Welcome to the 75th episode of the Decode Quantum podcast. In our series of episodes recorded in Lindau where dozens of physics Nobel laureates met with young scientists, we had a chance to meet Bill Phillips, who is one of them, after the first episode with David Wineland.This podcast was recorded on July 1st, 2024, in Lindau, Germany during the 73rd Lindau Nobel Laureate Meeting 2024.Bill Phillips is American physicist from the same generation as Alain Aspect. He got his PhD in physics at the MIT working on nuclear magnetic resonance on the magnetic moment of the proton in H2O. He later did some work with Bose–Einstein condensates and then worked at NIST. There, he developed (actually, used) a technique to trap cold atoms in vacuum using lasers, called the Magneto-Optical Trap (MOT), in connection with an idea from Jean Dalibard, who was our previous guest. Bill is also a professor of physics at the University of Maryland. He was a laureate from the Nobel prize in physics in 1997 along with Steven Chu and Claude Cohen-Tannoudji, at the relatively early age of 49, by today's standards. It was for his work on the Zeeman slower and other techniques related to the cooling and trapping of atoms. He was also participating in the panel on the future of quantum computing with Olivier Ezratty at the Lindau conference. By the way, his mother was Italian, and he happens to speak French.The transcript from the podcast published on Olivier Ezratty's website has been edited by Bill Phillips and Olivier Ezratty. It is slightly different from the podcast audio recording to clarify the discussion content.https://www.oezratty.net/wordpress/2024/decode-quantum-with-bill-phillips

Gli stati della materia non sono solo 3: solido, liquido e gassoso. C'è anche il plasma ok, ma in realtà non tutti sono che esistono decine di altri stati. Oggi vi parlo di quello noto come Condensato di Bose-Einstein che può manifestarsi quando atomi di certi elementi chimici si trovano a temperature prossime allo zero assoluto e che permette, tra le varie cose, di osservare come si comportano le particelle elementari su scala macroscopica.

Quantum mechanics, which arose from the necessity to describe events beyond classical physics, entails the quantization of energy and wave particle duality, which are fundamental notions introduced by Planck, Einstein, and de Broglie. Heisenberg's Uncertainty Principle and Schrödinger's wavefunction formalism define quantum systems' probabilistic nature. Quantum field theory (QFT) applies these ideas to fields, characterizing particles as excitations within them, which is critical for understanding forces in the Standard Model of particle physics. Quantum computing, which takes advantage of qubits' superposition and entanglement, promises solutions to problems that classical computers cannot solve, including quantum error correction and encryption to ensure safe communication. Experimental developments such as Bose-Einstein condensates and quantum dots allow for precise control and observation of quantum systems.Become a supporter of this podcast: https://www.spreaker.com/podcast/library-of-philosophy--5939304/support.

Beyond solids, liquids, and gas lies a realm of the ultra-cold, where physics gets chillingly weird. Join Subatomic Tanvi as we explore the Bose-Einstein Condensate (BEC) - the fifth state of matter, colder than anything you can imagine. Prepare to be amazed by superfluids that defy gravity, imagine a cup of coffee defying its container and flowing upwards! Witness frictionless flow, where stirring a BEC creates a swirl that never stops. We'll even encounter quantum tornadoes, tiny whirlwinds that exist only in this bizarre state. This episode is guaranteed to send shivers down your spine and leave you questioning everything you thought you knew about the universe.

En el colegio aprendemos que los estados de la materia son el líquido, el sólido y el gaseoso. En este podcast ya hemos hablado anteriormente de otros estados de la materia como el consensado de condensado de Bose-Einstein, un estado de la materia solo posible a temperaturas extremadamente bajas pero, ¿qué ocurre si hacemos todo lo contrario? ¿y si tomamos un gas y lo calentamos a millones de grados? En este capítulo de El Orbitador hablamos del plasma, dónde podemos encontrarlo y algunas de sus interesantes aplicaciones en nuestra vida diaria. 3, 2, 1... ¡Despegamos!

U ovoj emisiji - Cvrčak. Isparavanje vode. Velika tema: odgoj djece. Vještina peglanja. Elektromotori. Istosmjerna je ipak pobijedila. Deprivacija sna. Gdje je zagađenje veće? Bose- Einstein kondenzat. Boeing Starliner se još ne vraća. Radijacija u orbiti.

