Stephen Hawking (1942–2018): Toward a complete understanding of the universe by James Hartle, 2018.

2 works by Hawking stand out:

  • Beginning of the universe ;

Quantum cosmology

The beginning of universe: from 4 space dimension → (decouple) 3 space dimension + 1 time dimension.

  • The end of black holes ;

Black holes are not black hole when take quantum mechanics into account, black holes will have temperature and radiation, “white hot” named by Hawking.

Hawking’s ability outstanding:

  1. Focus on the essentials of problems ;
  2. Give up some “right” ideas ;
