Welcome to the November 2022 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy!Support Mindscape on Patreon.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

People have a complicated relationship to mathematics. We all use it in our everyday lives, from calculating a tip at a restaurant to estimating the probability of some future event. But many people find the subject intimidating, if not off-putting. John Allen Paulos has long been working to make mathematics more approachable and encourage people to become more numerate. We talk about how people think about math, what kinds of math they should know, and the role of stories and narrative to make math come alive. Support Mindscape on Patreon.John Allen Paulos received his Ph.D. in mathematics from the University of Wisconsin, Madison. He is currently a professor of mathematics at Temple University. He s a bestselling author, and frequent contributor to publications such as ABCNews.com, the Guardian, and Scientific American. Among his awards are the Science Communication award from the American Association for the Advancement of Science and the Mathematics Communication Award from the Joint Policy Board of Mathematics. His new book is Who’s Counting? Uniting Numbers and Narratives with Stories from Pop Culture, Puzzles, Politics, and More.Web pageWikipediaAmazon author pageTwitterSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

The founders of statistical mechanics in the 19th century faced an uphill battle to convince their fellow physicists that the laws of thermodynamics could be derived from the random motions of microscopic atoms. This insight turns out to be even more important than they realized: the emergence of patterns characterizing our macroscopic world relies crucially on the increase of entropy over time. Barry Loewer has (in collaboration with David Albert) been developing a theory of the Mentaculus — the probability map of the world — that connects microscopic physics to time, causation, and other familiar features of our experience.Support Mindscape on Patreon.Barry Loewer received his Ph.D. in philosophy from Stanford University.

It’s a big universe we live in, so it comes as no surprise that big numbers are needed to describe it. There are roughly 10^22 stars in the observable universe, and about 10^88 particles altogether. But these numbers are nothing compared to some of the truly ginormous quantities that mathematicians have found to talk about, with inscrutable names like Graham’s Number and TREE(3). Could such immense numbers have any meaningful relationship with the physical world? In his recent book Fantastic Numbers and Where to Find Them, theoretical physicist Antonio Padilla explores both our actual universe and the abstract world of immense numbers, and finds surprising connections between them.Support Mindscape on Patreon.Antonio (Tony) Padilla received his Ph.D. in physics from the University of Durham.

With communication satellites, weather satellites, GPS, and much more, what happens in space is already important to our lives here on Earth. And the importance of space is only going to grow as we increase the presence of humans, whether in Earth orbit or beyond. So the questions of what laws govern activity in space, and how nations and institutions should practice good governance more generally, are becoming increasingly urgent. Timiebi Aganaba is an academic and space lawyer who has experience experience in a wide variety of context and countries. We talk about the current status of space law and how to guarantee good governance going forward.Support Mindscape on Patreon.Timiebi Aganaba received Ph.D. and LL.M. degrees from the Institute of Air and Space Law at McGill University.

The detection of gravitational waves from inspiraling black holes by the LIGO and Virgo collaborations was rightly celebrated as a landmark achievement in physics and astronomy. But ultra-precise ground-based observatories aren’t the only way to detect gravitational waves; we can also search for their imprints on the timing of signals from pulsars scattered throughout our galaxy. Chiara Mingarelli is a member of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration, which uses pulsar timing to study the universe using gravitational waves.Support Mindscape on Patreon.Chiara Mingarelli received her Ph.D. in physics from the University of Birmingham. She is currently an assistant professor of physics at the University of Connecticut and a research scientist at the Flatiron Institute Center for Computational Astrophysics.

My little pandemic-lockdown contribution to the world was a series of videos called The Biggest Ideas in the Universe. The idea was to explain physics in a pedagogical way, concentrating on established ideas rather than speculations, with the twist that I tried to include and explain any equations that seemed useful, even though no prior mathematical knowledge was presumed. I’m in the process of writing a series of three books inspired by those videos, and the first one is coming out now: The Biggest Ideas In The Universe: Space, Time, and Motion. For this solo episode I go through one of the highlights from the book: explaining the mathematical and physical basis of Einstein’s equation of general relativity, relating mass and energy to the curvature of spacetime.
