Heard of Stephen Hawking, you must've right? He died recently and he lived for over 60 years, which is much more than most with his condition.
I have heard of him, he was a genius!
He really was! He was a physicist, cosmologist, and an author!
I didn't realize he did all that! But, I'm not surprised, and he sure was a role model for many!
I know, he was even a Director of Research at the Centre for Theoretical Cosmology in the University of Cambridge.
