Music And Math: The Genius of Beethoven

Music And Math: The Genius of Beethoven

How is it that Beethoven, who is celebrated as one of the most significant composers of all time, wrote many of his most beloved songs while going deaf? The answer lies in the math behind his music. Natalya St. Clair employs the “Moonlight Sonata” to illustrate the way Beethoven was able to convey emotion and creativity using the certainty of mathematics.

7 Talks To Make You Love Science

7 Talks To Make You Love Science

Science is about discovering the wonders of how our world works.

From physics to biology to neuroscience, here are seven talks to make you love science.

1. Suicidal crickets, zombie roaches and other parasite tales


We humans set a premium on our own free will and independence … and yet there’s a shadowy influence we might not be considering. As science writer Ed Yong explains in this fascinating, hilarious and disturbing talk, parasites have perfected the art of manipulation to an incredible degree. So are they influencing us? It’s more than likely.


 

2. What is so special about the human brain?

The human brain is puzzling — it is curiously large given the size of our bodies, uses a tremendous amount of energy for its weight and has a bizarrely dense cerebral cortex. But: why? Neuroscientist Suzana Herculano-Houzel puts on her detective’s cap and leads us through this mystery. By making “brain soup,” she arrives at a startling conclusion.


 

3. The weird, wonderful world of bioluminescence

In the deep, dark ocean, many sea creatures make their own light for hunting, mating and self-defense. Bioluminescence expert Edith Widder was one of the first to film this glimmering world. At TED2011, she brings some of her glowing friends onstage, and shows more astonishing footage of glowing undersea life.


 

4. Psychedelic science

Swiss artist and photographer Fabian Oefner is on a mission to make eye-catching art from everyday science. In this charming talk, he shows off some recent psychedelic images, including photographs of crystals as they interact with soundwaves. And, in a live demo, he shows what really happens when you mix paint with magnetic liquid—or when you set fire to whiskey.


 

5. The birds and the bees are just the beginning

Think you know a thing or two about sex? Think again. In this fascinating talk, biologist Carin Bondar lays out the surprising science behind how animals get it on. (This talk describes explicit and aggressive sexual content.)


 

6. Is our universe the only universe?

Is there more than one universe? In this visually rich, action-packed talk, Brian Greene shows how the unanswered questions of physics (starting with a big one: What caused the Big Bang?) have led to the theory that our own universe is just one of many in the “multiverse.”


 

7. Swim with the giant sunfish

Marine biologist Tierney Thys asks us to step into the water to visit the world of the Mola mola, or giant ocean sunfish. Basking, eating jellyfish and getting massages, this behemoth offers clues to life in the open sea.

A Truncated Story of Infinity

In this interesting video find the infinite possibilities within the everyday. Following a day in the life of Vincent, “Subject X” and his many variations that exist throughout the universe.

The story begins to fracture into different threads when he follows a would be lover down the street.

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.
