Niels Bohr's model of the hydrogen atom—first published 100 years ago and commemorated in a special issue of Nature—is simple, elegant, revolutionary, and wrong. Well, "wrong" isn't exactly ...

A nearly 400 year-old formula for pi has been spotted in a quantum-mechanics formula for the energy states of the hydrogen atom, according to researchers in the US. Derived by English mathematician ...

Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, physicists have created giant, millimeter-sized atoms that resemble it more closely than any ...

One hundred years ago, Niels Bohr developed the Bohr model of the atom, where electrons go around a nucleus at the centre like planets in the Solar System. The model and its implications brought a lot ...

Picture an atom, and you may imagine spherical electrons orbiting a nucleus packed with particles like neutrons. Only certain orbits - quantum levels - are possible. It's a simplistic model, yet ...

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 ...

Quantum studies took a massive leap in the middle of the 20th century, with a host of European scientists successfully attempting to unlock the mysteries of the atom. In these endeavours, Danish ...

HOUSTON -- June 30, 2008 -- Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, ...
