THZ 252 - You're Where You Need to Be

Massive bandwidths are available in the sub-terahertz bands, but the coverage of a cellular network exploiting those frequencies will be spotty. The 6GTandem project tries to circumvent this issue by developing a dual-frequency system architecture that jointly uses the sub-6 GHz and sub-THz bands. In this episode, Erik G. Larsson and Emil Björnson are visited by Dr. Parisa Aghdam, Technical Lead of 6GTandem and Research Manager at Ericsson. The discussion starts with potential use cases, such as extended reality services in stadiums and connected factories. The conversation then focuses on hardware aspects, such as how to build a distributed antenna system using plastic microwave fibers and amplifiers so that sub-THz signals can be transmitted from many different locations. You can read more about the EU-funded project and its partners at https://horizon-6gtandem.eu/ Music: On the Verge by Joseph McDade.

Experimental compound shown to block effects of multiple harmful drugs | New Atlas (01:20) Naloxone is a medication used to reverse or reduce the effects of opioids, which is commonly used to counter decreased breathing in an opioid overdose. A new chemical shows promise for serving a similar role, but it also works on non-opioid drugs.Known as Pillar[6]MaxQ (P6AS) It was developed at the University of Maryland, and it was recently tested on lab animals for the first time. Once P6AS is injected into the bloodstream, it binds with the molecules of certain other compounds and sequesters them into its central cavity, where they're surrounded by an outer layer of water.Altering the bound compound's chemical, physical and biological qualities.Resulting in blocking their effects on the body. In the mice model tests, P6AS proved to be highly effective at mitigating the effects of fentanyl – which is an opioid – but also on methamphetamine, which is not.Additionally it showed to do well at neutralizing non-opioid drugs such as PCP, ecstasy and mephedrone. Captured drug molecules were subsequently passed in the urine It should be noted that in the case of methamphetamine dosing, P6AS had to be injected within five minutes in order to be effective. Would likely be too small of a window in the real world The scientists are now working on lengthening those times, for opioids and non-opioids alike. It'll be several years before P6AS is available for general use.   'Mars' interior is not behaving,' active mantle plume reveals | Live Science (06:30) NASA's InSight mission has detected quakes and even evidence of recent volcanism around one Martian region, known as Elysium Planitia. Now, they think they know why this activity is occuring. This study appears to be the first active mantle plume discovered on the Martian surface.Findings suggest that Mars may be cooling significantly more slowly than scientists had anticipated.  Mars lacks separate tectonic plates; instead, its crust is a single continuous sheet sitting atop the mantle.Therefore scientists think the volcanic activity on Mars must be the result of mantle plumes. Mantle plumes are columns of hot, rising material in the Earth's mantle that can cause volcanic activity and create hotspots on the Earth's surface.Mantle lies between the crust and the core. In short this finding suggests that Mars is still cooling, just more gradually than scientists had assumed. The study concludes by stating:“A plume beneath Elysium Planitia indicates that the surface volcanic flows and seismic activity are not isolated events, but part of a long-lived, actively sustained, regional system, with implications for the longevity and astrobiological potential of subsurface habitable environments.” In other words, the presence of this regional system suggests that there may be areas below the surface of Mars that have conditions that could be suitable for life to exist.   Haptic hydrogel "skin" simulates touch in VR and AR | New Atlas (10:36) Engineers at the City University of Hong Kong have developed a thin, wearable electronic "skin" that provides tactile feedback to users in VR and AR.Called WeTac Most haptic feedback devices are big and bulky, and require complex setups and tangles of wires.WeTac system looks like one of the neatest iterations The system is made of a rubbery hydrogel that sticks to the palm and front of the fingers, connected to a small battery and Bluetooth communication system located in a 5-cm2 (0.8-sq-in) patch on the forearm. That battery can be recharged wirelessly. The hydrogel is dotted with 32 electrodes spread across the palm, thumb and fingers, and electrical currents are sent through these to produce tactile sensations.Can simulate a range of experiences: catching a tennis ball, feeling a virtual mouse walk across your hand, or a negative feedback such as touching a digital cactus. Not interested in the video game applications, but this device could even help users remotely control robots, transmitting the tactile sensation of what the robot is grasping to its human operator.   Pill technology releases molecules by exposure to UV light | Brighter Side News (15:37) Researchers from Tel Aviv University developed a new technology that will allow controlled encapsulation and release of molecules by exposure to UV light. The researchers estimate that the technology will lead to further development of delivery systems for controlled release of biomolecules and drugs in the body by external stimuli, using light. Development was inspired by viral compartments formed by the measles virus.The virus forms compartments that host all the reactions involved in the formation of new viral particles called viral factories. Dynamic and liquid-like structures that are formed inside the host cell The researchers designed a peptide (short minimalistic protein) which forms compartments that resemble viral factories for encapsulation of biomolecules.  Additionally, they incorporated a unique element to the peptide sequence that enables a control of the encapsulation and release of molecules by irradiating the compartments using UV light. Dr. Ayala Lampel, who supervised this study stated on the potential of this technology:“This technology opens opportunities for biomedical and biotechnological applications including encapsulation, delivery and release of drugs, protein, antibodies or other therapeutic molecules.”    A new water-based switch is thousands of times faster than current semiconductors | Interesting Engineering (21:04) Researchers have developed a water-based switch that becomes conductive thousands of times faster than current state-of-art semiconductor-based switches. Used in computers, smartphones, and wireless communications. Transistors are a crucial component in electronic devices because they can control the flow of electricity through a circuit, effectively acting as a switch. The building block of modern electronics, allowing for the amplification and switching of electronic signals. The faster a transistor can switch, the faster a computer system can perform tasks. To create this water-based switch:The researchers used a highly concentrated sodium iodide dissolved water and sprayed this salty water from a custom-made nozzle as a thin sheet only a few microns (micrometers) thick. Next, the water jet was excited with a short but powerful laser pulse at 400 nanometers (nm).This bumps electrons out of the dissolved salts, increasing the conductivity of water. Since the laser pulse is so fast, the water becomes conductive and behaves almost like a metal. All of this happens in less than one trillionth of a second, which translates to potential computer speeds in the terahertz (THz) range.Making this water-based switch faster than the fastest semiconductor switching speed currently known. Terahertz devices could someday enable much faster computing, and water-based technology could offer a more environmentally friendly alternative to rare-earth metals.   

