Who was Stephen Hawking?
On 08 January 1942, Stephen William Hawking was born in Oxford, England. His interest towards functioning of universe from young age earned him the nickname 'Einstein'.
However, at a young age of 21, he was diagnosed with a neurodegenerative disease. "The music of composer Richard Wagner and the loving support of his future wife Jane Wilde motivated Hawking to dedicate himself to physics, math, and cosmology," reads the official blog by Google.
Later, he went to defend his doctoral thesis “Properties of Expanding Universes” at the University of Cambridge. His thesis presented the key characteristic of black holes, arguing that space and time originated from a singularity, a point both infinitely small and dense.
Moreover, in 1974, he went on to discover that particles could escape black holes, which is widely considered his most important contribution to physics.
Cambridge University, in 1979, appointed Hawking as the Lucasian Professor of Mathematics, a position held by Isaac Newton in 1669. They also released his doctoral thesis to public on its website in the year 2017.
