The advancement of human civilization is possible just because of enormous contributions made by scientists. They are one of the most influential people of today’s world. With practical advantages in engineering, medicine and technology, they have helped us to grow better understanding about the world and different working phenomena that govern us. Their names are remembered in the sands of time for their work in the welfare of mankind with different inventions that has made our modern lives easy. Here is a list of the four great scientists we’ve ever seen who changed the world.
Louis Pasteur (1822—1895)
Pasteur contributed greatly towards the advancement of medical sciences developing cures for rabies(狂犬病),anthrax and other infectious diseases. He also invented the process of pasteurization(加热杀菌法) to make milk safer to drink. He probably saved more lives than any other person.
Otto Hahn (1879—1968)
Hahn was a German chemist who discovered nuclear fission(裂变) in 1939.He was a pioneering scientist in the field of radio-chemistry, and discovered radioactive elements in 1921.He was awarded the Nobel Prize for Chemistry in 1944.
Nikola Tesla (1856—1943)
Tesla worked on electro-magnetism and AC current. He obtained around 300 patents worldwide for his inventions from electricity to radio transmission, but many inventions developed by Tesla were not put into patent protection. He played a key role in the development of modern electricity.
James Clerk Maxwell (1831—1879)
Maxwell made great progress in understanding electro-magnetism. His research in electricity and kinetics laid the foundation for quantum(量子)physics. Einstein said of Maxwell, “The work of James Clerk Maxwell changed the world forever.”
