Quantum physics is a very strange thing. She claims that one particle can be in two places at the same time. Moreover, a particle is also a wave, and everything that happens in the quantum world can be represented as an interaction of waves - or particles, as you prefer. All this was clear by the end of the 1920s. During this time, many different more or less convincing interpretations have been tried. Renowned science popularizer John Gribbin takes us on an exciting journey through the "big six" of such explanations, from the Copenhagen interpretation to the idea of a plurality of worlds. All of these options are insane to varying degrees, but in the quantum world, insanity does not equate to fallibility, and being crazier than others does not necessarily mean being more wrong. Six Impossibles is a strikingly concise guide to a truly amazing world.
