Zaijing Sun In The News

Seven years after the end of WWII, the US detonated the world's first hydrogen bomb.
H-bombs use a combination of nuclear fission and fusion and are far more powerful than atomic bombs.
The world's first nuclear weapon — the atom bomb — devastated the Japanese cities of Hiroshima and Nagasaki in 1945.
With its depiction of the first atomic bomb explosion, the new film, "Oppenheimer," highlights the massive destructive power of these early nuclear weapons.
