  Bosons and fermions behave quite differently. It is impossible for two fermions to ever be in the same sate: that’s why electrons in atom must have different orbits and not stay all in the lower-energy one which, in turn, … Read More

Guess the Boson

Ever wondered why two positive charges repel each other? It turns out that tiny particles called bosons are responsible for that. Each positively charged particle is constantly giving off photons, which are the particles that make up light: when one of those … Read More