Hoy vuelve nuestro amigo Francis Villatoro para hablar de dos noticias publicadas en su sección de Naukas de la Ciencia de la Mula Francis. En la primera noticia nos comenta nuestro amigo y colaborador Francis Villatoro sobre los primeros condensados de Bose–Einstein (BEC) de átomos de rubidio (Cornell y Wieman) y de sodio (Ketterle). La clave fueron las técnicas criogénicas de enfriamiento evaporativo, que atrapan los átomos en un pozo de potencial cuya profundidad se reduce de forma gradual para que se evaporen las moléculas con mayor energía cinética. Desde entonces se ha intentado lograr un BEC molecular; el primer gran paso se publicó en Science en 2008, el enfriamiento de un gas de rubiduro de potasio, KRb, a 350 nK (nanokelvins), usando la técnica STIRAP (STImulated Raman Adiabatic Passage). Tras muchos intentos fallidos, ahora se publica en Nature el primer BEC molecular de cesiuro de sodio, NaCs, formado por unas 250 moléculas enfriadas a 6 ± 2 nK que se mantiene durante 1.8 ± 0.1 segundos (tiempo en el que se van perdiendo moléculas hasta que su número es inferior a unas 100 y el BEC se desaparece). Todo un alarde técnico ha sido necesario para enfriar unas 30 000 moléculas de NaCs desde una temperatura de 700 ± 50 nK a tan solo 6 ± 2 nK en unos 3 segundos. Un hito que espero que muchos otros logren replicar en el próximo año. La siguiente noticia Francis nos comenta sobre el efecto Hall cuántico fraccionario que es un fenómeno contraintuitivo observado en materiales 2D bajo campos magnéticos intensos y enfriados a temperaturas criogénicas. Las cuasipartículas de tipo electrón se comportan como un líquido cuántico con fuertes correlaciones e interacciones mutuas que da lugar a nuevas cuasipartículas con carga fraccionaria, como 1/3, 1/5, o 1/7 de la carga del electrón. Además, en lugar de números cuánticos enteros o semienteros se observan valores fraccionarios, como 2/5, 4/9, 11/7, o incluso 5/23. Se publica en Science la primera simulación óptica de este efecto usando fotones en interacción. Se ha logrado simular un nivel de llenado de los niveles de Landau de 1/2 (con electrones se logran niveles de llenado 1/3, 1/5, etc.). Se ha usado una matriz de 4×4 cúbits superconductores controlados por microondas que actúan como cavidades para fotones. Como ya es habitual con las simulaciones cuánticas, los autores titulan su artículo con «realización» en lugar de «simulación». Pero que no te confunda, solo es una simulación en un ordenador cuántico analógico, cuya novedad es que promete ser escalable.

In this episode:00:46 Making a molecular Bose-Einstein condensateFor the first time, researchers have coaxed molecules into a bizarre form of matter called a Bose-Einstein condensate, in which they all act in a single gigantic quantum state. While condensates have been made using atoms for decades, the complex interactions of molecules have prevented them from being cooled into this state. Now, a team has successfully made a Bose-Einstein condensate using molecules made of caesium and sodium atoms, which they hope will allow them to answer more questions about the quantum world, and could potentially form the basis of a new kind of quantum computer.Research article: Bigagli et al. News: Physicists coax molecules into exotic quantum state — ending decades-long quest9:57 How deplatforming affects the spread of social media misinformationThe storming of the US Capitol on 6 January 2021 resulted in the social media platform Twitter (now X) rapidly deplatforming 70,000 users deemed to be sharers of misinformation. To evaluate the effect of this intervention, researchers analysed the activity of over 500,000 Twitter users, showing that it reduced the sharing of misinformation, both from the deplatformed users and from those who followed them. Results also suggest that other misinformation traffickers who were not deplatformed left Twitter following the intervention. Together these results show that social media platforms can curb misinformation sharing, although a greater understanding of the efficacy of these actions in different contexts is required.Research article: McCabe et al.Editorial: What we do — and don't — know about how misinformation spreads onlineComment: Misinformation poses a bigger threat to democracy than you might think20:14: Briefing ChatA new antibiotic that can kill harmful bacteria without damaging the gut microbiome, and the tiny plant with the world's biggest genome.News: ‘Smart' antibiotic can kill deadly bacteria while sparing the microbiomeNews: Biggest genome ever found belongs to this odd little plantSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

