The experiments, which spanned more than a decade, suggest that the electron differs from being round by less than 0.000000000000000000000000001 cm. Just so you can get an estimate, if the electron were as big as the solar system, it would still be spherical to within the width of a human hair.

a team from the Imperial College London concluded that the electron is actually incredibly round, thus making the most accurate estimate of its shape.

At a quantum scale, the motion of electrons and protons is completely and genuinely random, since it doesn’t follow a clear path of cause and effect. You basically have no idea what’s going to happen. If you can measure this somehow, than you’ve got yourself an absolutely random value.

The researchers used pulses of laser light, which only last a trillionth of a second, that were directed through a diamond. The light comes and goes through the diamond, however when it exists it’s changed, since it has to pass through quantum vacuum fluctuations, the microscopic flickering of the amount of energy in a point in space. Scientists can measure these pulses of light that emerge from the experimental set-up, measurements which are the truly random.
