As a grad student, Priya Natarajan theorized that winds emanate from black holes, affecting nearby stars. Now, new evidence hints that she was right.
In The Joy of X: A Guided Tour of Math, from One to Infinity, mathematician Steven Strogatz provides an entertaining refresher course in math, starting with the most elementary ideas, such as counting, and finishing with mind-bending theories of infinity—including the idea that some infinities can be bigger than others.
Black Holes seem to have bad press that is largely undeserved. This lecture with professor Ian Morison explains what Black Holes are, and how we can discover them even through they can’t be seen.
This program was recorded in collaboration with Gresham College, on October 27, 2010.
Gresham Professor of Astronomy Ian Morison made his first telescope at the age of 12 with lenses given to him by his optician. Having studied Physics, Maths and Astronomy at Oxford, he became a radio astronomer at the Jodrell Bank Observatory and teaches Astronomy and Cosmology at the University of Manchester.
Over 25 years he has also taught Observational Astronomy to many hundreds of adult students in the North West of England. An active amateur optical astronomer, he is a council member and past president of the Society for Popular Astronomy in the United Kingdom.
At Jodrell Bank he was a designer of the 217 KM MERLIN array and has coordinated the Project Phoenix SETI Observations using the Lovell Radio Telescope. He contributes astronomy articles and reviews for New Scientist and Astronomy Now, and produces a monthly sky guide on the Observatory’s website.
Steven S. Gubser and Frans Pretorius are professors of physics at Princeton University. Their new book, "The Little Book of Black Holes" takes readers deep into the mysterious heart of the subject offering rare clarity of insight into the physics that makes black holes simple yet destructive manifestations of geometric destiny.
Ever since Einstein’s general theory of relativity predicted their existence more than a century ago, black holes have intrigued scientists, writers, and the general public with their bizarre and fantastical properties. And the physics governing their behavior is stranger and more mind-bending than any fiction. Gubser and Pretorius illuminate black holes as astrophysical objects and theoretical “laboratories” in which researchers can test their understanding of physics.

How Black Holes Work —It wasn’t too long ago when black holes were strictly predictions in theoretical math. Over decades, astronomy has gotten better at uncovering these cosmic phenomena. Learn about how black holes form and their ability to spaghettify you in this episode.
We’re finally ready to deal with the topic you’ve all been waiting for: Schwarzschild swirlers, Chandrasekhar crushers, ol’ matter manglers, sucking singularities… you might know them as black holes. Join as as we examine how black holes form, what they consume, and just how massive they can get.
The acclaimed mathematician and author Steven Strogatz interviews some of the world’s leading scientists about their lives and work.
Steven Strogatz has a really impressive resumé. Besides being a professor at Cornell, he also has the sixth most highly cited paper in all of physics and his 1998 paper “Collective dynamics of small-world networks” was the most highly cited paper in its field for a decade. Cool as all of that is that’s not what excites us most about Steven Strogatz, because as you look at his resumé you realize that Strogatz is perhaps the greatest living popularizer of something that underpins all of our lives but most people have (at best) mixed feelings about: math. As the author of a series of NY Times columns that the Harvard Business Review “must reads for entrepreneurs and executives who grasp that mathematics is now the lingua franca of serious business analysis.” Those columns have now been collected in an awesome book called The Joy of X: A Guided Tour of Math From One to Infinity. From basic arithmetic to calculus and beyond, Strogatz shows readers not just what math is but puts it in a context that allows us to experience the beauty of math regardless of how much math we actually know. In this interview, Professor Strogatz discusses his book and gives Bryan and Hunter an inside look at the life of a top-level mathematician. They discuss math prodigies, cultural beliefs at math and the importance of constantly striving for excellence every day even if you’re not sure it’ll pay necessarily pay off. This conversation will not only teach you the Joy of X; it will teach you the Joy of Talking to Professor Strogatz.
Steven Strogatz is the author of three books: The Calculus of Friendship, Sync and The Joy of X. They’re all available at Amazon and everywhere else. Also, check out his awesome TED talk about how flocks of birds and other animals sync up: http://www.ted.com/talks/steven_strogatz_on_sync.html

Steven Strogatz: The Joy of X — Did you know some infinities are bigger than others? Or that one is equal to .99999999999 repeating? Just a few of the math mysteries in The Joy of X, a new book by Steven Strogatz.

Krista Tippett, host: All of reality is interaction. This everyday truth is as scientific as it is philosophical and political, and it unfolds with unexpected nuance in Carlo Rovelli’s science. He’s the author of the global bestseller Seven Brief Lessons on Physics. This tiny book is, in my mind, the science writing equivalent of moving from prose to poetry. He’s taken up vast ideas beyond most of our imagining — like quanta, grains of space, and time and the heat of black holes. He’s condensed them into spare, beautiful words that render them newly explicable and moving.
