Le pulsar PSR J0453+1559 a été découvert en 2015, il est remarquable car il s'agit d'un système binaire rare composé de deux étoiles à neutrons. Ce qui a rendu PSR J0453+1559 encore plus surprenant, ce sont les masses des étoiles à neutrons. Alors que l'étoile première a une masse de 1,559 masses solaires, la seconde atteint seulement 1,174 M☉, ce qui en fait l'étoile à neutrons la plus petite connue, une masse si faible qu'elle est difficile à expliquer. Une équipe d'astrophysiciens ont effectué des simulations et arrivent à produire une étoile à neutrons de 1,192 masses solaires... on y est presque. L'étude est parue dans Physical Review Letters.

Okay, okay, wir beruhigen uns erst einmal. Nein, der Titel und das Thumbnail sind kein Clickbait – die Aussage stimmt zu 100 %. Dennoch sollten wir ganz ruhig bleiben. Was ist also wirklich passiert? Forscher in den USA haben etwas Unglaubliches geschafft: Sie haben den Quantenzustand eines Photons erfolgreich über ein Glasfaserkabel teleportiert – über eine Distanz von mehr als 30 Kilometern und das mitten in einem überlasteten Internetverkehr. Mit anderen Worten: Ein Teleport à la Star Trek inmitten der Datenflut unseres normalen Internets! Klingt nach einer technischen Meisterleistung, und das ist es auch. Doch was genau ist hier passiert, und was bedeutet das für unsere Zukunft? Bleib dran, denn die Antwort wird dich überraschen! Was ist Quanten-Teleportation wirklich?

Das Jahr 2024 war voller unglaublicher Entdeckungen in der Physik! In diesem Video findest du die Highlights: Von bahnbrechenden Experimenten in der Quantenmechanik bis hin zu neuen Erkenntnissen über die Struktur des Universums. Dieser Zusammenschnitt vereint die spannendsten Momente aus meinen Videos dieses Jahres. Lass uns gemeinsam auf die größten wissenschaftlichen Meilensteine zurückblicken!
Die allgemeine Relativitätstheorie von Albert Einstein gilt als Meilenstein der Physik, doch sie ist nicht ohne Lücken. Ein berühmtes Beispiel für diese Grenzen ist das Konzept der „Singularität“. Roger Penrose, Physik-Nobelpreisträger, zeigte, dass Singularitäten entstehen, wenn Materie unter ihrer eigenen Gravitation kollabiert. Stell dir vor: ein Punkt, unendlich dicht, unendlich gekrümmt – eine physikalische Absurdität. An Singularitäten scheitert unser Verständnis von Raum, Zeit und Materie. Sie werden buchstäblich ins Unendliche „zerquetscht“ und gleichzeitig ins Unendliche gedehnt, bis sie praktisch aufhören zu existieren. An diesem Punkt brechen alle bekannten Gesetze der Physik zusammen. Das klingt paradox, und genau das ist es. Die Gesetze der Physik, wie wir sie kennen, brechen dort vollständig zusammen. Was bedeutet das wenn wir das grob zusammenfassen müssten? Nun Unsere Fähigkeit, die Zukunft aus der Vergangenheit abzuleiten – ein Grundpfeiler der Wissenschaft – würde schlicht verschwinden. Die Wissenschaft – insbesondere die Physik – basiert auf einem Prinzip namens Determinismus. Dieses Prinzip besagt, dass der Zustand eines Systems zu einem bestimmten Zeitpunkt (z. B. die Position und Geschwindigkeit eines Objekts) die zukünftigen Zustände vollständig bestimmt, solange wir die zugrunde liegenden Gesetze der Physik kennen. Dies ermöglicht es uns, präzise Vorhersagen zu treffen, etwa über die Bewegung von Planeten oder das Verhalten von Teilchen. Doch an Singularitäten bricht dieses Prinzip zusammen. Der Grund ist, dass die physikalischen Gesetze, die normalerweise Raum, Zeit und Materie beschreiben, in einer Singularität nicht mehr anwendbar sind. Die Mathematik liefert „unendliche“ oder undefinierte Ergebnisse – wie etwa eine unendlich starke Krümmung der Raumzeit. Diese Werte sind physikalisch bedeutungslos. Das heißt, sie haben keinen Bezug zu unserer Realität. Wir können sie nicht begreifen, weil sie jenseits unseres Verständnisses und unserer Erfahrung liegen. LEGEN WIR ALSO LOS!

I wormhole, noti anche come ponti di Einstein-Rosen, sono teorizzati come tunnel che collegano due punti distanti nello spazio-tempo, permettendo un passaggio rapido tra essi. La spiegazione di come funziona un wormhole si basa sulla relatività generale di Einstein. Secondo alcuni documentari, i wormhole potrebbero teoricamente esistere e essere usati come macchine del tempo. Per costruire un wormhole stabile, sarebbe necessaria materia esotica con energia negativa, che impedirebbe al tunnel di collassare. Nei film come "Interstellar", i wormhole vengono rappresentati come passaggi praticabili per viaggi interstellari e temporali. Il concetto di wormhole come macchina del tempo implica che, manipolando uno degli ingressi con velocità relativistiche o posizionandolo in un forte campo gravitazionale, si potrebbe creare uno sfasamento temporale tra le due estremità. Questo permetterebbe di viaggiare nel tempo entrando in una estremità e uscendo nell'altra in un'epoca diversa. Tuttavia, sebbene l'idea sia affascinante, non esistono attualmente prove che i wormhole esistano nella realtà. Inoltre, costruire un wormhole con le tecnologie attuali è oltre le nostre capacità. La possibilità di viaggiare nel tempo attraverso i wormhole rimane quindi un affascinante tema di ricerca teorica e speculazione scientifica. FONTI • De-Chang Dai and Dejan Stojkovic.

The final parsec problem is a mystery that is yet to be answered by cosmology. On paper, supermassive black holes shouldn't merge. But yet they do. Why is it happening? What helps them slow down? Could it be dark matter? Looking for answers in this interview.

