The temperatures necessary for fusion reactions are extremely high. Reactions of this kind are believed to be the source of the energy of the stars (including the Sun).
___________________	3. A nuclear reaction in which a heavy atomic nucleus (e.g. uranium) splits into two approximately equal parts, at the same time emitting neutrons and releasing very large amounts of nuclear energy.
___________________	4. The positive electric charge on the nucleus of an atom. Numerically it is equal to the atomic number of the element, to the number of protons in the nucleus, and to the number of electrons surrounding the nucleus in the neutral atom.

16) Titles: Analog Computer; Computer; Digital Computer; Central Processing Unit.

___________________	1. The central electronic unit in a computer which processes input information, and information from the store, and produces the output information. This unit and the store form die central part of the computer.
___________________	2. A computer in which numerical magnitudes are represented by physical quantities such as electric current, voltage, or resistance.
___________________	3. An electronic device which accents data, applies a series of logical processes to it, and supplies the results of these processes as information. The device is used to perform mathematical calculations at a very high speed. This makes them useful for various purposes, such as office calculations, control of industrial processes, and the control of flight paths.
___________________	4. A computer which operates on data in the form of digits rather than the physical quantities.
