![]() In contrast, every quantum object has one feature: a wave function defined by Schrödinger’s 1926 equation, which explains what happens when one measures it. Everything is transparent whatever happens to that object is explained by classical laws of physics-essentially Newton’s. He begins by pointing out that in our everyday world, the world of classical mechanics, every object has two features: a location and a velocity. ![]() Carroll swims against the tide, explaining several theories that attempt to describe what is happening, with an emphasis on his favorite, the many-worlds theory. It’s just physics.” This doesn’t bother most physicists, who belong to the shut-up-and-calculate school, and searching for a deep meaning is unfashionable. ![]() ![]() “Quantum mechanics,” he writes, “is unique among physical theories in drawing an apparent distinction between what we see and what really is….If we free our minds from certain old-fashioned and intuitive ways of thinking, we find that quantum mechanics isn’t hopelessly mystical or inexplicable. ![]() However, Carroll (Theoretical Physics/Caltech The Big Picture: On the Origins of Life, Meaning, and the Universe Itself, 2016, etc.) works hard-and somewhat successfully-to deliver an accessible explanation. The latest attempt to describe the “holy grail of modern physics.”Īlthough in theory it works brilliantly, no one fully understands quantum mechanics. ![]()
