TED-Ed: Why are some people left-handed? - Daniel M. Abrams
Today, about one-tenth of the world's population are southpaws. Why are such a small proportion of people left-handed -- and why does the trait exist in the first place? Daniel M. Abrams investigates how the uneven ratio of lefties and...

How To Make MUONS
This video is about how to create muons in a particle accelerator via bombardment of heavy nuclei with protons, which results in creation of charged pions (plus and minus). The pions then decay into muons and mu neutrinos, and the muons...

TED-ED: Can machines read your emotions? - Kostas Karpouzis
Computers can beat us in board games, transcribe speech, and instantly identify almost any object. But will future robots go further by learning to figure out what we're feeling? Kostas Karpouzis imagines a future where machines and the...
