Einstein was a bit of a weirdo.

Words cam with difficulty to him, but images came easier.

He wasn’t mathematically brilliant, but could pull his weight.

He was different. He had a clear way of thinking that wouldn’t register on an intelligence test.

His first paper on special theory of relativity  can be understood by ordinary mortals: no jargon, just simple ideas, inescapable logic. Just brilliant in its simplicity.
