Notes:
If any one person can be said to be the most important figure in the development of quantum mechanics, it must be Niels Bohr. It was Bohr’s intellectual insight into the interpretation of experiments and the meaning of particle and wave concepts that led most directly to our modern understanding of how physics works on the microscopic level.
