Hazards of radiation _ GCSE Physics
Alpha and beta particles are charged, whereas gamma radiation is neutral. Remember that opposite charges attract, so if you were to fire all three particles through an electric or magnetic field the alpha particles would deflect towards...

Quantum Electrodynamics (QED)
In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's...
