Stephen Hawking was a renowned British theoretical physicist, cosmologist and author. He was born in 1942 in Oxford, England and went on to study at both the University of Oxford and University of Cambridge. Hawking made groundbreaking contributions to the fields of cosmology and quantum gravity. He authored several popular science books explaining his work, with one titled "A Brief History of Time" spending over 250 weeks on bestseller lists. Hawking overcame amyotrophic lateral sclerosis and was almost entirely paralyzed but continued his scientific work using a speech generating device. He died in 2018 at his home in Cambridge at the age of 76.

2. Hawking was a British theoretical
physicist, cosmologist, author and
Research Director at the University
of Cambridge.

3.  Hawking was born on 8 January
1942 in Oxford by Frank and Isobel
Eileen Hawking. Hawking had two
younger sisters, Philippa and Mary,
and an adopted brother, Edward
Frank David.

5.  He began his schooling at the Byron
House School in Highgate, London. At
first Hawking was not successful
academically. With time, he began to
show significant natural ability for
scientific subjects and decided to study
mathematics at university.

7.  Hawking started his university
education at University College,
Oxford, in October 1959 at the age of 17.
For the first 18 months, he was bored and
lonely – he found the academic work
"ridiculously easy".

9.  Hacking's first year as a doctoral student
was difficult. When Hawking began his
graduate studies, there was much debate
in the physics community about the
theories of the creation of the universe.
Inspired by Roger Penrose's theorem of
a spacetime singularity in the centre of
black holes, he applied the same thinking
to the entire universe.

11.  After being diagnosed with motor
neurone disease, Hawking fell into a
depression. His disease progressed more
slowly than doctors had predicted.
Although Hawking had difficulty
walking unsupported, and his speech
was almost unintelligible, the initial
diagnosis that he had only two years to
live, proved wrong.

13.  Hawking achieved commercial success with
several works of popular science in which he
discusses his own theories and cosmology in
general. His book A Brief History of
Time appeared on the British Sunday Times best-
seller list for a record-breaking 237 weeks.
 A Brief History of Time (1988)
 The Universe in a Nutshell (2001)
 On the Shoulders of Giants (2002)
 My Brief History (2013)
 Brief Answers to the Big Questions(2018)

15.  His career was so significant that he won a
huge number of awards and honors during
his life time.

Adams Prize (1966)

Eddington Medal (1975)

Maxwell Medal and Prize (1976)

Heineman Prize (1976)

Hughes Medal (1976)

Albert Einstein Award (1978)

17.  His special way of living and his various
achievements intrigue the interest in
Hollywood. As a result, a movie about
Hawking's life called “The theory of
everything” came out in 2014. Nevertheless,
there were some previous films such as
“Hawking” and “Beyond the Horizon” which
didn't succeed in presenting his life in detail.

19.  Hawking expressed concern that life on
Earth is at risk from a sudden nuclear
war, a genetically
engineered virus, global warming, or
other dangers humans have not yet
thought of.
 Hawking stated that, because of the
hugeness of the universe, aliens may
exist, but that contact with them should
be avoided

21.  Hawking was an atheist and believed
that "the universe is governed by the
laws of science". He stated: "There is a
significant difference between religion,
which is based on authority, and science,
which is based on observation and logic.
Science will win because it works."

23.  Even after the loss of his speech, he was
still able to communicate through
a speech-generating device, initially
through use of a hand-held switch, and
eventually by using a single cheek
muscle. Hawking died peacefully at his
home in Cambridge, England, on 14
March 2018, at the age of 76 after being
paralyzed for decades.
