How Much Coffee Did Feigenbaum Drink? . I was going to wait until I finished reading this book to review it - seeing as how I still have 100 pages to go - but I'm not sure if I'll be able to ever finish it. The book spends A LOT of time telling you the back story about how certain achievements were made in the field of science, but when it finally comes time to report the results of those achievements, the reader is only partially satisfied. Very little actual science, and a lot of biographical information. I was hoping it would be the other way around. If you're interested in reading biographies of scientists you've probably never heard of, this is definitely the book for you. Why would I give a book I didn't finish 2 stars? Because I did pick up a few interesting mathematical tidbits from the sections I read. I just didn't pick up enough tidbits to keep me going. The universal constant is interesting, and the cross section of the chaotic 3-D graph is interesting too. Great for scientific history buffs, but those looking for application for personal use, forget it
Output:
NEG
