As a boy in New York City, Robert Sapolsky, PhD, dreamed of living inside the African dioramas in the Museum of Natural History. By the age of 21, he made it to Africa and joined a troop of baboons. He chose to live with the baboons because they are perfect for learning about stress and stress-related diseases in humans.
Sapolsky is a MacArthur “Genius” Fellow, a professor of biology and neurology at Stanford University, and a research associate with the Institute of Primate Research at the National Museum of Kenya. In 2008, National Geographic and PBS aired an hour-long special on stress featuring Sapolsky and his research on the subject. In addition to Why Zebras Don’t Get Ulcers, Sapolsky has written three other books, including The Trouble with Testosterone, A Primate’s Memoir and Monkeyluv and Other Essays on our Lives as Animals.

Feynmanmrtp2018-06-17 | Elementary Particles and the Laws of Physics
The 1986 Dirac Memorial Lectures
Developing a theory that seamlessly combines relativity and quantum mechanics, the most important conceptual breakthroughs in twentieth century physics, has proved to be a difficult and ongoing challenge. This book details how two distinguished physicists and Nobel laureates have explored this theme in two lectures given in Cambridge, England, in 1986 to commemorate the famous British physicist Paul Dirac. Given for nonspecialists and undergraduates, the talks transcribed in Elementary Particles and the Laws of Physics focus on the fundamental problems of physics and the present state of our knowledge. Professor Feynman examines the nature of antiparticles, and in particular the relationship between quantum spin and statistics. Professor Weinberg speculates on how Einstein's theory of gravitation might be reconciled with quantum theory in the final law of physics. Highly accessible, deeply thought provoking, this book will appeal to all those interested in the development of modern physics.Quantum Complexity - Leonard Susskindmrtp2018-06-03 | Lecture on quantum complexity and uncomplexity by Leonard Susskind given at the Kavli Institute for Theoretical Physics

Abstract: The FRW/CFT duality is a conjectured duality for Friedmann-Robertson-Walker models inspired by the AdS/CFT correspondence. It assumes that the cosmological constant is exactly zero, which is only the case for models with exact unbroken supersymmetry. Because the energy density does not approach zero as we approach spatial infinity, the metric is not asymptotically flat. This is not an asymptotically cold solution.

Ideas are gradually beginning to take shape on how concepts like holography (and other deep insights uncovered in the past two decades) may lead to new fundamental principles for cosmology. Undoubtedly new insights will emerge on long-standing fundamental issues in cosmology: the nature of the big-bang, the initial conditions and fate of the universe. However, these new approaches will most likely lead us in new directions and allow us to formulate the "right" questions. This informal workshop will bring together leading researchers working in cosmology, string theory and quantum gravity to exchange ideas on recent progress and discuss promising future directions.Holographic Cosmology with Leonard Susskind - part 1mrtp2015-08-26 | NOTE: Audio clears up at the 8:20 mark

Sigmund Freud introduces his notorious concept of the “Todestrieb”, the “death drive” in his famous essay “Jenseits des Lustprinzips” (“Beyond the Pleasure Principle”) of 1920. This text has intrigued and puzzled many readers as it relates the death drive to both the so-called “Nirvana principle” aiming at a state without tension and the repetition compulsion, the almost mechanical kernel of the drive itself. If Freud’s death drive stands here philosophically between negation (Schopenhauer) and affirmation (Nietzsche) of the will, Slavoj Žižek insists that we should not confuse the death drive with the craving for self-annihilation, for the return to the inorganic absence of any life-tension. As his Parallax View states, the death drive is, on the contrary, “the very opposite of dying – a name for the 'undead' eternal life itself, for the horrible fate of being caught in the endless repetitive cycle of wandering around in guilt and pain.” In Žižek’s Lacanian reading, the (death) drive represents a 'diabolic' dimension of human beings in opposition to a desire for the lost object that would overcome all differences and tensions. Its articulation as a philosophical concept is certain to lead us also to a deeper understanding of the concept of tension.
Slavoj Žižek is Professor in the Department of Philosophy, University of Ljubljana, Slovenia, and member of the Slovenian Academy of Sciences and Arts. He has gained wide recognition with his characteristic combination of high and low, of Lacanian theory, pop cultural issues and Post-Marxism. He has published a high number of books, edited several collections, and published numerous philosophical and political articles.Black Hole wars - Leonard Susskindmrtp2015-08-09 | The Black Hole Wars Speaker(s): Leonard Susskind Abstract: The strange paradoxes and puzzles of the quantum behaviour of black holes and the things that fall into them led to a spirited battle of ideas between Stephen Hawking, Leonard Susskind and other scientists.

---- Mathematics has proven to be "unreasonably effective" in understanding nature. The fundamental laws of physics can be captured in beautiful formulae. In this lecture I want to argue for the reverse effect: Nature is an important source of inspiration for mathematics, even of the purest kind. In recent years ideas from quantum field theory, elementary particles physics and string theory have completely transformed mathematics, leading to solutions of deep problems, suggesting new in-variants in geometry and topology, and, perhaps most importantly, putting modern mathematical ideas in a `natural’ context.Leonard Susskind - Phases of eternal inflationmrtp2015-05-29 | Date: 15/06/2010 - 5:15 pm Collection: Cosmological Frontiers in Fundamental Physics - 2010Richard Feynman - The World from another point of viewmrtp2015-05-29 | The famous American physicist Richard Feynman used to take holidays in England.

Colloquium given by Leonard Susskind on Sep/9/2009 at The Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Canada.
Abstract: The Standard model of Cosmology consists of a package of ideas that include Cold Dark Matter, Inflation, and the existence of a small Cosmological Constant. While there is no consensus about what lies beyond the Standard Model, there is a leading candidate that also includes a small package of ideas: A Landscape of connected vacua: the idea that the universe started out with a large energy density, and Coleman DeLuccia Tunneling between vacua. An additional idea that comes from string theory and black hole physics is the Holographic Principle. I will explain how the various ingredients for a "post-standard-model" standard model fit together.Leonard Susskind Radio Interview-From String theory to The Holographic Principlemrtp2015-04-16 | Radio interview conducted on April 7, 2013 with Leonard Susskind, Felix Bloch Professor of Theoretical physics at Stanford University and director of the Stanford Institute for Theoretical Physics.Leonard Susskind - PSI Lecture Specialmrtp2014-12-22 | Perimeter Institute talk for PSI by Leonard Susskind on Coleman De-Luccia instantons and how infinite universes get produced inside De Sitter space.

Speaker(s): Leonard Susskind, Sir Anthony Leggett, Christopher Fuchs, Seth Lloyd, Bob McDonald
Do ideas about information and reality inspire fruitful new approaches to the hardest problems of modern physics? What can we learn about the paradoxes of quantum mechanics, the beginning of the universe and our understanding of black holes by thinking about the very essence of information? The answers to these questions are surprising and enlightening, but also controversial. The topic of information within physics has involved some of the 20th century\'s greatest scientists in long-running intellectual battles that continue to the present day. In this special debate, hosted by the CBC\'s Bob McDonald of \'Quirks and Quarks\', you will enjoy a lively discussion between four prominent physicists who have thought long and hard about these questions. information, quantum mechanics, quantum cryptology, entropy, everything computes, properties equals information, uncertainty principle, quantum computer, hologram, black hole, event horizon, coherence, Schrodinger, interference and predictability, quantum state, teleportation, entanglementThe Mark Steel Lectures - Isaac Newtonmrtp2013-04-15 | NOTE: Audio is disabled from 0:03 - 0:36.
