What is metallic glass? - Ashwini Bharathula

View full lesson: http://ed.ted.com/lessons/what-is-metallic-glass-ashwini-bharathula Steel and plastic are essential to much of our infrastructure and technology. Steel is strong and hard, but difficult to shape intricately. Plastic can take on just about any form, but it’s weak and soft. Wouldn’t it be nice if there were one material as strong as the strongest steel and as shapeable as plastic? Ashwini Bharathula discusses the future of metallic glass. Lesson by Ashwini Bharathula, animation by Tinmouse Animation Studio.

Human sperm vs. the sperm whale - Aatish Bhatia

View full lesson: http://ed.ted.com/lessons/human-sperm-vs-the-sperm-whale-aatish-bhatia Traveling is extremely arduous for microscopic sperm -- think of a human trying to swim in a pool made of...other humans. We can compare the journey of a sperm to that of a sperm whale by calculating the Reynolds number, a prediction of how fluid will behave, often fluctuating due to size of the swimmer. Aatish Bhatia explores the great (albeit tiny) sperm's journey. Lesson by Aatish Bhatia, animation by Brad Purnell.

Why don't oil and water mix? - John Pollard

View full lesson: http://ed.ted.com/lessons/why-don-t-oil-and-water-mix-john-pollard Salt dissolves in water; oil does not. But why? You can think of that glass of water as a big, bumpin' dance party where the water molecules are always switching dance partners -- and they'd much rather dance with a salt ion. John Pollard explains how two chemistry principles, energetics and entropy, rule the dance floor. Lesson by John Pollard, animation by Andrew Foerster.

What about reading people’s emotions? How healthy are you, compared to other people you know? Knowing how our skills stack up against others is useful in many ways.

Eric Rosado details how gunpowder has caused devastation around the world, despite the incandescent beauty of fireworks. Lesson by Eric Rosado, animation by Zedem Media.
