Lee Smolin is a physicist at the Perimeter Institute who Is a vocal critic of string theory. He is fascinated by quantum gravity, contributing to two major theories, loop quantum gravity and deformed special relativity. He proposed ‘cosmological natural selection’: a falsifiable mechanism to explain the choice of the laws of physics.
He has also contributed to quantum field theory, the foundations of quantum mechanics, theoretical biology, the philosophy of science and economics. He is the author of more than 150 scientific papers and numerous essays and writings for the public on science.
He also has written four books which explore philosophical issues raised by contemporary physics and cosmology. These are Life of the Cosmos (1997), Three Roads to Quantum Gravity (2001), The Trouble with Physics (2006) and Time Reborn (2013). Most recently, he coauthored The Singular Universe and The Reality of Time with Roberto Mangabeira Unger.

#AndyWeir #ProjectHailMary #TheMartian
A lone astronaut must save the earth from disaster in this incredible new science-based thriller from the #1 New York Times bestselling author of The Martian. Andy Weir is a lifelong space nerd and a devoted hobbyist of such subjects as relativistic physics, orbital mechanics, and the history of manned spaceflight.
Ryland Grace is the sole survivor on a desperate, last-chance mission–and if he fails, humanity and the earth itself will perish. Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company.
His crewmates dead, his memories fuzzily returning, he realizes that an impossible task now confronts him. Alone on this tiny ship that’s been cobbled together by every government and space agency on the planet and hurled into the depths of space, it’s up to him to conquer an extinction-level threat to our species.
And thanks to an unexpected ally, he just might have a chance.
Part scientific mystery, part dazzling interstellar journey, Project Hail Mary is a tale of discovery, speculation, and survival to rival The Martian–while taking us to places it never dreamed of going.

Just in time for the holidays, my gift guide shows you how to buy a time-machine for the kid in your life. This gift is a portal to a life of curiosity and wonder that doubles as a teacher, life long hobby, and, potentially, a career!
This wonderful gift transformed me from a nerdy introverted pimple faced kid, to a Professor of physics. It changed my life forever. While my first telescope, obtained in 1984, cost about $50, inflation (not the cosmological kind ?), has taken those costs to over $100! But at least new ones coming with some of these instruments feature tools scarcely imaginable 37 years ago, like ‘smart phone adapters’ and GPS receivers!
So, at the end of the video I’ll give you tips to do the same for a the kid in your life . Get my telescope buyer's guide here: https://briankeating.com/blog.php for a few telescope options for budgets ranging from $50 on up!

#BlackHoles #Wormholes #Interstellar Juan Maldacena joined me to discuss his fascinating new paper on human traversable wormholes and other topics in fundamental physics. Join in the chat to participate! We discussed the Multiverse, Black Holes, Wormholes, SETI, Life on Einstein Lane, Interstellar the Movie, and even God!
We chatted about his recent paper "HUMANLY TRAVERSABLE WORMHOLES" https://arxiv.org/abs/2008.06618 which is based, in part, on this earlier paper: "Traversable wormholes in four dimensions" https://arxiv.org/abs/1807.04726
When you sign up for my newsletter, I'll send you links to download two explanatory talks on these papers. Please join my mailing list; just click here ? http://briankeating.com/mailing_list.php
We also discussed an interesting economic analog to the Higgs Mechanism first elaborated by Dr. Pia Malaney and Dr. Eric Weinstein, explaining gauge theory and electromagnetism. See Juan's paper "The symmetry and simplicity of the laws of physics and the Higgs boson" here: https://arxiv.org/pdf/1410.6753.pdf . You will also enjoy his video lecture based on that paper here: https://www.youtube.com/watch?v=OQF7kkWjVWM

Juan Martín Maldacena (September 10, 1968 in Buenos Aires, Argentina) is a theoretical physicist and the Carl P. Feinberg Professor in the School of Natural Sciences at the Institute for Advanced Study. He has made significant contributions to the foundations of string theory and quantum gravity. His most famous discovery is the AdS/CFT correspondence, a realization of the holographic principle in string theory.

As readers of my newsletter (briankeating.com/list) know, I recently returned from the Simons Observatory where we were commissioning the three small aperture telescope platforms . These are the mounts on which our three half-meter diameter refracting telescopes will be placed to scan the sky for at least five years! This video, made by @helgephilipp5349 demonstrates how the telescope platforms were delivered and assembled and a little bit of what it's like to work at 17,000 feet above sea level!
Original video https://www.youtube.com/watch?v=ujzN7t_wqPk