Compact jets dominate the continuum emission in low-luminosity active galactic nuclei by J. A. Fernández-Ontiveros et al. on Monday 21 November The disappearance of the accretion disc in low-luminosity active galactic nuclei (LLAGN) leaves behind a faint optical nuclear continuum whose nature has been largely debated, mainly due to serious observational limitations in the IR to UV range. We combine multi-wavelength sub-arcsecond resolution observations -- able to isolate the genuine nuclear continuum -- with nebular lines in the mid-IR, to indirectly probe the shape of the extreme UV continuum. We found that 8 of the nearest prototype LLAGN are compatible with pure compact jet emission (self-absorbed synchrotron plus the associated self-Compton component) over more than ten orders of magnitude in frequency. When compared with typical radio galaxies, the LLAGN continua show two peculiarities: $i)$ a very steep spectral slope in the IR-to-optical/UV range ($-3.7 < alpha_0 < -1.3$; $F_nu propto nu^{alpha_0}$); and $ii)$ a very high turnover frequency ($0.2-30, rm{THz}$; $1.3,rm{mm}-10,rm{mu m}$). These attributes can be explained if the synchrotron continuum is mainly dominated by thermalised particles at the jet base or corona with considerably high temperatures, whereas only a small fraction of the energy ($sim 20%$) would be distributed along the high-energy power-law tail of accelerated particles. On the other hand, the nebular gas excitation in LLAGN is in agreement with photo-ionisation from inverse Compton radiation ($alpha_{rm x} sim -0.7$), which would dominate the nuclear continuum shortwards of $sim 3000$ r{A}. Our results suggest that the LLAGN continuum can be dominated at all wavelengths by undeveloped jets, powered by a thermalised particle distribution, similar to the behaviour observed in compact jets of quiescent black hole X-ray binaries. This has important implications in the context of galaxy evolution, since LLAGN may represent a major but underestimated source of kinetic feedback in galaxies. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.09828v1

Simons Observatory: Broadband Metamaterial Anti-Reflection Cuttings for Large Aperture Alumina Optics by Joseph E. Golec et al. on Tuesday 11 October We present the design, fabrication, and measured performance of metamaterial Anti-Reflection Cuttings (ARCs) for large-format alumina filters operating over more than an octave of bandwidth to be deployed on the Simons Observatory (SO). The ARC consists of sub-wavelength features diced into the optic's surface using a custom dicing saw with near-micron accuracy. The designs achieve percent-level control over reflections at angles of incidence up to 20$^circ$. The ARCs were demonstrated on four 42 cm diameter filters covering the 75-170 GHz band and a 50 mm diameter prototype covering the 200-300 GHz band. The reflection and transmission of these samples were measured using a broadband coherent source that covers frequencies from 20 GHz to 1.2 THz. These measurements demonstrate percent-level control over reflectance across the targeted pass-bands and a rapid reduction in transmission as the wavelength approaches the length scale of the metamaterial structure where scattering dominates the optical response. The latter behavior enables the use of the metamaterial ARC as a scattering filter in this limit. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2208.02292v2

Radio Variability and Broad-Band Spectra of Infrared Galaxies with and without OH Megamaser Emission by Yu. V. Sotnikova et al. on Tuesday 11 October We study the radio variability of galaxies with and without sources of hydroxyl (OH) megamaser radiation based on the continuum radio measurements conducted in 2019-2022 with the radio telescope RATAN-600 at frequencies of 2.3, 4.7, 8.2, and 11.2 GHz. Presumably, radio continuum emission significantly affects the megamaser radiation brightness, therefore, such a characteristic as the variability of radio emission is important for determining the OHM galaxies parameters. With additional data from the literature, the parameters of radio variability on a time scale up to 30 years were estimated. The median values of the variability index for 48 OHM galaxies are in the range $V_{S}=0.08$-$0.17$, and for 30 galaxies without OH emission they are $V_{S}=0.08$-$0.28$. For some individual galaxies in both samples, flux density variations reach 30-50%. These sources either are commonly associated with AGNs or reveal active star formation. Generally, the variability of luminous infrared galaxies with and without OH megamaser emission is moderate and of the same order of magnitude on long time scales. From estimating the spectral energy distribution parameters in a broad frequency range (from MHz to THz), we determined the spectral index below 50 GHz and the color temperatures of dust components for megamaser and control sample galaxies.

What you'll learn in this episode: Why designing a bracelet is the same as designing a bridge Why jewelry has its own design language, separate from the language of fine art or craft How Warren learned about the engineering of jewelry making by doing repairs Why the architecture of a piece of jewelry is as important as its visual design Warren's tips for creating beaded jewelry that will withstand the stress of movement About Warren Feld For Warren Feld, beading and jewelry making endeavors have been wonderful adventures. These adventures over the past 32 years have taken Warren from the basics of bead stringing and bead weaving, to wire working and silver smithing, and onward to more complex jewelry designs which build on the strengths of a full range of technical skills and experiences. He, along with his partner Jayden Alfre Jones, opened a small bead shop in downtown Nashville, Tennessee, about 30 years ago, called Land of Odds. Over time, Land of Odds evolved into a successful internet business. In the late 1990s, Jayden and Warren opened another brick-and-mortar bead store – Be Dazzled Beads – in a trendy neighborhood of Nashville. Together both businesses supply beaders and jewelry artists with all the supplies and parts they need to make beautiful pieces of wearable art. In 2000, Warren founded The Center For Beadwork & Jewelry Arts (CBJA). CBJA is an educational program, associated with Be Dazzled Beads, for beaders and jewelry makers. The program approaches education from a design perspective. There is a strong focus on skills development, showing students how to make better choices when selecting beads, parts and stringing materials, and teaching them how to bring these together into a beautiful, yet functional, piece of jewelry. Warren is the author of two books, “So You Want to Be a Jewelry Designer: Merging Your Voice with Form” and “Pearl Knotting…Warren's Way,” as well as many articles for Art Jewelry Forum.

