by Michael Goldman figures by Michael Gerhardt LIGO’s observation of gravitational waves was perhaps the most stunning physics discovery of the past several years. Two black holes, each 20 to 30 times as massive as the sun, collided in an event of…

Image from New Scientist illustrating the Delft experimental setup Quantum mechanics is so mind-boggling that it has stumped even the greatest minds. In particular, Albert Einstein was so bothered by quantum mechanics that he never gave up in his…
