Laser is an acronym for light amplification by stimulated emission of radiation. It is a device that controls the way energized atoms release photons. The principles that govern lasers are rooted in quantum mechanics.
Paul Adrien Maurice Dirac(British, 1902-1984)
was a theoretical physicist and founder of the field of quantum physics. He is also known for the Dirac Delta Function.
The Dirac Equation is a relativistic quantum mechanical wave equation:
where m is the rest mass of the electron, c is the speed of light, p is the momentum operator, is the reduced Planck’s constant, x and t are the space and time coordinates respectively, and is a four-component wavefunction.
Max Karl Ernst Ludwig Planck (German, 1858-1947)
is considered to be the founder of quantum theory, and is regarded as one of the most important physicists of the twentieth century.
Amalie Emmy Nöther
established Nöther’s theorem, a central result in theoretical physics that expresses the one-to-one correspondence between symmetries and conservation laws. It is deeply tied to quantum mechanics.
