After Nature

In 36 lectures, you'll discover the intricate relationship between mathematics and nature, get a pointed introduction to the language mathematicians use to study shapes and dimensions, and learn how to finally make sense of this abstract—yet undeniably intriguing—subject. And it's all brought to you by award-winning Professor Satyan L. Devadoss of Williams College, a dynamic instructor with an abiding and contagious passion for the worlds of geometry and topology. His clear and engaging presentation style, accompanied with eye-catching animations and graphics, will make your journey into the world of shapes both insightful and unforgettable.

Evidence for the birth of the universe is raining down on you. It's called the cosmic microwave background, and it's had quite a journey. Born in the stupendous annihilation of matter and antimatter seconds after the big bang, trapped in the hot plasma of the expanding universe for 380,000 years, and then suddenly released when the universe cooled to the point that atoms could form, this echo of creation has been on an uninterrupted voyage through space for 13.7 billion years-until it reached you.
