Scientist and his inventionEvery good scientist should cherish his invention. It is important for a scientist to obtain a patent for an invention. A scientist must have a new discovery. The scientist usually writes a Ph.D. or doctoral thesis. Scientists can not rewrite information from other sources. The scientist must write a unique text. To check the uniqueness of the scholar\'s texts there is a special program. The work of the scientist is very hard, but it\'s worth it.
