Study Notes
Stephen Hawking
- Renowned theoretical physicist, explored "black holes" and the universe's origins
- Popularized science, making complex concepts accessible to millions
- Born in London, 1942, died 2018
- Developed a speech synthesizer to communicate after losing voice due to ALS (amyotrophic lateral sclerosis)
Hawking's Life and Work
- Studied at Cambridge, earned PhD in cosmology
- Diagnosed with ALS in 1963, confined to wheelchair from 1969
- Contributed significantly to understanding of black holes and the universe's beginning
- Collaborated with Roger Penrose to prove that gravitational singularities exist
Black Holes
- Term "black hole" coined in 1967
- Karl Schwarzschild hypothesized existence earlier
- Astronomers observed X-ray binaries, evidence of black holes
- Hawking researched black holes in his doctoral thesis
- Black holes could yield insights into the universe's creation
- Studied work of Penrose, suggesting that a large star's demise leads to a point of infinite density, singularity in space-time
Major Accomplishments
- Wrote his PhD thesis on expanding universes
- Proved existence of gravitational singularities
- Discovered that black holes emit heat and evaporate (quantum theory, 1974)
- Became Cambridge's Lucasian Professor of Mathematics
