The Ascent of Gravity: The Quest to Understand the Force that Explains Everything by Marcus Chown (London Weidenfeld & Nicolson, 2017). Call Number: PSE Library QC178 .C295 2017 A singularity is what you end up with when a giant star is compressed to an unimaginably small point."

Title summary: “Discusses the concept of gravity from its earliest recognition in 1666 to the discovery of gravitational waves in 2015, and explains why gravity holds the key to understanding the nature of time and the origin of the universe.” You can learn about Einstein and how Einstein was the first to think about reality differently and how that led him to write his theory of relativity and everything. The author closes this book with a chapter on his philosophical view concerning science and humanity. Stephen William Hawking was born on 8 January 1942 in Oxford, England. His parents' house was in north London, but during the second world war Oxford was considered a safer place to have babies. When he was eight, his family moved to St Albans, a town about 20 miles north of London. At eleven Stephen went to St Albans School, and then on to University College, Oxford, his father's old college. Stephen wanted to do Mathematics, although his father would have preferred medicine. Mathematics was not available at University College, so he did Physics instead. After three years and not very much work he was awarded a first class honours degree in Natural Science.

Quantum Fuzz: The Strange True Makeup of Everything Around Us by Michael S. Walker (Amherst, New York : Prometheus Books, 2017). Call number: PSE Library QC174.12 .W347 2017 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. A lyrical science communicator’: Carlo Rovelli. Photograph: Roberto Serra/Iguana Press/Getty Images This is definitely a hard read. I had to read some chapters again and again to understand ( not fully though). So if you are going to read this book, and understand it thoroughly, you should spend some time on it.The more accurately you know the positions of particles, the less accurately you can know their speeds, and vice versa" 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. 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. Quantum mechanics implies that the whole space is filled with pairs of virtual particles and antiparticles, which are constantly materializing in pairs, separating, and then coming together again and annihilating each other. 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! 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 best discovery in this whole matter, I guess, is; "During most of the life of a normal star, over many billions of years, it will support itself against its own gravity by thermal pressure, caused by nuclear processes which convert hydrogen into helium."The first sign I was wrong is when I noticed a myriad of Penrose diagrams throughout the book - that is not something I’ve see in popular science books before. Sometimes you will get spacetime diagrams and usually very simple ones at that. As someone who studied physics 20 years ago as an undergraduate (and took a subject on relativity) I can honestly say I’d never seen a Penrose diagram before and I found them a really useful learning tool in the book. As I said, I’ve read a lot of books on this topic and adjacent ones (Thorne, Greene, Smolin, Carrol, etc) and I was genuinely glued to this one.
