The Atomic Bomb DropNeiffer’s World Cultures @ Capital HS
Why does the US develop the bomb?August, 1939: Albert Einstein (formerly of Germany) writes FDR
He argues that the US is well behind Nazi Germany on the development of nuclear weapon.
WAS GERMANY ACTUALLY DEVELOPING “THE BOMB?”
Yes, but...
1. Germany lacked scientists
2. Hitler didn’t want it
It is a waste of German
resources...make more rockets!
FDR orders the development of nuclear weapons as a defensive measure.

A MINI LESSONS IN NUCLEAR SCIENCE...
Three types of nuclear damage...
Three types of nuclear damage...Pressure Damage – Damage from the force of the bomb (heat, light, etc.)

Nuclear Winter – particles thrown up into atmosphere…blocks sunlight, plants and animals die
SADLY, MOST EFFECTS?ESTIMATED...

NEW YORK CITY
A 150 kiloton bomb constructed by terrorists is detonated in the heart of Manhattan, at the foot of the Empire State Building. The bomb goes off without warning at noon time. It's a clear spring day with a breeze to the east.Assumptions:
There is no warning. The population has not been evacuated nor sought shelter. Both measures could reduce casualties.There is clear weather, with visibility of 9 miles (16 km).This is an isolated attack, leaving the rest of the country free to respond.A large percentage of the day time population is outside - 25%.The daytime population density is roughly uniform and about 125,000 per square mile.The shock wave will spread out uniformly in all directions, being minimally affected by structures.