This week we talk about stainless steel, DARPA, and GNoME.We also discuss ceramics, DeepMind, and self-driving labs.Recommended Book: Drunk On All Your Strange New Words by Eddie RobsonTranscriptIn a recent episode, I talked a bit about the bronze and copper ages, and how reaching the level of technological know-how so that it's possible to heat metals so you can blend them with other metals, forge them into useful things, and generally work with them in a more fundamental way than is possible if you're simply chipping away at them, bending them with brute strength, and so on, grants you all sorts of additional powers that those cruder methods do not offer.Copper's a pretty basic material to work with, as metals go, in part because of its elemental properties, and in part because it appears in nature, on Earth, in its pure form, so it's not something our ancestors would have had to imagine from whole cloth—they could see it, work with it, and thus, had a pretty good sense of what it was and what it was capable of.Bronze, an alloy of copper—with some amount of tin mixed into the copper to make it more resilient and strong, and thus, useful for many things—was different in that it's not natural and doesn't occur unless we synthetically produce it.Iron is similar to copper in that it's natural, though it's also a lot stronger and thus harder to work with, lacking the metallurgical capacity to melt it down and reshape it in a liquified form, and steel is in this way a bit like bronze in that it's an alloy of iron—iron mixed with carbon—and variations on the theme, like stainless steels, have some amount of chromium blended in with the iron and carbon, alongside nickel, in some cases, which makes it even more complex, and thus essentially impossible to imagine if you're limited to what nature provides you, in terms of practicality, and thus, often at least, your conception of materials-related possibilities.So part of the challenge in attaining mastery over difference materials, including but not limited to metals, is discovering them and having access to the requisite natural resources, like iron and copper, in the first place, but then also, over time, learning that you can manipulate them in various ways, and then over time—often long, long stretches of time, generationally long periods of time in some cases—refining those methods of manipulation until it's possible to do so economically, but also, typically, at some kind of productive scale: allowing you to make enough of the material so you can churn out, for instance, armor and swords made out of it, or if we're talking about ceramic goods, stuff made of clay and silica and carbon, among other substances, scaling-up the process so you can produce more jugs and pots and urns, more food-preservation technologies and clay tablets for writing and bricks for building homes and other structures; and that's alongside the parallel process of simply learning how to capably work with these materials, once a sufficient volume of them becomes available.So while metal and clay are different sorts of substances, they're both materials that we use to make objects—we take basic, earth-derived stuff and reshape it into things that are useful to us in some way, whether that means as a weapon or means of manufacturing things, or as clothing, homes, or objects of beauty—artworks and such.Materials science is a field focused on the many facets of these types of resources, with some practitioners working with existing materials in order to better understand them, others sussing out various means of scaling-up production or iterating upon existing modes of production to make them more economical or sustainable, while still others aim to produce new materials of this kind: in some cases discovering existing-but-rare new materials, in the sense that we haven't discovered them, at least in the scientific sense, before, but often production, in this context, means combining different elements or other raw materials to create new materials.Just like our ancestors figured out how to make stronger, longer-lasting ceramic pots and how to make stainless steal out of iron alloyed with other substances, the contemporary version of that field often means working in laboratories and manufacturing hubs to investigate the blending-potential of various materials, and to then refine successful blends to see if the resulting whatever might have utility that can be exploited for some kind of productive purpose.What I'd like to talk about today is materials science, and how new innovations in the AI realm could push this field into an entirely new, and much faster-moving, paradigm.—As I mentioned in the intro, we've been doing what you might call materials science research and development since our earliest days of civilizational evolution, and almost certainly for quite a long while before that, too, because our deep, deep ancestors were all about making clever use of their environments and the materials in those environments, to get a leg-up over their competition.That said, modern materials science arose out of earlier, differentiated fields like metallurgy and ceramics engineering classes and laboratories, some of these educational and commercial hubs slammed together into unified, materials science departments in the 1960s when the US Advanced Research Projects Agency—the precursor to the Defense Advanced Research Projects Agency, or DARPA—started throwing money at universities with laboratories that seemed capable of helping the US economy, and by association the US military, gain broad-scale advantages over their international competition, by approaching materials research not just from the 30,000-foot, macro-scale view that pretty much every such department had approached such things from until this point, but also the micro-scale, atomic-level perspective: something more fields were beginning to attempt in the wake of WWII and the increasingly common realization that we've been missing out on a lot, not looking at things from the atomic level, up till that point, and that by leveraging advanced understandings about how these substances work from other fields, like physics, we could probably speed-up our development of new incredibly useful, omni-versatile materials, like steel or aluminum, dramatically.This would allow us to start our research with assumptions based on molecular and atomic science, rather than empirical, observational, comparably quite slow approaches, and that meant rather than waiting to observe and measure something interesting that happened, usually by doing a lot of fiddling around and hoping for good luck, over and over, day after day, we could instead very intentionally start cycling through all the potential blends that these other scientific understandings have told us are both possible and might be useful or interesting for various reasons.In the decades since, materials science has expanded still-further, encompassing new and ever-smaller scales, and new material types, like polymers—plastics, basically—that weren't really a thing when the unified field first, itself, became a thing.The impact this reorganization and refocus has had on the development of new materials cannot be overstated: among other things, innovations in this space has led to the development of artificial skin for burn victims, metal composites that have worked their way into all kinds of consumer products, making them more durable and lightweight, the production of medical hardware capable of performing magnetic resonance imaging and ultrasounds, the materials required to produce microchips of ever-smaller sizes, but with ever-denser capacities, nanotechnologies that have allowed for the shrinking of all sorts of components and devices, and the materials that have made the rapidly increasing efficiencies of solar panels possible, alongside the materials used in wind turbine blades and batteries with ever-embiggening capacities, safety features, and durabilities.The modern world, in essence, all modern technologies, and especially all digital goods, but also everything made out of any kind of metal or plastic that isn't raw iron or copper, both of which are increasingly rare in consumer goods, at least, was enabled by the field of materials science; lacking that mid-20th century development, it's a fair bet we would have been held back in pretty much every other scientific field, and thus, technological development, as well.That ubiquity and importance is part of why a recent announcement by Google's DeepMind division—an artificial intelligence lab under the larger company's brand-umbrella—has been getting so much attention.DeepMind has become well-known for its upending of chess, the game of Go, and more recently for creating a protein structure database that contains all its predictions for the 3D structures of folded proteins—showing how more than 200 million proteins will likely look based on their amino acid sequences, alone, solving what has long been called the "protein folding problem," which I spoke about at greater length in a previous episode, by the way.So we've got a database full of protein ingredients, amino acids, for all the proteins we've ever discovered, but just having those ingredients doesn't tell us what the finished proteins will look like in three-dimensions, once they've been built, because they fold up into a final shape after construction.Figuring out how finished, folded proteins made up of those ingredients we knew about, how they would actually look in real-life, has thus been a time-consuming, ponderous and expensive effort—all of science, our entire human civilization-wide scientific effort, was able to demonstrate the final, folded structures of something like 170,000 of the more than 200 million proteins we knew about, up till the early 2020s.That changed with DeepMind's AlphaFold program, which—using an AI technique called deep learning—was able to predict, imperfectly, but with enough accuracy to successfully predict single-mutation effects (what will happen if a protein has a single change to one of its amino acids, and how that will impact the final shape of the folder protein) all of those known proteins in our existing database.So predictions that are usable for many use-cases, and at what's been called a borderline miraculous or magical scale, applying this prediction model to every single protein we know about, as a species, at this point.That same lab has now applied a similar AI system to predicting and simulating how various materials will work together, if blended, and how their fusion, the product of that blending, will behave; what properties it will have.The company announced that they've developed a new deep learning system optimized for this purpose, called Graph Networks for Materials Exploration, or GNoME, and the initial outcome of running this tool was the discovery of about 2.2 million new crystalline structures, about 380,000 of which are stable enough to warrant further materials science investigation.Using current methods and extrapolating on the research currently being done and funding currently available to researchers in this space around the world, it's estimated that around 736 of these 380,000 new potential materials have already been discovered by researchers in experimental settings, and that this stockpile is equivalent to about 800 years'-worth of knowledge based on current levels of investment and output.So it would take about 800 years, at current levels of research in this space, to discover this many new potentially useful materials.All of which is wonderful, as—like with the folded protein predictions provided by AlphaFold—this new GNoME model gives materials scientists some focused areas to be looking at, making every experiment more likely to provide us with useable outcomes, rather than the shot-in-the-dark approach that's more common when looking into unfamiliar blends of materials.Many of these 380,000 potential new structures will likely be not useful for today's purposes, then, but this type of research rigs the dice so that each investigation is relatively more likely to yield something really valuable, which could prove to be hugely beneficial, especially since that catalog of potentially useful structures, like the protein fold catalog, has been published and made available to whomever wants it, for free.That's still a lot of work to do, of course, churning through all these potentially useful materials, which is why another development in this space—what's sometimes called self-driving labs—is also notable and potentially vital for the more-rapid development of materials science.Self-driving labs are basically lab spaces optimized for robotics that allow non-human, robot arms and other hardware, to perform the requisite, and often slogging, ponderous, tedious work of basic materials science experimentation, safely and continuously, around the clock.So just as you might automate a fast-food restaurant by telling some software what ingredients to combine and how to process them, in order to make a burger or some fries, keeping tabs on the temperature of everything and what's been mixed with what along the way, using specialized, automated equipment, you can also tell some software which materials to combine, and how, and have it keep track of everything's properties throughout the process using an array of sensors, and then some robot arms perhaps, or maybe just a big box with pipes and the ability to move stuff from here to there when prudent, will combine a slew of varied substances from a catalog of options, and then keep tabs on the resulting materials, tucking away examples for further, human exploration and confirmation if they're auto-tagged as being interesting for the sorts of properties we want to see, but otherwise maybe just categorizing them according to their properties, adding to the body of knowledge we already have for such things, and giving us a sort of materials reference library that we can tap into when we need a specific material with specific attributes, in the future.What this potentially does, then, is robotically automate the checking of the AI-generated catalog of potentially useful materials.The degree to which this could change the field cannot be overstated, as while that earlier, 1960s-era formalization of the field, combining earlier realms of inquiry was a big deal, changing everything, this next step could do the same, replacing humans—who are in many cases doing systematic, tedious work—with sleepless, emotionless, unkillable robots working from software-generated possibilities in order to provide us with a new menu of materials we might use, moving forward.This sort of development is especially important, arguably, because of all these new possibilities we now have available to try out: the number of possible combinations grows incredibly rapidly as the number of new materials and possible materials increases, and because there are only so many humans with the necessary skills and knowledge to do this kind of work, those human researchers have become kind of a bottleneck: good at what they do, but mostly tasked with responsibilities that can be automated, at least to some degree, their hands and eyes replaced with robot versions of the same, nothing lost in the transition and possibly a lot to be gained by swapping them out, including the optimization of those boring, predictable processes, and the ability to work more AI into the loop, those AI empowered to make more predictions and assumptions as new data from these experiments roll in, further speeding up the process of development and further optimizing the economics of such research, alongside the tangible fruits of that research.All of this, of course, is still bleeding-edge new, and there's a nonzero chance that some component of it ends up being not as useful or accurate as predicted or claimed, or that there will be some other glaring flaw that makes it not as desirable as it currently seems to be.And that might mean we have some wonderful new predictions to work from, but are stuck with the same plodding pace of working through them—or in contrast, maybe those predictions turn out to be not as great as advertised, and instead we have super-fast experimental robots in our arsenal, but a much smaller menu of potential materials to work through, limiting what we can do with those self-driving laboratories—at least in this field, at this moment.This is a maybe quite exciting moment for a field that touches essentially every other field, though, and if even a single-digit percentage of the purported possibilities of these new developments turn out to be accurate and manifestable, a lot of things could change very quickly, across many aspects of many industries, similar to the development of steel or plastics, but possibly even more rapidly deployed, and at a scale that the folks innovating those earlier wonder materials couldn't have dreamed of.Show

