Podcast appearances and mentions of nima arkani hamed

Happy New Year 2025! To celebrate, here is an encore of what proved to be the most popular episode of 2024. This rerun combines episodes 30 and 31 into one epic journey towards the frontiers of human understanding. My guest is Donald Hoffman. Our topics are consciousness, cosmos, and the meaning of life. Enjoy! Original show notes Laws of physics govern the world. They explain the movements of planets, oceans, and cells in our bodies. But can they ever explain the feelings and meanings of our mental lives? This problem, called the hard problem of consciousness, runs very deep. No satisfactory explanation exists. But many think that there must, in principle, be an explanation. A minority of thinkers disagree. According to these thinkers, we will never be able to explain mind in terms of matter. We will, instead, explain matter in terms of mind. I explored this position in some detail in episode 17. But hold on, you might say. Is this not contradicted by the success of natural sciences? How could a mind-first philosophy ever explain the success of particle physics? Or more generally, wouldn't any scientist laugh at the idea that mind is more fundamental than matter? No — not all of them laugh. Some take it very seriously. Donald Hoffman is one such scientist. Originally working with computer vision at MIT's famous Artificial Intelligence Lab, Hoffman started asking a simple question: What does it mean to "see" the world? His answer begins from a simple idea: perception simplifies the world – a lot. But what is the real world like? What is “there” before our perception simplifies the world? Nothing familiar, Hoffman claims. No matter. No objects. Not even a three-dimensional space. And no time. There is just consciousness. This is a wild idea. But it is a surprisingly precise idea. It is so precise, in fact, that Hoffman's team can derive basic findings in particle physics from their theory.  A fascinating conversation was guaranteed. I hope you enjoy it.

In the music of Derek Bermel, familiar oppositions – between classical and vernacular, comic and serious, visceral and cerebral – start to break down. In Intonations (2016) for string quartet, a series of ragged chords, like the sound of someone blowing idly on a harmonica, is taken apart, reassembled, and woven into a web of dazzlingly ornate counterpoint. In A Short History of the Universe (as related by Nima Arkani-Hamed) (2013), a raucous, jazzy glissando becomes the unlikely basis of meditation on cosmology and the nature of time. The music on this album is full of such moments of strange alchemy, in which seemingly antithetical qualities merge and transform each other unpredictably.Purchase the music (without talk) at:Derek Bermel (classicalsavings.com)Your purchase helps to support our show! Classical Music Discoveries is sponsored by La Musica International Chamber Music Festival and Uber. @CMDHedgecock#ClassicalMusicDiscoveries #KeepClassicalMusicAlive#LaMusicaFestival #CMDGrandOperaCompanyofVenice #CMDParisPhilharmonicinOrléans#CMDGermanOperaCompanyofBerlin#CMDGrandOperaCompanyofBarcelonaSpain#ClassicalMusicLivesOn#Uber Please consider supporting our show, thank you!http://www.classicalsavings.com/donate.html staff@classicalmusicdiscoveries.com This album is broadcasted with the permission of Crossover Media Music Promotion (Zachary Swanson and Amanda Bloom).

