#einstein #relativity #gravity In 1911, a relatively unknown physicist named Albert Einstein published his preliminary theory of gravity. But it hadn't been tested. To do that, he needed a photograph of starlight as it passed the sun during a total solar eclipse. So began a nearly decade-long quest by seven determined astronomers from observatories in four countries, who traveled the world during five eclipses to capture the elusive sight. Over the years, they faced thunderstorms, the ravages of a world war, lost equipment, and local superstitions. Finally, in May of 1919, British expeditions to northern Brazil and the island of Príncipe managed to photograph the stars, confirming Einstein's theory. Sylvester James (Jim) Gates Jr. is an American theoretical physicist. He currently holds the Clark Leadership Chair in Science with the physics department at the University of Maryland College of Computer, Mathematical, and Natural Sciences. He is also affiliated with the University Maryland's School of Public Policy. He served on former President Barack Obama's Council of Advisors on Science and Technology. An excerpt from his book, Proving Einstein Right: The Daring Expeditions that Changed How We Look at the Universe- At its heart, this is a story of frustration, faith, and ultimate victory--and of the scientists whose efforts helped build the framework for the big bang theory, catapulted Einstein to international fame, and shook the foundation of physics.

Welcome to conversations with the brightest minds in the universe...including YOURS! I'm creating the FREE university, taught by the world's most brilliant educators. Best of all, you can attend in your pajamas, there's no homework, and you won't incur any student loan debt! I am the Chancellor's Distinguished Professor of Physics at UC San Diego where my team & I study the origin & evolution of space, time, & matter. I believe scientists are obligated to explain their work in simple terms to non-experts. I think scientifically and I want you to too. Every week I put out two videos: Each Tuesday I bring you a long-form interview with important thinkers, scientists, billionaires and other brainiacs. On Thursdays I present what I call "Thirty Minute Thesis™ Fascinating Deep-dives into physics & cosmology. I wrote INTO THE IMPOSSIBLE & LOSING THE NOBEL PRIZE which was a Best Science Book at Science Friday, Amazon, Science News, Physics Today, Forbes, & Symmetry Magazine., named one of the best cosmology books of all time. I'm on a mission to magnify curiosity, stoke imagination, & inspire minds of all ages. Join me, because, as Sir Arthur C. Clarke said "The only way to discover the limits of the possible is to go beyond them: into the impossible!" ? Watch my most popular videos:?
