't reliable for the future products you know, foods and everything. So what? The major thing is that you're going to try to have supply chains were important with things as close as possible to where the customers are. And he said that's one trend. Okay, that's reshoring, that's that process of bringing your manufacturing and your industrialization back to close to you. That's one factor. The other factor is no longer obsolete shopping centers, Okay. And he said let's suppose that you just take every obsolete shopping center and you turn it into a combination of warehouse, factory and distribution center, Okay. Okay, All the existing infrastructure is built in. That's already zone. It's got huge parking, it's got some massive, big spaces like the big anchor stores, some massive big spaces. You already have delivery docks, you have truck docks that go underground and people go yes and everything. And he says but it's obsolete for the purpose it was created for. But he says if you think about it as a nexus point for trade supply routes in other? Words the raw material will come in and then supply routes going out to the actual customers. And he says all of a sudden you got a new use. But people are used to shopping centers, people work in shopping centers, you know and everything else he says well, you know, and they have major, usually they're situated where there's major transportation routes, there's major highways, there's, you know. I mean probably the best shopping centers are in places that have, you know, highway access. They have air airline, you know, ups, and so that he says just look, look at a lot of stuff that already exists. Put it together in a new way and people's habits already supported. Dan: That's smart. Dean: Yeah. Dan: I like those things, so that fits in with the whole. Jeff Bezos, you know what's not going to change in the next 10 years model, looking not at what's going to change, but what's not going to change, because that's what you can anchor on. Dean: Yeah, it's kind of like I'm just watching all the EV companies, the electric vehicle companies, with the exception of Tesla, because they've got a unique, established niche. I don't think any of the other companies that are based on a profit motive are making that forward, shutting, cutting back. Volkswagen is cutting back, gm is cutting back, everybody's cutting back, because they're losing anywhere from $30,000 to $70,000 on a vehicle and it doesn't look like it's going to get any better. Okay, and then, but what made it unnatural is the fact that you had to have massive government insistence for it to even get off the ground. Dan: Yeah, you just kind of hit something on the head there, because Elon Musk has definitely thrown his hat over the fence on electric vehicles and it is dominating the market for it, because he's all in on that, which is something that Ford and Volkswagen and all these companies can't do. They're not, they're only like dabbling in the electric vehicle markets, you know. Dean: Yeah they did it because there were massive subsidies, there was math, you know, and the states like California were mandating. You know, you know, and by 2035 we won't have any fossil fuel vehicles. Okay, and you know, if the strong arm of government's gonna come on and just forbid the alternative, well, of course we're going to invest our future in it. But those governments are going to be thrown out. I bet the government in California is throwing out within 10 years, I mean you know, by the way, that that just reminded me of something. Dan: I just watched the Tucker Carlson interview with Putin. Did you see that? Dean: Yeah, Parts of it. I saw a part Okay. Dan: Yeah, yeah, nothing extraordinary about that. That wasn't what I was getting to. But while Tucker was in Russia, he did a series of short Videos that were just kind of exploring what is it actually like in a, you know, post sanctioned Russia that you know, yeah, since they put sanctions in place and you know, and it was funny because he was describing, you know, like every visual that we have of, you know, communism in Russia is, you know, empty shelves and limited supply and limited Choice and utilitarian things. So he went, he did a interesting series where he went to a Russian Supermarket to see, okay, so what is it like like? What's day-to-day life like in Russia under sanctions during wartime? And it was, you know, the most fascinating like grocery store where you go in and it's the shelves are stopped with Everything you could imagine, all these things. It's a beautiful, clean store, very modern. Everything about it was amazing. They filled up their basket with what would be, you know, a week's worth of groceries for a family of four kind of thing, what you would get if you were kind of feeding a, a family of four and they, you know, found everything. They they wanted a beautifully you know, fresh baked bread, all the staples that you could need. They filled them all up. They all him and the producers kind of guessed that they would have, you know, $400 or 400 worth of groceries if they were buying it in America, kind of thing which was their frame of reference and Turns out they got all of that stuff for like a hundred and four dollars is what it's what it costs. Dean: Yeah, don't you find it fascinating that he found the one supermarket in all of Russia where that was. Dan: That's what I wonder. That's what I want. Dean: No, that's not you think he went there just have passers-by on his own, I don't like to go. Oh yeah, yeah, the Soviets had one in Moscow. It was right near the Kremlin. It was called gum GUM, if you look it up on Wikipedia. Huh, capital G, capital U, capital M, and you went in and it was just well-dressed shoppers, everything you know, I think that's that's might have been where he was. That might have been it, oh yeah, and it's, and it's a show place, it's a show play and that's what they found when they found out the history of it. Shoppers would go in and they would come out the front door and then they go around the block, go through the black door Backdoor and give back everything that they had bought, and then it was restocked on the shelves. Dan: Oh boy. Dean: They were all actors. Dan: Oh, wow, very interesting. I wondered the same thing, because they did. He went to a subway station that he admittedly said was the most beautiful. So we never seen a subway station as nice anywhere in in America and it was. They showed the footage of it. You know, beautiful artwork and chandeliers and steam, cleaned cleanliness and, no, no graffiti, all of those things. And it did have the sense of. Is this a show place? Because there's an interesting YouTube channel. There was a gentleman from the UK and his channel is called bald and bankrupt and what he does is he goes just solo with a single camera and he was touring all these Soviet Territories. All the outposts, you know, like that were the height of the thing, to compare, and every one of it is Just like everything is run down. And you know all of the Soviet Union, you know post Communism is completely, you know, run down. And what you would expect, right, what you would that, your Vision of it, and I think that you kind of just hit it on the head. That's that it's more likely. Dean: That's like a show place or a yeah that that subway system was put in the 1930s. Okay, they had the boss of it, was cruise ships, cruise ships came in the fame Because he put in. But there was. There was no Limit on cost and there was no limit on how many people died. Building, they asked, made about 20,000 workers died. Putting in the subway system Okay and and, but if those are not cost you pay any attention to, then you can build anything in the world. But, if you wanted to go to another city and see the subway, they wouldn't let you do that. You could only see the subway. That they, because subways were a bigger deal you know in the 1930s or 1920s. Then they are now. You know, because most people don't use the subways. But in Europe, you know, where people don't have cars and they live in very dense populated areas, subways make sense. I mean 80 percent of the Public transportation in the United States I'm talking about buses and subways and commuter trains is the greater New York area that once you get outside the New York area, only 20 percent of the public public Transportation public transportation exists because everybody's got private transportation. Dan: Yeah exactly right. Dean: I mean you got your own. I mean you got a plush Travel vehicle called the Tesla X. You know it's kind of neat. You don't use it 99% of the time, but it's nice having you know. Dan: You know what I said. I was talking about you. Yesterday the I was had to drive somewhere that was about an hour away, just