Ever since Max Planck introduced the idea of the quantum to the world, physicists have argued about whether reality is more like sand or water. Planck’s famous 1900 discovery that energy is grainy — ...

The dual nature of light has long been a concern of scientists. It even led to the creation of the to the controversy between Albert Einstein and Niels Bohr on whether light can be observed ...

In a striking display of quantum physics, a team of researchers has recreated one of science’s most legendary experiments—with unprecedented precision. At MIT, scientists cooled thousands of atoms to ...

After escaping the Nazis by minutes and then getting smuggled through spy-infested Stockholm, the bomb bay of a British fighter jet might have been a relief to physicist Niels Bohr. His approach to ...

There is tremendous potential for new information technology based on light (photons). Quantum technology based on photons -- called quantum photonics, will be able to hold much more information than ...

Niels Bohr was born and educated in Copenhagen, Denmark. He lived, worked, and died there, too. But his mark on science and history was worldwide. His professional work and personal convictions were ...

The precise knowledge of one of two complementary experimental outcomes prevents us from obtaining complete information about the other one. This formulation of Niels Bohr's principle of ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly ...
