Stephen Hawking once sent his PhD student away with a very hard problem – finding exact rotating black hole solutions of Einstein’s equations with a cosmological constant – and was stunned when he came back a few days later with the solution

I was a student of Stephen Hawking’s – here’s what he taught me Like many students of my generation, Stephen Hawking had already had enormous influence on me long before we ever met. When I was hesitating about my A-level choices, it was his book A Brief History of Time that convinced me to continue …

Meet Richard Feynman who taught himself trigonometry, advanced algebra, infinite series, analytic geometry, and both differential and integral calculus at the age of 15. Later he jokingly Cracked the Safes with Atomic Secrets at Los Alamos by trying numbers he thought a physicist might use.

Richard Feynman “Feynman” redirects here. For other uses, see Feynman (disambiguation). Richard Phillips Feynman (/ˈfaɪnmən/; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as …

Timeless physics is the controversial view that time, as we perceive it, does not exist as anything other than an illusion. Arguably we have no evidence of the past other than our memory of it, and no evidence of the future other than our belief in it.

Julian Barbour Julian Barbour (/ˈbɑːrbər/; born 1937) is a British physicist with research interests in quantum gravity and the history of science. Since receiving his PhD degree on the foundations of Einstein’s general theory of relativity at the University of Cologne in 1968, Barbour has supported himself and his family without an academic position, working …

Physicist Nikola Tesla once paid an overdue hotel bill with a box containing a working model of his ‘death beam‘, warning employees never to open it because of the danger. They hid the box & when it was discovered years later & opened, found to contain old (harmless) electrial parts.

In the years following the tragedy, Tesla (the son and grandson of Serbian Orthodox priests) began seeing visions of the air around him “filled with tongues of living flame.” As an adolescent Tesla learned to exercise his willpower to control the visions, but in later life he would spend much of his time feeding and, …
