Some people call him the Space Lawyer, some call him an entrepreneur... in today's episode, Kevin and Laura dive into the laws of the cosmos with Christopher Hearsey, an accomplished space executive, lawyer, and entrepreneur with nearly two decades of leadership in the space industry. With expertise spanning space law, mission management, and strategy, Chris provides unique insights into the challenges and opportunities in the growing space economy. We kick off by answering a fundamental question: what does a space lawyer do? Chris explains the origins of space law, the 1967 Outer Space Treaty, and how these foundational principles apply to today's technological advancements like reusable rockets and private moon missions. He details key topics such as Moore's Law in space, the role of space in telecommunications technology, and the regulatory complexities of landing commercial habitats on the moon. Chris explains how space governance works, who gets to send missions to space, own property, and govern activities in space. We also cover space piracy, interplanetary lawsuits, and the cultural significance of space exploration. Chris also shares his thoughts on ethical considerations in space exploration, the challenges of colonizing Mars, and what it will take for commercial moon flights to become a reality. Plus, we get his take on important pop culture questions like Mulder or Scully? and hear about Kevin's "all-expenses-paid" space travel deal—with a twist. Tune in for a mix of deep space insights, practical advice for aspiring space entrepreneurs, and a little humor as we explore humanity's legal path to the stars.Christopher Hearsey is an experienced space executive, space lawyer, and entrepreneur with almost two decades of leadership in the space industry.

String theory, the current leading candidate for a theory of quantum gravity as well as other particles and forces, doesn't connect directly to the world we see. It's possible that there is a large landscape of possible states of theory, with the hope that one of them represents our universe. The existence of a landscape implies the existence of a corresponding swampland -- universes that are not compatible with string theory. I talk with Cumrun Vafa, a respected physicist and originator of the swampland program, about how we might use constraints on what kinds of physics are compatible with string theory to make predictions about cosmology and other experimental regimes.In the conversation we refer to a famous diagram representing different ten-dimensional string theories, as well as 11-dimensional M-theory, as different limits of an underlying fundamental theory.Support Mindscape on Patreon.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/05/27/277-cumrun-vafa-on-the-universe-according-to-string-theory/Cumrun Vafa received his Ph.D. in physics from Princeton University.

Curt Jaimungal is a Torontonian filmmaker and podcast host, with a Degree in Mathematical Physics from the University of Toronto. His channel "Theories of Everything" (TOE) analyses various "Theories of Everything" by exploring theoretical physics, consciousness, Ai, and God in a technically rigorous manner. Similar to Mind-Body Solution, a separating factor of TOE from other podcasts is its focus on depth even at the risk of limiting the audience due to how much detail we delve into subjects. Paralleling the intensity found in academic discourse, Curt is increasingly embracing a spectrum of unconventional ideas to conduct research during this podcast, rather than merely conveying existing information. If you enjoy Mind-Body Solution, you'll love Theories of Everything - check out his channel, like, and subscribe!

