Collaboration between Stephen Hawking and Sir Roger Penrose (born 8 August 1931) has transformed modern understanding of the universe, especially of black holes.

Multiplicity of dimensions may baffle imaginations: Stephen Hawking easily conceives of 11 dimensions.

Black holes have beguiled such astrophysical geniuses as Albert Einstein and Stephen W. Hawking.

Comments
Thank you, Hollie, for stopping by and visiting Dr. Stephen Hawking's legacy via this wizzley.
Me too, I find string theory a bit frustrating even as Dr. Hawking furnishes us fruitful ways to fight that personal and professional fulfillment not formed -- like him! -- by fluent astrophysics.
Isn't it impressive that Dr. Hawking is able to imagine at least 11 dimensions?
I love Stephen Hawking! I have often grappled with String Theory and been unable to quite get my head around it but Dr Hawking had a really easy writing style and was also excellent at interpreting complex scientific theory for the masses.
This book review is, since Wednesday, March 14, 2018, dedicated to the memory of Dr. Stephen Hawking (Jan. 8, 1942-Mar 14, 2018), with thanks for all the astrophysical truths that he manifested as simple truths for household-word-recognition understanding.
CruiseReady, All of Stephen Hawking's books are worth having on the shelves. He knows how to write for all levels of familiarity and non-familiarity. They generally average 150+ pages of comprehensible examples and understandable explanations by the world's most eminent astrophysicist on black holes, neutron stars, and quasars.
Hmmm ,,, Now, I am thinking that this book needs to be added to my library. Or more accurately, that my library needs to have this book added to it!
MBC, The book is definitely worth reading. Stephen Hawking's amiable personality comes through via his engaging style.
I saw the movie the Theory of Everything - it was fantastic! I'm sure the book is worth reading.
Mira, It's admirable that Stephen Hawking is willing to revise in favor of clarity and to correct errors in theory. I have read so many of his writings, and all of them are enlightening. I recommend this book!
I may read this book, too, even though apparently after writing this book he changed his views . . . again! :) Still, it would be interesting even as an exercise. It's amazing how we live on a tiny planet in this whole (mostly) unknown and poorly understood universe.