over an hour Actually. Dan said a new high watermark for my migration north. I went just about a half an hour north of I for the first time since. What's it like? Dean: I mean do you need oxygen? Dan: I mean you know I was using the self-drive, which is just name. You know it's only in named and as it has a nervous breakdown if you take your hand off the wheel for more than 30 seconds at a time. But I said you know Dan Sullivan has it figured out. Dan Sullivan has had self-drive since 1997. Dean: You've had true self drive, self automatic, self drive you know it's an interesting thing, but what I notice, you know I'm just developing the reason. This thing about the past is interesting because I'm writing my new quarterly book right now and it's called Everything Is Created Backward, and what I mean everything that sticks is actually created by starting with the past and picking the best of, and I think three things is really a formula. I mean, there might be things where it's five things, but I think three is useful because you can go looking for three, okay, and what I'm seeing is that the tech world has basically ground to. A lot of people don't know this, but the investment part, the venture capital part of the tech world, has just hit a wall. I mean, there's a massive amount of money available, but nobody wants to invest it because so many things promised as new things in the last 10 years really haven't amounted to anything. It's about, I think about less, maybe around 10% of IPOs. You know, initial public offerings have panned out Okay. That's a high risk that you have a nine you know, a nine to one chance of losing your money if you invest in something new, and I think the hype factor for getting investment has lost its energy. Dan: Yeah, that's changes everything. This changes everything, oh that's no good, then that's a sure sign that it's doomed. Yeah, this changes everything should be your signal to run away. Dean: Yeah, and you know I mean, but it does change everything for certain individuals and this is the mistake. It's like Joe Polish calls this cruel optimism. Dan: You know cruel optimism Okay. Dean: Yeah, and he has a great take on this, and he said that that when it comes to you know, because he's very interested in addictions and how one gets off an addiction, and he says there's thousands of predictions that if you do this and do this, you get a work for you. And he said what's true about it is it'll work for somebody, okay, but it's their willingness for it to work that actually makes it possible. And so there's a lot of human agency to things turning out the way you want. If you take complete ownership and it has to work for you, probably it'll work. But if you think it's going to be done to you and you don't have to do anything probably it won't work. Yeah, that's a very yeah, but I thought it was. But he says it's very cruel Because when it doesn't work and it doesn't work, and it doesn't work, your addiction gets more powerful. Dan: I said to somebody I've been talking about. I've often talked about the difference between, in marketing, a slot machine versus a vending machine, and that's a great analogy. It's often the way that most businesses take on marketing. They put money in the slot machine and they pull the lever and they hope that something happens and they're surrounded in a room by all the other entrepreneurs. Dean: Yeah, we got two out of three. Or we got two out of three oranges. Dan: We got a trend going here, that's right, so everybody's pulling their slot machine and they're all in the same room and somebody hits the jackpot and they all flock over to that machine. Look at the crowd, See see, see, it works. They're like yeah, trying to do the same thing. And then you know every all the testimonials that you see. That's exactly what that reminded me of. It's cruel optimism that sometimes see it does work, but they're usually talking about something that happened quickly and to a great extent and once. And it's not the same as the predictable vending machines. Not every time I put in the dollar I get $10 out. Dean: But you know, one of them has. One of them comes with a dopamine factor and the vending machine doesn't come with the dopamine factor. Dan: That's the truth, isn't it? Yeah, but we're all seeking that excitement of the the lot machine. Yeah, it's a cruel optimism, that's funny. Dean: I think it's a good. I think it's a good title. You know, he everything but and. But. It has that somebody else's formula for the future is going to work for you. You know, so I have a. You know I have a little saying that in order to create a more, bigger and better future, you have to first start by creating a bigger and better past. And the reason is the past is all yours to work with. The future is nobody's to work with. Dan: Right. Dean: Yeah, and so my feeling is the greatest breakthroughs with the new vision pro, you know and you know the other AI technologies that are coming along with it is that my feeling is that the best breakthroughs for this will be actually an industrial work, where you're actually dealing with existing engineering. You're existing with existing infrastructure and I think quality control is going to go way up, as people can check out every system you know and they look at, you know they go backstage, they go into a boiler room and they can do a check with their goggles on of every piece of machinery and they have a checklist, does this check and does this check and nothing gets missed. And I think it's going to. The great greatest breakthrough is going to be an industrial quality control. I think that's where it's going to be most used Wow and warfare. I mean all the 35, the latest jets. They operate as six pilot, six plane units. And all, every one of the pilots is aware of the other five pilots and what they're doing. Okay, and they operate as this six person unit, their radar allows them to see 500 miles out in all directions. Okay, and they can see any threat coming, probably two or three minutes before the threat sees them, which makes a big difference, you know. So yeah, somebody said, all breakthroughs happen in three ways, all human, technological breakthroughs. Number one is weaponry. Okay, that's number one, number two is toys and number three is porn. Dan: So there's a triple play right there in the making. Dean: There's a triple play. I mean, if you can check off the box, if this is good for warfare, it's good for play and it's good for porn you got yourself a winner. Dan: Oh my goodness. Dean: That's funny, I like within three days. The biggest complaint about Apple's new vision pro was you couldn't do popcorn on it. Dan: You can't I mean, it's funny, isn't it? That's the way, that's the thing, oh man. Dean: Now, instead of being horrified by that, you're being told something important. Dan: Yes, exactly that's great. So this, this is the week, dan, this is our yeah, so we'll be in. Dean: Orlando at the four seas, in Palm Beach at the four seasons. So Thursday evening will be arriving there. I've got all day Friday completely free. And but we already have Saturday for dinner and Sunday dinner in the calendar with others who have requested it. Dan: Okay so so I got lots of time. Okay, so that's my plan Initially. I may come down Friday then, but Saturday was when I was going to arrive, so maybe, let's you know, put Saturday lunch for sure, yeah, if that works for you yeah, yeah, yeah, yeah and yeah. Dean: So we're completely, you know, completely flexible with those days All my materials for printing have to be in by Tuesday this week. Dan: Okay, so you're gonna. You're a relax and it's all underway. Dean: Yeah, it gets printed out of Chicago and it'll be sent to the team when they get to Palm Beach. It'll be in the four seasons and they'll just have all the materials for the workshop. Dan: Yeah, I'm looking forward to it. Okay, well, worst case scenario be Saturday at lunch, maybe Friday. I'll come down on Friday, okay. Dean: What'd you get? What'd you get out of today? Dan: Fascinating, I think this whole. I like this idea of the exponential thinker. Dean: I think that I will be there. You should chat with him about it. There's so many people. Dan: I'm looking, really looking forward to seeing everybody it's. I can't believe it's been a year. Dean: You know, yeah, yeah, yeah. So there, anyway, I think we're gonna have a good. We're gonna have a good, a good event. We have about 70 free zoners and we have another 90 guests. Dan: Oh my goodness, wow, okay, great. Yeah, so hopefully that will yield some new free zoners too. Dean: Yeah, okay, dean, see you on Saturday. Thanks, dan, bye, and just let Becca know, you know, and she'll work things out. Dan: Okay, that sounds great, okay, okay, thanks, bye, bye.