If you haven't noticed, the concept of achievement and even competitiveness has weighed heavily on my mind as of late. A gift of the nontraditional life is the opportunity to step back and see the world around us with a degree of unusual clarity, far from the treadmill. For years I valued athletic and professional progress in ways that weren't making my life better, but I thought they were. I searched for and implemented solutions to the wrong problems. Meanwhile, what truly mattered—mainly my relationships—withered on the vine. The journey toward rectifying these tendencies continues today. My guest today, Lincoln Stoller, is a former mountaineer who now specializes in psycho-, hypno-, and neurofeedback therapy, in tandem with numerous other counseling and coaching services. Lincoln holds a PhD in Theoretical and Mathematical Physics from UT Austin, including a post-doc assignment at UC Berkley. Lincoln eventually moved from quantum physics to create a management and automation software platform for businesses, learned to build Norwegian log homes, traveled and lived abroad in far-flung foreign lands, and is even a certified pilot. To say Lincoln lives well outside of the bounds of normalcy is probably a half-truth at best. As he says in the interview, we should “just keep doing out-of-the-box stuff. And if people are calling you a little crazy or a little nutty, then you probably aren't exploring enough of the boundaries.” Today's conversation revolves around the high-risk potential of hard-charging performers and achievers, whether they exist in sports, business, or other areas of life. While these individuals hold our collective attention and admiration, Lincoln outlines how their psychological roots run shallow. They often struggle to stay satisfied with themselves or those around them. Lincoln might even say he holds an anti-hard-man philosophy. I think you'll see why. Support this project: Buy Me a CoffeeSubscribe to the website: SUBSCRIBE ME!Show Notes and Links at Clippingchains.com Topics Discussed with Lincoln StollerQuantum physics to therapist/coachLincoln's history in mountaineering amongst some of the legends of the sportWhy almost all climbers are “high-risk”“Resilience is not throwing yourself at a climb until you are torn and bloody, it's exploring your limits and working them gracefully.”Why some people crave riskEmotions on the rock and exploration and mastering of triggersGetting past societal expectations of productivityCan satisfied people be high performers?How dissatisfaction can lead to pathology: “If you're not satisfied with yourself, you won't be satisfied with anyone else, either.”Is competition healthy?Is personal growth selfish?What is productive suffering and why is it important?Taking ownership: the dysfunctional mental model that experts can solve our problemsHow high performers can assess mental health concerns that might not be apparentRelationships with parents and why these are often commonly fraught“You can't change people directly.

Join us for a conversation with Edward Frenkel, mathematician, Berkeley professor and author of the international bestseller Love and Math, as we explore the nature of reality and the fallacy of the naive ideas of determinism and computationalism. Drawing on the landmark achievements of modern mathematics and quantum physics, Frenkel makes the case that consciousness is not computational, that intuition and imagination cannot be captured by algorithms. A regular presenter at the SAND conferences, Frenkel has long argued that the debate about the capabilities and dangers of artificial intelligence can be traced to the question “Who am I?” Hence it creates an opportunity for us to go deeper on the path of self-inquiry. To facilitate this process, it is essential to let go of the misconceptions of the science of the 19th century and to update our worldview with the paradigms of the science of the 21st century. A mind-expanding dialogue about the Infinite nature of consciousness, limits of knowledge, and the alchemy of transformation. Edward Frenkel is a professor of mathematics at University of California, Berkeley, member of the American Academy of Arts and Sciences, and winner of the Weyl Prize in Mathematical Physics. He is the author of the international bestseller Love and Math which has been published in 19 languages.

Given the increasing concerns from consumers regarding the welfare of cows, particularly calves, it is crucial to prioritize and ensure the well-being of the animals. However, this responsibility should not be viewed only as an obligation, but also as an opportunity to enhance both animal comfort and production outcomes. In this episode, we delve into calf welfare with the comprehensive considerations of Dr. Emily Miller-Cushon. She talks about the pros and cons of individual and group housing systems, strategies to reduce abnormal behaviors and cross-suckling in calves, as well as holistic approaches for managing calves until weaning. “We have observed that animals develop preferences for feeds that others are eating.

Today's show is a really unique show in many ways. My guest Robert Grant, and I go into levels of water that have never been spoken about before in this podcast and maybe nowhere else. And it's a really fun conversation and you're going to see, hopefully the world from a new perspective and get some more insight from this very brilliant man and the way that he perceives the world and water. And a little bonus is relationships. This is a very high level human. Not only has he lived in nine different countries, Robert Grant's career and life have spanned a very broad spectrum of interests and educational disciplines. So professionally, he played a leading role in the global health care industry. Formerly the CEO of Bausch + Lomb and Allergan, and he covered diverse areas such as pharmaceutical, medical, device technology and as well as international health care systems. He's done TEDx talks, but what he's really known for now is his mathematics and geometry. Most recently, during the past decade, Robert has turned his attention and acumen toward number theory, mathematical physics, geometry, cryptography and blockchain cryptocurrencies. So he's a strong advocate of data sovereignty for the original producers of digital assets. So Robert and I talk water, we talk philosophical things, we talk relationships. He get real and we get deep. Please share this episode with somebody that you love.

