If you're not a physicist, the concept of "quantum" will likely confuse you, or simply put you off. But even for experts, the quantum world can be complex. Luckily, in a world where for nearly every challenge there's a bespoke robot ready to help, an AI now makes it easier to navigate quantum systems too.
Predicting the future is easy, if you are a physicist. Break a glass, and you can boldly assert that it will fall into a number of shards, assuming you know the initial conditions. Knowing the past is more difficult – you need to store much more information to piece a pile of broken glass back together. This "causal asymmetry" makes it easier to determine cause and effect and thus place events in order. But it doesn't exist in the quantum world, say Mile Gu at Nanyang …
This book is a whirlwind survey of more speculative topics– getting well beyond "normal" low-energy quantum physics to talk about black holes and that sort of thing– wrapped up in a personal narrative. This gets into some heavy ideas, but Gefter's voice and enthusiasm for the topic are charming enough to carry it off.
In this photograph taken on Friday, Feb. 26, 2010, clickers are shown in the use of students in the physics class of Professor Michael Dubson at the University of Colorado in Boulder, Colo. One of the two classes I'm teaching this term is our sophomore-level "modern physics" class, which richly deserves its scare quotes. "Modern physics" in an educational context means, essentially, "Physics from 1900-1950." It's a brief introduction to Special Relativity, followed by some introductory quantum physics, and a smattering of applications (solid state, nuclear) as time permits. Some of the examples we use to illustrate key points are modern in the more colloquial sense -- there have been a lot of spectacular basic-quantum-physics experiments in the last 20-ish years -- but the core principles of everything we talk about were locked down in the first half of the previous century.