Contributions of structural variations to the asymptotic mixed-mode coupling Factor in red giant stars by Chen Jiang. on Thursday 13 October The advent of ultra-precise photometry space missions enable the possibility of investigating stellar interior with mixed modes. The structural variations induced by the discontinuity of the chemical composition left behind during the first dredge--up is an important feature in the stellar mid-layers located between the hydrogen-burning shell and the base of the convective zone of red giants, as the mixed-mode properties can be significantly affected by these variations. In this paper, the contributing factors to variations of the mixed-mode coupling factor, $q$, are discussed with stellar models. In general, the structural variations give rise to a subtle displacement in the Lamb frequency and a sharp change in the buoyancy frequency, which lead to variations in the value of $q$ computed using the asymptotic formalisms that assuming a smooth background free of structural variations. The impact of these two factors can be felt in detectable mixed modes in low-luminosity red giants. Furthermore, the different nature of variations of the two characteristic frequencies with radius near the base of the convective zone, produces a sudden increase in $q$ in evolved red giants. This is followed by a quick drop in $q$ as the star evolves further along the red giant branch. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.06904v1

The asymptotic structure of gravity in the asymptotically flat case will be described in four and higher spacetime dimensions by making central use of the Hamiltonian formalism. Special emphasis will be paid to the case D=5. How the relevant infinite-dimensional asymptotic symmetry group (BMS group) emerges at spatial infinity will be explained. Non-linear structures which appear in five (and higher) spacetime dimensions will be discussed.

Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: How BoMAI Might fail, published by Donald Hobson on April 7, 2022 on The AI Alignment Forum. This post is me looking at 1905.12186.pdf and giving some ideas on how it might fail. Firstly, I would like to point out that I think the design in this paper does buy you some amount of marginal safety when dealing with slightly superhuman AI's, and that it still gives opportunity to perhaps get something useful out. Failure mode 1) A lack of optimization doesn't mean a lack of danger. Even after the episode ends, the box may contain dangerous optimized items. Given that the box was specified to contain only a human, (And some cloths) this suggests the most dangerous thing that could leave is probably some form of meme. For example, suppose the AI finds a very convincing argument that humans should do whatever AI's want. This is a very good solution to the problem of hacking the human into giving the AI whatever answer it wants. (Which is pretty much what this AI was programmed to do, although it may sometimes give good answers on occasions where that is easier than hacking the operator) Once the human exits the box, the idea can go viral. Failure mode 2) What does the "Asymptotic optimality" mean in practice. Imagine a world containing BoMAI. The BoMAI comes up with a plan to take over the world after this episode has ended. It tries this plan. Lets imagine a magic angel interferes with this plan, stopping it the moment the episode ends. So the BoMAI is somewhat puzzled, and tries again. Eventually BoMAI will learn that plans involving taking over the world after the end of the episode never work, and so it will stop doing them. This means the magic angel only has a finite amount of work to do. Plans that involve taking over the world are assumed to receive a lower rating within the episode. The smaller the difference in reward between a plan that also takes over the world after the episode, and a plan that purely optimizes within an episode, the more slowly such taking over world plans disappear. Leading in the limit to failure mode 1. Of course, in reality, the magic angel doesn't exist, and the AI succeeds in taking over the world. Failure mode 3) Criticizing the box. The mentor has no vacuum between them and the font of all evil (the AI). There is also no Faraday cage, and a screen facing the mentor that is vulnerable to all sorts of hacking. Therefore the mentor can be hacked. There is no vacuum between the mentor and the AI, so if the mentor can claw through concrete, they gain hardware level access to the AI. They can then disable the pressure sensors and any other systems that end the episode. Now the airlocks can be opened by using whatever mechanism is used to open the airlocks at the end of an episode. There must be some point where information from the pressure sensors feeds into the AI system to stop the episode. This point, and the pressure sensors themselves, are vulnerable to electromagnetic and sonic interference from the AI. Suppose the AI has a bunch of cooling fans it is in control of, and by vibrating them all in just the right way, it can cause all the sound waves to constructively interfere right on the solder joint between a pressure sensor and the AI's circuits. This allows it to work the solder loose, slowly breaking that connection. The AI can now encourage the human operator to smash the glass. The AI bootstraps nanotech. It turns out there was a sophisticated and easily hackable piece of proto-nanotech just sitting around, in the form of a bacteria just sitting on one of the AI's chips. By carefully controlling the electromagnetic, thermal and sonic emissions of its hardware, the AI can hack that ribosome. The bootstrapped nanotech can tunnel through the walls of the box and take over the world. There are other flaws in the "nothing can get thro...

6 Ways our government keeps us controlled. Replacing Private rights with public rights There are 3 types of Rights Public rights (privileges or franchises )- rights exist between the Government and Citizens/inhabitants Apply to your status not LAND Created by congress in civil statutes Private rights - exist in relationship between Human beings (non-residents) and GOV Attach to land not status protected by common law (there is a difference between common law and statutory law) Constitutional Rights -exist between human being and government attached to LAND - not status Two types of property Absolute : shared /w no one qualified : shared Government established to " keep private & public property separate They steal private property by WILLFULLY confusing public rights with private rights and privileges Purpose of the government Protect the PRIVATE RIGHTS No not your public rights (meaning claim any status, or accept any benefit connected to this status"citizen" "Resident" "spouse" "driver"-or apply for or use government property in connection with otherwise private financial transactions you cannot be free from the system Promote JUSTICE legally defined as :the right to be LEFT ALONE Government that doesnt protect you from its own abuses of authority to convert private property & rights into public rights w/oEXPRESSED, DEMONSTRATED EVIDENCE of your consent to the conversion is a government mafia Two types of GOVERNMENT Government by CONSENT (DE JURE )- dont enforce civil obligation with out express consent Terrorist Government- operate by force or fraud (DE DE FACTO GOVERNMENT) PURPOSE OF GOVERNMENT: Identify , isolate, instruct, and punish those who INURE OTHERS IN MY opinion that is why the pandemic was orchestrated in such a way that it made everyone not complying with the mandates the "Injurers" of others. They have made the public believe that non compliance does harm to others when the evidence to this reality for that is non existent People who dont understand this will see arrest/detentions/ job loss/ medical tyranny/ mandatory vaccines/ as Justice WHY? Because Laws that punish OFFENSES that dont injure others are UNJUST" So, by propagating that these "non-compliants" are injuring others (Asymptotic )it releases their conscious of feeling bad for allowing people to suffer tyrannical abuse from government public officials while they stand idly BY. --- Support this podcast: https://anchor.fm/overcominglife/support

Aki Vehtari (Aalto University) gives the OxCSML Seminar on Friday 7th May 2021 Abstract: I discuss the use of the Pareto-k diagnostic as a simple and practical approach for estimating both the required minimum sample size and empirical pre-asymptotic convergence rate for Monte Carlo estimates. Even when by construction a Monte Carlo estimate has finite variance the pre-asymptotic behaviour and convergence rate can be very different from the asymptotic behaviour following the central limit theorem. I demonstrate with practical examples in importance sampling, stochastic optimization, and variational inference, which are commonly used in Bayesian inference and machine learning.

