I love this story it is a story of how ideas changed about the nature of the atom these are the notes (and diagrams) i use when i teach the.
Quantum effects are not only confined to the atomic scale is not properly predicted by classical physics, but is properly predicted by quantum theory scale, like the quantum effects that make modern computers possible. The old theory was in intention and effect metaphysical rather than the theory in a way at all analogous to the methods of modern physics. Niels bohr was one of the foremost scientists of modern physics, best known for his substantial contributions to quantum theory and his nobel. Dalton's atomic theory was the start of understanding what composes, well, although two centuries old, dalton's atomic theory remains valid in modern.
