Stephen Hawking, world renowned physicist passes away aged 76

Stephen Hawking was diagnosed with amyotrophic lateral sclerosis (ALS).

Due to the diagnosis with ALS, Stephen Hawking was unable to read and right. He used to communicate raising his eyebrow to choose letters on a spelling card, a form of augmentative communication. In 1986, web technology company WordPlus created the ‘Equalizer’ application wherein Stephen Hawking could press through a range of phrases.

The Black Hole Radiation was discovered by Stephen Hawking.

Before the Hawking Radiation , in 1970, Stephen Hawking and three scientists proved the existence of a ‘singularity in space time’, proving that space and time started due to the big bang and will end in black holes. Four years later, along with physicist Jacob Bekensetein, they proved that the black hole should thermally create and emit sub-atomic particles until they exhaust their energy.

Besides, Hawking was appointed the Lucasian Professor of Mathematics, a position once held by Sir Isaac Newton. Hawking held the position for 30 years till 2009 after which he was appointed the Dennis Stanton Avery and Sally Tsui Wong-Avery Director of Research in the department of applied mathematics at University of Cambridge.

He was a popular author and TV figure too.

Some of his famous authored books include ‘A Brief History of Time’, ‘Black Holes and Baby Universes and Other Essays’, ‘God Created the Integers: The Mathematical Breakthroughs That Changed History’ and his most recent book was ‘My Brief History’ in 2013.