John Baez is a mathematical physicist, professor of mathematics at UC Riverside, a researcher at the Centre for Quantum Technologies in Singapore, and a researcher at the Topos Institute in Berkeley, CA. John has worked on an impressively wide range of topics, pure and applied, ranging from loop quantum gravity, applications of higher categories to physics, applied category theory, environmental issues and math related to engineering and biology, and most recently on applying network theory to scientific software. Additionally, John is a prolific writer and blogger. This first began with John's column This Week's Finds in Mathematical Physics, which ran 300 issues between 1993 and 2010, which then continued in the form of his ongoing blog Azimuth. Last but not least, John is also a host and contributor of the popular blog The n-category Cafe.   In this episode, we dive into John Baez and John Huerta's paper “The Algebra of Grand Unified Theories” which was awarded the Levi Conant Prize in 2013. The paper gives a crash course in the representation theory underlying the Standard Model of particle physics and its three most well known Grand Unified Theories (GUTs): the SU(5), SO(10) (aka Spin(10)), and Pati-Salam theories. The main result of Baez-Huerta is that the particle representations underlying the three GUTs can in fact be unified via a commutative diagram. We dive deep into the numerology of the standard model to see how the SU(5) theory naturally arises. We then make brief remarks about SO(10) and Pati-Salam theories in order to state the Baez-Huerta theorem about their organization into a commutative square: a unification among grand unifications!   Notes:  While we do provide a crash course on SU(2) and spin, some representation theory jargon is used at times in our discussion. Those unfamiliar should just forge ahead! We work in Euclidean signature instead of Lorentzian signature. Other than keeping track of minus signs, no essential details are changed.  Part I.

Law firms are sweet targets for hackers given the rich data they store, from intellectual property to confidential merger details to personal and health information and more.  The last decade is littered with headlines about data hacks and ransomware attacks at even the most sophisticated global law firms. Yet, according to the 2020 Legal Technology Survey Report conducted by the American Bar Association's Legal Technology Resource Center (LTRC) fewer than half of the firms polled employ some of the most basic security measures, such as email and file encryption.  What can smaller firms do to protect their data and that of their clients? Joining me to discuss this important issue is Ondrej Krehel, CEO & Founder of LIFARS, a New York City based incident response and digital forensics firm specializing in solutions to optimize an organization's cybersecurity protections. Ondrej is recognized for his digital forensic expertise and ethical hacking skills He participates in high-profile engagements around the world using his proprietary methodology to achieve the most rapid root-cause analysis and remediation. He is a former lecturer at FBI Training Academy who has led forensic investigations and cybersecurity involving the U.S. government, including military cyber special operations.  He holds an Ph.D. in Computer Forensics from Police Academy in Bratislava, Slovakia, and M.S. degree in Mathematical Physics from Comenius University in Bratislava and an Engineering Diploma from Technical University in Zvolen, Slovakia. Joining Ondrej and me is Gaspare J. Marturano, Chief Marketing Officer at LIFARS. Gaspare is a former Director of Information Systems for a large Connecticut law firm and has consulted on these issues with a number of other law firms.   This podcast is the audio companion to the Journal on Emerging Issues in Litigation, a collaborative project between HB Litigation Conferences and the Fastcase legal research family, which includes Full Court Press, Law Street Media, and Docket Alarm. If you have comments or wish to participate in one our projects, or want to tell me how insightful and informative Ondrej and Gaspare are, please drop me a note at Editor@LitigationConferences.com.  I particularly enjoyed hearing about what one kid was doing at 17, an age when I was certain I would be sought out for my rock drumming artistry.