He and his partner Jayden opened their jewelry studio and supply store, Land of Odds/Be Dazzled Beads, due to financial worries. But coming to the world of jewelry as an outsider is what has given Warren his precise and unique perspective on how jewelry should be made. He joined the Jewelry Journey Podcast to talk about the language of jewelry design; why jewelry making should be considered a profession outside of art or craft; and why jewelry design is similar to architecture or engineering. Read the episode transcript here.    Sharon: Hello, everyone. Welcome to the Jewelry Journey Podcast. This is a two-part Jewelry Journey Podcast. Please make sure you subscribe so you can hear part two as soon as it comes out later this week.    Today, my guest is jewelry designer Warren Feld. Warren wears several hats. He has an online company called Land of Odds. He has a brick-and-mortar store, Be Dazzled Beads, and he's a jewelry designer. He's located in Tennessee. He has been a jewelry designer for decades and has written a book called “So You Want to Be a Jewelry Designer,” which sounds very interesting. The book sets up a system to evaluate jewelry and discusses how designing jewelry is different from creating crafts or being an artist. Warren will tell us all about his jewelry journey today. Warren, welcome to the program.   Warren: Sharon, I'm so excited to be here with you.   Sharon: So glad to have you. Tell us about your jewelry journey. Were you artistic as a child? Did you study jewelry? How did you come to it?    Warren: I think I was artistic as a child, but my parents and teachers, my guidance counselors in high school, discouraged it. They put me on a track to be either a doctor or a lawyer, so I never had artistic training. In my thirties, I got into painting with acrylics. Not in a deep way, but in some artistic way. I never formally studied art. I became a health care administrator, and I was a professional hospital administrator at several hospitals. I was a policy planner in healthcare for the governor of Tennessee. I was director of a nonprofit healthcare agency. When I was around 35, I experienced a major burnout. I didn't like healthcare and I felt very disconnected. I was doing a great job, but I just didn't feel it.    At the same time, I met my future partner and wife, Jayden. It was a recession, and Jayden was having trouble finding a job. At one point I said, “What can you do?” and she said, “I can design jewelry,” and I said, “We can build a business around it.” I thought it would also be a good idea to sell the parts, and it worked. We first had a garage sale, where she made a lot of jewelry and sold a lot of parts, and we made $7,000. Maybe it was a fluke. So, six weeks later, we tried it again. We made the same jewelry, got the same parts, and made $4,000. So, we thought we were onto something. We eventually did the Nashville Flea Market and craft shows. We had a little store in downtown Nashville. We have a bigger store in downtown Nashville now. It worked. It was really around her jewelry designing and my business sense. I made some jewelry, but it was just to make money.   Sharon: Wow! So, you have two businesses. You have an online business, and you have the brick-and-mortar. Tell us about Land of Odds and Be Dazzled Beads. Tell us about the differences.   Warren: Originally it was Land of Odds. Jayden was the designer. We made jewelry, but it was more like I put a bead on a piece of leather and tied it in a knot. Eventually I started learning. While working at learning silversmithing, I did a lot more complex things, but she was the designer. She had country music artist clients and did a lot of custom work. The first few years, I really made jewelry just to make money. I didn't see it as an art form. It wasn't my passion. I wasn't interested, but one thing I noticed was that everything I made broke. It was really bad, and I was clueless. This was in 1987. There was no internet, no jewelry or bead magazines. Nashville did not have a jewelry-making culture, so everything was trial and error, things on fishing lines, things on dental floss. I didn't know how to attach a clasp, didn't know about clasps. Everything was so trial and error, experimental.    At some point, I started taking in repairs. That was a really strategic move and a major turning point, because I got to see how other people made things and made bad choices because of what broke. I got to talk to the wearers, and they told me how they wore it, what happened when it broke, where it broke, lots of inside stories. I started formulating some things, and I started putting them to the test and making jewelry. I was in my mid-to-late thirties, and I started getting interested and focused on the construction and the architecture, not quite the art form. Jayden's health also declined. She lost a lot of dexterity in her hands to be able to keep making jewelry. She retired, and I started making the jewelry and doing the custom work. The business started getting organized around my work. That was Lands of Odds. We were downtown in Nashville.   Sharon: At Be Dazzled Beads, you teach a lot of classes. You sell beads. You do everything.   Warren: It just evolved. It had to do with the fact that we were downtown. Nashville, at the time, was what Greenwich Village in New York was. It's a lot of little specialty shops, a lot of excitement. It was really high-end, very sophisticated. It was so successful that the big companies started moving in, Hard Rock Café, Planet Hollywood, Nascar Café, Wildhorse Saloon. When the city decided to redevelop the area for them, they took away 6,000 parking spaces in 18 months, and parking went from $2 to $20 a day. We lost all our customers really fast, and tourists changed. They were looking for low-end souvenirs, not high-end jewelry, so our business collapsed.    We put ourselves in Chapter 11 bankruptcy, and the liability is under my name. I closed Land of Odds, the physical store, and I put the assets under Jayden's name. We opened a little shop in a little house, and Jayden wanted to call it Be Dazzled. At the same time, I was developing Land of Odds as an online business. Be Dazzled was a real place in a store. About a year after declaring bankruptcy, I got out of bankruptcy and the catalogue took off. We were doing really well all of a sudden, and I combined both businesses again. So, I just had this horrible business name, Land of Odds/Be Dazzled Beads. We managed those as two separate businesses, but it was really one business.   Sharon: So, you were online way before Covid or anything.   Warren: I was online in 1995. I was one of the first catalogues online. We're still online. It's a little hard to compete today online, but we're still online.   Sharon: That's interesting because so many jewelers are not. You call yourself a jeweler. I don't mean you're not a jeweler; you are, but they don't work with beads. They work with silver; they work with gold. So, it's unusual.    Warren: No matter what the materials, you end up with something with a hole in it or a loop on it so you can string it on or dangle it. I taught myself wire working, fiber art, micro/macro maze, silversmithing. Even though the tools are different, the materials are different, when you're designing a piece of jewelry, you end up thinking through the same kinds of issues. The focus on parts was another lucky break because it made me realize early on that jewelry design was quite different than art or craft.    I started as a painter. When I first started making jewelry, I tried to paint it. I was very frustrated because I couldn't get the colors I wanted. You can't squish the beads together; you can't do little nuances and subtleties like you can do with paint. There are these annoying gaps of light, negatives spaces you can't control, and they destroy the whole idea of color. You have three-dimensional objects that reflect and refract light differently. It changes from room to room with lighting, the sun, the position of the person, how they're moving. I have some beads in the store, green, transparent beads that cast a yellow shadow. You can't duplicate that with paint, but you have to worry about if the jewelry starts to look weird on a person because you picked the wrong materials or the wrong colors. Jewelry applies to the person wearing it. You don't want that to happen as a designer.    So, I realized that whether it's beads or string materials, findings, whatever you're using, they assert their needs within the piece of jewelry. It's not just for the visual grammar, the color and pattern and texture, but they have needs for architecture. They affect some of the functions based on materials you pick, and the durability and how the piece moves. They affect the desirability and the value, how people perceive the piece. So, I began to see that I had to start with the parts and understand how they want to be expressed within a three-dimensional object that's going to adorn someone's body and move and meet someone's psychological and social needs. It's very focused on the parts.    What I was doing as a jewelry designer was very different than what I had done as a painter, as an artist. The lights went on, and it just was really intriguing. I struggled and dealt with it. It was very exciting and enjoyable to figure out, with that green bead that has the yellow shadow, what effect does it have on the piece, on the person wearing it, on people seeing it? I asked those questions, and that was really important. I was lucky to start with the parts and the business and not start with just designing jewelry and worrying about the visual grammar. Then I realized, both from being in business as well as teaching students, that most jewelry designers are very naïve to the impact of the parts. They're very focused on the visual, the color. They don't realize that so much more is going on in a piece of jewelry, so they don't think about managing it.   Sharon: So that's how you came to write this book, “So You Want to be a Jewelry Designer”?   Warren: Right.   Sharon: Wow! Being a painter and working in different materials, you're all over the place.    Warren: I had been thinking about or trying to write this book for at least 20 years. Having all these insights, I wanted to write them down. I would write them down in these articles, sometimes fun articles and sometimes very straightforward, more academic articles, and I struggled with how to pull this all together. I was getting ideas about what was important. One of my goals is to say that a jewelry designer is not an occupation. It's not a substantive art. It's really a profession. It has its own discipline, its own way of thinking and writing and doing and asking questions, solving problems. It's a profession, but how do I make it that way? I've worked that way pretty much on principle.    At one point, an education professor in town said that I might be interested in ideas about literacy and how you teach literacy to students. While I was researching that, I came across the idea of disciplinary literacy. This is an example of how a historian has to think very differently than a scientist. They use different evidence. The historian has to infer from different pieces of writing and histories and costuming to come up with an idea about cause and effect. A scientist has this rational, step-by-step approach for coming up with an idea of cause and effect. They think differently. They use different evidence. I thought, “Well, that sounds like me as a jewelry designer. I think differently than artists.” I've had to think differently than artists because as an artist, my designs weren't successful.    That was the organizing principle, disciplinary literary. So then, what does it mean? What does someone have to know if they have to comprehend it? When you say someone's fluent in design, what does that mean? How do you believe it's real? What's nice was that I had done all this writing, and everything started clicking into place. The organizing principle wasn't as much of a struggle as it was to try to put it together as an idea of you need to learn A, B and C.    You need to learn about design elements and how to decode them, but in a way like you're learning how to read them or write them or speak them. You have color. You can put colors together and create a sense of movement, another design element. Color is very independent, but movement depends on your positioning of color or line or whatever to get a sense of movement as a design element. So, here we have independent and dependent variables, vowels or consonants. Some of the design elements sounded like vowels and some sounded like consonants. How do you put it together? I realized you could put together a couple of design elements, like a T and an H in word, and you could know that E will work next. Another element or one of its attributes might work next, but a Z won't work. THZ doesn't work. That happens with design elements when you're trying to put them together. When you understand design elements as sort of an alphabet, then you begin to formulate meaning and expression and words, and the words can get more and more complex.    So, you realize you're talking about composition. You're arranging design elements, and you have to arrange them in a way that they can be constructed together, which is another element. Then you want to manipulate them because you want to control as best as you can someone's reaction to it. You want them to like it, to want to wear it, to want to buy it. This is all controlling meanings, as you're taking something universal, where everyone knows what they mean. A certain color scheme, everyone knows it's satisfying, but a simple color scheme in jewelry might be boring. It might be monotonous or it might not fit the context. It might not show power or sexuality or compliance, whatever you're trying to do with your jewelry. You have to change that scheme a little bit, perhaps color it differently.    So, I'm going through these ideas and working them together with literacy. You want someone to be able to identify problems, identify solutions. You want them to understand how to bring all these elements and arrangements together in a certain kind of form, sometimes with a theme. And towards what end? You have to have an end. I struggled with this. What's the end? What the jewelry is trying to get to, is it the same as an artist? And it's not. In art, it's about harmony with a little variety. In jewelry design, that could be monotonous, not exciting enough. In jewelry design, you want the piece to go beyond evoking an emotional response. You want it to resonate, excite, be just a little bit edgy so people want to touch it or wear it or buy it. They don't just want to say it's beautiful. You want to bring them the piece of jewelry so they actually will put it on, keep it on, cherish it, show it around, collect it. It has to do something more than an art. In the end, it has to do partly with how it resonates.    It seems to have more levels to it. It has to feel finished, and in order to feel finished, it has to be parsimonious. In art, there's a concept called economy. You use the fewest colors to achieve your balanced end, but it's very focused on the visual. In parsimony, you focus on every aspect of design, from the visual to the architectural and textual to the psychological. Parsimony means you can't add or subtract one piece without making it worse. You've reached some kind of optimal set of all the design elements, all the understandings of other people that you're bringing into the piece, all your understandings that you're imposing on the piece. If it's parsimonious, it feels finished, and that's a success. So, you go a little bit beyond what an artist does for your piece of jewelry.   Sharon: Are these different in craft? I'm sorry; that's what I'm trying to understand. Are they different in craft or fine arts?   Warren: In craft, your goal is to end up with something. Ideally, it should have some appeal, but it's got to be functional. You just end up with something. In art, it's got to be beautiful. It's doesn't have to be functional. In art, you judge jewelry like it's a painting or sculpture, like it's sitting on an easel. In jewelry design, you can only judge it as art as it's worn. It's not art until it touches the body, and that brings in all kinds of elements, the architectural, psychological, sociological, physiological. Jewelry functions in a context and you have to know what that means. So, it's different.    Sharon: It's only a piece of jewelry when it touches the body? Is that the same for metal and beads, for any kind of jewelry?   Warren: It is. You have art jewelry, let's say. It's art when it's on an easel on display. It's jewelry when it's worn. You can appreciate it as a piece of art, but to me, as a jewelry designer, I want to appreciate it as a piece of jewelry. So, it's got to be understood as it's worn. You have to see it in motion. You have to see it in relationship to the body, the costume, the context. It has to meet the artist's intent, what they wanted to do, and the wearer has to want to wear it. It must fulfill other needs, too. So, it's much more complex than dealing with a painting.

