The document discusses the development of weapons of mass destruction, particularly nuclear weapons, in the 20th century. It notes that physicists led by J. Robert Oppenheimer created the atomic bomb, which killed over 100,000 people in Japan. The document includes quotes from theoretical physicist Freeman Dyson, who took part in nuclear weapons development and acknowledges the "illusion of illimitable power" it can provide scientists, which he calls "technical arrogance." Dyson warns that human nature may become corrupted when the great powers of science and technology become apparent, and that humanity must rein in the vanity and arrogance such power can unleash to avoid destroying the world.

1. 20TH CENTURY

2. The world has developed technologies underlying the
weapons of mass destruction (WMD) – nuclear, biological and
chemical (NBC). They were powerful weapons that pose an
enormous threat to warring nations.

3. Physicists led by J. Robert Oppenheimer
brought into existence a deadly nuclear weapon
that killed over a hundred thousand people.
The atomic bomb was a definite testament to the
success of science and technology but it also was a
fatal reminder of how destructive science and
technology can be.

4. FREEMAN DYSON

5. Freeman Dyson,
Theoretical physicist and mathematician
in the documentary The Day After Trinity, shared his thoughts and sentiments as a scientist
taking part in the development of nuclear power:
The glitter of nuclear weapons- it is irresistible if you come to them as a scientist. To feel it is
there in your hands, to release this energy that fuels the stars, to let it do your bidding. To
perform these miracles, to lift a million tons of rocks into the sky – it is something that gives
people an illusion of illimitable power, and it is, in some ways, responsible for all out
troubles. This, what you might call technical arrogance - that overcomes people when they
see what they can do with their minds.

6. Human nature may be corrupted when the powers of our mind, our
rationality, and our science and technology become obvious.
If humans were not able to rein in the vanity and arrogance that such
power unleash, then they are on the way to destroying the world.
