Dnf. I was expecting an emphasis on the biographies of inventors but instead the emphasis was on how the inventions worked, sometimes without any reference to the inventor.
This book is a very old one and so most of the invention that are talked about in this book like steam engines, hot-air balloons etc are now well obsolete. But the stories about them are interesting. So if you want to know about old invention this can be a good read.