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: Interspecies diplomacy as a potentially productive lens on AGI alignment, published by Shariq Hashme on August 24, 2022 on The AI Alignment Forum. You wake up tomorrow, and find out that super-smart and powerful aliens are arriving here in 10 years. We don't know anything about them other than the fact that they're super smart and powerful: e.g, their minds run on giant computers at THz clock speeds, they can integrate planets' worth of sensor data at once, they can do direct mass to energy conversion in their spaceships, they have weapons capable of destroying our planet in an instant, etc etc. What do you, personally, do? What should humanity overall do? I think the answers to these questions shine a very important light on overlooked AGI alignment strategies. Rather than seeing the arrival of AGI as a technological change, we can see it as the arrival of a potentially competing / potentially collaborating species. Approximate intuition pump: humans :: AGI : animals :: humans -- if you were an emu (about to be hunted to extinction), how would you negotiate with the humans? If you were a monkey, how would you negotiate with the humans? What are the frameworks we would use to negotiate with supersmart powerful aliens, or which animals might use to negotiate with people? creating an ultimate ground rules moral framework: if we can create a moral framework which every species could agree to to improve the stable equilibrium of our interspecies game (where the lowest stable equilibrium is violence), then it might be convincing for an AGI coming out of our human values to maintain that ultimate ground rules moral framework. my best idea for that framework is some version of "information is sacred": I have no idea how exactly to measure information, but I think it all sort of ends up working out. preservation of information: we must try to maintain as much information as possible. most of the universe could be compressed quite a bit, but not humans: our incompressability is what gives us moral worth. the same could be said of animals. how do you determine what can actually be compressed well? it's not physically possible to do perfectly, but you can have heuristics. this is also a good reason to keep animals in special wildlife conservation areas. unfortunately it might accord quite a high moral valence to hard drives: that's fine if humans still make it out in the end continuation of computation: storing the mind state of a person isn't enough. you want their mind state to continue forwards. so somehow, we care about counterfactual future information and not just current information. obviously it's hard to know that for sure: but we could always have opinions and guess. preference maximisation: in some sense, information wants to become more information and not die out (regardless of how exactly we measure information). this is based off of the environment of the information. this might be way too difficult to do with the limited computational resources in our universe, but the ultimate moral way to treat an alien species is to give them access to a computer with infinite memory and time in which they can "maximise their information", in many different ways: so like simulating humans living 1000s of different lives. through understanding their values, use diplomacy to cajole them into better coordination. animals have a very hard time appealing to human values (e.g, dogs asking for attention): and AGI values might be much further away from human values vs animal values from humans. but: maybe not!! fight militarily. we will lose, but some humans will still think this is a good idea. use trade/other mutual benefit to improve cooperation. nation states coordinate much better when there is some kind of mutual benefit. e.g, humans provide some kind of entertainment or other ...

