They’re millions of digits long, and it takes an army of mathematicians and machines to hunt them down — what’s not to love about monster primes? Adam Spencer, comedian and lifelong math geek, shares his passion for these odd numbers, and for the mysterious magic of math.

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.
Robot traders are dominating stock markets using high speed computer algorithms. Human traders and government regulators canât keep up, and markets could be one programming glitch away from the next big crash. Stan Correy investigates.
Melvyn Bragg and guests discuss random and pseudorandom numbers. Randomness will be familiar to anybody who’s bought a lottery ticket or shuffled a pack of cards. But there’s also a phenomenon known as pseudo-randomness –numbers which look random but aren’t. So why are these numbers useful and how can they be generated? Melvyn is joined by Marcus du Sautoy, Professor of Mathematics at the University of Oxford; Colva Roney-Dougal, Senior Lecturer in Pure Mathematics at the University of St Andrews; and Timothy Gowers, Royal Society Research Professor in Mathematics at the University of Cambridge.
The guys sit down with Danica McKellar for a stellar conversation about growing up Winnie Cooper, her passion for math and how to give children confidence through education. Danica is WAY smart. She has a theorem named after her for crapsake! This ep takes wonderful turns that you may not expect!
Today, Charles Babbage writes a letter to Alfred Lord Tennyson. The University of Houston’s College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them.
When writing the Principia Mathematica, Isaac Newton declared his hand on most of the big questions in physics. He outlined the nature of space, explained the motions of the planets and conceived the operation of gravity. He also laid down the law on time declaring:
“Absolute, true, and mathematical time, of itself and from its own nature, flows equably without relation to anything external.”
For Newton time was absolute and set apart from the universe, but with the theories of Albert Einstein time became more complicated; it could be squeezed and distorted and was different in different places.
Time is integral to our experience of things but we find it very difficult to think about. It may not even exist and yet seems written into the existence of absolutely everything.

The man who calculated as other men breathe. Professor Marcus du Sautoy on the mathematical omnivore without whom no history of mathematics is complete.
The battle over the calculus. Professor Marcus du Sautoy reveals how the great hero of British science is rather less gentlemanly than his German rival. An astronaut and investment analyst pay homage to the enormous power of the calculus.