A scuola tutti abbiamo studiato gli stati della materia: solido, liquidi e gassoso. In realtà ce ne sono decine. Certo, per lo più rari e sfuggenti ma alcuni sono parecchio interessanti. Il quarto stato, detto plasma, è gas ionizzato, ovvero carico elettricamente ed è molto importante per un semplice motivo: è lo stato della materia più comune nell'Universo ! Le stelle ne sanno qualcosa ad esempio .. In questo episodio esplorerò tutte le caratteristiche di questo affascinante argomento, inoltre se vi interessano queste tematiche vi invito anche ad ascoltare l'episodio dal titolo "Lo stato quantistico della materia" in cui parlo del quinto stato, quello di Bose - Einstein.

This episode dives into the fascinating world of Fermions and Bosons, the fundamental building blocks of everything. We explore their unique personalities, from the solitary Fermions to the social Bosons who love to clump together. Discover how Fermions create the matter around us, and how Bosons govern the forces that hold it all together. We'll even explore the mind-bending world of Bose-Einstein condensates, where particles become superfluid and defy the laws of physics as we know them! Join us on a journey to decode the mysterious recipe of our universe!

In this episode Chris talks to Julian Schmitt, leader of the junior research group “Quantum fluids of light” at the University of Bonn. Julian recently received an ERC Starting Grant, the ML4Q Independence Grant and in 2022 he was awarded the ML4Q Young Investigator Award honoring his contribution to the cluster's program which particularly requires the collaboration between different sites. They talk about Bose-Einstein condensates and the differences between the atomic and the photonic sort. They recap how Julian got into the atomic molecular and optical physics AMO research community where major breakthroughs often seem to be possible already with relatively small teams. They also chat about how optical quantum gases can shed new light on exciting open questions in physics, such as grand canonical condensates or the interplay between quantum physics and thermodynamics.

Stato solido, liquido o gassoso. A scuola erano delle certezze, un po' come la barbabietola da zucchero e l'industria siderurgica. In verità, esistono molti più stati della materia. Oggi parlerò del "Condensato di Bose-Einstein", in cui tutte le particelle coinvolte si ritrovano nello stesso stato quantistico, permettendo di effettuare studi sulle particelle a livello macroscopico. Scopriamo in dettaglio di cosa si tratta, non prima però di aver aggiunto altre informazioni sugli stati della materia: avete presente ad esempio il plasma ed i liquidi non-newtoniani? Se volete saperne di più siete nel podcast giusto!

Carl Wieman is Cheriton Family Professor, Professor of Physics, and Professor of Education Emeritus at Stanford University and winner of the 2001 Nobel Prize in Physics for the production and observation of the first Bose-Einstein condensate. In addition to his extensive work in atomic and optical physics, Carl has pioneered the use of experimental techniques to evaluate the effectiveness of various teaching strategies for physics and other sciences. He also served as Associate Director for Science in the White House Office of Science and Technology Policy. This episode constitutes a deep dive in two directions. First, Robinson and Carl discuss the trajectory of his career and research and how it led to his work on Bose-Einstein condensates that won the Nobel Prize. Then they turn to science education, including what's wrong with it and how it can be improved.

Part of an online course on potential scientific breakthroughs:https://www.sheldrake.org/online-coursesIn this talk Rupert discusses new ways in which the hypothesis of morphic resonance can be tested, including with holistic quantum systems like Bose-Einstein condensates, with new materials like high-temperature superconductors, through experiments on cellular adaptation to toxins and heat stress, in experiments on learning in non-human animals, including nematode worms and fruit flies, and with popular online puzzles like Wordle.The implications of these tests, if successful, would be very far reaching, and could lead to new understandings of physical phenomena like the melting points of crystals, which would depend on influences from previous similar crystals, rather than on timeless laws. In biology, morphic resonance from past organisms would play an essential role in heredity, in addition to genes and epigenetic modifications of gene expression. In humans, collective memory would facilitate learning and problem-solving, and morphic resonance would underlie what the psychologist Jung called ‘the collective unconscious'._References_Mind, Memory, and Archetype: Morphic Resonance and the Collective Unconscioushttps://sheldrake.org/memoryRat Learning and Morphic Resonancehttps://sheldrake.org/ratsThe Flynn effecthttps://james-flynn.net/The Sound of a Hidden Orderhttps://www.nature.com/articles/498041aA reprogrammable mechanical metamaterial with stable memoryhttps://www.nature.com/articles/s41586-020-03123-5Evidence for unconventional superconductivity in twisted trilayer graphenehttps://www.nature.com/articles/s41586-022-04715-zAntiferromagnetic half-skyrmions and bimerons at room temperaturehttps://www.nature.com/articles/s41586-021-03219-6Conditioned aversionhttps://dictionary.apa.org/conditioned-aversionAn Experimental Test of the Hypothesis of Formative Causationhttps://sheldrake.org/roseSteven Rose's 'A hypothesis disconfirmed' refuted by Ruperthttps://sheldrake.org/rose-refutedThe Hill Effect as a Test for Morphic Resonancehttps://sheldrake.org/essays/the-hill-effect-as-a-test-for-morphic-resonance

