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 ...

Bohr began to work on the problem of the ... His model was a huge leap forward in making theory fit the experimental evidence that other physicists had found over the years. A few inaccuracies ...

Further, Bohr’s theory was also unable to explain the splitting of spectral lines in the presence of magnetic field (Zeeman effect) or an electric field (Stark effect). It could not explain the ...

In 1927, Werner Heisenberg was in Denmark working at Niels Bohr's research institute in Copenhagen. The two scientists worked closely on theoretical investigations into quantum theory and the ...

SCIENCE is steadily becoming severely specialised. The proportion of amateurs (in the restricted sense of the word) among original workers of all ranks decreases slowly but surely. The average ...

Acceptance of this model grew after it was modified with quantum theory by Niels Bohr. For his work with radiation and the atomic nucleus, Rutherford received the 1908 Nobel Prize in chemistry.

The most prominent answer in the 1930s came from the Copenhagen interpretation, developed in the Danish city by luminaries of quantum theory, Niels Bohr and Werner Heisenberg. This says that there ...

Bohr's 'solar system' model of the atom is the ... Chadwick used a version of Rutherford's experiment, using a sheet of beryllium and a paraffin block instead of gold foil. He was able to prove ...
