A Brief History of Time by Stephen Hawking
My rating: 5 of 5 stars
I reread “A Brief History of Time” every few years thinking that, if I read it enough, I’ll understand it. Originally published in 1988, this 2017 edition is wonderfully updated by Stephen Hawking himself, who is the longest surviving victim of Lou Gehrig’s disease. Since the original publication, Hawking and others have determined that the prospect of a big crunch at the end of the universe is highly unlikely. That revelation, and others, makes it fascinating to explore the progress that has been made in cosmology and quantum physics in twenty years. Evaporating black holes, gravity waves, the multiverse, and the uncertainty principle; these mind-bending concepts, and many more, are laid bare by Hawking’s straightforward explanations. Straightforward? Well, all things are relative, including time and gravity. Hawking does speak plainly and with humor, but my eyes glaze and my brain hurts every time he says “…the sum over all possible histories.” Nevertheless, this is a book to read and reread by all thinking persons.
