Stephen Hawking was an English theoretical physicist, cosmologist, and author.

He was director of research at the Centre for Theoretical Cosmology at the University of Cambridge at the time of his death.

Stephen 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.

Stephen Hawking was born on 8 January 1942 in Oxford, England.

Stephen Hawking worked on the basic laws which govern the universe.

With Roger Penrose, he showed that Einstein’s General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes.

In 2006, Hawking posed an open question on the Internet:

“In a world that is in chaos politically, socially and environmentally, how can the human race sustain another 100 years?”, later clarifying: “I don’t know the answer. That is why I asked the question, to get people to think about it, and to be aware of the dangers we now face.”

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.

Professor Stephen Hawking received twelve honorary degrees, was awarded the CBE in 1982 and was made a Companion of Honour in 1989.

He was the recipient of many awards, medals, and prizes and is a Fellow of The Royal Society and a Member of the US National Academy of Sciences.

Stephen Hawking Quotes:

1. “One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don’t throw it away.”

2. “My expectations were reduced to zero when I was 21. Everything since then has been a bonus.”

3. “It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. It’s a crazy world out there. Be curious.”

4. “My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.”

5. “One of the basic rules of the universe is that nothing is perfect. Perfection simply doesn’t exist…..Without imperfection, neither you nor I would exist”

6. “One is always a long way from solving a problem until one actually has the answer.”

7. “We each exist for but a short time, and in that time explore but a small part of the whole universe”

8. “What did God do before he created the universe?”

9. “The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired.”

10. “It is said that there’s no such thing as a free lunch. But the universe is the ultimate free lunch.”

11. “The computer in your cell phone today is a million times cheaper and a thousand times more powerful and about a hundred thousand time smaller than the one computer at MIT in 1965.”

12. “I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.”

13. “We create history by our observation, rather than history creating us.”

14. “There could be whole antiworlds and antipeople made out of antiparticles. However, if you meet your antiself, don’t shake hands!”

15. “Today, we commit to this next great leap into the cosmos because we’re human, and our nature is to fly.”
