What is the history of nuclear fusion?

What is the history of nuclear fusion?

Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy. Its history dates back to the early 20th century.

Who were the key scientists involved in its development?

Key figures include Hans Bethe, who explained the fusion process in stars, and Edward Teller, who contributed to fusion research for weapons.

What were the major milestones in fusion research?

Major milestones include the first controlled fusion reaction in 1952, the development of tokamaks in the 1960s, and recent advancements in laser fusion.

How does nuclear fusion differ from nuclear fission?

Fusion combines light nuclei and releases energy, while fission splits heavy nuclei. Fusion produces less radioactive waste than fission.

What are the current challenges in achieving practical nuclear fusion?

Challenges include achieving the necessary temperature and pressure for sustained reactions, as well as developing materials that can withstand extreme conditions.