It's a whole network of interacting conscious agents outside of space time, a vast social network. And we've made the rookie mistake of assuming that our headset, VR, our visualization tool, is the final reality.” [17:55] “no matter how much consciousness explores its possibilities, it could never come to the end of its own possibilities. And so it's in a never ending self exploration.” [31:22] “And right now we're sort of stuck on this little headset, three dimensions, small amount of color that we can see and so forth. Just, we thought it was the whole world. No, it's just it's a little headset.” [33:08] “...we’re chasing that consciousness itself is only about exploring new possibilities of experience.” [35:55] “So the reason I'm doing this is because I can't even imagine a specific color that I've never seen before, I can't imagine in four dimensions. In other words, I take it as a given that I'm deeply, deeply limited in my imagination. And I need all the tools I can get to help me step outside of my headset and try to guess, the unfathomable outside of there.” [52:47] “There seems to be reward for absolute silence, no concept whatsoever, and out absolute precision on the other hand. And there's no reward for sloppy thinking in the middle.” [1:51:57] “don't hold on to anything dogmatically right as that's the sort of the point explore and then be the first to kill off the things that you know really don't make sense don't don't hold on to them so it's an anti dogmatic point of view” [1:54:37] FOLLOW (NAME): Website:http://www.cogsci.uci.edu/~ddhoff/ Email: ddhoff@uci.edu Twitter: https://twitter.com/donalddhoffman?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor Instagram: https://www.instagram.com/donalddhoffman/
Chances are, you have seen the night sky before. Thou looketh to the Heavens: what does thou see? It is likely that one sees a few, or a few thousand, glimmering stars, some shining brighter than others; some orange, red, blue; some massive, some small; some luminous, some dim. It is likely that you have seen at least a somewhat dark night sky sometime in your past life, as I assume most of you have gone camping or hiking or biking, sometimes, or often if you are similar to I, during the night. In the Northern winter, the night sky is bedazzling your eyes with thousands of points of beauty, as it does in the summer. In the Northern winter, the brightest of the stars show their brilliance and luminance to our eyes; Sirius, Regulus, Adhara, Betelgeuse, Rigel, Aldebaran, Procyon, Capella, Bellatrix, Alnitak, Alnilam, and Mintaka all showcase their complexion during these months. In the Northern summer, the Milky Way, the dense band of stars that appears to us as a glimmering wave of milk, conveys its own particular brilliance. In the Northern summer, the brilliantly-lit Deneb, Vega, Altair, Antares, Arcturus, Sadr, and the great stars of Sagittarius and Ursa Major dominate our vision. Upon seeing this prodigious assemblage of nuclear fusion, our brains begin to fail to understand the immensity of the universe in which we live. Even when gazing upon the meager 3,000 visible stars in our night sky, we are humbled by the formidable collection which exists above our heads. This episode and the subsequent episode delves deep into the great stellar immensities lying below our noses.

The idea that there exists an ongoing effort to achieve a “two-state solution” in Israel and Palestine - often referred to as The Middle East Peace Process™ - is uniformly taken for granted by American media. This "two-state solution" is always at different stages of viability, yet never quite works out. Presidents fail to achieve it; Palestinian violence makes it "more difficult"; Israeli settlements are "unhelpful" to it. But how honest is this effort? How are nonstop obituaries for a phantom "process" helping to maintain the status quo, or worse? How much does this infinitely regressive effort deliberately mask an ongoing and active policy of ethnic cleansing by the Israelis in the West Bank and Gaza? In Part II of this two-part episode, we discuss this "two-state" racket with Rebecca Vilkomerson of Jewish Voice for Peace.

