Study Notes
Stephen Hawking's Life and Work
- Stephen Hawking was a renowned theoretical physicist and science popularizer
- He was born in Oxford, England, in 1942
- At age of 1963, while studying for a doctorate degree, Hawking was diagnosed with ALS, which led to a communication challenge
- He communicated using speech synthesizer
- He used a computer linked to a speech synthesizer
- His work dealt with, black holes, singularities, and the universe's origin.
Hawking's Scientific Contributions
- Hawking's PhD thesis explored the properties of expanding universes. His findings stated the universes started from an initial singularity
- Proved the existence of gravitational singularities
- In 1974, he used quantum mechanics, to predict that black holes release heat radiation (Hawking radiation)
- This work theorized black holes will eventually evaporate through the release of energy
- His research investigated the possibility of black holes absorbing matter, and converting it into radiation
- Studied general relativity and its implications
- Explored the relationship between general relativity and quantum mechanics
