Physicists have built a real-number version of quantum mechanics that makes all the same predictions as the standard theory, ...

Quantum mechanics has long relied on complex numbers to describe the strange behavior of particles, from tunneling to ...

Complex numbers seem to have an almost mystical aura surrounding them. Perhaps it’s because of the terminology used for them – for example, they have a ‘real part’ and an ‘imaginary part’, and they ...
