(PhysOrg.com) -- In 1974, Stephen Hawking predicted that black holes emit thermal radiation due to quantum effects, which causes the black holes to lose mass and perhaps ultimately vanish. But despite numerous attempts to ...
(PhysOrg.com) -- At very cold temperatures, in the absence of light, a photomultiplier will spontaneously emit single electrons. The phenomenon, which is called "cryogenic electron emission," was first observed nearly 50 ...
Nuclear physics, which studies the huge variety of nuclei in all the matter that surrounds us, not only provides answers about the evolution of our universe, it also provides the underpinning knowledge needed to exploit nuclear ...
