Study Notes
Stephen Hawking
- Renowned theoretical physicist
- Used mathematics to understand "black holes" and the universe's origins
- Popularized science, enabling millions to comprehend space-time, gravity, and humanity's cosmic place
Hawking's Life
- Born in St. Albans, UK, in 1942
- Diagnosed with ALS in 1963 (motor neurone disease)
- Confined to a wheelchair from 1969
- Communicated via a computer-linked speech synthesizer, controlling it with facial muscles after losing vocal ability in 1985
Black Holes
- "Black hole" term coined in 1967
- German physicist Karl Schwarzschild hypothesized their existence earlier (1910s)
- Matter drawn into black holes creates X-rays
- 1964: Astronomers detected "X-ray binaries" near star-forming regions, suggesting the existence of possible black holes
- Hawking's fascination with black holes stemming from potential insights into the universe's origin
- Penrose's work (p.300) proved that a dying star's collapse can create a singularity (infinitely small and dense point in spacetime)
Hawking's Work and Recognition
- PhD thesis: Proposed that the universe's creation process could reverse
- 1974: Predicted that black holes emit heat (applying quantum theory)
- 1979: Became the Lucasian Professor of Mathematics at Cambridge University (a position previously held by Isaac Newton)
- 1988: Published A Brief History of Time which became a critical and commercial success, making his work more accessible
