Even when he finally did, he uttered his words twice. When he started school, he still had speech difficulty until the age of nine.

Born in a German city called Ulm, his mother believed Einstein was a freak because his head seemed to be too big for his body.

Her worry had some basis because Einstein actually suffered from a medical condition called “Benign Macrocephaly”, a disorder that could lead to mental retardation.

One of the most recognized and well-known scientists of the century, he was awarded a Nobel Prize in Physics for his work on photoelectric effect titled: “On a Heuristic Viewpoint Concerning the Production and Transformation of Light”.

Upon his death, his brain was preserved and studied.

A 1999 study done by Mcmaster University found that his brain did not have it’s parietal operculum region, a part of the brain needed for speech, reading or writing.

To compensate for that, his brain adapted by enlarging his parietal lobe by 15% wider. This part of the brain is responsible in giving him superior mathematical thought, visuospatial cognition, and imagery of movement.

The study also found that Einstein’s brain had 73% more glial cells ( special cells that provide support and nutrition to the brain) than normal brains.