GW190521 est la détection gravitationnelle de la fusion de trous noirs les plus massifs à ce jour menant à un trou noir de 142 masses solaires. Plus de quatre ans après sa détection, des physiciens ont réanalysé les données et ils parviennent à isoler le signal de ringdown qui a suivi la fusion, le signal d'ondes gravitationnelles qui correspond au moment où le trou noir final reprend une forme parfaitement sphérique. C'est la toute première fois que l'on parvient à observer ce signal spécifique, qui nous permet de vérifier à nouveau la théorie de la relativité générale.

À mesure que l'univers évolue, la relativité générale et le modèle cosmologique standard qui en dérive prédisent que les grandes structures cosmiques doivent croître à un certain rythme : les régions denses comme les amas de galaxies, deviennent plus denses, tandis que les vides deviennent plus vide, à un certain rythme. Mais des chercheurs viennent de trouver que ce rythme de croissance est plus lent que ne le prévoit la théorie. Cela permet de résoudre des tensions existantes sur des paramètres du modèle standard, mais ça en crée une nouvelle et met le modèle standard à nouveau en difficulté.

Pour la première fois, des astrophysiciens ont analysé l'émission gamma de Jupiter. Cette recherche est importante car elle pourrait indiquer des traces de phénomènes très particuliers comme des annihilations de particules de matière noire qui se seraient accumulées dans la géante gazeuse. La détection des rayons gamma par le télescope Fermi-LAT montre la présence d'un signal à basse énergie mais qui n'est pas statistiquement significatif, menant donc à la détermination de limites drastiques sur la probabilité d'interaction de la particule de matière noire hypothétique avec les protons. Jupiter est ainsi devenue notre plus gros détecteur de matière noire et le plus sensible à basse énergie. L'étude est parue dans Physical Review Letters.

Depuis la découverte en 2007, grâce à des simulations numériques, que la fusion de trous noirs binaires ayant des spins différents peut conduire à des vitesses de recul gravitationnel importantes du trou noir résultant, une recherche de tels trous noirs est en cours. Pour déterminer quelle serait la plus grande vitesse de recul atteinte par un trou noir issu d'une fusion, deux physiciens ont effectué un grand nombre de simulations numériques en faisant varier les différents paramètres physiques en jeu. Ils trouvent une valeur maximale de vitesse qui défie l'entendement… Ils publient leur étude dans Physical Review Letters.

Ein Team aus Wissenschaftlern aus den USA haben in einer neuen Forschung gezeigt, dass sich Wellen, die aus Gruppen von Photonen bestehen, unter bestimmten Bedingungen sich schneller als das Licht bewegen können. Die meisten von uns sind mit dem Gesetzt vertraut, das die Geschwindigkeit begrenzt ist, mit der sich Informationen durch den leeren Raum bewegen kann: die Lichtgeschwindigkeit, die bei 300.000 Kilometern pro Sekunde ihren Höhepunkt erreicht. Während es unwahrscheinlich ist, dass Photonen selbst diese Geschwindigkeitsgrenze jemals überschreiten werden, gibt es Eigenschaften des Lichts, die nicht nach denselben Regeln spielen. Die Manipulation dieser Eigenschaften wird uns zwar nicht die Reise zu den Sternen erleichtern, aber sie könnten uns den Weg zu einer völlig neuen Klasse von Lasertechnologien ebnen. Schon seit einiger Zeit spielen die Forscher mit der Geschwindigkeitsgrenze von Lichtimpulsen, indem sie sie mit verschiedenen Materialien wie kalten Atomgasen, brechenden Kristallen und optischen Fasern beschleunigen oder sogar bis zum Stillstand verlangsamen. Dazu habe ich bereits ein Interview mit Prof. Dr. Florian Schreck geführt, er und sein Team haben in diesem Jahr unglaubliche Bahnbrechende Forschungsergebnisse im Bereich der Atomlaser Technik erreicht. Doch im vergangenen Jahr gelang es Forschern des Lawrence Livermore National Laboratory in Kalifornien und der University of Rochester in New York auf beeindruckende Weise, die Geschwindigkeit von Lichtwellen im Plasma auf etwa ein Zehntel der üblichen Vakuumgeschwindigkeit des Lichts bis zu mehr als 30 Prozent zu beschleunigen.

What do some amoebozoans and the urban planners of Tokyo have in common? And who is smarter? What even is intelligence? Find out by learning about Physarum polycephalum, a slime mold (aka "slimy guy") you could find on a walk in the woods. Scientist Kyle David talks about the lifestyle and weird features of P. polycephalum and how, even when it's meters long and wrapping itself around trees, it's really still only one single cell. We also talk about human vs. non-human intelligence, how this amoeba defies the human-created and often nebulous paradigms of "biological sex", and what we can learn from the formidable microbes around us.Dr. Kyle T. David, PhD is a postdoctoral fellow in the Rokas Lab at Vanderbilt University, who has studied the evolution of many organisms, from yeasts to frogs!

Kollisionen von Licht erzeugen Materie und Antimaterie aus reiner Energie. Studie demonstriert einen seit langem vorhergesagten Prozess zur direkten Erzeugung von Materie aus Licht – plus Beweise dafür, dass Magnetismus polarisierte Photonen entlang verschiedener Pfade im Vakuum biegen kann. Wissenschaftler, die Teilchenkollisionen am Relativistic Heavy Ion Collider (RHIC) untersuchen – haben nun endgültige Beweise für zwei physikalische Phänomene erbracht, die vor mehr als 80 Jahren vorhergesagt wurden. Diese Vorhersage gehört heute zu den sieben grundlegenden theoretischen Vorhersagen der Quantenelektrodynamik. Der Effekt, der auch als Breit-Wheller-Theorie bekannt ist, konnte aber bis heute nicht bestätigt werden. Der Hauptgrund liegt darin, dass für das Experiment so große Photonendichte benötigt wird, wie sie selbst die stärksten Laser derzeit nicht erzeugen können.

