Among his other (more significant) actions, his book A Brief History of Time was the successor to Carl Sagan’s Cosmos. Science for the masses. He died yesterday (3/14/2018), sad, but he received his ALS diagnosis in his twenties (received a grim “a handful of years to live” talk, but lived 50 years beyond that).
I liked the math in his famous book (that math that I could follow); this was a complaint of many readers of the book (“too much math!”).
With his compromised (physical) condition, he still figgered out so much about the cosmos – specifically, the nature of black holes.
Einstein vs. Newton vs. Hawking??
No good answer, but that they are all put together…..says something.
