Dalton, Thomson, Rutherford and Bohr. Dalton, Thomson, Rutherford and Bohr. Schrödinger and Heisenberg, and many, Schrödinger and Heisenberg, and many, many more. Used their brains to venture many more. Used their brains to venture in the realm of inner space and found the in the realm of inner space and found the world of the atom was a weird and world of the atom was a weird and wondrous place.wondrous place.

Dalton did experiments and said, “I think Dalton did experiments and said, “I think it’s clear, atoms are tiny indestructible it’s clear, atoms are tiny indestructible spheres.”spheres.”

Thomson worked with cathode rays and Thomson worked with cathode rays and said, “I disagree. A plum-pudding model said, “I disagree. A plum-pudding model makes much more sense to me.”makes much more sense to me.”

Heisenberg said, “Forget it, there’s no Heisenberg said, “Forget it, there’s no way to know the orbit or a path, where way to know the orbit or a path, where the electron’s gonna go.”the electron’s gonna go.”

Schrödinger used lots and lots of fancy Schrödinger used lots and lots of fancy mathematics, and made a model of the mathematics, and made a model of the atom based on quantum mechanics. It atom based on quantum mechanics. It has orbitals and those are based on has orbitals and those are based on probability. The atom is a fuzzy blob of probability. The atom is a fuzzy blob of pure uncertainty.pure uncertainty.