The Field Guide to Particle Physics : Season 3https://pasayten.org/the-field-guide-to-particle-physics©2022 The Pasayten Institute cc by-sa-4.0The definitive resource for all data in particle physics is the Particle Data Group: https://pdg.lbl.gov.The Pasayten Institute is on a mission to build and share physics knowledge, without barriers! Get in touch.The Positron ExcessSpace is not a safe place. Matter and energy take on a totally different form than is familiar from our planetary lifestyle. Radiation is everywhere, and with it we find high energy particles flying all over the place. One of the biggest challenges in a voyage to Mars is shielding the travelers from all that radiation. Our magnetosphere and atmosphere do an outstanding job of filtering out the most of the high energy particles flying at us from all directions.Many energetic particles come from the sun. Fast moving protons and electrons that boil off our friendly plasma ball get trapped in the van Allen belts of our earth's magnetic field. Way above the atmosphere, we can see them sometimes as the Aurora.Other energetic particles come to us from inside the Milky Way galaxy. Exploding stars, neutron stars and other monsterous astrophysical objects can shed or accelerate their own high energy particles. Often these particles have more energy than those put off by the sun, but it's the same story: A lot of protons, a few electrons, and also some heavier nuclei: like alpha particles. Much less often, we see cosmic rays made up of even bigger things, like the nuclei of Carbon, Silicon or even Iron!Some particles come from outside our galaxy. These can sometimes have outrageously high velocities, and are observed as miles-wide particle showers by large, ground based detector arrays. They aren't common. One of the biggest of these was observed by the Fly's Eye camera back in 1991. It had over 50 J of energy packed into a single particle - probably a proton. That's about the same kinetic energy as baseball being thrown around… in a single particle.Fast moving high energy particles - the ones flying in from outside our solar system - are typically called Cosmic Rays. A tiny fraction of these Cosmic Rays are actually antimatter. Antiprotons and positrons, specifically. Understanding where all these cosmic rays come from is an important scientific question in its own right, but understanding where the antimatter comes from - and how much of it there is - has been a truly fascinating question. Especially of late.Where does the cosmic antimatter come from?The ratio of matter to antimatter in Cosmic Rays is small, and varies with particle speed. Typical numbers are 1 or 2 antiprotons for every ten thousand protons. The ratio of positrons to electrons is higher, closer to a few parts in a hundred. One thing we haven't seen? Bigger antiparticles. No antideutrons or antialpha particles have been observed - at all - let alone bigger antinuclei. But of course, we see big nuclei in Cosmic Rays all the time.Because Cosmic Rays come from other parts of the galaxy - or even outside of it - these ratios are basically consistent with our typical assumption that all observed antimatter is secondary. It is created - in other words - through collisions or decay of so-called “normal” matter.Really fast Cosmic Rays occasionally interact with other particles in our galaxy: the tiny, sparse bits of gas and dust in the large voids between stars, sometimes called the interstellar medium. Those collisions often generate more particles, and just like in our own atmosphere, antiparticles are part of that collision debris.Just like the proton and the electron, to the best of our knowledge, the antiproton and the positron are stable particles. So unless they annihilate, these particles of antimatter just hang around. The collective effect of all these Cosmic Rays bounding around our galaxy is a very small - but measurable - population of antiprotons and positrons flying at us as secondary cosmic rays.If we were to assume that all antimatter is secondary - that is, if antiprotons and positrons are created only from collisions in the interstellar medium - we can use that assumption to calculate how much of it we expect to see. In these calculations, the number of antiprotons pretty much lines up expectations. While on the high side, the population of antiprotons in our galaxy essentially agrees with what you'd expect from collisions of other cosmic rays in the interstellar medium.While it is possible that antideutrons and antialpha particles can be also created in these collisions, they are rare. The expected number of them is currently far below current experimental sensitivity.Positrons are a different story. What's fascinating astroparticle physicists these days is that the number of positrons observed in Cosmic Rays is noticeably higher than we expect from these calculations. In particular, the number of positrons at higher energies is much bigger than we'd expect if they were only created in collisions, upwards of 10 percent or more!In short, we see too many positrons flying at us as Cosmic Rays and we don't know why!What we do know about Cosmic RaysEarth's atmosphere is much denser than interstellar space, so Cosmic Rays that make it to Earth typically collide dramatically with molecules in our upper atmosphere. With land-based detectors, we can see the resulting showers of particles down on Earth. We can calculate how much energy they had, but we can't exactly say what kind of particle they were.To assess the species of particle that's slamming into the Earth, we need to capture, identify and count them before they strike the atmosphere. We need, in other words, particle detectors on satellites.Older experiments like the Fermi Gamma Ray Telescope and the PAMELA detector were put in orbit around the earth on satellites. The current state of the art, the AMS-02 Cosmic Ray experiment is literally in a box attached to the side of the International Space Station.All these experiments agree: Cosmic Rays follow a somewhat predictable pattern. Most particles come equally from every direction in space, so as a population of particles, they're very likely diffused around the entire galaxy. The number of particles we see depends on their energy. Roughly speaking, the more energy a particle has, less common it is to see. But this trend is also true by particle species. In aggregate, simpler particles are also more common than complex ones. And of course, antimatter is far, far less common than matter.There are a few minor exceptions to these rules, and they have all been explained by various physical phenomena: like the distinction between lower energy cosmic rays from inside our galaxy to higher energy cosmic rays from outside our galaxy. Each of these minor bumps on the otherwise clean plots of counts of cosmic rays is a fascinating story in its own right. But today, we'll focus on one, massive, glaring irregularity:Again, the number of positrons observed as cosmic rays at higher energies is much higher than we'd expect.The Positron “Excess”Check out this plot from a 2019 publication by the AMS-02 Collaboration, Towards Understanding the Origin of Cosmic-Ray Positrons:Fig 4. from the above paper, https://doi.org/10.1103/PhysRevLett.122.041102Per the most recent AMS-02 data analysis, the spectrum of positrons in cosmic rays can be cleanly represented with a two-component model. The first component, valid at lower energies, is the usual, expected effect of interstellar media collision debris with higher energy cosmic rays. It peaks at about 5 to 10 GeV with a slightly long tail towards higher energies. The second component, valid at higher energies, appears to be associated with a different and stronger source of positrons, whose peak is closer to a few hundred GeV. This model for an as-yet-unknown source of positrons, is skewed in the other direction, with a longer tail towards lower energies, and a sharp cut-off estimated at about 800 GeV.Now, this two component model is just one interpretation of the data. An agnostic, best fit model. The essential point it captures, is the positrons in Cosmic Rays very likely come from multiple sources. The data associated to the second source term in the model is what we refer to as the “excess” of positrons.As noted in the aforementioned publication, there are few possible explanations for that excess. Pulsars - fast spinning husks of recently desceased stars - may well lose some of their rotational energy to radiation and the production of particle/antiparticle pairs. They could be a source for these positrons (see also this).Another, more intriguing explanation, is that the positrons are created as a byproduct of dark matter/antidark matter annihilation. [1] Dark Matter is a theoretical framework for explaining a vast array of astrophysical phenomena, which are all basically consistent with a new kind of stable or very long lived particle. Such a particle would not interact with light at all, hence the name, Dark Matter.Of course, we don't know if Dark Matter really is made up of particles, and if so, we don't know what those particles would be. They would represent new particle physics, a further extension of the Standard Model. Because many such models of new particle physics include particles that could act like Dark Matter, the positron excess serves as a consistency check or constraint on such models.If the annihilation of a new kind of Dark Matter particle were responsible for the excess of positrons [2], the AMS-02 data already highly constrains its properties. In particular, it has to be heavy, like around a TeV or more, and it has to decay through some intermediate state before producing any of those excess positrons. This scenario is at least qualitatively consistent with the fact that we haven't yet seen any evidence for Dark Matter at the LHC or in direct detectionexperiments [3]. In SummaryAntimatter is out there. It's coming in from outer space. Like the antimuons and positrons that appear in our atmosphere from collisions with these high energy particles, antiprotons and positrons are occasionally formed by tiny collisions all over our galaxy.The number of positrons we see are inconsistent with our understanding of how these secondary Cosmic Rays form. In certain energy ranges, we see far too many positrons. Something is definitely going on. Something we haven't yet accounted for.Something, perhaps... perhaps, like Dark Matter.Footnotes[1] Dr. Rebecca K. Leane, the author of that recent review on these kinds of Dark Matter Indirect Detection results, remarks that pulsars are currently favored to explain the excess. Of course, particle physicists remain excited until its ruled out! See also the following footnote.[2] It's worth pointing out that the as-yet statistically insignificant, slight overabundance of antiprotons could come from Dark Matter annihilation, too! Such antiprotons in cosmic rays also present constraints on Dark Matter annihilation models.[3] The usual disclaimer, with a twist! The DAMA/LIBRA collaboration has been claiming the observation of Dark Matter for years now, although it remains unconfirmed by any other experiment. Convention wisdom remains that Dark Matter has yet to be identified. To bolster that conventional wisdom, a recent, second-party analysis of the DAMA/LIBRA data has suggested their signal may result from a kind of systematic, statistical error.

Verblüffendes neues Multiversum-Szenario könnte eine seltsame Eigenschaft des Higgs-Bosons erklären und den Untergang des Multiversums beim Urknall. Als Forscher am Large Hadron Collider 2012 das schwer fassbare Higgs-Teilchen entdeckten, war dies ein Meilenstein für die Teilchenphysik. Es löste ein sehr heikles Problem, das seit langem bestand, indem es das Standardmodell der Teilchenphysik bestätigte und dessen Gültigkeit ermöglichte. Doch wie es bei neuen Entdeckungen oft der Fall ist, wurden zwar einige Fragen eindeutig beantwortet, aber andere tauchten auf. Im Falle des Higgs-Bosons ist eine dieser Fragen seine Masse. Nach den Vorhersagen die wir haben, müsste das Teilchen etwa dreimal so schwer sein wie die Masse die es eigentlich besitzt.

Gravitationswellen vom Beginn des Universums entdeckt? Zwei faszinierende Signale, die in einem kleinen Gravitationswellendetektor entdeckt wurden, könnten auf alle möglichen exotischen Phänomene hindeuten - von neuer Physik über dunkle Materie, die mit schwarzen Löchern interagiert, bis hin zu Schwingungen aus aus dem Anfang des Universums. Lange bevor diese riesigen Observatorien gebaut wurden, vermuteten Wissenschaftler, dass Gravitationswellen dieser Größenordnung existieren, weil sie wussten, dass Schwarze Löcher und Neutronensterne manchmal zusammenstoßen sollten, so Michael Tobar, Physiker an der University of Western Australia in Perth.

