The way of chemistry

What is chemistry?

From thefreedictionary.com: “The science of the composition, structure, properties, and reactions of matter, especially of atomic and molecular systems.”

Around 1920-1930, it became clear that quantum mechanics (i.e. theoretical physics) essentially solves this problem.

Did Chemistry follow the way of Polaroid?

No.

They found the right way. And they are now flourishing!

How did they achieve this?
