Science books in general, and more specifically Science History is possibly my favourite non-fiction genre. I admit, there are times when I feel that I am a little out of my depth on some of the topics. But I still love reading the jargon, and the eventual conclusions of theories that I don't understand.
Gravity's Arc had me feeling like that. It does a great job of describing the evolution of Gravity as a concept from Aristotle's days to the present (I don't think Scientists even call it Gravity these days - at least not in the sense Newton meant it). And it's truly fascinating. The author does talk up Aristotles era of science, but it's hard to not find their thoughts stupid. There. A present-day nobody calling a world renowned thinker like Aristotle Stupid. But seriously, you should read what he thought of gravity.
It turns out that ideas about Gravity pretty much languished till Newton came along. There were breakthroughs far and wide though... like ideas of Sun Centered solar system that led scientists to ask questions about Gravity. But formal laws and equations came along with Newton. And that is what we learnt in school. However, there were some major holes in Gravity. A big question remained, one that I myself had in school, how in the world does Gravity act over a distance and instantaneously? Well, as a school kid, I wasn't really enterprising enough to discover answers to such lofty questions. After all, getting 40/40 in the exam was more important then. But Einstein, among others continued probing, and came with answers of space-time curvatures that cause Gravity. From there on, the book becomes really complicated. While the language used was still lucid, the topic became a little too heavy. General, high level explanations ended up providing about .01% of half-knowledge of the science involved. Understandably so. I anyways didn't want a book filled with complex equations. Nonetheless, the general idea was fascinating enough.
Considering relativity and modern concepts of space-time have been around since 1930s, I wish somebody had atleast briefly taught these things to me in the first 12 years of my general science education. While at a day-to-day level you don't need to know anything about such scientific ideas and reasonings of how the world works, but personally, I'd have liked to know.
For now, that's where books like these come in. I found it a fun read.