Con Cesare Pietroiusti e Ginestra Bianconi, tra arte e matematica, un affondo nei meandri del pensiero e dei numeri. L'arte relazionale, scardina il concetto di individualità, il senso non va cercato nel singolo soggetto ma nella rete di relazioni tra soggetto e società. Nella teoria delle reti è necessario combinare in maniera scientifica e creativa dati che vengono da altri cambi disciplinari. In arte i comportamenti diventano invenzioni e i casi sono sempre unici. La creatività è fondamentale nello sviluppo della ricerca scientifica, saldamente fondata sul rigore degli studi di matematica e fisica. L'artista fa mostra della possibilità di mantenere la libertà, come generalizzazione e autoriferimenti sono le caratteristiche fondamentali del delirio, e molto altro.GUARDA IL VIDEO https://youtu.be/-wTI4vcECnc BREVI NOTE BIOGRAFICHE DEGLI AUTORICesare Pietroiusti vive e lavora a Roma.

Bose-Einstein Condensate Dark Matter That Involves Composites by A. M. Gavrilik et al. on Wednesday 23 November By improving the Bose-Einstein condensate model of dark matter through the repulsive three-particle interaction to better reproduce observables such as rotation curves, both different thermodynamic phases and few-particle correlations are revealed. Using the numerically found solutions of the Gross-Pitaevskii equation for averaging the products of local densities and for calculating thermodynamic functions at zero temperature, it is shown that the few-particle correlations imply a first-order phase transition and are reduced to the product of single-particle averages with a simultaneous increase in pressure, density, and quantum fluctuations. Under given conditions, dark matter exhibits rather the properties of an ideal gas with an effective temperature determined by quantum fluctuations. Characteristics of oscillations between bound and unbound states of three particles are estimated within a simple random walk approach to qualitatively models the instability of particle complexes. On the other hand, the density-dependent conditions for the formation of composites are analyzed using chemical kinetics without specifying the bonds formed. The obtain results can be extended to the models of multicomponent dark matter consisting of composites formed by particles with a large scattering length. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.11614v1

Intro Joining us this month is Dr Tiffany Harte, senior research associate in the group of Prof. Ulrich Schneider here at the Cavendish Laboratory. Tiffany is an experimental physicist who works with ultracold atomic systems. These are gases of neutral elements like Rubidium or Lithium which are cooled down to incredibly low temperatures and used to probe with extreme precision fundamental properties of quantum matter which would otherwise be inaccessible in other kinds of experiments, for instance in material science. She has done research at St. Andrews, Oxford, and now Cambridge, working on all the aspects of ultracold experiments, from devising optical traps, to performing quantum simulation of exotic lattices, to engineering the next generation of cooling and transport instruments. Her latest project is very ambitious: in a consortium of 7 UK universities, she is trying to build a new type of interferometer with the ultimate goal of detecting dark matter and gravitational waves.Tiffany is also a very passionate outreach communicator. She is interested in finding new and creative ways of presenting her research, for instance by combining it with dance or devising board games inspired by the physics she sees in the lab. Her goal is to make science fun and understandable for a range of different audiences, from children to adults. In today's episode, we'll talk to her about the challenges of devising experiments at the limits of zero temperature, on how to find motivation when experiments break down, and how to navigate postdoc life in and out of the pandemic.Stay with us…Please help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future.

