What are Vaccines? By Dr Ananya Mandal, MD. There are several diseases like Diphtheria, whooping cough (pertussis), measles, mumps, Yellow fever, small pox and German measles (rubella) that are unfamiliar to many these days.
nuclear energy energy that can be liberated by changes in the nucleus of an atom (as by fission of a heavy nucleus or by fusion of light nuclei into heavier ones with accompanying loss of mass).
Nuclear fusion is where the energy is released when the nucleus of the atoms are combined or fused together to form a large atom. This type of energy production is part of the future because of the cost of hydrogen power plants. The sun produces this type of energy. Nuclear fission is the splitting of atoms to form smaller atoms, releasing energy. Nuclear power plants use this type of nonrewable energy to produce energy by splitting atoms that are easily split like uranium.