On July 21st, 2018, Lana Clayton was spotted running into the road by a motorcyclist. She had found her husband, Steve, collapsed and unresponsive at the bottom of the stairs. The police arrived at the Clayton home along with Steve's nephews. Although the police initially believed Steve had died from a heart attack, there were many red flags during the investigation. Lana was a nurse but had made no attempt to revive her husband. She also denied Steve had a will and pushed for cremation to avoid any tests being run on the body, After Steve's nephews grew suspicious of Lana's behavior, they requested a toxicology report and autopsy, It turns out Steve had tetrahydrozoline, or THZ, present in his system. THZ can be found in eye drops, such as Visine, and can kill someone if consumed. Lana's story quickly began to unravel and soon found herself at the center of the investigation. Listen now to hear the full story!

Vært: Henrik Heide Medvirkende: Bjørn Godske, Andreas Lindqvist og Jens Ramskov I denne uges Transformator havde vi nær sagt ‘Hvad sagde vi?' For selvom det ikke er så klædeligt at være bagklog, er det svært at lade være, når det pludselig er en stor historie i medierne, at der ikke bliver produceret tilstrækkeligt med grøn strøm til at imødekomme det store behov, vi står overfor morgendagens elektrificerede samfund. For det har vi her i Teknologiens Mediehus gjort opmærksom på det sidste år. Bjørn Godske ridser problemerne op. To-fire kystubåde bør stå helt i toppen af Søværnets ønskeliste for militært isenkram, lyder det fra både borgerlige partier og forsvarskilder. Den danske ubådskapacitet blev udfaset i 2004, men Søværnet vil allerede kunne dykke igen om få år, hvis politikerne skriver kontrakt med den eneste oplagte leverandør. Den gamle definition af sekundet ved hjælp af cæsium-133 er ved at være forældet. Optiske atomure baseret på strontiumatomer, der har en karakteristisk frekvens omkring 429 THz, er nu blevet så pålidelige og almindelige, at man i standardiseringsorganisationer overvejer, om tiden er moden til at skifte definition. Links PtX-skåltalerne glemmer to problemer Politikere vil have ubåde tilbage: Militæranalytiker anbefaler tysk model Sekundet er snart modent til at få en ny definition Forskere måler tidsforskelle mellem toppen og bunden af en lille atomsky CPH:DOX: Into the ice CPH:DOX: Fire of love

Foundations of Amateur Radio When you become a member of the amateur radio community you become part of a small group of humans who know and understand certain aspects of life. That's not to say that others don't share this or that the knowledge is unique or special, but radio amateurs are required to know this before they receive their license. In the past I've spoken about how getting a license is like receiving a key that opens the door to the world of radio communications. It's one of the more accessible ways to grab hold of this key and it's the recipe for life long learning. During the week a friend of mine, a newly minted amateur, pointed out that this represents something that the general population isn't aware of or attaches little in the way of value to. The interconnectedness of radio spectrum is something that radio amateurs take for granted. To us it's obvious. A transmitter on 3585 kHz is fundamentally the same as one on 92.1 MHz. A key fob on 434 MHz is similar to a computer on 2.45 GHz as is a laser on 500 THz or an X-ray machine on 30 PHz. As a radio amateur we're taught that the radio spectrum is a continuous phenomenon and that spectrum is shared among users with specific rules around interference and interaction. Another thing we know as radio amateurs is the difference between the front and the back of a Yagi-antenna. We know about radiation patterns, about the ionosphere and how the sun and sun-spots interact with some of our activities. The point is that our knowledge, it's fair to say, specialised knowledge, even at the lowest level of licensing, exceeds that of the general public. This is all by way of background because this leads to something that I learnt during the week. As amateurs we have a responsibility to be custodians of that knowledge, that is, to care for it and to ensure its accuracy and to preserve that knowledge. For some amateurs that means that they want this information to be exclusive, but for me it means that this information should be shared and nurtured and encouraged in those people who make choices based on incorrect information. For example, as a radio amateur it's my duty to inform a person who is contemplating breaking the radio spectrum licensing rules that they are doing so. Not because I'm a regulator, but because I have specialised information that they lack. Importing a radio module that's using a frequency that's not available in your country is an example of something that I am compelled to point out. I know that some amateurs take this compulsion to the next level and become a de-facto police officer attempting to enforce those restrictions. I understand where that comes from, but I also know that this is not my role and it's not your role. If you feel strongly enough about a transgression, perceived or real, there are plenty of ways to deal with that. Reporting the offence to the regulator is one option for example. Knowing which end is the front of a TV antenna means that you can point out a mistake to a home-owner about the direction their antenna is pointing at, but it doesn't mean that you need to climb on their roof to turn it around. I've said many times before that having an amateur license is a privilege. It's a gift, even if you worked hard for it, it was given to you, bestowed on you by the regulator in your country. It seems to me that having such a gift means that it should be treated as such. As radio amateurs we're not entitled to a license, nor are we entitled to transmit. We're granted permission to do so. I think that it's important to keep that in the back of our minds when we set out to educate those around us. As for the education itself. It pays to consider what you take for granted when you're giving advice. Telling a person about Wi-Fi propagation through a home is a complex topic. You can make the explanation as hard or as simple as you want, but don't expect that the person receiving the advice has the same background information or interest that you have. I was once told by a statistician about how various statistics worked and what their background was. I was translating a program from Modula-2 into WingZ hyper-script. I didn't care about how it worked, just that the provided code did what it was supposed to and that what I wrote did the same thing. I had no interest in becoming a professor in statistics, despite the earnest instruction enforced on me by my employer 30 years ago. It's been said that you must learn from the mistakes of others. You can't possibly live long enough to make them all yourself. What and how we teach those around us can be the seed of something bigger. I may well have become a statistician if the information had been tailored to my requirements, but that chance was lost 30 years ago. I think it's a great way to consider what we teach and how.

