My most admired scientist is Alber Einstein for developing the theory of relativity, which is now one of the two pillars of modern physics.
He wrote many books which includes
The World as I See It (1934)
Ideas and Opinions (1954)
Relativity: The Special and the General Theory
Out of My Later Years
Autobiographical notes
These books sometimes makes you understand some aspects of life.

Favorite quotes from Albert Einstein:

1. Insanity: doing the same thing over and over again and expecting different results.

2. Imagination is more important than knowledge.

3. The important thing is not to stop questioning. Curiosity has its own reason for existing.