I've got a treat for you today. Today's author's are Gourab Ghoshal and Petter Holme, who are here to talk about a classic paper. A paper they co-authored and published in PRL in 2006. The paper has a fantastic title, which is basically also a mini abstract. It is called “Dynamics of Networking Agents Competing for High Centrality and Low Degree” (1). In the podcast we get into it!Gourab is at at Rochester University, where he is an Associate Professor of Physics and Astronomy with joint appointments at the departments of Computer Science and Mathematics. He works in the field of Complex Systems. His research interests are in the theory and applications of Complex Networks as well as Non-equilibrium Statistical Physics, Game theory, Econophysics, Dynamical Systems and the Origins of Life.Petter is Swedish scientist living and working in Japan, where he is a Specially Appointed Professor at the Institute of Innovative Research at the Tokyo Institute of Technology. His research focuses on large-scale structures in society, technology and biology; mostly trying to understand them as networks.# Timestamps[0:00:00] Intro and friendly banter[0:04:00] Gourab's dream of becoming Richard Feynman[0:10:10] Petter becomes a network scientist by accident[0:17:45] We dive into the paper!

Deciphering the patterns of nature is something that has occupied curious minds for countless generations, from swarms of bugs to the flight of birds to the movement of your bodies own cells. Prof Andrea Cavagna of the Institute for Complex Systems leads a research group bringing together the worlds theoretical physics and experimental biology, building mathematical models of natural systems and uncovering the universal laws that underly the organisation structure of life.Read the original paper on swarm behaviours: https://doi.org/10.1103/PhysRevLett.123.268001

Raindrops on roses and whiskers on kittensBacteria in blenders and bird poop confusionDoggies that drool when a little bell ringsThese are a few of our favorite things . . . More specifically, these are a few of Jocelyn and Bradley’s all-time favorite experiments in the history of science! This week, the hosts consider the role of experiment in the scientific process and the qualities that make an experiment especially significant or compelling. They highlight several “classic” experiments in physics, cosmology, genetics, molecular biology, and psychology, and they discuss how these experiments tested the limits of human ingenuity to crystallize key concepts and chart new directions for scientific research.

Why A Medium-Sized Black Hole Is Surprising Physicists If you’re looking for a black hole, they normally come in two sizes. There’s the basic model, in which a large, dying star collapses in on itself, and the gravity of its core pulls in other matter. Then there are the supermassive black holes, millions of times the mass of our sun, that tend to be found at the center of a galaxy. But recently researchers reported that they had evidence for two colliding black holes that created a surprising offspring. Their collision formed a middle-weight black hole, around 142 times the mass of our sun. Daniel Holz, a member of the LIGO team that spotted the collision, and a professor of astronomy and astrophysics at the University of Chicago, joins Ira to talk about what the observation means for theories of how black holes form and grow. Against Impossible Odds, The Warsaw Ghetto Stopped A Typhus Outbreak This year marks the 80th anniversary of the establishment of the Warsaw Ghetto in November of 1940. The Nazis purposefully tried to starve to death almost half a million Jews, who were kept with little food and water in a space about the size of Central Park. Theoretical mathematician Lewi Stone of Tel Aviv University has been studying a concurrent public health crisis that happened in the Warsaw Ghetto: a Typhus outbreak. The infectious disease is spread by lice, and can be deadly. Typhus ran rampant in the Warsaw Ghetto for the better part of 1941. But when the winter rolled around, the expected second wave never came. Researchers have found evidence that public health measures enacted under these impossible circumstances—think public education and social distancing—actually worked. Stone talks to SciFri producer Kathleen Davis about this research, and potential takeaways for 2020’s public health crisis. It’s Still A Wild, Wonderful World The table of contents for poet Aimee Nezhukumatathil’s new book of essays reads like a list of evolution’s most fantastic products. The comb jelly, which pulses with rainbow bioluminescence. The smiling-faced axolotl, which can regrow lost limbs and is a star of biology research labs, but is considered critically endangered in the wild. The human-sized corpse flower, which blooms for a mere 24 hours, smelling of dead flesh. It’s also a deeply personal book: Nezhukumatathil says the screaming pink of dragonfruit signals “summertime, pop music, sunglasses balanced on the top of my head, weather too warm for socks.” A firefly’s spark might send her back to her grandmother’s backyard, or “to splashing in an ice-cold creek bed, with our jeans rolled up to our knees, until we shudder and gasp, our toes fully wrinkled.” Even the horizontal eye of an octopus becomes a “door that judges us,” as the oceans become increasingly difficult to inhabit, thanks to humans’ ravages. Science Friday’s Christie Taylor talks to Nezhukumatathil about her experiences in natural wonder, and why in a world of changing climate, rising seas, and burning forests, she finds it important to share her joy in learning about the creatures we share the planet with.
* How Did Radioactive Decay Start in Earth's Crust? (Re-run during recovery from a minor accident while Bob was out boating. "See you guys, Lord-willing, next week!") Real Science Radio co-hosts Bob Enyart and Fred Williams describe Walt Brown's Hydroplate Theory from his book, In the Beginning, and Dr. Brown's discovery of the origin of Earth's radioactivity. Ways to learn about the origin of Earth's radioactivity: - Listen to today's program (above) - Read this written show page - Read Bob's brief 2019 RMCF articles Part 1 & Part 2 - Read Walt's theory right here at hpt.rsr.org - See this visually just below in Bryan Nickel's video tutorial - Read Walt's theory beginning on page 380 of the PDF of ITB 9th Edition. Consider: - God created a paradise for mankind so no radioactivity would have existed on the original Earth because radioactive decay can cause birth defects, disease, and death with lowered lifespans. - For ex., uranium formed on Earth, as evidence by its worldwide ratio (see below) - The fourth state of matter, beyond solid, liquid, and gas, is plasma (lightning, neon lights, etc.) which is like a gas but with the electrons stripped away.- By the piezoelectric effect, pressure on quartz produces an electric voltage and the granite in the Earth's crust is more than one-fourth quartz. - Z-pinched electrical pulses produce nuclear combustion by stripping away electrons and then squeezing together nuclei producing radioactive and other elements. - Decay rates speed up by a billion times or more when half lives are measured for atoms stripped of their electrons; for example when ionized the 41-billion year half life of rhenium's beta decay speeds up to 33 years.- Atmospheric lightning produces new isotopes (most of which decay within minutes). 2017 Update: Nature reports that lightning storms "trigger atmospheric photonuclear reactions" that produce isotopes. [In 2010 Dr. Brown published his Radioactivity theory including references to little noticed research showing that atmospheric lightning produces radioisotopes (and also explains the Oklo Natural "Reactor").] 2017 Science Headlines: Lightning produces radioisotopes. (See ITB since 2010.) - Earthquake Lights: Earthquakes produce piezoelectric lightning flashes in the ground and also, coming out of the ground. (See also rsr.org/eql.) 2017 Update: Twitter video of this phenomenon during Mexico's deadly magnitude 8.1 quake. [Thanks to RSR London listener Remy for the heads up.] 2016 Update: Video of earthquake lights surface, this time after New Zealand's magnitude 7.8 quake epicentered between Christchurch and Wellington. 2014 Update: A paper in the journal Seismological Research Letters is reported on in USA Today's Scientists find records of rare 'earthquake lights'. 2013 Update: This may be the phenomena causing the apparent pre-quake disturbances in the ionosphere that led scientists to consider a possible earthquake warning system, as reported in 2008 by BBC News, and pursued by the U.K. and Russia in 2011 and generating continued interest and research in 2013 in a European Geophysical Union conference presentation, and here with RSR's 2014 interview with QuakeFinder. - The journal Nature reports that an average earthquake produces hundreds of millions of volts. - During the upheaval of the global flood pressure in the crust produced enormous voltages that produced plasma surges in the crust. - Those voltages smashed together the nuclei of atoms to create, in the crust, radioactive elements and massive, instantaneous apparent radioactive decay.- Missing uniform distribution of earth's radioactivity: From our RSR debate with theoretical physicist (emphasis on the theoretical), Lawrence Krauss... The theory of chemical evolution claims that all of our radioactive elements were created in the explosion of stars, but that would predict a relatively uniform distribution on Earth, at least throughout the crust, and possibly the mantle too. However, in an otherwise contentious interview, Krauss agreed with Enyart's statement on air that 90% of Earth's radioactivity (uranium, thorium, potassium-40, etc.) is located in the continental crust, and Krauss added, a mystery for him, that it tends to concentrate around granite! That is, that 90% is not in the mantle nor in the enormous amount of the crust which lies under the oceans, but our planet's radioactivity is concentrated in 1/3rd of 1% of the Earth's mass, in the continental crust. (Further, the release of it's heat has not yet reached a steady state.) Krauss offered a partial explanation: that uranium was originally evenly distributed throughout (an alleged) molten earth but being a large atom, it floated toward the surface. This the bias of this physicist led him to forget, apparently, that it is density, and not size, that causes things to float. Even denser than gold, uranium is one of the most dense elements (excluding atheists and other manmade phenomena). Further, for argument's sake, that would only explain the relative absence of radioactivity deep in the Earth, but would not explain uranium's distancing itself from the mantle and from the oceanic crust, nor its affinity for the continents and even, of all things, for granite. Further, under Krauss' belief in the widespread falsehood that the planet was once molten, if so, then the gold in the crust should have sunk to the core! The creationists, on the other hand, have a theory based on observational science as to why radioactivity is concentrated around granite. - Absurd consistency of uranium isotopes IF formed in space: Consider this from Walt Brown's Origin of Earth's Radioactivity chapter: The isotopes of each chemical element have almost constant ratios with each other. ... Why is the ratio of 235U to 238U in uranium ore deposits so constant almost everywhere on Earth? One very precise study showed that the ratio is 0.0072842, with a standard deviation of only 0.000017. [There's less than one U235 atom, with its 700M year half-life, for every hundred U238s, with their 4.5B year half-lives.] Obviously, the more time that elapses between the formation of the various isotopes (such as 235U and 238U) and the farther they are transported to their current resting places, the more varied those ratios should be. The belief that these isotopes formed in a supernova explosion millions of light-years away and billions of years before the Earth formed and somehow collected in small ore bodies in a fixed ratio is absurd. Powerful explosions would have separated the lighter isotopes from the heavier isotopes. Some radioisotopes simultaneously produce two or more daughters. When that happens, the daughters have very precise ratios to each other, called branching ratios or branching fractions. Uranium isotopes are an example, because they are daughter products of some even heavier element. Recall that the Proton-21 Laboratory has produced superheavy elements that instantly decayed. Also, the global flux of neutrons during the flood provided nuclei with enough neutrons to reach their maximum stability. Therefore, isotope ratios for a given element are fixed. Had the flux of neutrons originated in outer space, we would not see these constant ratios worldwide. Because these neutrons originated at many specific points in the globe-encircling crust, these fixed ratios are global. - Waltbrownium, the IUPAC, and the Nobel Prize in Physics: The element that decayed into daughter products U-235 and U-238 is the naturally occurring though now-extinct waltbrownium. Symbol Wb. Atomic number (Z) 184. Atomic weight of > 473.07. 184 protons. > 289 neutrons. Solid at Earth's crustal temperatures and pressures. Half-life perhaps ~10 ns. Waltbrownium is the heaviest chemical element discovered (though indirectly) and therefore atop the post-Actinoid series. Wb is not [yet] an IUPAC officially named element but has been preliminarily named, here, by RSR. The identification of this element should earn its discoverer a Nobel Prize in Physics after he identified the evidence for its existence and the experimental evidence for its formation. The uniform uranium ratio provides the evidence to confirm that waltbrownium existed on the Earth. (This evidence provides as much, or even more, confirmation as neutrinos provide for solar fusion.)