Clean and efficient energy storage technologies are essential to establishing a renewable energy infrastructure. Lithium-ion batteries are already dominant in personal electronic devices and are promising candidates for reliable grid-level storage and electric vehicles. It is very important to improve their charging rates and usable lifetimes. To do so scientist need to understand the changes occurring inside an operating battery. Researchers at the Cavendish have now developed a low-cost lab-based optical microscopy technique to study lithium-ion batteries. The key advantages of the methodology will enable further exploration of what happens when batteries fail and how to prevent it. The technique can be applied to study almost any type of battery material, making it an important piece of the puzzle in the development of next-generation batteries.[28:12] – Most recent experiment on AION project[37:31] – Outreach, Public Engagement and sharing the love for science [42:37] – Research Staff Committee role [46:25] – Outro--- Useful links: Visit Atom Interferometry webpage to understand...

Finite temperature effects on magnetized Bose-Einstein condensate stars by Gretel Quintero Angulo et al. on Monday 12 September We study the role of temperature and magnetic field on the equation of state and macroscopic properties of Bose-Einstein condensate stars. These compact objects are composed of a condensed gas of interacting neutral vector bosons coupled to a uniform and constant magnetic field. We found that the main consequence of a finite temperature in the magnetized equations of state is to increase the inner pressure of the star. As a consequence, magnetized hot Bose-Einstein condensate stars are larger and heavier than their zero-temperature counterparts. However, the maximum masses obtained by the model remain almost unchanged, and the magnetic deformation of the star increases with the temperature. Besides, augmenting the temperature reduces the number of stable stars, an effect that the magnetic field enhances. The implications of our results for the star's evolution, compactness, redshift, and mass quadupolar moment are also analyzed. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.00136v2

Very early in our school career, we learn about the states of matter. This table is hard wood - it's solid. This water flows, we can drink it - it's a liquid. And the air around us, even though we cannot see it, is a gas. But these three states of matter are not the only three. In fact, wikipedia describes around 20 different states of matter. One of these is the Bose-Einstein condensate (BEC). In this state, a number of separate atoms or subatomic particles are cooled to near absolute zero, and behave like a single quantum entity. Many become one in the eyes of physics and maths. Since these eyes tend to define our scientific reality, the existence and implications of BECs defy our expectations of how matter should behave. It is another mind-bending quantum phenomenon. Bose-Einstein condensates are interesting to consider from a theoretical perspective, but they also have practical purposes, such as in superconductors and atomic clocks, especially now that they have been created in labs.https://whatwedontknow.buzzsprout.com/

We were all waiting for a movie featuring Bose-Einstein condensates and with Spectral our wish was Granted! Paul and Rick also discuss Backrooms, and you can watch the videos mentioned here. They also discuss Paris syndrome.

