Black Holes: The Key to Understanding the Universe

Product Information

All of this disregards entirely that I am already sort of tied up with a pseudo-career in a different scientific discipline and do not relish the thought of attending university again. Nor am I particularly skilled at focussing on multiple things, fond of starting over, or withholding anything of value from the theoretical physicists that they haven't already got covered.

There’s an old saying I think by Stephen Hawking that every equation you include in a popular level science book will half the effective book sales. Well, Cox and Forshaw deserve credit for taking a brave plunge (and by my estimate forgoing 99.999999% of their book sales based on Hawking’s formula) because one of the highlights of this book is the scattering of equations that are accompanied by careful explanation and insight. It’s always tempting to bask in the self-congratulatory delusion that if I just really concentrate on something hard enough I’d be able to understand it. But this book proved me wrong from the very first spacetime Penrose diagram that slowly sent my protesting brain over the event horizon and to the singularity while being simultaneously vaporized and spaghettified.

Despite the book’s brevity, Rovelli doesn’t flinch from discussing the tougher concepts. He warns you that you might find some of them a little confusing. I must confess that I’m still a little hazy on whether or not my inability to remember the future is just a perceptual illusion, or if it’s a fundamental consequence of the underlying physics. But Rovelli reassures you that none of that really matters and that what’s important here is the experience of being transported. If that’s true then the book more than does its job. Neil Tyson is one of the greatest scientific educators we have ever had. He is probably unmatched when writing popular science books, where he covers topics that can be very counterintuitive. But he explains astrophysics very smoothly that anybody can understand without scientific knowledge.

At the same time, it takes several days to get enough data to get a clear picture over a long period. So it’s an enormous task that takes place over years and years.

All these questions are exciting, and we all want to know their answers. But the point is, are these questions answered in this book? Stephen Hawking takes you on this virtual tour where he talks about different topics, combines philosophies and scientific explanations, and does everything. But he doesn’t answer all these questions directly. So you won’t get a ready-made answer to all these questions. At the end of the chapter, you will understand everything, and everything will be pretty clear to you, whatever he wanted to explain. What I love about the book is that the personality of Stephen Hawking comes across, and you enjoy reading it. It’s such a beautiful right to read this book. Also, it shows that he was a very humorous person and funny because many times in this book, he gets into this self-deprecating humor thing. Stephen Hawking discusses a grand unified theory in a brief history of time. The idea behind a grand unified theory is that laws can connect general relativity and quantum mechanics. It is also sometimes called the theory of everything.

Seven Brief Lessons on Physics by Carolo Rovelli; translators Simon Carnell and Erica Segre (UK : Allen Lane, an imprint of Penguin Books, 2015). Call number: PSE Library QC24.5 C38 2015 My reason for being sceptical is that I assumed this book would be a fairly watered-down affair with the usual dose of hand-wavy analogies that end up obscuring or misconstruing most of the real physics. Well, I was very wrong!

i.e.) the very boundary of the observable universe is also 2D surface encoded with info about real 2D object. A jaunt through space history . . . with charming wit and many pop-culture references' – BBC Sky At Night Magazine Gravity! The Quest for Gravitational Waves by Pierre Binétruy (Oxford: Oxford University Press, 2018). Call Number: PSE Library QC178 .B56 2018 Also, as a reader who is not using these texts for any academic purposes, I think Cox’s writing is so much easier to ‘digest’ (and much more enjoyable in general) than Hawking’s (only comparing this to a few of Hawking’s books that I’ve previously read). I think it might be important to clarify that – I’m not comparing them based on ‘who’s the better (astro)physicist’ or whose ‘work’ was more ‘important’; but only of whose writing/books I had found more ‘enjoyable’. Hope that helps? The issue with today's small pop science books is that they don't intend to provide coherent information about something but for commodifying the simplified works of complex minds to the public under the pretext of preaching that knowing the name of something is intelligent rather knowing about something and being able to clearly understand it.
