1. The study of electricity began with Dr. Gilbert. 2. He lived at about the same time as Galileo. 3. In 1600 he wrote a book describing experiments on electricity and magnetism. 4. Russia played an important part in the development of electrical science. 5. In spite of difficult conditions under which the scientists and inventors had to work in tzarist Russia they discovered electrical phenomena of great importance. 6. In addition to that Russian scientists and inventors always tried to find practical application for the phenomena discovered. 7. The first work on electricity published in Russia was that written by the father of Russian science Lomonosov. 8. Lomonosov was the first to find that heat, light and electricity are different forms of movement. 9. He was also the first to find the electrical nature of some atmospheric phenomena. 10. Academician Petroff was the first scientist in the world who observed the phenomena know later as the electric arc.
