Levin explains black holes in easy-to-understand metaphors.... at least, as easy as black holes can be, because they are so complex and so far outside of everyday experience. She explains some really complicated theories of physics in relatively simple terms. The book is charming and engaging. ( ) Levin waxes rather lyrical about her favorite subject -- astronomical black holes -- in this whimsically illustrated minibook. Still, her fine presentation reaches to scientific concepts considerably more advanced than her visually dazzling _Nova_ episode did -- Hawking radiation, the information problem, the holographic principle, the firewall controversy, and the possible role of wormholes. Written somewhat tongue in cheek by an actual physicist and astronomer, this small book spends about 140 pages telling you all about black holes, how to approach them, and what (likely) happens if you fall inside before admitting that, in fact, there is no surviving a black hole. Good to know before I wasted a trip. I don't think I remember more than 5% of what I read right now, and that'll probably be gone in a few days, but still I very much enjoyed reading this book. Rather than feeling baffled and lost, as I have lately with science books, I swear I could feel my brain cells expanding as I read this even tho I wasn't grasping more than a fraction of it. That was a very agreeable experience. Also, I noticed that Levin has written a novel called "A Madman Dreams of Turing Machines", which I think I must read. Sense ressenyes | afegeix-hi una ressenya
"From the acclaimed author of Black Hole Blues and Other Songs from Outer Space--an authoritative, wholly accessible, fascinating guide to the most challenging phenomena of contemporary science, which is now the anchor of our understanding of the cosmos. Throughout her career, astrophysicist Janna Levin has focused, alongside her research, on making the science she studies not just accessible, but, perhaps more important, intriguing to the nonscientist. And that is what she has done again here, helping us to understand the black hole: perhaps the most opaque theoretical construct ever imagined by physicists. She explains how their existence came to be proven decades after they were first predicted in Einstein's 1915 general theory of relativity. And she explores the ways in which what we know about them has changed our most basic understanding of the galaxy, the universe, the whole expanse of reality that we inhabit. Lively, engaging and utterly unique, Black Hole Survival Guide is not just informative. It is as well, a wonderful read from first to last"-- No s'han trobat descripcions de biblioteca. |