One in a series of talks from the 2019 Models of Consciousness conference. Stuart Hameroff Center for Consciousness Studies, University of Arizona, Tucson, Arizona The Penrose-Hameroff ‘Orchestrated objective reduction’ (‘Orch OR’) theory suggests consciousness arises from ‘orchestrated’ quantum superpositioned oscillations in microtubules inside brain neurons. These evolve to reach threshold for Penrose ‘objective reduction’ (‘OR’) by E=h/t (E is the gravitational self-energy of the superposition/separation, h is the Planck-Dirac constant, and at the time at which Orch OR occurs) to give moments of conscious experience. Sequences, interference and resonance of entangled moments govern neurophysiology and provide our ‘stream’ of consciousness. Anesthetic gases selectively block consciousness, sparing non-conscious brain activities, binding by quantum coupling with aromatic amino acid rings inside brain proteins. Genomic, proteomic and optogenetic evidence indicate the microtubule protein tubulin as the site of anesthetic action. We (Craddock et al, Scientific Reports 7,9877, 2017) modelled couplings among all 86 aromatic amino acid rings in tubulin, and found a spectrum of terahertz (‘THz’) quantum oscillations including a common mode peak at 613 THz. Simulated presence of 8 different anesthetics each abolished the peak, and dampened the spectrum proportional to anesthetic potency. Non-anesthetic gases which bind in the same regions, but do not cause anesthesia, did not abolish or dampen the THz activity. Orch OR is better supported experimentally than any other theory of consciousness. Filmed at the Models of Consciousness conference, University of Oxford, September 2019.

Foundations of Amateur Radio How far can I talk on radio? A question that regularly hits the enquiring minds of people who are not (yet) radio amateurs is one about distance. For both amateurs and those who are not ye) inducted into our community the concept of distance speaks in ways that other parts of our hobby don't. It's a simple concept, between these two points, how far can you talk? The interesting thing to me about this phenomenon is that distance isn't a metric that we as amateurs use for anything other than calculating repeater coverage and then only for frequencies that are line-of-sight. If you're not an amateur then this might be unexpected or even illogical. Let me give you two questions: How far can you talk in amateur radio? - and - How far does light shine? If you're an amateur you'll know that those two questions are pretty similar, if not identical for certain frequencies, but if you're not, then these two questions appear completely unrelated to each other. Let me start with something that you might not realise. If you tune to a local AM radio station, let's say ABC 720 in Perth. It's located in the AM broadcast band and the number of the station, 720, is the frequency at which it's transmitting. 720 kHz, or 720 thousand Hz. If you had a radio capable, you could turn the dial to the right, and after passing 810 Radio National, eventually, if you kept turning to the right, you'd find ABC Classic FM at 97.7fm in the FM broadcast band. The station indicator, 97.7 is again the frequency, 97.7 MHz, or 97.7 million Hz. So, 720 and 97.7 are both on the same dial, just at different ends. Now if your radio was capable, you'd be able to keep winding it to the right, and after passing by Wi-Fi, at 2.4 GHz, or 2.4 billion Hz, you'd eventually come across light. Green light for example is about 560 THz, or 560 trillion Hz. You could keep going and end up with even more exotic stuff, like X-rays and Gamma-rays, in the exahertz range, a 1 with 18 zeros, but you get the point. Radio and light are the same thing. If fact, there are experiments around that are using light for Wi-Fi communications. So, How far does light shine is the same thing as How far can you talk in amateur radio? Before you start complaining about when it's different, let me point out that the only difference between these two is the frequencies at which we're comparing, with the characteristics that come with that. I'll get to that in a moment. Look at light. If you have a light bulb that's bright enough, you can see it in full daylight. If it's dark outside then you'll need less of a light bulb to see it. If it's raining, or if there is smoke in the air, you'll need more. If there's a wall between you and the bulb, you'd need a pretty bright light to shine through the wall, but you already know this. Covering up a torch with your palm shows the bones in your hand. Light gets through different parts of your hand in different ways. Another thing you've seen is when you put a straw into a glass and it looks like it's broken. That too is related to how light travels through different materials. You may even have been underwater in a pool and looked up to see a reflection. That too is a phenomenon familiar in amateur radio. Something that you might not realise is that something like an X-ray is identical to shining a light of a torch through your palm. Only X-ray's are used for diagnostic purposes, we shine an X-ray light at your body and some gets through and some doesn't. We take a photo of that and use it to figure out what's under your skin. Back to radio. The same phenomena happen in radio. Buildings are good at stopping certain radio frequencies, in much the same way as they block light, but other frequencies barely get noticed, they shine right through. Similarly, the ionosphere around the earth can act as a reflection like the surface of a swimming pool for some frequencies, but not for other frequencies. Interestingly this changes throughout the day, depending on the sun and a whole range of other factors which I'm not getting into today. Finally, just like with light, you can turn up the brightness for different effects, you'll get further, but only if the conditions allow for it. To answer the original question about how far you can talk on amateur radio becomes much harder and now you know why. I'm Onno VK6FLAB

Richard Lighthouse is an American author and researcher. Lighthouse holds a Master of Science (M.Sc.) degree in Mechanical Engineering from Stanford University, and has previously worked for NASA. He regularly submits self-publications via Smashwords, Barnes and Noble and Amazon (for example). Lighthouse states that he is currently an executive of an energy company (Texas) and that his primary message is of an important scientific discovery: "Our universe literally blinks, off and on, more than 1 trillion cycles each second. (1.1 THz). The harmonics of this frequency can be used for Time travel, Faster than light travel, Travel between parallel universes, and Instant radio communication between galaxies." He makes the following assertion regarding (reality) as (we) may know it via his 2013 publication: "An Electrical Universe (EU) exists which forms the underlying structure for all physical universes, such as our own. In our terms, this Electrical Universe consists of zero dimensions – a single point. Electrical Universe consists of electrical charges of varying intensity (Volts) and Range (Amp*sec). Energy = Joules = Volts*Amp*sec - This EU exists independently from our physical universe, however, our physical universe “overlays” and is dependent upon the physics that reside within the EU. Electrical Universe is an analog-continuous system, whereas our physical universe is a discrete-digital system. (Our universe literally blinks off and on at a high frequency)." He has also been highly vocal regarding his opinion of the global financial system. With interests being broad in spectrum, he is quoted as saying the following regarding fraud and mis-representation on the London Stock Exchange: "Lloyd's Banking Group is probably the largest corporation in the world, with a global market capitalization exceeding $2.4 Quadrillion USD, according to Yahoo Finance. This company was formed in 1995, but based on its financials, it appears to be hiding trillions of dollars in assets. The total market capitalization of the stocks listed on the London Stock Exchange as LLD2, LLD5, LLD6, and LLD7 are quite large. In fact, it is larger than all other banks in the world combined. Think about that because it bears repeating – One bank in London has more assets and value than all other banks in the world combined. It is at least 100 times larger than the next largest bank – JPMorganChase." Additionally, he holds strong claims that the FBI and the CIA are "criminal organizations". In conjunction with the NSA, in the US, he claims that "everyone is being tracked with satellite microwave pulses" and that this is in violation of American civil rights. --- This episode is sponsored by · Anchor: The easiest way to make a podcast. https://anchor.fm/app Support this podcast: https://anchor.fm/iantrottier/support

