A cyclotron is a type of particle accelerator. It uses magnetic and electric fields to speed up charged particles like protons or ions to very high speeds. This allows the particles to collide with ...

The wave-particle duality is one of those essential pillars. Physics courses devote weeks to just introducing it – but there are still important aspects that can be covered in a short article.
