Niels Bohr
Niels Bohr was a physicist born in Copenhagen, Denmark where he lived for most of his life. He won a Nobel Prize in physics in 1922 for his atomic structure and research on radiation emitted from atoms. He worked and researched all over the world, but eventually returned back to Copenhagen and finally passed away there. -
Atomic Model
Niels Bohr created an atomic model after observing the light emitted by heated hydrogen. He came up with the idea that electrons were orbiting the positively charged nucleus of atoms in specific layers or shells. This model was used until 1926 when Erwin Shrodinger discovered that electrons did not move in set paths like Bohr thought. Bohr's model won him the Nobel Prize in physics in 1922. -

Bohr VS Einstein
The great physicist Albert Einstein did not agree with Bohr's theories on quantum physics. Einstein did not agree with how uncertain Bohr's thoughts made the quantum world seem to be. Bohr believed that particles such as electrons had probabilities if not observed. However, Einstein believed that these particles have an independent reality regardless of observation. They argued and debated at a conference of physicists, and during this Einstein coined the saying "God does not play dice". -
Waves or Particles
Niels Bohr came up with a great philosophy in quantum physics. The idea he proposed was the complementarity principle. This principle states that objects have two properties that cannot be observed at the same time. A great example of this would be light, which acts like both a wave and particle but cannot be observed as both at the same time. Both of these behaviors exhibited by a quantum particle are mutually exclusive but complimentary of each other. -
Gone Nuclear
Niels Bohr came up with a theory that was a significant cause of the discovery of splitting an atom. He proposed that the nucleus of two atoms that have collided become indistinguishable from one another. He came up with this theory to explain nuclear reaction as a two-step process. The first was the development of the love-lived intermediate nucleus, and the second step was the decay of the nucleus. The first particle becomes a part of the particle that was hit, and then both disintergrate. -