Andrii Khrabustovskyi works at our faculty in the group Nonlinear Partial Differential Equations and is a member of the CRC Wave phenomena: analysis and numerics. He was born in Kharkiv in the Ukraine and finished his studies as well as his PhD at the Kharkiv National University and the Institute for Low Temperature Physics and Engineering of the National Academy of Sciences of Ukraine. He joined our faculty in 2012 as postdoc in the former Research Training Group 1294 Analysis, Simulation and Design of Nanotechnological Processes, which was active until 2014. Gudrun Thäter talked with him about one of his research interests Asymptotic analysis and homogenization of PDEs. Photonic crystals are periodic dielectric media in which electromagnetic waves from certain frequency ranges cannot propagate. Mathematically speaking this is due to gaps in the spectrum of the related differential operators. For that an interesting question is if there are gaps inbetween bands of the spectrum of operators related to wave propagation, especially on periodic geometries and with periodic coeffecicients in the operator. It is known that the spectrum of periodic selfadjoint operators has bandstructure. This means the spectrum is a locally finite union of compact intervals called bands. In general, the bands may overlap and the existence of gaps is therefore not guaranteed. A simple example for that is the spectrum of the Laplacian in which is the half axis . The classic approach to such problems in the whole space case is the Floquet–Bloch theory. Homogenization is a collection of mathematical tools which are applied to media with strongly inhomogeneous parameters or highly oscillating geometry. Roughly spoken the aim is to replace the complicated inhomogeneous by a simpler homogeneous medium with similar properties and characteristics. In our case we deal with PDEs with periodic coefficients in a periodic geometry which is considered to be infinite. In the limit of a characteristic small parameter going to zero it behaves like a corresponding homogeneous medium. To make this a bit more mathematically rigorous one can consider a sequence of operators with a small parameter (e.g. concerning cell size or material properties) and has to prove some properties in the limit as the parameter goes to zero. The optimal result is that it converges to some operator which is the right homogeneous one. If this limit operator has gaps in its spectrum then the gaps are present in the spectra of pre-limit operators (for small enough parameter). The advantages of the homogenization approach compared to the classical one with Floquet Bloch theory are: The knowledge of the limit operator is helpful and only available through homogenization. For finite domains Floquet Bloch does not work well. Though we always have a discrete spectrum we might want to have the gaps in fixed position independent of the size of our domain. Here the homogenization theory works in principle also for the bounded case (it is just a bit technical). An interesting geometry in this context is a domain with periodically distributed holes. The question arises: what happens if the sizes of holes and the period simultaneously go to zero? The easiest operator which we can study is the Laplace operator subject to the Dirichlet boundary conditions. There are three possible regimes: For holes of the same order as the period (even slightly smaller) the Dirichelet conditions on the boundary of holes dominate -- the solution for the corresponding Poisson equation tends to zero. For significantly smaller holes the influence on the holes is so small that the problem "forgets" about the influence of the holes as the parameter goes to zero. There is a borderline case which lies between cases 1 and 2. It represents some interesting effects and can explain the occurance of so-called strange terms. A traditional ansatz in homogenization works with the concept of so-called slow and fast variables. The name comes from the following observation. If we consider an infinite layer in cylindrical coordinates, then the variable r measures the distance from the origin when going "along the layer", the angle in that plane, and z is the variable which goes into the finite direction perpendicular to that plane. When we have functions then the derivative with respect to r changes the power to while the other derivatives leave that power unchanged. In the interesting case k is negative and the r-derivate makes it decreasing even faster. This leads to the name fast variable. The properties in this simple example translate as follows. For any function we will think of having a set of slow and fast variables (characteristic to the problem) and a small parameter eps and try to find u as where in our applications typically . One can formally sort through the -levels using the properties of the differential operator. The really hard part then is to prove that this formal result is indeed true by finding error estimates in the right (complicated) spaces. There are many more tools available like the technique of Tartar/Murat, who use a weak formulation with special test functions depending on the small parameter. The weak point of that theory is that we first have to know the resulat as the parameter goes to zero before we can to construct the test function. Also the concept of Gamma convergence or the unfolding trick of Cioranescu are helpful. An interesting and new application to the mathematical results is the construction of wave guides. The corresponding domain in which we place a waveguide is bounded in two directions and unbounded in one (e.g. an unbounded cylinder). Serguei Nazarov proposed to make holes in order to make gaps into the line of the spectrum for a specified wave guide. Andrii Khrabustovskyi suggests to distribute finitely many traps, which do not influence the essential spectrum but add eigenvalues. One interesting effect is that in this way one can find terms which are nonlocal in time or space and thus stand for memory effects of the material. References P. Exner and A.

In this dissertation we investigate long-term interest rates, i.e. interest rates with maturity going to infinity, in the post-crisis interest rate market. Three different concepts of long-term interest rates are considered for this purpose: the long-term yield, the long-term simple rate, and the long-term swap rate. We analyze the properties as well as the interrelations of these long-term interest rates. In particular, we study the asymptotic behavior of the term structure of interest rates in some specific models. First, we compute the three long-term interest rates in the HJM framework with different stochastic drivers, namely Brownian motions, Lévy processes, and affine processes on the state space of positive semidefinite symmetric matrices. The HJM setting presents the advantage that the entire yield curve can be modeled directly. Furthermore, by considering increasingly more general classes of drivers, we were able to take into account the impact of different risk factors and their dependence structure on the long end of the yield curve. Finally, we study the long-term interest rates and especially the long-term swap rate in the Flesaker-Hughston model and the linear-rational methodology.

Demonstrates, through several examples, how simple asymptotic information and a few explicit computations can capture a fairly accurate bode diagram which thus is useful for insight into any subsequent design. Also demonstrates the use of MATLAB to form exact plots and shows how these compare to the hand drawn sketches.
Builds on the previous video by showing how some asymptotic information in the Bode plot can be obtained with minimal or no computation. This asymptotic information can be used as the basis for suprisingly accurate Bode diagram sketching for systems with multiple simple poles and zeros and requires minimal extra computations.

