On July 4, 2012, the discovery of the Higgs boson was announced. This was a massive, worldwide media sensation - the Higgs boson is a big deal. Who better to illustrate the importance of this monumental discovery than our very own Sean Carroll? 9MndczV78uw sean-carroll-the-hidden-reality-of-quantum-physics Sean Carroll | The Hidden Reality of Quantum Physics Sean Carroll, the American theoretical physicist who specializes in quantum mechanics, gravity and cosmology explains the hidden reality of the micro-world. hzLTgtFaPLY atomic-clocks-are-reinventing-time Atomic Clocks are Reinventing Time Though humans don't experience it in their daily lives, gravity and movement can change how time elapses. PdL8CudJTcs sabine-hossenfelder-is-time-real Sabine Hossenfelder | Is Time Real? In this video I explain why some physicists argue that time does not exist, and what that even means. Correction: The photo at about 1 mins doesn't show Hermann Minkowski (who is the one I meant) but his brother Oskar. Sorry about that. 5hVmeOCJjOU sean-carroll-a-brief-history-of-quantum-mechanics Sean Carroll | A Brief History of Quantum Mechanics The mysterious world of quantum mechanics has mystified scientists for decades.