* A Fun RSR List Show: For this Thanksgiving weekend, a special rebroadcast. In  our List of the Fine-Tuned Features of the Universe, Real Science Radio host Bob Enyart quotes leading scientists and their astounding admission of the uncanny and seemingly never-ending list of the just-perfect finely-tuned parameters of the physical features of the Earth, the solar system, and the entire cosmos. This program is brought to you by God, maker of heaven and earth and other fine products! * The Finely Tuned Parameters of the Universe: Barrow & Tipler, in their standard treatment, The Anthropic Cosmological Principle, admit that "there exist a number of unlikely coincidences between numbers of enormous magnitude that are, superficially, completely independent; moreover, these coincidences appear essential to the existence of carbon-based observers in the Universe." Examples include the wildly unlikely combination of: - there is the same number of electrons as protons to a standard deviation of one in ten to the thirty-seventh power, that is, 1 in 10,000,000,000,000,000,000,000,000,000,000,000,000 (37 zeros) - the 1-to-1 electron to proton ratio throughout the universe yields our electrically neutral universe - all fundamental particles of the same kind are identical (including protons, electrons, down quarks, etc., even, in QED, photons!) - energy exactly equals mass (times the conversion factor of c²) - the electron and the massively greater proton have exactly equivalent opposite charges - the electron to proton mass ratio (1 to 1,836) is perfect for forming molecules - the baryon (protons, neutrons, etc.) that decays must conserve the number of baryons - the free neutron decays in minutes whereas it is stable within the nuclei of all the non-radioactive elements (otherwise eventually only hydrogen would exist because the strong nuclear force needs neutrons to overcome proton repulsion) - the proton can't decay because it is the lightest baryon (otherwise all elements would be unstable) - the electromagnetic and gravitational forces are finely tuned for the stability of stars - the gravitational and inertial mass equivalency - the electromagnetic force constant is perfect for holding electrons to nuclei - the electromagnetic force is in the right ratio to the nuclear force - the strong force if changed by 1% would destroy all carbon, nitrogen, oxygen, and heavier elements - the precise speed of light, the square root of the inverse of the product of space's permeability and permittivity (i.e., its magnetic field resistance, 4π * 10-7 Weber/Amps * meter, multiplied by its electric field resistance, or 8.8542 * 10-12 Coulomb2 /Newton * meter2), or 186,282 MPS, is integral for life - etc., etc., etc. (including the shocking apparent alignment of the universe with the orbit of the Earth) Leading atheist physicist and biologist admit* The Most Famous Scientist Atheists Agree: The world's most famous scientist atheists in physics and biology have fully admitted half the question as to fine tuning, that the world APPEARS to have been fine tuned. Richard Dawkins: "Biology is the study of complicated things that give the appearance of having been designed for a purpose." Stephen Hawking: "The remarkable fact is that the values of these numbers seem to have been very finely adjusted..." * An Atheist's Index to Replies: Here's an index to (failed) attempts to rebut the fine-tuning argument for God's existence.  * Omitting the Cosmological Constant: We have omitted from this list the commonly reported fine-tuning of the cosmological constant to one part in 10 to the 120th. This is so very precise that if the entire universe had as much additional mass as exists in a single grain of sand, it would all collapse upon itself. That is, if a big bang actually formed our universe, and if it created a miniscule additional amount of mass than it is claimed to have created, then no planets, stars, or galaxies could exist. Conversely, if the universe had less mass, by that same quantity, matter never would have coalesced to become planets, stars, and galaxies, and again, we would not exist. So, why doesn't Real Science Radio include this astoundingly fine-tuned parameter in our list? Well, as physicist John Hartnett points out, the cosmological constant is only a fine-tuning problem for the big bang theory, so it is an argument only against a big bang universe, whereas in our actual universe, it is not a fine tuning issue. So, the cosmological constant problem, also known as the vacuum catastrophe, does refute big bang cosmology, at least, for anyone who is objective, has common sense, and is not desperately trying to ignore the evidence for the Creator. (By the way, since NASA says that the confirmed predictions of the big bang theory are what validates it, you might want to Google: big bang predictions, and you'll find our article ranked #1 out of half-a-million, at rsr.org/bbp, presenting the actual track record of the predictions of the theory. Also, if you Google: evidence against the big bang, you'll find our article on that topic near the top of the first page of Google results!) * The Whopping Physics Coincidence: NewScientist reports about gravity and acceleration that, "a large chunk of modern physics is precariously balanced on a whopping coincidence" for, regarding gravitational and inertial mass, "these two masses are always numerically exactly the same. The consequences of this coincidence are profound..." * The Finely Tuned Parameters of the Solar System include: - Our Sun is positioned far from the Milky Way's center in a galactic Goldilocks zone of low radiation - Our Sun placed in an arm of the Milky Way puts it where we can discover a vast swath of the entire universe - Our Sun is in the unusual Local Bubble, 300 light years of extremely diffuse gas, 1/500th of the average - Earth's orbit is nearly circular (eccentricity ~ 0.02) around the Sun providing a stability in a range of vital factors - Earth's orbit has a low inclination keeping its temperatures within a range permitting diverse ecosystems - Earth's axial tilt is within a range that helps to stabilize our planet's climate - the Moon's mass helps stabilize the Earth's tilt on its axis, which provides for the diversity of alternating seasons - the Moon's distance from the Earth provides tides to keep life thriving in our oceans, and thus, worldwide - the Moon's nearly circular orbit (eccentricity ~ 0.05) makes its influence extraordinarily reliable - the Moon is 1/400th the size of the Sun, and at 1/400th its distance, enables educational perfect eclipses - the Earth's distance from the Sun provides for great quantities of life and climate-sustaining liquid water - the Sun's extraordinary stable output of the energy - the Sun's mass and size are just right for Earth's biosystem - the Sun's luminosity and temperature are just right to provide for Earth's extraordinary range of ecosystems - the color of the Sun's light is tuned for maximum benefit for photosynthesis - the Sun's low "metallicity" prevents the destruction of life on Earth -