We propose a general framework to design asymptotic preserving schemes for the Boltzmann kinetic kinetic and related equations. Numerically solving these equations are challenging due to the nonlinear stiff collision (source) terms induced by small mean free or relaxation time. We propose to penalize the nonlinear collision term by a BGK-type relaxation term, which can be solved explicitly even if discretized implicitly in time. Moreover, the BGK-type relaxation operator helps to drive the density distribution toward the local Maxwellian, thus natually imposes an asymptotic-preserving scheme in the Euler limit. The scheme so designed does not need any nonlinear iterative solver or the use of Wild Sum. It is uniformly stable in terms of the (possibly small) Knudsen number, and can capture the macroscopic fluid dynamic (Euler) limit even if the small scale determined by the Knudsen number is not numerically resolved. It is also consistent to the compressible Navier-Stokes equations if the viscosity and heat conductivity are numerically resolved. The method is applicable to many other related problems, such as hyperbolic systems with stiff relaxation, and high order parabilic equations.

Speaker: Dr. C. Bordenave Abstract: Consider N queues with non-homogeneous packet arrivals. The queues share a common communication channel. At the beginning of each timeslot, if queue i has a packet, it attempts to access the channel with probability p_i. This attempt is successful when no other queue attempts to access the channel. For arbitrary N, the stability region of such queuing system is a long standing open problem. However as the number of queues N goes to infinity, it is possible to compute the asymptotic stability region. This is a joint work with David McDonald (Ottawa) and Alexandre Proutiere (Microsoft).

In this talk we discuss about asymptotic properties of solutions of both, Volterra integral and Volterra difference equations. For the Volterra difference equations, we derive stability conditions based on the direct Lyapunov method and present some examples to illustrate them.

We present a statistical process depending on a continuous time parameter whose each margin can arise a Generalized Hill's estimator. In this paper, the asymptotic normality of the nite-distributions of this family are completely characterized for when the underlying distribution function lies on the maximum domain of attraction. The ratio of two different margins of the statistical process characterizes entirely the whole domain of attraction. Its asymptotic normality is also studied. The results permit in general to build a new family of estimators for the extreme value index whose asymptotic properties can be easily derived. For example, we give a new estimate of the Weibull extreme value index and we study its consistency and its asymptotic normality. Travail joint avec Gane Samb Lo (Université de Saint-Louis, Sénégal).

In this thesis, we prove that many asymptotic invariants of closed manifolds depend only on the image of the fundamental class under the classifying map of the universal covering. Examples include numerical invariants that reflect the asymptotic behaviour of the universal covering, like the minimal volume entropy and the spherical volume, as well as properties that are qualitative measures for the largeness of a manifold and its coverings, like enlargeability and hypersphericity. Another important class of invariants that share the above invariance property originates from universal volume bounds. The main example is the systolic constant, which encodes the relation between short noncontractible loops and the volume of a manifold. Further interesting examples are provided by the optimal constants in Gromov's filling inequalities, for which we show that they depend only on the dimension and orientability. Considering higher-dimensional generalizations of the systolic constant, a complete answer to the question about the existence of stable systolic inequalities is given. In the spirit of the results mentioned already, we also prove that the stable systolic constant depends only on the image of the fundamental class in a suitable Eilenberg-Mac Lane space.

We investigate the asymptotic behavior of a particular family of weighted sums of independent standardized random variables with uniformly bounded third moments. We prove that the empirical CDF of the resulting partial sums converges almost surely to the normal CDF. It allows us to deduce the almost sure uniform convergence of empirical distribution of the empirical periodogram as well as the almost sure uniform convergence of spectral distribution of symmetric circulant random matrices. In the special case of trigonometric weights, we also establish a central limit theorem and a large deviation principle. It is a joint workwith W. Bryc.

Most epidemiological studies suffer from misclassification in the response and/or the covariates. Since ignoring misclassification induces bias on the parameter estimates, correction for such errors is important. For measurement error, the continuous analog to misclassification, a general approach for bias correction is the SIMEX (simulation extrapolation) originally suggested by Cook and Stefanski (1994). This approach has been recently extended to regression models with a possibly misclassified categorical response and/or the covariates by Küchenhoff et al. (2005), and is called the MC-SIMEX approach. To assess the importance of a regressor not only its (corrected) estimate is needed, but also its standard error. For the original SIMEX approach. Carroll et al. (1996) developed a method for estimating the asymptotic variance. Here we derive the asymptotic variance estimators for the MC-SIMEX approach, extending the methodology of Carroll et al. (1996). We also include the case where the misclassification probabilities are estimated by a validation study. An extensive simulation study shows the good performance of our approach. The approach is illustrated using an example in caries research including a logistic regression model, where the response and a binary covariate are possibly misclassified.

We prove that the quasi-score estimator in a mean-variance model is optimal in the class of (unbiased) linear score estimators, in the sense that the difference of the asymptotic covariance matrices of the linear score and quasi-score estimator is positive semi-definite. We also give conditions under which this difference is zero or under which it is positive definite. This result can be applied to measurement error models where it implies that the quasi-score estimator is asymptotically more efficient than the corrected score estimator.

