If you've ever wondered which part of physics covers which part of space, fret no more. Here is an awesome map that lays it all out.
One prominent mathematician asks: was Einstein such a smartypants after all?
Einstein's theory of relativity revolutionized our view of the universe, positing a space-time continuum undergirding all reality. Equally impactful has been quantum mechanics, which describe the behavior of subatomic particles in ways that differ from observable matter. But both theories have been verified by empirical observation and scientific experiments. String theory, and a select number of other theories that purport to explain the universe in one, all-encompassing equation, remain completely divorced from the physical world. Surely theories about the universe must relate directly to the matter in it?! Did Einstein get it wrong, or has groupthink led us down the wrong path for the last 40 years? Eric Weinstein basically posits that perhaps Einstein's work shouldn't necessarily be as lauded as it is, in part because Einstein himself said that it is a work in progress (or, in his words, "a mansion with a wing made out of marble and a wing made out of cheap wood"). What does this mean for you? Well, to most of the Joe Schmoe's in this world, not much. But if you're deep into theoretical physics and super advanced mathematics as Eric Weinstein is, you'll probably be hooting and hollering at the screen going "OH SNAP!" and "NO HE DI'NT!" like you're watching an NFL game. String theory... kids love it!
Einstein believed his greatest blunder to have been the retraction of one of his equations but, as writer David Bodanis tells, the great scientist's misstep actually happened immediately after.
David Bodanis is a futurist, business advisor and popular science writer, and when it comes to Einstein, he literally wrote the books – plural. His first was called E=mc2: A Biography of the World's Most Famous Equation, which was translated into 26 languages and turned into a documentary and an award-winning ballet. Now Bodanis goes deeper into the genius’ world with the biography Einstein’s Greatest Mistake.
Bill Nye is always dressed for a party, but this time his celestial bow-tie pays respect to one of our era's greatest discoveries: gravitational waves.
At 4am on September 14, 2015, a team of over 1,000 scientists who form the Laser Interferometer Gravitational-Wave Observatory (LIGO) confirmed an aspect of Albert Einstein's general theory of relativity.
