Light travels more slowly in materials, such as water, than it does in a vacuum. No particle can travel faster than the speed of light in a vacuum. Particles that travel faster than the speed of light in a given material emit a cone of light, in the same way that objects exceeding the speed of sound emit a sonic boom. Detectors that use this light to detect subatomic particles are known as Cherenkov detectors.

العملية التي يتحول النيوترونات في نواة بروتون بانبعاث إلكترون ونيوترينو المضادة يعرف اضمحلال بيتا. عندما اثنين من النيوترونات الخضوع لهذا التحول في وقت واحد، تسمى العملية تحلل بيتا المزدوج. أهمية خاصة هو عملية افتراضية لتحلل بيتا المزدوج نيوترينولس، فيها تحويل النيوترونات بانبعاث الإلكترونات اثنين، لكن لا النيوترونات المضادة.

A unit of energy equal to the amount kinetic energy an electron gains after being accelerated through an electric potential of 1 Volt. It can also be used as a unit of mass by applying Einstein's relation E=mc<sup>2</sup>.

At very small distances, the principles of quantum mechanics are necessary to accurately describe physical phenomena. Developing a theory that incorporates both the principles of quantum mechanics and gravity, a theory of "quantum gravity", has proven to be extremely difficult. String theory is the first real hope of providing such a theory.
Industry:Physics
In microscopic systems, particles such as electrons and protons behave like waves. Quantum mechanics replaces the more familiar Newtonian mechanics to describe such phenomena.
