The quantum world: A concise guide to the particles that make reality

Get to grips with the deepest layer of reality we know of with our inventory of the subatomic realm, from known particles like quarks and the Higgs boson to hypotheticals including the fifth force and strings in 11 dimensions

Caption Illustration of the double-slit experiment, showing a plane wave (top left) passing through a screen with two gaps. The gaps act as new wave sources and the wavefronts bend to create two sets of circular waves radiating outwards. These two new waves create an interference pattern as they interact. At the point where a wave peak from one hits a wave peak from another, or a trough hits a trough, they reinforce each other; their magnitudes are summed. This is known as constructive interference. Where a trough hits a peak, they cancel each other out. This is known as destructive interference.