* How Did Radioactive Decay Start in Earth's Crust? (Re-run during recovery from a minor accident while Bob was out boating. "See you guys, Lord-willing, next week!") Real Science Radio co-hosts Bob Enyart and Fred Williams describe Walt Brown's Hydroplate Theory from his book, In the Beginning, and Dr. Brown's discovery of the origin of Earth's radioactivity. Ways to learn about the origin of Earth's radioactivity: - Listen to today's program (above) - Read this written show page - Read Bob's brief 2019 RMCF articles Part 1 & Part 2 - Read Walt's theory right here at hpt.rsr.org - See this visually just below in Bryan Nickel's video tutorial - Read Walt's theory beginning on page 380 of the PDF of ITB 9th Edition. Consider: - God created a paradise for mankind so no radioactivity would have existed on the original Earth because radioactive decay can cause birth defects, disease, and death with lowered lifespans. - For ex., uranium formed on Earth, as evidence by its worldwide ratio (see below) - The fourth state of matter, beyond solid, liquid, and gas, is plasma (lightning, neon lights, etc.) which is like a gas but with the electrons stripped away.- By the piezoelectric effect, pressure on quartz produces an electric voltage and the granite in the Earth's crust is more than one-fourth quartz. - Z-pinched electrical pulses produce nuclear combustion by stripping away electrons and then squeezing together nuclei producing radioactive and other elements. - Decay rates speed up by a billion times or more when half lives are measured for atoms stripped of their electrons; for example when ionized the 41-billion year half life of rhenium's beta decay speeds up to 33 years.- Atmospheric lightning produces new isotopes (most of which decay within minutes). 2017 Update: Nature reports that lightning storms "trigger atmospheric photonuclear reactions" that produce isotopes. [In 2010 Dr. Brown published his Radioactivity theory including references to little noticed research showing that atmospheric lightning produces radioisotopes (and also explains the Oklo Natural "Reactor").] 2017 Science Headlines: Lightning produces radioisotopes. (See ITB since 2010.) - Earthquake Lights: Earthquakes produce piezoelectric lightning flashes in the ground and also, coming out of the ground. (See also rsr.org/eql.) 2017 Update: Twitter video of this phenomenon during Mexico's deadly magnitude 8.1 quake. [Thanks to RSR London listener Remy for the heads up.] 2016 Update: Video of earthquake lights surface, this time after New Zealand's magnitude 7.8 quake epicentered between Christchurch and Wellington. 2014 Update: A paper in the journal Seismological Research Letters is reported on in USA Today's Scientists find records of rare 'earthquake lights'. 2013 Update: This may be the phenomena causing the apparent pre-quake disturbances in the ionosphere that led scientists to consider a possible earthquake warning system, as reported in 2008 by BBC News, and pursued by the U.K. and Russia in 2011 and generating continued interest and research in 2013 in a European Geophysical Union conference presentation, and here with RSR's 2014 interview with QuakeFinder. - The journal Nature reports that an average earthquake produces hundreds of millions of volts. - During the upheaval of the global flood pressure in the crust produced enormous voltages that produced plasma surges in the crust. - Those voltages smashed together the nuclei of atoms to create, in the crust, radioactive elements and massive, instantaneous apparent radioactive decay.- Missing uniform distribution of earth's radioactivity: From our RSR debate with theoretical physicist (emphasis on the theoretical), Lawrence Krauss...

Doctor Who has finished another season with the biggest bombshell in nearly 60 years of stories. What does this mean? Why is it happening? And why does it taste like caramel and marzipan? Nobody except the leakers could have known what was going to happen this time, and it's more controversial than politics. Doctor Who has time traveled back to the 80s to pick up some plot ideas from the Dark Times between the cancellation and revival.Hello Ducky, my old friend. I've come to talk with you again.