In this new COVID-19 series of McKay Interviews, Michael will be asking different experts their views on the pandemic and how it will develop - and ultimately defeated. This week, Michael is speaking to Bob Bishop. He has been on the show before. He is the Founder & President of the International Centre for Earth Simulation Foundation, ICES, and a former Chairman & CEO of Silicon Graphics, Inc., once a Fortune 500 company but now absorbed by Hewlett Packard Enterprise. Bob holds degrees in Mathematical Physics from the University of Adelaide and New York University, and is a Doctor of Science from the University of Queensland. In 2006, he was awarded the NASA Distinguished Public Service Medal for his role in building simulation facilities that helped NASA’s space shuttle fleet return-to-flight after the 2003 Columbia disaster.

Gudrun talks to Anna Geyer. Anna is Assistant professer at TU Delft in the Mathematical Physics group at the Delft Institute of Applied Mathematics. She is interested in the behaviour of solutions to equations which model shallow water waves. The day before (04.07.2019) Anna gave a talk at the Kick-off meeting for the second funding period of the CRC Wave phenomena at the mathematics faculty in Karlsruhe, where she discussed instability of peaked periodic waves. Therefore, Gudrun asks her about the different models for waves, the meaning of stability and instability, and the mathematical tools used in her field. For shallow water flows the solitary waves are especially fascinating and interesting. Traveling waves are solutions of the form representing waves of permanent shape f that propagate at constant speed c. These waves are called solitary waves if they are localized disturbances, that is, if the wave profile f decays at infinity. If the solitary waves retain their shape and speed after interacting with other waves of the same type, we say that the solitary waves are solitons. One can ask the question if a given model equation (sometimes depending on parameters in the equation or the size of the initial conditions) allows for solitary or periodic traveling waves, and secondly whether these waves are stable or unstable. Peaked periodic waves are an interesting phenomenon because at the wave crest (the peak) they are not smooth, a situation which might lead to wave breaking. For which equations are peaked waves solutions? And how stable are they? Anna answers these questions for the reduced Ostrovsky equation, which serves as model for weakly nonlinear surface and internal waves in a rotating ocean. The reduced Ostrovsky equation is a modification of the Korteweg-de Vries equation, for which the usual linear dispersive term with a third-order derivative is replaced by a linear nonlocal integral term, representing the effect of background rotation. Peaked periodic waves of this equation are known to exist since the late 1970's. Anna presented recent results in which she answers the long standing open question whether these solutions are stable. In particular, she proved linear instability of the peaked periodic waves using semi-group theory and energy estimates. Moreover, she showed that the peaked wave is unique and that the equation does not admit Hölder continuous solutions, which implies that the reduced Ostrovsky equation does not admit cusps. Finally, it turns out that the peaked wave is also spectrally unstable. This is joint work with Dmitry Pelinovsky. For the stability analysis it is really delicate how to choose the right spaces such that their norms measure the behaviour of the solution. The Camassa-Holm equation allows for solutions with peaks which are stable with respect to certain perturbations and unstable with respect to others, and can model breaking waves. Anna studied mathematics in Vienna. Adrian Constantin attracted her to the topic of partial differential equations applied to water waves. She worked with him during her PhD which she finished in 2013. Then she worked as Postdoc at the Universitat Autònoma de Barcelona and in Vienna before she accepted a tenure track position in Delft in 2017. References A. Geyer, D.E.

