On May 16, 1960, American physicist Theodore Maiman presents the world's first operating laser at Hughes Research Laboratories, Malibu, California. Today, lasers are present everywhere, ranging from common consumer devices such as DVD players, laser printers, and barcode scanners to professional laser devices for surgery and various other skin treatments, or in industry for cutting and welding materials. Actually, it was Albert Einstein, who has laid the theoretical foundations for the laser in his 1917 paper Zur Quantentheorie der Strahlung (On the Quantum Theory of Radiation).
On August 8, 1902, English theoretical physicist Paul Adrien Maurice Dirac was born. Dirac is best known for his fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics.
On October 7, 1885, Danish physicist and Nobel Laureate Niels Bohr was born. Bohr made foundational contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922.
"We're going to shoot an ultraviolet laser into a (special type of) crystal, and out will come two. lower-energy photons that are entangled," Cramer said. For the first phase of the experiment, to be started early next year, they will look for evidence of