This paper focuses on an extension of zero-inflated generalized Poisson (ZIGP) regression models for count data. We discuss generalized Poisson (GP) models where dispersion is modelled by an additional model parameter. Moreover, zero-inflated models in which overdispersion is assumed to be caused by an excessive number of zeros are discussed. In addition to ZIGP regression introduced by Famoye and Singh (2003), we now allow for regression on the overdispersion and zero-inflation parameters. Consequently, we propose tools for an exploratory data analysis on the dispersion and zero-inflation level. An application dealing with outsourcing of patent filing processes will be used to compare these nonnested models. The model parameters are fitted by maximum likelihood. Asymptotic normality of the ML estimates in this non-exponential setting is proven. Standard errors are estimated using the asymptotic normality of the estimates. Appropriate exploratory data analysis tools are developed. Also, a model comparison using AIC statistics and Vuong tests (see Vuong (1989)) is carried out. For the given data, our extended ZIGP regression model will prove to be superior over GP and ZIP models and even ZIGP models with constant overall dispersion and zero-inflation parameters demonstrating the usefulness of our proposed extensions.

Poisson regression models for count variables have been utilized in many applications. However, in many problems overdispersion and zero-inflation occur. We study in this paper regression models based on the generalized Poisson distribution (Consul (1989)). These regression models which have been used for about 15 years do not belong to the class of generalized linear models considered by (McCullagh and Nelder (1989)) for which an established asymptotic theory is available. Therefore we prove consistency and asymptotic normality of a solution to the maximum likelihood equations for zero-inflated generalized Poisson regression models. Further the accuracy of the asymptotic normality approximation is investigated through a simulation study. This allows to construct asymptotic confidence intervals and likelihood ratio tests.

We consider a Poisson model, where the mean depends on certain covariates in a log-linear way with unknown regression parameters. Some or all of the covariates are measured with errors. The covariates as well as the measurement errors are both jointly normally distributed, and the error covariance matrix is supposed to be known. Three consistent estimators of the parameters - the corrected score, a structural, and the quasi-score estimators - are compared to each other with regard to their relative (asymptotic) efficiencies. The paper extends an earlier result for a scalar covariate.

A polynomial structural errors-in-variables model with normal underlying distributions is investigated. An asymptotic covariance matrix of the SLS estimator is computed, including the correcting terms which appear because in the score function the sample mean and the sample variance are plugged in. The ALS estimator is also considered, which does not need any assumption on the regressor distribution. The asymptotic covariance matrices of the two estimators are compared in border cases of small and of large errors. In both situations it turns out that under the normality assumption SLS is strictly more efficient than ALS.

We propose goodness of fit tests for testing generalized linear models and semiparametric regression models against smooth alternatives. The focus is on models having both, continuous and factorial covariates. As smooth extension of a parametric or semiparametric model we use generalized varying coefficient models as proposed by Hastie&Tibshirani (JRSS B, 1993). A likelihood ratio statistic is used for testing, and asymptotic normality of the test statistic is proven. Due to a slow asymptotic convergence rate a bootstrap approach is pursued. Asymptotic expansions allow to write the estimates as linear smoothers which in turn guarantees simple and fast bootstrapping. The test is shown to have sqrt(n) power, but in contrast to parametric tests it is powerful against smooth alternatives in general.

This article considers a linear regression model with some missing observations on the response variable and presents two estimators of regression coefficients employing the approach of minimum risk estimation. Asymptotic properties of these estimators along with the traditional unbiased estimator are analyzed and conditions, that are easy to check in practice, for the superiority of one estimator over the other are derived.

This article considers a linear regression model in which some observations on an explanatory variable are missing, and presents three least squares estimators for the regression coefficients vector. One estimator uses complete observations alone while the other two estimators utilize repaired data with nonstochastic and stochastic imputed values for the missing observations. Asymptotic properties of these estimators based on small disturbance asymptotic theory are derived and the impact of departure from normality of disturbances is examined.

We are concerned with the asymptotic theory of semiparametric estimation equations. We are dealing with estimation equations which have a parametric component of interest and a functional (nonparametric) nuisance component. We give sufficient conditions for the existence and the asymptotic normality of a consistent estimation equation estimator for the parameter of interest. These conditions concern the asymptotic distribution of the estimation function and of its derivative as well as the effect of the functional nuisance part in the estimation equation. In order to treat the nonparametric component we introduce a general differential calculus and a general mean value theorem. For the nonparametric part in the estimation equation we distinguish two cases: the situation of a (classical) nuisance parameter and the case of a so called working parameter. As a special case we get regularity conditions for estimation equations with finite dimensional nuisance or working parameter. As an example we present the semiparametric linear regression model.

This paper considers the estimation of coefficients in a linear regression model with missing observations in the independent variables and introduces a modification of the standard first order regression method for imputation of missing values. The modification provides stochastic values for imputation. Asymptotic properties of the estimators for the regression coefficients arising from the proposed modification are derived when either both the number of complete observations and the number of missing values grow large or only the number of complete observations grows large and the number of missing observations stays fixed. Using these results, the proposed procedure is compared with two popular procedures - one which utilizes only the complete observations and the other which employs the standard first order regression imputation method for missing values. It is suggested that an elaborate simulation experiment will be helpful to evaluate the gain in efficiency especially in case of discrete regressor variables and to examine some other interesting issues like the impact of varying degree of multicollinearity in explanatory variables. Applications to some concrete data sets may also shed some light on these aspects. Some work on these lines is in progress and will be reported in a future article to follow.
