Philip Ball looks at how a little-known paper by Niels Bohr demonstrates the turmoil in physics on the brink of quantum ...

For example, according to classical physics, the electrons orbiting the nucleus should lose energy until they spiral down into the center, collapsing the atom. Bohr proposed adding to the model ...

His luck, or fate, was to come of age in the Germany of the late 1920s, just as Heisenberg, Niels Bohr and others were fleshing out the bones of quantum mechanics. This was revolutionary physics ...

In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't quite right. By all rules of classical physics, it should be very unstable. For one thing, the orbiting electrons should ...

This lecture marks a key moment in Bohr’s scientific journey, coming shortly after he had developed his model of the atom, which had revolutionized the field of atomic physics. Here’s a ...

Bohr was unperturbed by the implications, trusting in the equations. But Einstein would not accept a style of physics that, as he saw it, abandoned its duty to describe the real world. Nor ...

As profound as was the work of Albert Einstein and Niels Bohr in physics, their thoughts and practice in education were of the same nature. In 1952 Einstein wrote an article titled, “Education f ...

There is an anecdote about the Danish Nobel Prize-winning physicist Niels Bohr. He had invited several scientists to his ski cottage. One of them noticed a horseshoe nailed above the door and ...

What is quantum physics? Put simply ... which was first developed in the 1920s by Niels Bohr, Werner Heisenberg, Erwin Schrödinger and others. It characterises simple things such as how the ...
