5 Must Know Facts For Your Next Test

  1. Sakharov played a key role in the Soviet Union's development of the hydrogen bomb, known as the 'Tsar Bomba,' but later regretted his involvement due to the destructive potential of nuclear weapons.
  2. In the 1960s, he became a vocal advocate for human rights, particularly in opposing government repression and promoting civil liberties in the Soviet Union.
  3. Sakharov was awarded the Nobel Peace Prize in 1975 for his efforts to promote peace and his stance against nuclear proliferation.
  4. His advocacy led to his exile in 1980, where he continued to write and campaign for human rights until he was allowed to return to Moscow in 1986.
  5. Sakharov's work on thermonuclear physics contributed to the understanding of plasma behavior, which is crucial for developing effective magnetic confinement systems for fusion energy.
