He was very sensitive and was able to look after the scientists well so that they would cooperate in the team.
Plutonium bomb or enriched Uranium
They arranged in a sphere and put explosives on the outside to trigger an 'implosion'.
Heisenberg was quite close to building a bomb.
They sent Haukelid to blow up the ferry that transported the heavy water from the remote factory to the mainland.
As Germany was losing , the country lost its industrial resources to pursue the bomb construction.
He was briefly imprisoned but released and he continued his scientific career.
He was put under surveillance because the authorities feared that he had worked with Communist Russia.
Should we use this terrible weapon or just use it as a threat?
The President's advisor was 'old-fashioned', saying the army builds bombs in order to use them.
A chain reaction of enriched Uranium, transforming mass into energy
For maximum effect on the surface because triggering on the ground would have absorbed much energy
The sun and to conditions shortly after the big bang
Several million degrees Celsius
Heat wave, near vacuum creating a storm of several hundred kilometres per hour, plus radioactive fallout
How the equation controls how stars 'work' and how life will end.
The sun is made up of 66% iron.
Every element gives off a distinct visual signal: spectroscope breaks the spectrum of electromagnetic radiation into various wavelengths
University of Cambridge (England), no doctorate for women, went to Harvard, wrote a Ph.D.
She re-interpreted the spectroscope lines (different amount of ionization at different temperatures): the sun consists mostly of Hydrogen
They didn't believe it at first, but four years later it became accepted.
4 Hydrogen atoms fuse to one helium atom, releasing lots of energy in the process
How were the different elements on earth created?
Implosion of stars create immense temperatures, squeeze larger nuclei of elements together
Atomic bomb design (implosion of Plutonium bomb)
Radioactive blasts at the core of the earth, high temperatures which lead to continental shifts and earthquakes
Atomic bomb, submarines, reactors (power stations), smoke detectors, glowing exit signs, PET scans, C-14 clock (archaeological dating)
Hydrogen will burn out in 5 billion years, helium sun expands, too hot on earth, Helium will burn out, Earth will cool, and the sun will lose its gravitational pull, earth will fly away
Black hole
Earth will fly away from sun and be swallowed up by a black hole.
