Through Heisenberg's Uncertainty Principle, it's proven that you can't pin down where an electron is and how fast it's moving at the same time. The Bohr model did not look into this. The main reason for that thought was that it pictured electrons like little planets that would move in a loop around
De Broglie had the idea that everything that moves has a bit of wave behaviour. Technically, that includes any person, a football, and even a bus. The catch is that for big things, the mass is so large that their wavelength is insanely tiny. It's so tiny it's impossible to notice. That's
