Excellent read, I had always wondered; and now I know.<br><br>It’s a total nerd book, if you love math at the conceptual level, enjoy history, and the engineering aspect of how things came to be- this is a great book.  I’m a network engineer, wife turned me on to this book from her college days - she was a math major. Well written, decently paced given the subject matter, and enlightening.<br><br>If none of the above interests you, the book may also be used as a soporific.
