On Olympus, you’ve been waiting for an opportunity to bring the bloody Trojan War to its conclusion. The two sides have agreed to a brief truce, and when you consult the Fates, they advise: should the peace last for 10 days, all will end soon. But if the truce is broken, there will be 10 more devastating years of war. Can you help the Greeks and Trojans keep the peace? Dennis Shasha shows how.

Lesson by Dennis E. Shasha, directed by Igor Coric, Artrake Studio.

Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our perception. Here is a closer look at the waves we can't see.

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.

Explore the science behind how your body and brain process different sensations like touch, pain, temperature, and spatial awareness.

--

We don’t often think of touch as being a vital part of movement, but touch is one part of a network that oversees all the sensations arising from the surface and interior of our bodies. Touch, pain, temperature, and our spatial awareness are regulated by this system. So, how exactly do our brains process these sensations? And what happens when something goes wrong? Antonio Cataldo investigates.

Lesson by Antonio Cataldo, directed by Yuriy Polyashko, Darvideo Animation Studio.

Over the years, research has shown a counterintuitive fact about human nature: That sometimes, having too much choice makes us less happy. This may even be true when it comes to medical treatment. Baba Shiv shares a fascinating study that measures why choice opens the door to doubt, and suggests that ceding control -- especially on life-or-death decisions -- may be the best thing for us. (Filmed at TEDxStanford.)
