You are thinking between this edition or another. I can comfortably recommend this edition. Despite being a free one it has not gramatical errors and the formatting is enough comfortable. My only objection is the page count, it is supposed to be 280 pages long and maybe so if each page is a newspaper page, this book is rather a 550 to 600 pages book; one page seems to imply there are graphs about formules but I could be wrong; there is a long introduction (10% of the reading progress) but non of them detract me to recommend, this is a good enough edition.
About the content itself: is known that Intelligence has its limits, a dog will learn till some point and no more. Each human has a limit too and I wondered how it would be to meet a superior intelligence: not anymore! These three books are the closest I have been of such vast intellect, Poincaré has his limits too, but they go beyond most of us. I understood the complex themes that were written, but only by recalling my differential calculus and and descriptive geometry. I believe only a person that truly understands a particular theme will be able to explain it clearly. In this book that contains three books Poincaré gets to explain so much about science, he imagines alternative worlds, skews the laws of the universe, teaches amazing and epic chapters of voyages of scientific discovery, he speaks about dimensions, gets inside the core of science and explores the limit of the mathematics of his time not as a journalist but as one of the main protagonists... Is quite fascinating! There are some parts that mention complicated mathematical procedures without images, which is notorious in the chapters about geometry, but they are clear and they afterwards are quite useful to understand what is explained and questioned about light, time and relativity. I miss books like these for science, these days it is rather journalism and activism rather than discovery.
As it is a public domain edition Poincaré wrote these books more than a century ago, but there are not many changes... the principles he mentions still exist today with another names, similar but able to perform more accurate predictions. Some have changed name, analysis situ now is topology. In a time were supposedly the belief was that the milky way was the whole universe, the neutrons had not even name and the light traveled through ether; is interesting to read that there was a safe guess that nebulosas where other galaxies, that neutrons and electrons could exist in the way it is taught now, and that ether could disappear and it wouldn't matter because science at its foundation is meant to be this way. Poincaré writes that each old piece of knowledge that is outdated helped to reach the contemporary science of his time; his thesis is proved to be right because many paradigms away what he writes still has application to understand the reality today and the principles we use. An extraordinary book indeed!
