Plutonium was prepared for the first time in Berkeley, USA at 14.12.1940.
The vast majority of nuclear weapons use Plutonium as at least part if not all the fission fuel. No specific scientist first suggested it, it was just obvious once the element was discovered to in cyclotron experiments.

The rivalry (in the 16th century) concerned the issue of which country could claim and exploit which part of the newly discovered Americas and other parts of the world newly discovered or yet to be discovered. The issue was settled by mutual consent by the Pope, who divided the map of the world in a Spanish and a Portuguese sphere of influence and colonization, where the other party had to stay out of.
Ozone hole is discovered over Antarctica. It is because of the low temperatures.
Plutonium is a radioactive element that decays over time, transforming into other elements through a series of radioactive decays. When plutonium decays, it releases energy in the form of radiation and transforms into a different element. This process continues until the plutonium is no longer present.
Abel Tasman discovered the country of New Zealand in 1642. He also discovered the island of Tasmania, which is now part of Australia, but he believed New Zealand and Tasmania to be part of the same continent.
