Hemp seeds, or hemp hearts, have a high nutrition profile and are a healthy addition to most diets. Hemp seeds are the seeds of the same plant as marijuana, the cannabis plant, but they do not contain high levels of THC and will not get you high.
Nuclear explosion. Atomic bomb explosion. A nuclear explosion is energy being released from a very fast nuclear reaction. It can be caused by nuclear fission, nuclear fusion, or both. Atmospheric nuclear explosions are associated with mushroom clouds, although mushroom clouds can occur as a result of large chemical explosions.
Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei. The process may take place spontaneously in some cases or may be induced by the excitation of the nucleus with a variety of particles (e.g., neutrons, protons, deuterons, or alpha particles) or with electromagnetic radiation in the form of gamma rays.
