That's a better way of looking at it. It's not magic, but it's the principle with which to look at subatomic particles.
There's more nuance that the mathematics shows, of course, but you got the whole gist of it.
Edit: On top of this, the reason why this works, is because of wave-particle...
That's not the right way of looking at it. The fundamental problem most people have is that they want to be able to look at the world and see it for what it is. But there's a fundamental principle in quantum physics that says what you observe an electron doing is not how the electron actually is...
Not necessarily the same thing. You're thinking of the Heisenberg Uncertainty Principle. Superposition is a bit different.
And regarding it being a tool rather than an objective law. It's both.
I'm a student of physics, so I feel I can help you and others to get a practical, if simplistic, understanding of quantum mechanics.
First off, everyone misinterprets the superposition principle.
All it states is that since matter is quantized, separate possible quantum states can exist at the...
