The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

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 ...

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 ...

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 ...

Niels Bohr's Nobel Lecture on December 11, 1922, titled The Structure of the Atom, is one of the most significant contributions to our understanding of atomic structure and quantum mechanics. This ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American One of the standout anecdotes in Carl ...

Seeing the world through a quantum lens brought us some of the most transformative technological innovations of the 20 th century: nuclear energy (and bombs), transistors and semiconductors, lasers ...

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 ...

One way to obliterate an atom is to shoot it with the planet's most powerful X-ray gun. Linda Young tried that experiment in October 2009, when she was testing the newly opened X-ray free-electron ...
