1. Hiroshima and Nagasaki By Jenny, Jessica and Susannah

2. 3 Big Ideas • Manhattan Project • Significance of Bombing • Why?

3. Code Name: Manhattan Project

4. Einstein: Dear President Roosevelt •  Scientists:  • Oppenheimer • Bohm  • Fermi  • Szilard •  Research: Oak Ridge • 1st test: July 6, 1945

5. Test Weapons • "Little boy": Uranium- 235 • "Fat man": Plutonium- 239

6. The atomic bombing •  August 6, 1945: Hiroshima •  August 9, 1945: Nagasaki

7. In response to • Pearl Harbor • preemptive attacks

8. Surrendered • After radioactive fallout • Hirohito, Emperor

9. Little Boy • 9,700 pounds • directly killed 194,566,000 people • destructive force 63 Tera-Joules 

10. Nuclear Fission •  The atom splits •   critical mass- fissionable materials needed

11. Fissionable Materials •  start with U-235, U-233, Pu-239 • formed isotopes U-235= U-236= Kr-92+ Ba-142 •  U-235 + 1 neutron= 2 neutrons + Sr-92 + Xe-140+ Energy

12. Nuclear Chain Reaction • Atom bombarded with nucleus  • process continues and triples • sustained by neutron

13. Nuclear Weapon • Primarily use Plutonium, Uranium • USA, United Kingdom, France, China, Russia N.P.T