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: Evaporative Cooling of Group Beliefs , published by Eliezer Yudkowsky on the AI Alignment Forum. Early studiers of cults were surprised to discover than when cults receive a major shock—a prophecy fails to come true, a moral flaw of the founder is revealed—they often come back stronger than before, with increased belief and fanaticism. The Jehovah's Witnesses placed Armageddon in 1975, based on Biblical calculations; 1975 has come and passed. The Unarian cult, still going strong today, survived the nonappearance of an intergalactic spacefleet on September 27, 1975. Why would a group belief become stronger after encountering crushing counterevidence? The conventional interpretation of this phenomenon is based on cognitive dissonance. When people have taken “irrevocable” actions in the service of a belief—given away all their property in anticipation of the saucers landing—they cannot possibly admit they were mistaken. The challenge to their belief presents an immense cognitive dissonance; they must find reinforcing thoughts to counter the shock, and so become more fanatical. In this interpretation, the increased group fanaticism is the result of increased individual fanaticism. I was looking at a Java applet which demonstrates the use of evaporative cooling to form a Bose-Einstein condensate, when it occurred to me that another force entirely might operate to increase fanaticism. Evaporative cooling sets up a potential energy barrier around a collection of hot atoms. Thermal energy is essentially statistical in nature—not all atoms are moving at the exact same speed. The kinetic energy of any given atom varies as the atoms collide with each other. If you set up a potential energy barrier that's just a little higher than the average thermal energy, the workings of chance will give an occasional atom a kinetic energy high enough to escape the trap. When an unusually fast atom escapes, it takes with it an unusually large amount of kinetic energy, and the average energy decreases. The group becomes substantially cooler than the potential energy barrier around it. In Festinger, Riecken, and Schachter's classic When Prophecy Fails, one of the cult members walked out the door immediately after the flying saucer failed to land. Who gets fed up and leaves first? An average cult member? Or a relatively skeptical member, who previously might have been acting as a voice of moderation, a brake on the more fanatic members? After the members with the highest kinetic energy escape, the remaining discussions will be between the extreme fanatics on one end and the slightly less extreme fanatics on the other end, with the group consensus somewhere in the “middle.” And what would be the analogy to collapsing to form a Bose-Einstein condensate? Well, there's no real need to stretch the analogy that far. But you may recall that I used a fission chain reaction analogy for the affective death spiral; when a group ejects all its voices of moderation, then all the people encouraging each other, and suppressing dissents, may internally increase in average fanaticism.1 When Ayn Rand's long-running affair with Nathaniel Branden was revealed to the Objectivist membership, a substantial fraction of the Objectivist membership broke off and followed Branden into espousing an “open system” of Objectivism not bound so tightly to Ayn Rand. Who stayed with Ayn Rand even after the scandal broke? The ones who really, really believed in her—and perhaps some of the undecideds, who, after the voices of moderation left, heard arguments from only one side. This may account for how the Ayn Rand Institute is (reportedly) more fanatical after the breakup than the original core group of Objectivists under Branden and Rand. A few years back, I was on a transhumanist mailing list where a small group espousing “social...

As Moore's Law slows, people are starting to look for alternatives to the silicon chips we've long been reliant on. A new optical switch up to 1,000 times faster than normal transistors could one day form the basis of new computers that use light rather than electricity. The attraction of optical computing is obvious. Unlike the electrons that modern computers rely on, photons travel at the speed of light, and a computer that uses them to process information could theoretically be much faster than one that uses electronics. The bulkiness of conventional optical equipment long stymied the idea, but in recent years the field of photonics has rapidly improved our ability to produce miniaturized optical components using many of the same techniques as the semiconductor industry. This has not only led to a revived interest in optical computing, but could also have significant impact for the optical communications systems used to shuttle information around in data centers, supercomputers, and the internet. Now, researchers from IBM and the Skolkovo Institute of Science and Technology in Russia have created an optical switch—a critical component in many photonic devices—that is both incredibly fast and energy-efficient. It consists of a 35-nanometer-wide film made out of an organic semiconductor sandwiched between two mirrors that create a microcavity, which keeps light trapped inside. When a bright “pump” laser is shone onto the device, photons from its beam couple with the material to create a conglomeration of quasiparticles known as a Bose-Einstein condensate, a collection of particles that behaves like a single atom. A second weaker laser can be used to switch the condensate between two levels with different numbers of quasiparticles. The level with more particles represents the “on” state of a transistor, while the one with fewer represents the “off” state. What's most promising about the new device, described in a paper in Nature, is that it can be switched between its two states a trillion times a second, which is somewhere between 100 and 1,000 times faster than today's leading commercial transistors. It can also be switched by just a single photon, which means it requires far less energy to drive than a transistor. Other optical switching devices with similar sensitivity have been created before, but they need to be kept at cryogenic temperatures, which severely limits their practicality. In contrast, this new device operates at room temperature. There's still a very long way to go until the technology appears in general-purpose optical computers, though, study senior author Pavlos Lagoudakis told IEEE Spectrum. “It took 40 years for the first electronic transistor to enter a personal computer,” he said. “It is often misunderstood how long before a discovery in fundamental physics research takes to enter the market.” One of the challenges is that, while the device requires very little energy to switch, it still requires constant input from the pump laser. In a statement, the researchers said they are working with collaborators to develop perovskite supercrystal materials that exhibit superfluorescence to help lower this source of power consumption. But even if it might be some time until your laptop is sporting a chip made out of these switches, Lagoudakis thinks they could find nearer-term applications in optical accelerators that perform specialized operations far faster than conventional chips, or as ultra-sensitive light detectors for the LIDAR scanners used by self-driving cars and drones.

