Learn about Einstein’s life in Princeton including his work at the Institute for Advanced Study; his humor and philosophy; his home life; and more.

The existence of atoms was not yet proven in 1905 when Einstein proposed that random movements in water were atoms colliding. See how they behave at different temperatures down to several hundred billionths of a degree above absolute zero.

Project your face onto a pair of manikins to create two selves. Send one to travel at 95% of the speed of light. After 100 years, how does your space self look compared to the Earth-bound version?

Calculate how much energy your body’s atoms contain. Spoiler alert – it’s a HUGE number!

Einstein called it “spooky action at a distance” and could never accept the idea, but quantum entanglement is real. To win this game, you must first entangle your particles, then compete to win. Can you figure out what to do?

Explore the discovery for which Einstein received the 1922 Nobel Prize. Adjust wavelengths and metals to see how the effect changes.
