Genre: science – physics
A beautifully written book about our universe and how and why it was designed. It’s written for people of many different levels of knowledge of physics already, from short and clear explanations of atoms to mentioning a few things I personally need and want to look more into like string theory, bosons, where plancks constant comes from and Feynmans sum over histories. This is a book trying to give philisophical answers based on scientific history and theories. As the book says itself:
“Why is there something rather than nothing?
Why do we exist?
Why this particular set of laws and not some other?”
Rating out of five: five
I’ve honestly never read a full Stephen Hawking book, even though I take physics classes and am very interested in it. I was personally really surprised at how much I understood, that I’ve gone through in classes before and this book looked more at the “why” behind it, the connection that I so much love. This is the book you need to read if you’re interested in the how and why’s of the universe, no matter what level of understanding you’re at now!
This book absolutely made me reflect on the nature of the universe, even though I already have some experience there. It also made me so very excited about learning more, and what we could find out in the future, with newer technology. Multi-verse and possibly no objective reality existing are examples of rabbit-holes of information and theories I love to fall into, so this book was ideal.
“While concending that human behaviour is indeed determined by the laws of nature, it also seems reasonable to conclude that the outcome is determined in such a complicated way and with so many variables as to make impossible in practice to predict.”
“[…] philosopher David Hume who wrote that although we have no rational grounds for believing in an objective reality, we also have no choice but to act as if it is true.”
“Such calculations show that a change of as little as 0.5 percent in the strength of the strong nuclear force, or 4 percent in the electric force, would destroy either nearly all carbon or all oxygen in every star, and hence the possibility of life as we know it. Change those rules of our universe just a bit, and the conditions for our existence disappear!”
“If the [M-] theory is confirmed by observation, it will be the successful conclusion of a search going back more than 3.000 years. We will have found the grand design.”
