The mushroom is called Reishi or Mannentake (10,000 year mushroom) in Japan, and Ling Chi or Ling Zhi (herb of immortality) in China and Korea. Ganoderma is known from Chinese medical writings from over 2,000 years ago and it is a popular symbol and subject in Chinese art. Reishi mushrooms are found worldwide in tropical and subtropical climates.
Nuclear Technologies History Part 2 - Splitting the Atom. 1  Fermi knew that when an atom splits it releases other neutrons, and he was quick to realize that under the right conditions those neutrons could go on to split other atoms in a chain reaction. This would lead to one of two things: a steady generation of energy in the form of heat or a huge explosion. If each splitting atom caused one released neutron to split another atom, the chain reaction was said to be critical and would create a steady release of heat energy.
How Fusion Works. Fusion is the opposite of fission: while fission is the splitting of a heavy nucleus into lighter nuclei and the release of energy, fusion occurs when two light nuclei are forced together to form one heavier nucleus. Since the single heavier nucleus has a lower energy that the two separate nuclei, energy is released.
