MICHAEL FARADAY

1. Michael Faraday, the English experimental physicist, was born in 1791 in a poor family. The boy began to work as an apprentice at a bookbinder’s shop at an early age. One day a man entered the shop and found the boy studying an article on electricity. The man was surprised to see a boy so interested in such a difficult subject and gave him four tickets for the lectures at the Royal Institutions.

2. The boy went to the lectures and made notes of what he heard. At the end of the lecture he came to Sir Humphry Davy, the great English scientist, and showed him his notes. Davy was surprised. Later he made Faraday his assistant and helped him in his education.

3. Faraday had many important discoveries. Among his works are the concept of the magnetic field and the magnetic “lines of force”, production of new kinds of optical glass, and research on electrolysis.

4. Faraday produced the first mechanical motion by means of a permanent magnet and an electric current. This is the principle upon which the modern electric motor is based.

5. Faraday was very modest and he loved his work more than honours. He refused to become President of the Royal Society and also refused to be knighted.

DMITRY IVANOVICH MENDELEYEV

1. Dmitry Ivanovich Mendeleyev is a famous Russian chemist. He is best known for his development of the periodic table of the properties of the chemical elements. This table displays that elements' properties are changed periodically when they are arranged according to atomic weight.

2. Mendeleyev was born in 1834 in Tobolsk, Siberia. He studied chemistry at the University of St. Petersburg and in 1859 he was sent to study at the University of Heidelberg. Mendeleyev returned to St. Petersburg and became Professor of Chemistry at the Technical Institute in 1863. He became Professor of General Chemistry at the University of St. Petersburg in 1866. Mendeleyev was a well-known teacher, and, because there was no good textbook in chemistry at that time, he wrote the two-volume “Principles of Chemistry” which became a classic textbook in chemistry.

3. In this book Mendeleyev tried to classify the elements according to their chemical properties. In 1869 he published his first version of his periodic table of elements. In 1871 he published an improved version of the periodic table, in which he left gaps for elements that were not known at that time. His table and theories were proved later when three predicted elements: gallium, germanium, and scandium were discovered.

4. Mendeleyev investigated the chemical theory of solution. He found that the best proportion of alcohol and water in vodka is 40%. He also investigated the thermal expansion of liquids and the nature of petroleum.

5. In 1893 he became director of the Bureau of Weights and Measures in St. Petersburg and held this position until his death in 1907.

6. Перепишите следующие вопросы к тексту и письменно на них ответьте.

1) What is Mendeleyev best known for?

2) When was his first version of the periodic table of elements published?

3) Which three elements were discovered later?
