Einstein himself did not create the atomic bomb or even work on the Manhattan Project (he was denied the security clearance by the U.S. Army, which looked askance at his left-leaning politics). But both Einstein’s letters to then-U.S. President Franklin D. Roosevelt outlining the theory of a uran...

More than two decades after publishing his Special Theory of Relativity, Albert Einstein co-invented a refrigerator (with his former student Leo Szilard) that operated on compressed gases. Einstein was moved to create the device after reading about a Berlin family killed by toxic fumes from their...

Einstein was supposedly slow to talk—the man himself told his biographer he didn’t start speaking until at least age three. Stanford economist Dr. Thomas Sowell even coined the controversial term “Einstein Syndrome” to describe exceptionally bright people whose speech is delayed.

Einstein loved to smoke. In 1950, after accepting a life membership in the Montreal Pipe Smokers Club, Einstein said he believed “that pipe smoking contributes to a somewhat calm and objective judgment in all human affairs.”

Part of Einstein’s charm was his disheveled look. In addition to his uncombed hair, one of Einstein’s peculiar habits was to never wear socks. To Einstein, socks were a pain because they often would get holes in them.

Einstein, age 73, declined the offer. In his official letter of refusal, Einstein stated that he lacke...

Einstein loved sailing, even though he wasn’t very good at it—his neighbors on Long Island frequently had to help him right his capsized boat Tinef (Yiddish for “worthless”). And even though Einstein never learned to swim, he kept sailing as a hobby throughout his life.