This thesis reports on experimental demonstrations of a novel direct frequency-comb spectroscopic technique for the measurement of one- and two-photon excitation spectra. An optical-frequency-comb generator emits a multitude of highly coherent laser modes whose oscillation frequencies are evenly spaced and uniquely determined by only two measurable and adjustable radio-frequency parameters and the integer-valued mode number. Direct frequency-comb spectroscopy can traditionally be performed by scanning the comb lines of the frequency comb across the transitions of interest and measuring a signal that is proportional to the excitation by all comb lines in concert. Since the modes that contribute to the excitation cannot be singled out, transition frequencies can only be measured modulo the comb-line spacing with this scheme. The so arising limitations are overcome by the technique presented here, where the first frequency comb is spatially overlapped with a second frequency comb. Both combs of this so-called dual-comb setup are ideally identical except for having different carrier-envelope frequencies and slightly different repetition rates. The interference between the two combs leads to beat notes between adjacent comb lines, forming pairs (with one line from each comb) with an effectively modulated excitation amplitudes. Consequently the probability of excitation by any given comb-line pair is also modulated at the respective beat-note frequency. These beat-note frequencies are spaced by the repetition-rate difference and uniquely encode for individual comb-line pairs, thus enabling the identification of the comb lines causing an observed excitation. In a first demonstration, Doppler-limited one-photon excitation spectra of the transitions 5S_{1/2}-5P_{3/2} (at 384 Thz/780 nm), 5P_{3/2}-5D_{3/2}, and 5P_{3/2}-5D_{5/2} (both at 386 Thz/776 nm), and two-photon spectra of the 5S_{1/2}-5D_{5/2} (at 2x385 Thz/2x778 nm) transition, agreeing well with simulated spectra, are simultaneously measured for both stable Rb isotopes. Within an 18-s measurement time, a spectral range of more than 10 THz (20 nm) is covered at a signal-to-noise ratio (SNR) of up to 550. To my knowledge, this is the first demonstration of both dual-comb-based two-photon spectroscopy and fluorescence-based dual-comb spectroscopy. In a follow-up experiment probing the same sample and two-photon transitions, the Doppler-resolution limit is overcome by implementation of an anti-resonant ring configuration. Cancellation of the first-order Doppler effect makes it possible to resolve 33 hyperfine two-photon transitions. The highly resolved (1 MHz point spacing), narrow transition-linewidth (5 MHz), accurate (systematic uncertainty of ~340 kHz), high-SNR (10^4) spectra are shown to be consistent with basic simulation-based predictions. As the spectral span is, in principle, only limited by the bandwidths of the excitation sources, the acquisition of Doppler-free two-photon spectra spanning 10s of THz appears to be in reach. To my knowledge, this is the first demonstration of Doppler-free Fourier-transform spectroscopy. Lastly, the possibility of extending the technique's scope to applications in the field of biochemistry, such as two-photon microscopy, are explored. To that end, first high-speed, low-resolution (>>1 GHz) experiments are carried out identifying comb-stabilization requirements and measurement constraints due to the limited dynamic range of the presented highly multiplexed spectroscopic technique.

What use is an F-call? From DC to Daylight is a term that until I became an Amateur, I'd never heard of and since becoming licensed I've bumped into it more than a couple of times. Once you sit and think about it, the notion, from DC to Daylight makes perfect sense, but what does it mean? I'll start off with that I'm not talking about Cheap Therapy for your Inner Problem Child - the Rock band based in San Jose, California. So, DC, or Direct Current, as opposed to AC, or Alternating Current does not change frequency, that is, the positive and negative poles never swap over, so the frequency that they switch at is 0Hz or zero times per second. If you reverse the poles, the frequency at which you do that, say flick a switch once every second, the frequency is 1Hz. AC does it 50 or 60 times per second, or 50 or 60 Hz. As you keep increasing the frequency, you'll come past 160m, just below 2MHz, 80m around 7MHz, etc, onto 2m around 145MHz, 70cm and up to WiFi at 2.4GHz, then 5.8GHz, eventually, you'll get to a frequency of around 400 THz, where you'll bump into visible light where the wavelength is 750nm. So, DC is 0Hz, Daylight is 400 THz, so from DC to Daylight means from 0 Hz to 400 THz. Said in another way, DC to Daylight means "all frequencies". Of course, you could point out that there are frequencies above daylight, indeed there are. It's really a short hand term and as amateur radio terms go, it's one of the more explanatory ones. Now all you need is a DC to Daylight radio, and you'll be able to listen to everything that goes on anywhere - provided you have an appropriately tuned antenna - Hi Hi. I'm sure there are terms you've come across that make no sense. Have a look around, or better still, contact another Amateur and work it out together. The only silly question is the one you didn't ask. I'm Onno VK6FLAB

Molecular Aesthetics | Symposium Symposium at ZKM | Center for Art and Media, July 15 -17, 2011 in cooperation with DFG-Center for Functional Nanostructures (CFN) Karlsruhe Institute for Technology (KIT). Sonification - the study of the acoustic conversion of experimental data - covers various fields of application, such as monitoring and comprehension of physical phenomena, audio perception of the environment by visually impaired people, and musical composition. Among the various existing sonification techniques, the acoustic conversion of molecular vibrational spectra is well-suited for the exploration of microscopic structures. Non-audible oscillations naturally occur in molecules, at rates that are orders of magnitude faster than acoustic vibrations, in a frequency range extending from 30 GHz to 300 THz and can be recorded with spectrometers. Usual analyses of such spectra involve visual examinations, comparison of experimental data with spectral databases or computed spectra. An extended method for the acoustic and musical conversion of vibrational spectral data considers any piece of music as a combination of elementary waveforms. This method leads to molecular sounds, molecular scales and even molecular musical pieces. It translates into an audible signal the same physical phenomenon at different time scales. Its versatility allows the choice of the selected musical parameters and of the time scale descriptions of the corresponding waveforms, in order to obtain the most compelling musical results. /// Symposium im ZKM | Zentrum für Kunst und Medientechnologie, 15. -17. Juli 2011 In Kooperation mit dem DFG-Centrum für Funktionelle Nanostrukturen (CFN) des Karlsruhe Instituts für Technologie. Sonifikation - die Umwandlung experimenteller Daten in Klangereignisse - findet breite Anwendung, etwa in der Untersuchung und Überwachung physischer Phänomene, in akustischen Wahrnehmungshilfen für Sehbehinderte oder in der Musik. Die Transposition molekularer Schwingungsspektren in Tonsignale eignet sich ideal zur Erforschung mikroskopischer Strukturen. Moleküle oszillieren um ein Vielfaches schneller als Schallschwingungen in einem Frequenzbereich zwischen 30 GHz und 300 THz. Instrumente zur Aufzeichnung dieser Phänomene (Spektrometer) benutzen optische Komponenten und elektromagnetische Licht- und Infrarotstrahlung. Die Auswertung der höchst aufschlussreichen Schwingungsspektren erfolgt zumeist auf visuellem Weg oder durch den Vergleich mit gespeicherten oder rechnerisch erzeugten Spektren. Eine erweiterte Methode zur akustischen und musikalischen Darstellung molekularer Schwingungsfrequenzdaten definiert jedes beliebige Musikstück als Kombination elementarer Wellenformen. Die skizzierte Methode erzeugt molekulare Töne, molekulare Tonleitern und molekulare Musikstücke. Sie wird entlang verschiedener Zeitskalen in Tonsignale umgesetzt. Dieser flexible Ansatz ermöglicht die Auswahl der Ton- und Zeitparameter, die mit einer bestimmten Wellenform verbunden sind, und gewährleistet dadurch überzeugende musikalische Resultate.

