The start
Niels Henrik David Bohr was born in Copenhagen, Denmark on October 7, 1895. The future Danish physicist would grow up to be one of the most important figures in theoretical physics as his work changed the way scientist examined the world. Source: britannica.com/biography/Niels-Bohr -
Rethinking the atom
In 1913, Bohr proposed his new model of the atom. In his model energy is transferred through levels of orbit. Compared to the old model, also called the Rutherford model, the newer theory showed electrons in a systematic order rather haphazardly surrounding the atom’s center.

Bohr vs. Einstein
During the Solvay Conference in Brussels Bohr suggested that atoms have an infinite number of possibles only when not being observed. Einstein disagreed saying his famous quote, “God does not play dice.” https://youtu.be/SBgC0PyIomU Source: nature.com/articles/d41586-018-03793-2 -
Complementary principle
One of Bohr’s most controversial idea was that of complementary. This idea challenged what the philosophy of science stated at this point as he said that scientist shouldn’t focus of what was being studied but rather the results and the experiment itself. Up until this point it was a widely accepted idea that everything in the universe could be defined by properties.

Period: to
Quantum mechanics
Bohr dedicated the last portion of his life to writing about quantum theory. Bohr mainly focused on his theory that an electron could be measured as a wave or a particle but not both. It was also during this time that he stressed the idea that an experiment results were only as good as the tools used to measure the data. Source: livescience.com/32016-niels-bohr-atomic-theory.html