According to local media, the incident was due to "a quarrel for a property" with the attacker. He died at the age of 55.1 March 2020 – Ghibli art exhibition in Japan – https://www.animenewsnetwork.com/interest/2020-03-01/preview-ghibli-theme-park-displays-one-last-time-before-its-2022-opening/.156989The Aichi Prefectural Museum of Art will hold an exhibit called "The Great Ghibli Exhibit ~Two More Years Until the Ghibli Park's Opening~". It will include display items destined for the upcoming Ghibli Park from June 25 to September 16. The exhibit will be the last preview of the theme park's contents before they move into the park's Ghibli no Daisōko Area (Giant Ghibli Storehouse) in two years. The latest version of the exhibit will also add previously unreleased materials. Entry to the exhibit will cost 1,600 yen (US$14) for a same-day adult ticket, or 1,400 yen (US$13) for a pre-booked ticket.Remembrances2 March 1729 – Francesco Bianchini - https://en.wikipedia.org/wiki/Francesco_BianchiniItalian philosopher and scientist. He worked for the curia of three popes, including being camiere d'honore of Clement XI, and secretary of the commission for the reform of the calendar, working on the method to calculate the astronomically correct date for Easter in a given year. His deduction of a rotational period of Venus was based on the observation of its surface using a 2.6" (66mm) 100-foot focal length aerial telescope. Today, we know that this is impossible, because of the thick cloud cover on this planet. He also worked on the parallax of Venus, and he measured the precession of the Earth's rotational axis. As part of his efforts to improve the accuracy of the calendar, Bianchini was commissioned by Clement XI to construct an important meridian line in the Basilica of Santa Maria degli Angeli e dei Martiri (the Basilica of Saint Mary of the Angels and the Martyrs) in Rome, a device for calculating the position of the sun and stars. Craters on Mars and the Moon are named in his honour. He died at the age of 67 in Rome.2 March 1930 – D.H Lawrence - https://en.wikipedia.org/wiki/D._H._LawrenceEnglish writer and poet. His collected works represent, among other things, an extended reflection upon the dehumanising effects of modernity and industrialisation. Some of the issues Lawrence explores are sexuality, emotional health, vitality, spontaneity, and instinct. Lawrence's opinions earned him many enemies and he endured official persecution, censorship, and misrepresentation of his creative work throughout the second half of his life, much of which he spent in a voluntary exile he called his "savage pilgrimage". Lawrence is best known for his novelsSons and Lovers, The Rainbow, Women in Love and Lady Chatterley's Lover. In these books, Lawrence explores the possibilities for life within an industrial setting. Lawrence is concerned with the nature of relationships that can be had within such a setting. Though often classed as a realist, Lawrence in fact uses his characters to give form to his personal philosophy. His depiction of sexuality, though seen as shocking when his work was first published in the early 20th century, has its roots in this highly personal way of thinking and being. He died from tuberculosis at the age of 44 in Vence.2 March 1944 – Ida Maclean - https://en.wikipedia.org/wiki/Ida_MacleanEnglish biochemist and the first woman admitted to the London Chemical Society. Between 1920 and 1941 Maclean published in the Biochemical Journal approximately thirty papers, many in collaboration, on her particular interests, namely the role of fatty acids in animals and the synthesis of fats from carbohydrates. She came to be regarded as an authority on biochemistry, and her 1943 monograph The Metabolism of Fat was the first published of Methuen's series Monographs on Biochemical Subjects. She died at the age of 66 in London.2 March 1962 – Charles Jean De La Vallee Poussin - https://en.wikipedia.org/wiki/Charles_Jean_de_la_Vall%C3%A9e_PoussinCharles-Jean Étienne Gustave Nicolas, baron de la Vallée Poussin, Belgianmathematician. He is best known for proving the prime number theorem. The king of Belgium ennobled him with the title of baron. Although his first mathematical interests were in analysis, he became suddenly famous as he proved the prime number theorem independently of his coeval Jacques Hadamard in 1896. He also published a counterexample to Alfred Kempe's false proof of the four color theorem. The Poussin graph, the graph he used for this counterexample, is named after him. He died at the age of 95 in Watermael-Boitsfort, Brussels.Famous Birthdays2 March 1545 – Sir Thomas Bodley – https://en.wikipedia.org/wiki/Thomas_BodleyEnglish diplomat and scholar who founded the Bodleian Library in Oxford. In 1444, the existing university library was augmented by a gift of some 300 manuscripts from Humphrey, Duke of Gloucester, the youngest son of Henry IV; this prompted the university to build a new library above the Divinity School which was at that time under construction. However, during the Reformation of the 1550s, the library had been stripped and abandoned, remaining virtually untouched until the return of Bodley in 1598. The library was later named the Bodleian Library in his honour. He determined, he said, "to take his farewell of state employments and to set up his staff at the library door in Oxford." In 1598 his offer to restore the old library was accepted by the university. Bodley began his book collection effort in 1600, using the site of the former library above the Divinity School, which was in near ruin. Although Bodley lived over 400 years ago, modern libraries benefit from some of his ideas and practices. One important idea that Bodley implemented was the creation of a "Benefactors' Book" in 1602, which was bound and put on display in the library in 1604. While he did have funding through the wealth of his wife, Ann Ball, and the inheritance he received from his father, Bodley still needed gifts from his affluent friends and colleagues to build his library collection. Although not a completely original idea (as encouragement in 1412 the university chaplain was ordered to say mass for benefactors), Bodley recognized that having the contributor's name on permanent display was also inspiring. He was born in the city of Exeter in Devon.2 March 1886 – Willis H. O’Brien – https://en.wikipedia.org/wiki/Willis_H._O%27BrienAmerican motion picture special effects and stop-motion animation pioneer, who according to ASIFA-Hollywood "was responsible for some of the best-known images in cinema history," and is best remembered for his work on The Lost World (1925), King Kong (1933) and Mighty Joe Young (1949), for which he won the 1950 Academy Award for Best Visual Effects. The Academy of Motion Picture Arts and Sciences (AMPAS) proposed giving O'Brien an Oscar for his technical effects on King Kong but Willis insisted that each of his crew receive an Oscar statue also, which the AMPAS refused to do, so O'Brien refused to accept the Oscar award for himself. He was born in Oakland California.2 March 1902 – Edward Condon - https://en.wikipedia.org/wiki/Edward_CondonDistinguished American nuclear physicist, a pioneer in quantum mechanics, and a participant in the development of radar and nuclear weapons during World War II as part of the Manhattan Project. The Franck–Condon principle and the Slater–Condon rules are co-named after him. During the McCarthy period, when efforts were being made to root out communist sympathizers in the United States, Edward Condon was a target of the House Un-American Activities Committee on the grounds that he was a 'follower' of a 'new revolutionary movement', quantum mechanics; Condon defended himself with a famous commitment to physics and science. Condon became widely known in 1968 as principal author of the Condon Report, an official review funded by theUnited States Air Force that concluded that unidentified flying objects (UFOs) have prosaic explanations. The lunar crater Condon is named for him. He was born in Alamogordo, New Mexico.2 March 1904 – Dr. Seuss – https://en.wikipedia.org/wiki/Dr._SeussTheodor Seuss "Ted" Geisel, American children's author, political cartoonist, illustrator, poet, animator, screenwriter, and filmmaker. He is known for his work writing and illustrating more than 60 books under the pen name Dr. Seuss. Geisel adopted the name "Dr. Seuss" as an undergraduate at Dartmouth College and as a graduate student at Lincoln College, Oxford. He published his first children's book And to Think That I Saw It on Mulberry Street in 1937. During World War II, he took a brief hiatus from children's literature to illustrate political cartoons, and he also worked in the animation and film department of the United States Army where he wrote, produced or animated many productions – both live-action and animated – including Design for Death, which later won the 1947 Academy Award for Best Documentary Feature. After the war, Geisel returned to writing children's books, writing classics like If I Ran the Zoo (1950), Horton Hears a Who! (1955), If I Ran the Circus (1956), The Cat in the Hat (1957), How the Grinch Stole Christmas! (1957), and Green Eggs and Ham (1960). He published over 60 books during his career, which have spawned numerous adaptations, including 11 television specials, five feature films, a Broadway musical, and four television series. He was born in Springfield, Massachusetts.Events of Interest2 March 1949 – Captain James Gallagher lands his B-50 Superfortress Lucky Lady II in Fort Worth, Texas after completing the first non-stop around-the-world airplane flight in 94 hours and one minute - https://www.wired.com/2010/03/0302b50-nonstop-circumnavigation/The flight covered 23,452 miles, averaging a ground speed of 249 miles per hour. The modified bomber required air-to-air refueling four times as it flew ever eastward. The airplane was an updated version of the B-29 that had fought in World War II and was close to being obsolete by 1949. Refueling while flying was the biggest challenge of the flight. Though commonplace today, the technique was not widely used at the time. The Lucky Lady II was refueled from its close relative, the tanker version KB-29. Four pairs of KB-29s based in the Azores, Saudi Arabia, the Philippines and Hawaii were used as airborne gas stations. The Lucky Lady II was actually the second aircraft set up for the around-the-world flight. The first B-50, Global Queen, experienced engine problems after taking off Feb. 25 and landed in the Azores. The jet-powered B-52 bomber erased the Lucky Lady II's record in 1957 with a circumnavigation lasting just 45 hours, 19 minutes. Another B-52 lowered the record in 1980 to 42 hours, 23 minutes. The record still stands today.2 March 1972 – The Pioneer 10 space probe is launched from Cape Canaveral,Florida with a mission to explore the outer planets - https://www.history.com/this-day-in-history/pioneer-10-launched-to-jupiterPioneer 10, the world’s first outer-planetary probe, is launched from Cape Canaveral, Florida, on a mission to Jupiter, the solar system’s largest planet. In December 1973, after successfully negotiating the asteroid belt and 620 million miles, Pioneer 10 reached Jupiter and sent back to Earth the first close-up images of the spectacular gas giant. In June 1983, the NASA spacecraft left the solar system and the next day radioed back the first scientific data on interstellar space. NASA officially ended the Pioneer 10 project on March 31, 1997, with the spacecraft having traveled a distance of some six billion miles.2 March 1978 – Grave robbers steal Charlie Chaplin’s body - https://www.history.com/this-day-in-history/grave-robbers-steal-charlie-chaplins-bodyIn one of history’s most famous cases of body-snatching, two men steal the corpse of the revered film actor Sir Charles Chaplin from a cemetery in the Swiss village of Corsier-sur-Vevey, located in the hills above Lake Geneva, near Lausanne, Switzerland. After Chaplin’s widow, Oona, received a ransom demand of some $600,000, police began monitoring her phone and watching 200 phone kiosks in the region. Oona had refused to pay the ransom, saying that her husband would have thought the demand “ridiculous.” The callers later made threats against her two youngest children. After a five-week investigation, police arrested two auto mechanics–Roman Wardas, of Poland, and Gantscho Ganev, of Bulgaria–who on May 17 led them to Chaplin’s body, which they had buried in a cornfield about one mile from the Chaplin family’s home in Corsier. That December, Wardas and Ganev were convicted of grave robbing and attempted extortion. Political refugees from Eastern Europe, Wardas and Ganev apparently stole Chaplin’s body in an attempt to solve their financial difficulties. Wardas, identified as the mastermind of the plot, was sentenced to four-and-a-half years of hard labor. As he told it, he was inspired by a similar crime that he had read about in an ItalianFollow us onFacebook- Page - https://www.facebook.com/NerdsAmalgamated/- Group - https://www.facebook.com/groups/440485136816406/Twitter - https://twitter.com/NAmalgamatedSpotify - https://open.spotify.com/show/6Nux69rftdBeeEXwD8GXrSiTunes - https://itunes.apple.com/au/podcast/top-shelf-nerds/id1347661094RSS - http://www.thatsnotcanonproductions.com/topshelfnerdspodcast?format=rssInstagram - https://www.instagram.com/nerds_amalgamated/General EnquiriesEmail - Nerds.Amalgamated@gmail.comRate & Review us on Podchaser - https://www.podchaser.com/podcasts/nerds-amalgamated-623195
En este episodio, tocamos tres temas que nos tocan en lo más profundo, por triviales que parezcan. Hablamos del oxígeno, que fue detectado por primera vez en su forma respirable fuera de la galaxia, pero que eso no le va a servir a un animal recién descubierto que resulta que no lo usa; también platicamos de un modelo físico para explicar la vida de las dunas (sí, las de arena), y finalmente, nuestra invitada Tania Alonso Vásquez nos habló de su tema de estudio, el microbioma, y de la necesidad de hacer modelos matemáticos para conocerlo mejor (y determinar al fin si esos famosos transplantes fecales funcionan). Poop science! Menú 00:20 - Saludos y presentaciones 01:59 - Oxígeno extragaláctico y animales anaerobios 21:41 - La vida de las dunas 39:52 - ¡Microbiota!

