Scientists have long grappled with a fundamental question: what exactly is light? Is it a wave, flowing like ripples across water, or is it made up of tiny particles, like miniature paintballs zipping ...

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 ...

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 ...

Bohr’s atomic model was utterly revolutionary when it was presented in 1913 but, although it is still taught in schools, it became obsolete decades ago. However, its creator also developed a much ...

In two landmark experiments, scientists have overcome key barriers to building scalable quantum networks. Researchers at the Niels Bohr Institute created telecom-band quantum dots that emit coherent, ...