Robert Stasio leads Dreamit’s SecureTech vertical where he sets overall strategic focus, expands the customer network, and works daily with securetech startups from around the world helping them refine their positioning and go-to-market strategy.  In addition, they assist startups to think through how to scale sales and operations and map out their capital needs along with how to raise their next round. Robert Stasio - Demand in the Private Sector During Bob's educational path he received a BS in Mathematical Physics and holds a Master’s degree in Intelligence Studies.  He also completed numerous U.S. Department of Defense professional education courses focusing on intelligence operations. Bob holds various technical certifications, including CISSP, a globally recognized standard of achievement in the cybersecurity industry. Bob joined the Army in 2001 during ROTC in college.  He then branched into Military Intelligence as an officer.  Bob new they would be deployed to Iraq during 2004-2005 so they trained Korean linguists and turned them into Arabic linguists for deep intelligence.  After they returned, General Alexander and his team plucked him out and Bob then helped NSA stand up one of the Army’s first dedicated cyber units.  It was then that he knew there was potential and demand in the private sector. “I saw the need to take this skill set and go into the private sector.” – Robert Stasio Before joining Dreamit, Bob held multiple roles at IBM Security, leading efforts in Cyber Operations and Threat Hunting. Prior to IBM, Bob worked in the private sector, leading threat intelligence programs at Bloomberg and global financial firms.  He also has deep government experience having held positions at NSA’s Cyber Center, U.S. Cyber Command, U.S. Army’s Signals Intelligence Corps, the FAA, and NASA. Bob served as a U.S. Army officer and is a recipient of numerous military awards, including the Bronze Star and Global War on Terrorism Expeditionary Medal. Bob is also a Truman National Security Fellow, Brookings Institution Council on U.S. and Italy Fellow, and serves on the advisory boards of multiple startups. Lessons Learned Many lessons were learned when Robert Stasio started his own venture.  He had the skill set, a great idea, the demand and knew technologically how it would work.  Bob had no experience in running a company and did not have a MBA.  Therefore he reached out to others who had previously started their own business for advice and help when he started his company.  Bob started with a service only business.  He learned quickly that the hockey stick approach and trying to scale your business through a service only mindset is almost impossible to do. “Services only can take you so far.  In that type of mindset it can only scale so much. It is not a venture backed business model. It is not a scalable business model from a scalability perspective.” – Robert Stasio Vision of Excellence and Profitability The goal should be to run a good company and be profitable.  In Bob's business they are looking for market validation and revenue of the product or offering you are trying to scale not the services revenue.  His advice to entrepreneurs is to grow your company by getting customers and by getting revenue.  Bob recommends getting feedback and quickly and cheaply as possible during the startup process. “Most startups fail because they run out of revenue.”-Robert Stasio To hear the rest of Robert Stasio’s transition from the Army to civilian entrepreneur, download and listen to the rest of the episode.