It's been described as one of the most remarkable collections of minds on the planet. It has a brilliant international faculty, but no students. Its researchers have made some of the most significant scientific discoveries of the 20th century, but it has never had a laboratory. Sally Marlow joins scholars for the start of a new term at The Institute for Advanced Study, Princeton New Jersey, conceived as a paradise for curiosity-driven research in mathematics, natural sciences, social science and history. The Institute has more than once been called an Intellectual Hotel, and that certainly captures its leisurely pace, but appearances can be deceptive. Scholars here have an extraordinary ability to work on what everyone else is looking at, but to see something differently. Since its founding in 1930, it's been home to a remarkable number of world-class thinkers, the most famous of whom was Albert Einstein who exerted a gravitational pull on attracting many scientists of promise to the Institute. From John von Neumann, widely credited with inventing the programmable computer, to J. Robert Oppenheimer, lead architect of the atomic bomb, to the surprise arrival of poet and playwright T.S. Eliot - the Institute's first Artist in Residence, Sally Marlow gets beneath the skin of some of its rich history and its extraordinary ethos, wondering how the weight of the past plays out on those bright minds there today. As a scholar herself at the Institute of Psychiatry, Psychology and Neuroscience, King's College London, Sally knows that space and time to think is becoming increasingly challenged, So what happens when you turn thinkers loose from the constraints of a traditional academic institution? And amidst the Institute's hotbed of string theorists, she seeks answers to Einstein's biggest, most tantalising question of all - whether there's a grand, all-embracing theory, a unified theory of everything, that will complete our understanding of the laws of the universe. Featuring interviews with Robbert Dijkgraaf, Director of the IAS, Myles Jackson, Professor of History of Science, Joan Scott Professor Emerita in the School of Social Science, particle physicist Nima Arkani-Hamed, Freeman Dyson, retired theoretical physicist , historian George Dyson , Christina Sormani, Professor of Maths at City University New York, archivist Casey Westerman and composer and former artist in residence Derek Bermel.

Nima Arkani-Hamed is championing a campaign to build the world’s largest particle collider, even as he pursues a new vision of the laws of nature.

Women of science London's Royal Society was buzzing last week as historians and scientists chewed over the lives of iconic women scientists. But at a time when far more women go into science, the percentage who make it to professor is still alarmingly low compared to men. Last week's Revealing Lives event by The Royal Society was also about learning lessons from history which are of benefit to women working in science today. Mapping the ocean floor We really do know less about the ocean floor on Earth than we do about the surface of Mars, Venus and the Moon. In the case of the Red Planet, the maps are about 250 times better. This gap in our home-planet knowledge has recently been highlighted by the search for the missing Malaysia airlines plane MH370. The suspected search area in a remote part of the Indian Ocean is so poorly mapped, it's not even clear how deep the deepest parts are. Ocean floor mapping can be done by ship board echo-sounders, bouncing sound waves off the sea floor. But this is very expensive. A new cheaper, quicker way is to use a satellite to measure fluctuations in the sea surface caused by gravitational perturbations caused by underwater topography. Longitude Challenge 2014 - Food security By 2050 there will be an estimated 9.1 billion people on the planet. In the face of limited resources and climate change, how can we feed the world with less? Michael Moseley thinks eating insects is a start whilst Marnie Chesterton checks out a field of self-fertilising crops. And the issue that it's not always the amount of food, but the right food is highlighted in a report from the Metropolitan Manila area of the Philippines where a portion of fries and a burger is cheaper than a kilo of carrots. Amplituhedron Particle physicists have discovered a mysterious jewel-like object that exists in higher dimensions in mathematical space. This multifaceted object, The Amplituhedron, greatly simplifies the complex calculations that explain what happens during particle collisions - the kind of collisions studied at particle accelerators, like the Large Hadron Collider. No one's entirely sure exactly what this object is, or how important it might turn out to be - there's some suggestion it may challenge the very notion that space-time is a fundamental property of our universe. Joel Werner caught up with the man who discovered this jewel, Nima Arkani-Hamed, at the Institute for Advanced Study in the United States to try and unravel exactly what this mysterious object is. Producer: Fiona Roberts.

Nima Arkani-Hamed on the Large Hadron Collider and the Future of Fundamental Physics. Located on the Swiss-French border, the Large Hadron Collider is a circular tunnel 27 km in circumference. It will allow physicists to probe the constituent parts of the proton, looking for new forms of matter and insights into the formation of the universe.

Nima Arkani-Hamed presents a new approach to quantum field theory that relies on dualities to avoid Feynman graphs.

Nima Arkani-Hamed discusses how fundamental physics started the 20th century with the twin revolutions of relativity and quantum mechanics, and much of the second half of the century was devoted to the construction of a theoretical structure unifying these radical ideas, which has been confirmed to exquisite precision by experiments over the past three decades.
