      Working on my book (steady progress lately...) — one graph I'm fairly pleased with at the moment: a combined cost and personnel graph for the entire Manhattan Project (1942-1946). Really lets you see how "big" it was at any given point, by a variety of metrics.pic.twitter.com/pupn8PMR7G

      One little thing that blows my mind: on average, the Manhattan Project lost about 19% of its constructional personnel and 7% of its operations & research personnel per month because people quit, got fired, etc. So those big monthly gains are even larger than they look...

      A long with the gigantic scale of the project, the speed at which it all occurred is still staggering. What like basically 2-3 years tops

      Pretty much 3 years to a bomb from their initial commitment to making one — summer of 1942 to summer of 1945. Still fastest nuclear program ever, though they started it with a totally incorrect idea of how hard it would be, and thought they'd be done in 1944...

          Any official accounting of project related accidental deaths? I think Groves put it at 8 deaths in his book, but unclear if that was only factory operation death, and not total deaths.pic.twitter.com/LGg1bOPFGD

          The AEC later (1975) tallied 80 fatalities during the MED period, at all facilities. Most very banal.pic.twitter.com/SMRrr1nrQw

          Wow 80 is a lot more. But guess deaths on large project was kind of expected back then. How ironic that Groves Fatality Number Of 8 was off by a factor to 10!

          The records the Manhattan Project people kept showed that their injury/fatality rate was more or less par for the course (maybe even a little better) than other industrial projects. Very few of the deaths had anything to do with the "special" nature of the project.

          Makes one ask why? Groves claimed safety due to top notch contractors E.g. DuPont w/ experience in munitions works, etc Other claim extra scrutiny of security, others claim cleanliness requirements of project. Maybe all of above. Any thoughts on the why?

          They did put a lot of effort on it. Groves knew how to manage large projects — it was what he brought to the job. He wanted things done quickly but not stupidly, and he cared about postwar accountability quite a lot more than many realize.

          One thing I like to point out sometimes: Groves strongly believed in workers having time off on the weekend. He understood that what you might gain from extra hours would be more than lost in morale, mistakes, exhaustion, etc.