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

Strömungen beobachten wir fast jeden Tag. Die Meeresbrandung fasziniert uns und eine gut funktionierende Klimaanlage ist ein wunderbarer Luxus, egal ob sie wärmt oder kühlt. Strömungen zu beherrschen ist aber auch in vielen verfahrenstechnischen Zusammenhängen wichtig. Insofern haben Gleichungen, die Strömungen beschreiben, eine große praktische Relevanz und gleichzeitig eine fast emotionale Anziehungskraft. Das einfachste mathematische Modell, das auch für viele Computersimulationen genutzt wird, sind die inkompressiblen Navier-Stokes Gleichungen (INS). Hier ist die strömende Substanz dem Wasser ähnlich genug, dass nur in der Materialkonstante Viskosität verschiedene Fließfähigkeiten unterschieden werden. Als Lösungen des Systems von partiellen Differentialgleichungen suchen wir das Geschwindigkeitsfeld und den Druck als Funktionen von Raum und Zeit . Im 3d-Fall ist das ein System von vier Gleichungen. Drei davon sind eine Vektorgleichung, die aus der Impulserhaltung abgeleitet wird und die vierte ist die Erhaltung der Masse. Im inkompressiblen Fall vereinfacht sich diese aus die Forderung, dass die Divergenz des Geschwindigkeitsfeldes verschwindet. Die komplexer aussehende Gleichung ist die Vektorgleichung, weil hier die zweiten räumlichen Ableitungen des Geschwindigkeitsfeldes, der Druckgradient, die zeitliche Ableitung der Geschwindigkeit und ein nichtlinearer Term vorkommen. Die Gleichungen müssen im Strömungsgebiet gelten. Die Lösungen müssen sich aus dem Anfangszustand entwickeln (Anfangsbedingung) und am räumlichen Rand vorgeschriebenen Werten, den Randwerten (meist fordert man, dass die Geschwindigkeit Null ist) genügen. Dieses Modell ist in einem längeren Prozess entwickelt worden. Ein großer Durchbruch bei der mathematischen Analyse gelang dem französischen Mathematiker Leray im Jahr 1934. Er hatte die geniale Idee, sich von dem Wunsch zu verabschieden, für diese komplizierte Gleichung eine punktweise zutreffende Lösung zu konstruieren. Statt dessen verallgemeinerte er den Lösungsbegriff und führte den Begriff der schwachen Lösung ein. Diese erfüllt die Gleichung nur im Sinne eines ausgeklügelten Systems von unendlich vielen Integralgleichungen. Er zeigte mit Hilfe von abstrakten Argumenten, dass die INS immer solche schwachen Lösungen haben. Heute ist bekannt, dass falls eine punktweise Lösung existiert (sogenannte starke Lösung), diese eindeutig ist (also insbesondere mit der schwachen übereinstimmt), es in 2d immer eine punktweise Lösung gibt, die für alle Zeiten existiert (unter geringfügigen Bedingungen an den Rand), und es unter Kleinheitsbedingungen an die Daten und bei glattem geometrischen Rand des Gebietes auch in 3d punktweise Lösungen gibt.Wir wissen jedoch in 3d nicht, ob die gefundenen schwache Lösung regulär bzw. stark ist (d.h. eine punktweise Lösung ist.) In Vorbereitung auf den Jahrtausendwechsel gab es in der Mathematik die Bestrebung, so wie dies 100 Jahre zuvor von Hilbert geschehen war, die wichtigsten mathematischen Problemstellungen in den Fokus zu nehmen. Das Ergebnis waren sieben sogenannte Milleniumsprobleme der Clay Foundation, für deren Lösung jeweils ein Preisgeld von einer Millionen Dollar ausgelobt wurde. Eines dieser für so wichtig angesehenen Probleme ist die offene Frage der Regularität der schwachen Lösungen der INS. Woran liegt das? Eine Eigenschaft der INS, die sie schwierig macht, ist ihre Nichtlinearität. Sie ist nur quadratisch und hat eine besondere Struktur. Diese Struktur verdanken wir es z.B., dass die schwache Theorie erfolgreich ist. Es besteht Hoffnung, dass wir auch die Lücke zur starken Theorie unter Ausnutzung der Struktur schließen können. Der Standardweg im linearen Fall (z.B. beim Laplace-Problem) ist es, für die schwachen Lösungen mit einem Münchhausen-Prinzip (Elliptic Bootstrapping) Stück für Stück mehr Regularität zu zeigen. Man kann so zeigen, dass die Lösung immer so gut ist, wie die es Daten erlauben. Man nennt das maximale Regularität. Leider ist für die INS das Wachstum in der Nichtlinearität zu schnell, um im 3d-Fall mit diesen Standardmethoden zu argumentieren (im 2d Fall geht es aber). Im 3d-Fall geht es aber unter bestimmten Zusatzbedingungen, z.B. einer höheren Integrierbarkeit des Geschwindigkeitsfeldes als die schwachen Lösungen von vornherein haben. Man fand dies über Skalierungs-Eigenschaften der Gleichung heraus. Grob gesagt, muss man fordern dass die Lösung zu einem Raum gehört, der Skalierungsinvariant ist. Eine weitere zusätzliche Forderung ist die Gültigkeit der Energiegleichung (Erhaltung der kinetischen Energie), denn leider weiß man bisher von schwachen Lösungen nur, dass sie eine Energieungleichung erfüllen. Eine zweite Schwierigkeit der INS ist der Zusammenhang zwischen Druck und Divergenzgleichung. Ein Trick der schwachen Theorie ist, dass wir uns von Anfang an auf Funktionen beschränken, die schwach divergenzfrei sind (also die Gleichung in Integralmittel erfüllen. Was in der Theorie sehr gut funktioniert, ist blöd für die Numerik, weil man Divergenzfreiheit immer wieder herstellen muss wegen der Rechenfehler im Prozess. Unter den Forschern gibt es zwei Richtungen: Entweder man sucht nach Blow-up Lösungen, also schwachen Lösungen, die keine punktweisen Lösungen sein können, oder man versucht die Zusatzforderungen aufzuweichen (um sie am Ende ganz weglassen zu können). Dabei gibt es ständig kleine Fortschritte. Es gibt auch zwei Wege, für allgemeinere Modelle Theorien zu entwickeln, die dann im Spezialfall auch etwas über INS sagen. Ein durch O.A. Ladyzenskaya vorgeschlagener Zugang geht über den p-Laplace-Operator. Hier findet man starke Lösungen für alle p>2,5, die INS ist jedoch der Fall p=2. Als Materialgesetz interessant für Ingenieure ist aber der noch schwierigere Fall 1