We couldn’t make podcasts without the science of sound. There’s a lot of technology involved in capturing the vibrations we’re making with our vocal folds so that we can share them with the whole Internet! So this week, we’re fine-tuning our knowledge of sound. Do scientists even know why music makes us feel emotions? Is the ocean really as silent as it seems, or are fish partying down there? And how did computer nerds send each other video games and Christmas cards through radio broadcasts? Follow us on Twitter @SciShowTangents, where we’ll tweet out themes for upcoming episodes and you can ask the science couch questions!

Harmony is one of the elemental building blocks that makes up music. This episode explores the science behind harmony and presents research that shows how the brain responds to harmony in music. Example of mathematics in certain sounds:"A tuba tends to vibrate at a set of frequencies that are mathematically related by whole number ratios. When a pencil is dropped on the floor, it vibrates with a number of frequencies, producing a complex sound wave that is noisy...this object will vibrate at a set of frequencies that have no simple mathematical relationship between them." -PhysicsClassroom.comTuba: 200Hz, 400Hz, 600Hz, 800Hz, 1000HzDropped Pencil: 197Hz, 211Hz, 217Hz, 219Hz, 287Hz, 311Hz, 329Hz, 399Hz Research Reference: Physical Review Letters, DOI 10.1103/PhysRevLett.107.108103Web Reference: NewScientist.com, Why Harmony Pleases the BrainSupport the show (https://www.patreon.com/mindbodymusiccenter)

#94: Amazon Welfare and Thermodynamics This episode is the remainder of epsiode 93 that they did not record Tuesday due to the length of the discussion on the Charlottesville Terrorist Attack. But this episode comes back strong talking about how Amazon is getting corporate welfare and tax breaks. The show will end on their science segment talking about an article that discusses whether the 2nd law of thermodynamics holds the key to the origins of life. #AmazonWelfare #thermodynamics #Creation #OriginsofLife #Evolution #CorporateWelfare Subscribe: http://www.spreaker.com/user/cellardoorskeptics Facebook: https://www.facebook.com/CellarDoorSkeptics RSS Feed: https://www.spreaker.com/user/8326690/episodes/feed iTunes: https://itunes.apple.com/us/podcast/cellar-door-skeptics/id1044088575?mt=2&ign-mpt=uo%3D4 Website: http://cellardoorskeptics.com Stitcher: http://www.stitcher.com/podcast/cellar-door-skeptics Patreon: https://www.patreon.com/cellardoorskeptics PayPal: https://www.paypal.me/CellarDoorSkeptics Intro Music: http://aloststateofmind.com/ Links ------ Please consider supporting the resistance by helping give to the legal funds of the counter protesters: https://fundly.com/solidarity-c-ville-7-8-anti-racist-legal-fund ------ http://www.mlive.com/business/index.ssf/2017/06/amazon_seeks_5m_tax_break_for.html https://www.bizjournals.com/seattle/news/2017/06/13/amazon-washington-state-tax-breaks-robot-warehouse.html http://www.goodjobsfirst.org/news/amazon-received-241m-subsidies-warehouses https://www.bna.com/amazon-close-breaking-n57982085432/ https://www.bloomberg.com/news/articles/2017-03-14/your-tax-dollars-subsidize-amazon-are-the-jobs-worth-it ------ https://www.wired.com/story/controversial-new-theory-suggests-life-wasnt-a-fluke-of-biologyit-was-physics/ http://web.mit.edu/physics/people/faculty/england_jeremy.html http://www.pnas.org/content/114/29/7565.abstract https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.119.038001

We’ve already talked a little bit about the Earth’s magnetic field, but where does that fall in terms of geoscience? Lots of physicists look at the magnetic field, but so do geologists. Not just our current field, but the ancient magnetic field, which is called paleomagnetism.

Summer is an ideal time to learn new things and explore new ideas. This week we discuss what we want to learn over the summer and how we are going to accomplish these goals. What’s your summer manifesto? Also we get showered by cosmic rays and lightning as part of #FunPaperFriday. John’s Summer Manifesto Learn Swift programming language for mobile computing development Lynda.com Books Having a project is essential to learning a programming language. Develop classroom materials to go with some demonstrations and videos I have collected Using screen flow to capture computer screen with voice overs Use Python notebooks to capture data analysis Host materials on GitHub for free and open access Setup more effective task automation to free mind space for work Launch Center Hazel Pythonista Submit one manuscript and have another draft ready with all data processing in reproducible notebooks Editorial for writing on the mobile LaTex for writing the final paper (try Lyx) KaleidaGraph Shannon’s Summer Manifesto I also want to spend more time on Lynda.com Learn learn! Working on my first proposal Setting up my research paperwork so I can start looking into grants Getting the first chapter of my dissertation ready for submission Hone my figure making skills Learn to talk/write less!! Actually review what I did right and wrong in my classes Try to keep a doc of these things so I can revisit them. Use more Evernote Prep for Fall Teaching a new grad class - catastrophic sedimentation (if anyone has ideas, please send them to me!) FunPaperFriday This week we read a paper about how cosmic rays could give us new insight into how lighting works. Lots of places have been experiencing storms recently with severe weather and flooding. Lighting can do lots of strange things like explode trees and make glass. It has incredible power in each strike. Schellart, P., Trinh, T. N. G., Buitink, S., Corstanje, A., Enriquez, J. E., Falcke, H., et al. (2015).

Localized wave fronts are a fundamental feature of biological systems from cell biology to ecology. Here, we study a broad class of bistable models subject to self-activation, degradation, and spatially inhomogeneous activating agents. We determine the conditions under which wave-front localization is possible and analyze the stability thereof with respect to extrinsic perturbations and internal noise. It is found that stability is enhanced upon regulating a positional signal and, surprisingly, also for a low degree of binding cooperativity. We further show a contrasting impact of self-activation to the stability of these two sources of destabilization. DOI: 10.1103/PhysRevLett.110.038102
