... What has to be left out in order to fit the story into an A-level option? This is a real problem. Looking back on past events and ideas, it’s easy to see, or to think we see, which of them led nowhere or were of secondary importance, and to leave them out. But at the time they may have been consider ...

Standard Model
... The photon is a quantum of light and all other forms of EM radiation, and the force carrier for the EM force. The photon is currently understood to be strictly massless, but if the photon is not a massless particle, it would not move at the exact speed of light in vacuum, c. Its speed would be lowe ...

... This one is harder. The edge effects should only affect the small fraction of particles that pass close enough to the edge to hit it. The bulk of the particles should just pass through, with a wider slit, giving rise to a wider pattern. 13) When we narrow the slit, we have a better idea of where the ...
