This site has been prepared in support of my book The Physics of the Manhattan Project(Springer). Below are links to spreadsheets referenced in the text and to a pdf document giving the algebra of the Bohr & Wheeler derivation of Chapter 6; scroll down if need be. Click here for a pdf document that gives brief descriptions of the spreadsheets. The "Reflected Core" spreadsheet has been added after publication of the book. And here you you will find a copy of the Table of Contents. I would be happy to receive any suggestions for corrections or improvements. Here is a link to the Amazon page, and one to B&N. Links to annotated bibliographies of Manhattan Project literature also appear below. Finally, what would a book on nuclear weapons be without a list of errata (last update November 27, 2011)?
Special Note: My synoptic treatment of the Manhattan Project, tentatively titled "The Science and History of the Manhattan Project", is scheduled for release by Springer in late 2014. This will be a lower-undergraduate level text aimed at physics and general-science students, but will also contain extensive descriptive material that will make it suitable for interested lay readers. A tentative draft outline - subject to change - is available here.