The subject of this thesis is the muonic hydrogen (µp) Lamb shift experiment being performed at the Paul Scherrer Institute, Switzerland. Its goal is to measure the 2S-2P energy difference in µp atoms by laser spectroscopy and to deduce the proton root ­mean­ square (rms) charge radius with 10-3 precision, an order of magnitude better than presently known. This would make it possible to test bound-state quantum electrodynamics (QED) in hydrogen at the relative accuracy level of 10-7, and will lead to an improvement in the determination of the Rydberg constant by more than a factor of seven. Moreover it will represent a benchmark for QCD theories. The experiment is based on the measurement of the energy difference between the 2S(F=1) and 2P(F=2) levels in µp atoms to a precision of 30 ppm, using a pulsed laser tunable at wavelengths around 6 µm. Negative muons from a unique low energy muon beam are stopped at a rate of 70 s-1 in 0.6 hPa of hydrogen gas. Highly excited µp atoms are formed, and most of them promptly deexcite to the ground state within 100 ns. However, there is a roughly 1% probability that long­live µp(2S) atoms with a lifetime of 1.3 µs are formed. An incoming muon triggers a pulsed, multi­stage laser system which delivers 0.2 mJ per pulse at 6 µm with 55 s-1 repetition rate. It consists of two XeCl excimer lasers followed by dye lasers which pump an oscillator ­amplifier frequency ­controlled Ti:Sa laser. Its 6 ns long pulse at 708 nm is then frequency shifted to 6 µm via third Stokes production in a Raman cell filled with hydrogen. The laser pulse has a delay of about 1.5 µs with respect to the prompt muon cascade. If the laser is on resonance, it induces 2S-2P transitions. The subsequent deexcitation to the 1S state emits a 1.9 keV Lyman-alpha x ray which is detected by large area avalanche photo diodes. The resonance frequency, and hence the Lamb shift and the proton radius, are determined by measuring the intensity of these x rays as a function of the laser wavelength. A search for the 2S-2P resonance line was performed in November 2003 when a broad range of laser frequencies was scanned (49.7409 - 49.8757 THz), corresponding to proton radii between 0.844 and 0.905 fm. The result of the data analysis is that no significant 2S-2P resonance was observed. The negative result is with high probability due to the low statistics and not to an incorrect search region. The first part of this thesis reports on the present status of the Lamb shift theory in µp. Following, there is a detailed description of the apparatus and analysis of the data. An estimate of the present and future laser-­induced event rates are given, together with a study of the present and future background. In the Appendices are discussed: the energy levels in hydrogen, the proton radius definition, the relevance of this experiment, the 2S state population and lifetime, and the spectroscopic properties of the 2S-2P transition.

In the course of this work a new technique to measure the frequency of light has been developed, implemented and refined. For all time and frequency measurements the SI second defined by the cesium ground state hyperfine splitting near 9.2 GHz is the defined standard of reference. Therefore in precision optical frequency measurements optical frequencies on the order of several 100 THz – too fast to be counted with any electronics – have to be compared with radio frequencies on the order of a few GHz. The basic idea here is to measure dierences between optical frequencies with the help of frequency combs generated by the periodic pulse trains of femtosecond lasers. The output spectrum of such a laser consists of modes equally spaced by the repetition frequency of the pulses and forms a convenient ruler in frequency space. Extending this principle to the intervals between harmonics of the same optical frequency f, in the most simple case the interval between f and 2f, allows the absolute measurement of an optical frequency f = 2f − f. To bridge the interval between an optical frequency f and its second harmonic 2f a broad frequency comb with a width of several 100 THz is needed. This can be achieved with very short pulses (on the order of 5 fs) or with moderately short pulses on the order of a few 10 fs via self phase modulation in an optical fiber. Especially suited for such massive broadening are so called photonic crystal fibers. Here the light is guided in a very small core (1-2 µm) surrounded by air holes. This development culminates in the “single laser frequency chain” linking the radio frequency domain with the optical domain with the help of just one fs laser, a piece of fiber and some optics. Our optical frequency synthesizer can be used to measure not only one but almost any optical frequency with the same compact apparatus. Originally this project has been initiated to perform precision spectroscopy on the 1S- 2S transition in atomic hydrogen, a project with a long tradition in our group, and yielded what is thus far the most precise optical frequency measurement with a relative uncertainty of 1.8×10−14. Hydrogen as the most simple bound system served and still serves as an important cornerstone for tests of quantum physics, the measurement of the 1S Lamb shift represents one of the most accurate QED tests. Furthermore the Rydberg constant can be determined very precisely from optical frequency measurements in hydrogen. Soon it became obvious that this technique has a broad applicability. In this work transition frequencies in cesium, indium and molecular iodine have been measured. Besides that principle tests on this technique have been conducted. The direct comparison of two such frequency chains showed agreement on the level of 5 × 10−16. Further applications besides precision spectroscopy can be found in the time domain. There it is now possible with this technique to control the phase evolution of ultra short light pulses and perform optical waveform synthesis. As optical clock work for future all optical clocks a fs frequency chain transfers stability and accuracy from the optical to the rf domain.

With ultrashort pulses of less than 100 fs it is possible to excite coherently several vibrational modes of polyatomic molecules simultaneously. The femtosecond time resolution of the experiment allows the study of pronounced high-frequency beat phenomena up to 10 THz. The frequency difference between vibrational modes separated by more than 300 cm−1 may be determined with high precision.
