The Universe in a Nutshell (عالم المعرفة #291)
Now, in a major publishing event, Hawking returns with a lavishly illustrated sequel that unravels the mysteries of the major breakthroughs that have occurred in the years since the release of his a...more
Decir que Stephen Hawking es uno de los mejores físicos del siglo XX no es dar una gran noticia. Su gran capacidad, unida a la enfermedad que le ató a una silla cuando aún era joven (Esclerosis lateral amiotrófica, o la enfermedad de Lou Gehrig, llamada así por un jugador de béisbol), le han convertido en un icono.
Hawking se ha dedicado a intentar unir la Relatividad y la Mecánica cuántica. Ha publicado muchísimo y suyo es el mérito de la formulación del primer efecto medible (aunque aún no haya...more
Бог е мъртъв, каза Ницше. Ницше е мъртъв, контрира Бог. Бог никога не е съществувал, затапи и двамата Хокинг. И биде светлина.
„Вселената в орехова черупка” е продължение на „Кратка история на времето”, но е далеч по-шарена и смилаема. След като описва основата на физиката във „Върху раменете на гиганти”, Хокинг ни довежда до последните й достижения (изключвам откритията на женевския колайдер, чието включв...more
There are a few observations in this book that stood out as ways of conveying difficult concepts. Spacetime is best viewed not as passive background, for example, but as an active participant "in the dynamics of the unive...more

While I'm sure the content is dumbed down from Stephen Hawking's level, most of it is covered at a level and speed that kept it out of my comprehension. To be honest I find a lot of modern theories and ideas very skept...more
Indrukwekkend hoe de intelligentste man van deze tijd zo'n toegankelijk boek kan schrijven over een aantal anders moeilijk te begrijpen concepten uit de wetenschap.
Hawking wijdt uit over zwarte gaten, tijds dilatatie en waarom het heelal waarschijnlijk geen begin en einde heeft (in tijd en ruimte) maar toch niet oneindig is (noch in ruimte, noch in tijd).
Hij legt op een heel bevattelijke manier de thermodynamische wet van de entropie ui...more
This was no exception, as Hawking cover some of the most all encompassing ideas in physics and philosophy and sums it up in a very short amount of time. He does it with his own personal brand of humor and modesty.
If I have any complaints at all - it is in the area of the habit he has of taking theory and presenting it as fact. Some of the th...more
в даному витворі більше уваги приділено квантовій механіці: невизначеність Гейзенберга і кіт Шрьодінгера :)
але написано це так просто і чітко, що просто дивуєшся.
знайшов два дуже влучні відгуки:
"Эта книга обручает детские чудеса с гениальным интеллектом. Мы путешествуем по вселенной Хокинга, перенесение туда силой его разума"
і від New York Times:
"Живо и интригующе. Хокинг от природы наделен даром учить и р...more
I presume my feeling of this book would be vastly different if I had attempted to make sense of the complex maze that it would have been to read this from cover to cover. By listening to it there is opportunity to get lost in amazement of what you do not understand instead of being overwhelmed and frustrated by it. It was for me, unusually philosophically satisfying. Now this could be a co...more
Of the three Hawking books I have read (A Brief History of Time, The Universe in a Nutshell, A Briefer History of Time) I think this ranks #2. It is informative and understandable, but Briefer History is more accessible and more up-to-date.
If you want a book that deals more with the mathematics of physics (without presenting any actual formulas or equations) N...more
Dislikes: It's a little difficult to separate what is meant as metaphor and what is established scientific fact. Hawking often breezes over the reasons for making the main assumptions crucial to m...more
I'll admit it; my brain is nutshell-like, and therefore, Hawking's rate of explanation required me to review some concepts several times.
But just because you got a bachelor of arts to avoid that math requirement like I did, don't let that stop you from trying to grasp at least 50% of what Hawking is saying here. Absorbing a fraction of genius is better than absorbing none at all all.
In fact, I'd wag...more
So all in all this is a...more
The author's contention that a black hole is not totally black is somewhat difficult to accept even for a layman. Then what scientific commotions this...more
• Quantum mechanics
• General relativity
• 11-dimensional supergravity
• 10-dimensional membranes
• Black holes
Branes were the most confusing for me, but I think I got the gist of them by the end of the book. I recommend this book to anyone interested, it is well written and mostly understandable for th...more
Don't get me wrong, it's a really excellent book for science geeks, minor or major. It even won a science book award in 2002. And Hawking does dumb stuff down the best that he can. The entire book didn't flummox me, just most of it.
Before she got to my bedside, I managed to turn the page by myself. We both were amazed and happy! This was a big milestone in my recovery, and I will never forget it. I...more
This is an excellent book for those interested in science. But remember, science did not create the universe, it only describes it.
