Chemistry, until my childhood, not that long ago, was regarded as a calculating device. Because you couldn't reduce to physics. So it's just some way of calculating the result of experiments. The Bohr atom was treated that way.
[About the great synthesis of atomic physics in the 1920s:] It was a heroic time. It was not the doing of any one man; it involved the collaboration of scores of scientists from many different lands. But from the first to last the deeply creative, subtle and critical spirit of Niels Bohr guided, restrained, deepened and finally transmuted the enterprise.
This is the most important joke I've ever heard. Niels Bohr, the founder of Quantum Physics, had a friend to dinner. As the friend left, he noticed a horseshoe nailed above Bohr's front door. He said to Bohr, accusingly, "Niels, you're a great scientist. You can't believe in superstitions. " Bohr answered, "I don't, but apparently it works anyway. "As with confirmation bias, we tend to lean toward superstitions that benefit us.
Since Einstein developed his theory of relativity, and Rutherford and Bohr revolutionised physics, our picture of the world has radically changed.
