Study Notes
Stephen Hawking: A Summary
- Stephen Hawking, a renowned theoretical physicist, used mathematics to explore black holes and the origins of the universe.
- He popularized complex scientific ideas to a broader audience, enabling millions to understand space-time, gravity, and humanity's place in the cosmos.
- Hawking was born in 1942 and died in 2018.
- He was diagnosed with ALS in 1963, which led to significant physical limitations, beginning in 1969.
- Hawking communicated using a speech synthesizer controlled by facial muscles.
Hawking's Contributions
- The term "black hole" emerged in 1967, although its concept originated earlier.
- Hawking was fascinated by black holes, especially how they might reveal the universe's origins, working to explore the possibility of the universe's processes reversing.
- He investigated, through his PhD thesis, the possibility of the universe's processes reversing, exploring the concept of "singularity," an infinitely dense and small point in space-time at the collapse of a star. His research further developed Einstein's general theory of relativity.
- His work on black holes was complemented by collaboration with Roger Penrose, a mathematician.
- Using quantum theory, Hawking predicted in 1974 that black holes emit heat and evaporate.
- His work contributed to understanding space-time, gravity, and humanity's place in the cosmos.
Milestones
- In 1966, Hawking's PhD thesis, exploring expanding universes, outlined the genesis of the universe from a singularity.
- He received the Lucasian Chair of Mathematics at Cambridge beginning in 1979.
- Hawking's renowned book, "A Brief History of Time," was published in 1988 and became a significant cultural phenomenon. It remained on the Sunday Times bestseller list for 237 weeks.
- Hawking was appointed Lucasian Professor of Mathematics at Cambridge University in 1979, a position he held until 2009.
- He undertook research on black holes and received other accolades for his work.
- He also wrote several popular science books, including A Brief History of Time.
- He traveled widely, giving public lectures to captivated audiences.
- He won the Breakthrough Prize in Fundamental Physics in 2018 (worth $3 million).