On today's THE FOOD SEEN, Nathan Myhrvold has always been ambitious, cooking his family a full Thanksgiving dinner at the age of 9, graduating high school at 14, two Masters degrees and a PHD in Theoretical and Mathematical Physics at 23 from Princeton, and postdoctoral cosmology work at the University of Cambridge with Stephen Hawking for more than a brief history of time. But there was something about that cooking process that stuck with him, even through his years at Microsoft as Chief Technology Officer. He asked Bill Gates for a leave of absence to attend cooking school in France, but first he had to stagé at a restaurant 1 day/wk for 2 years to get in. He did that. And kept cooking. And kept questioning why we cooked the way we do. The Cooking Lab was then founded, a place where he could experiment with new techniques, equipment, and ideas … so he wrote a book called “Modernist Cuisine”, a 5 volume, 2000 plus page, 40 lb tome. And if that wasn't enough, he released an “At Home” compendium. And now, “The Photography of Modernist Cuisine” version. But all of this knowledge this just piqued more interest, and made Nathan ask, “why not”. That's where we are today. Of all that we understand about the ever expanding universe, we are still a society of convention when it comes to food. Nathan thinks there's much more to explore. Just see for yourself! This program has been sponsored by Blueprint. “We wanted to show people a vision of food they had never seen before.” [39:25] “Any dish is worthy of your attention, and is worthy of considering at the ultimate level.” [62:45] — Nathan Myhrvold on The Food Seen

This graphic extravaganza from mathematical physicist John Baez shows not only humanity's nested time dimensions but how we expand our time perspective to understand and solve crises. Baez's famed online column, "This Week's Finds in Mathematical Physics," which began in 1993, was an influential pioneer of the blog genre.
