Does anyone know where I can learn about the different parts of the Manhattan Project?
One can google on "Manhattan Project".
But try - http://www.fas.org/irp/ops/ci/docs/ci2/2ch1_f.htm
One can always fall back to Wikipedia - http://en.wikipedia.org/wiki/Manhattan_Project - but verify the information with other sources.
There were different sites:
Berkeley Labs where Lawrence and his group were using cyclotrons for enrichment.
Handford where Pu was being manufactured via neutron activation of U-238.
Oak Ridge using gaseous diffusion for enrichment.
I think MIT's Rad Lab was part of it.
Also, if you're curious about some of the people involved in the project, Brotherhood of the Bomb by Gregg Herken is a good read.
That's a excellent book.
