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.
Nuclear Fission: Fission is the splitting of a large atom into two or more smaller ones. Fission reaction does not normally occur in nature. Critical mass of the substance and high-speed neutrons are required. It takes little energy to split an atom in a fission reaction. The energy released by fission is a million times greater than that released in chemical reactions, but lower than the energy released by nuclear fusion. Fission is used in nuclear power plants. Uranium is the primary fuel used in power plants. Nuclear Fusion: Fusion is the fusing of two or more lighter atoms into a larger one. Fusion occurs in stars, such as the sun. High density, high temperature environment is required. Extremely high energy is required to bring two or more protons close ...
