If You Don’t Think This Math Is Interesting … There’s The Door

The folks at Pixar are widely known as some of the world’s best storytellers and animators. They are perhaps less recognized as some of the most innovative math whizzes around. Pixar Research Lead Tony DeRose delves into the math behind the animations, explaining how arithmetic, trigonometry and geometry help bring Woody and the rest of your favorite characters to life.

How Greek Maths Changed the World

How Greek Maths Changed the World

Professor Alan Davies presents a series of groundbreaking experiments pioneered by the Ancient Greeks. Often called the “birthplace of civilisation”, Ancient Greece heralded numerous advances in philosophy, science, engineering and mathematics which have shaped our understanding of the modern world.

Assisted by Ri demo technician, Andy Marmery, Professor Davies demonstrates the key discoveries and experiments of many Greek thinkers — from Thales and Pythagoras to Euclid, Archimedes and Hypatia of Alexandria.

Monty Hall Problem

The Monty Hall Problem is a famous (or rather infamous) probability puzzle. This video features Lisa Goldberg, an adjunct professor in the Department of Statistics at University of California, Berkeley.

The Science Of Symmetry

The Science Of Symmetry

When you hear the word symmetry, you might think generally of triangles, butterflies, or even ballerinas. But defined scientifically, symmetry is “a transformation that leaves an object unchanged.” Huh? Colm Kelleher unpacks this abstract term and explains how animal’s distinct symmetries can tell us more about them — and ourselves.

The Case Of The Missing Fractals

The Case Of The Missing Fractals

A bump on the head, a mysterious femme fatale and a strange encounter on a windswept peak all add up to a heck of a night for Manny Brot, Private Eye. Watch as he tries his hand at saving the dame and getting the cash! Shudder at the mind-bending geometric riddles! Thrill to the stunning solution of The Case of the Missing Fractals.

Lesson by Alex Rosenthal and George Zaidan, animation by TED-Ed.

Poincaré Conjecture

Poincaré Conjecture

The Millennium Prize Problems are seven problems in mathematics that were stated by the Clay Mathematics Institute in 2000. As of July 2013, six of the problems remain unsolved. A correct solution to any of the problems results in a US $1,000,000 prize (sometimes called a Millennium Prize) being awarded by the institute. The Poincaré conjecture was solved by Grigori Perelman, but he declined the award in 2010. [via]
