10
Q
What kind of physics did Oppenheimer study?
A
Theoretical physics
11
Q
What alarming discovery did Otto Hahn make?
A
That if you speed up neutrons enough and they hit uranium atoms hard enough, the atom would split in two
12
Q
What did Hahn’s former partner, Lise Meitner, and her nephew, Otto Frisch, compare this new phenomenon to?
A
They compared the atom nucleus to a liquid droplet, like Niels Bohr did, that could stretch until it split into 2 “droplets”, if hit hard enough by a speeding neutron
13
Q
What happens when atoms split?
A
They release energy, and if you split many atoms at once, it would create enough energy to make the most powerful bomb ever

Q
What did physicists call the splitting of an atom?
A
Fission
15
Q
What were physicists so afraid of with the discovery of fission?

A group of military leaders and scientists whose goal was to figure out the basics of building an atomic bomb
19
Q
How did Harry Gold get into spying for the Soviets?

The plutonium expanded in the heat, so they waited for it to cool and shrink back down to it's original size
95
Why was Oppenheimer so concerned about the weather around the time of the test?

116
Why did Truman not want Japan to keep their emperor as long as they surrendered?
The United States had demanded an unconditional surrender since Pearl Harbor and Truman thought it would be a betrayal of US troops to accept anything less and it would make him look weak politically if he negotiated with Japan
117
What did dropping a second bomb in less than a week indicate?
That the US had an endless supply of atomic bombs
118
What was the nickname of the second bomb and what was different about it from the first bomb?

August 29, 1949
127
How did the U.S. intelligence discover that information had been stolen from the Manhattan Project?
They cracked the Soviet code in 1949 and when they decoded telegrams during the war sent to the KGB, they discovered a note with information that could only have come from inside the project.
128
Why couldn't the coded Soviet telegrams be used in court as evidence against Fuchs?
The Americans didn't want the Russians to know that they had broken the Russian code
129
How did the British get evidence against Fuchs?
They kept hounding him until he caved under the pressure and confessed
130
Why did Fuchs get just 14 years in prison instead of the death sentence for handing over secret information to Russia?
Because Russia was an ally to Great Britain during the war, not an enemy
131
What happened to Fuchs after sentencing?
He was released after 10 years for good behavior, move to East Germany, got married, and continued atomic research until his death in 1988 at the age of 76
132
What crucial mistake did the KGB make five years before Gold was caught?
In 1945, they had Gold pick up information from both Fuchs and David Greenglass, which cross-contaminated two separate spy rings, allowing the US to catch more Soviet spies
133
What was the most famous espionage trial of the century and why was it significant?
The trial of Julius and Ethel Rosenberg, who recruited Greenglass. The trial exposed many more names of Soviet agents and the Soviets were never as effective in spying on America. It also started the Red Scare of the 1950s
