Overview
Physicist (物理学者, butsurigakusha) is a natural scientist who primarily explores physics.
Einstein is one of the most famous physicists in the world.
He was too smart to think about anything too advanced, and many of them became eccentric.
And after all of his research, he came up with the outlandish theory of relativity, which is not an outlandish theory, and the atomic bomb, a weapon of mass destruction.