Carl Wieman is a professor of physics at Stanford Uni- versity, professor in the Stanford Graduate School of Education, and a DRC professor in the Stanford Univer- sity School of Engineering. In 2001, he—along with Eric Allin Cornell, Wolfgang Ketterle, and their teams—was awarded the Nobel Prize in Physics “for the achievement of Bose–Einstein condensation in dilute gases of alkali atoms, and for early fundamental studies of the properties of the condensates.” He was also a recipient of the 2020 Yidan Prize for education research. His indefatigable work to revolutionize the way professors teach—and students learn—was the subject of our conver- sation. The first question I asked was, “If somebody says, ‘I have good news for you and bad news for you,' which do you want to hear first?” Without skipping a beat, he said he'd want the bad news because “it turns out negative feedback contributes much more to learning than positive feedback does.” Wieman himself is dedicated to continued learning. This is only one of the qualities I find so inspiring in him. We are all educators and leaders, just in different ways, jobs, and positions. And it is impossible to be a good educator and leader without also being a good student. As Carl argues, one of the things we have to learn is how to teach. The field of teaching needs better best practices. We need to work smarter, not harder. I admire the way Carl is now applying the same mental tenacity and clarity of purpose he used in the laboratory to his work in education. He realized that teaching is not dissimilar to the processes by which he conducted research—namely, that both are problem-solving exercises and involve certain hypotheses that need to be reexamined. As Carl points out, it's important to question assumptions and look at things in new ways. He argues that teachers have to be students and have to continue learning—and that they are not currently doing a good job of it. This is disruptive. The bad news: Carl equates current teaching styles to bloodletting. The good news: he doesn't think that teaching well will ultimately take much more time than we're currently spending.  Available on Amazon: Think Like a Nobel Prize Winner About Professor Brian Keating: https://www.youtube.com/drbriankeating Podcast in iTunes https://simonsobservatory.org/ https://briankeating.com/ https://bkeating.physics.ucsd.edu/ https://www.linkedin.com/in/drbriankeating/

In this episode, we have our first guest, our good friend Gautam, who rambles about cool stuff from granular gases to superfluids.

The StoryThe Liquid Light Sauvignon 2018 is a wine brand from Chateau Ste Michelle's family of wines sourced from grapes on 68% Horse Heaven Hills AVA and 32% Yakima AVA of Washington State. Chateau Ste Michelle is by far the largest winery in Washington and according to several winemakers I have talked to over the years, they are a very good neighbor.A few years ago you would have seen Columbia Valley as the vineyard location, but Washington wines seem to have done some rebranding. I don't know if folks thought Columbia Valley was located in California or what, but the labels now say Washington State along with the sub-AVA. This puts more emphasis on the individual growing areas in Washington, which is a good thing.The name Liquid Light is a reference to the 5th form of matter that was recently discovered. I am only aware of the first four, there is yes, it matters, no it doesn't matter, well if it matters that much to you, then ok, and I don't know let me think about it. Yes, I am a scientist.The fifth form of matter is the Bose-Einstein condensate and even after reading the explanation, I have no idea what it is. The other 4 are solids, liquids, gases, and plasma, what any of that has to do with Sauvignon Blanc, I do not know.I am a fan of Sauvignon Blanc, but I am not overly familiar with Washington State Sauv Blanc. The grapes are sourced from cool-climate growing AVAs and Chateau Ste Michelle has an excellent track record for producing affordable wines, I found this for $9.99. The alcohol content is a mild 12.0%.Liquid Light Sauvignon Blanc 2018 Tasting NotesThe color is a pale, clear wheat yellow. The nose is interesting, it is very different from New Zealand Sauvignon Blanc, there is a mix of peach, lemon, and pear, a little grapefruit, lime, and a distinct grassy aroma. This Sauv Blanc has a soft smooth mouthfeel and tart flavors.It starts with peach, apricot, a touch of honey, grapefruit, pear, and lime. The mid-palate lemon, juicy apple, a little salty sensation, and not sweet pineapple.The SummaryThe Liquid Light Sauvignon Blanc 2018 is no copycat Sauv Blanc, it is a different take, but a very tasty take.The Liquid Light has a great deal of flavor and really good acidity, which is excellent combination.

Phil Schewe discusses how matter, such as atoms and electrons, can display wave-like properties. Steve Rolston describes early scattering experiments. Gretchen Campbell talks about matter waves in the context of modern Bose-Einstein condensate experiments.
