2. Multiplexed Information Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He formulated the Periodic Law, created his own version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered. 8 February 1834 – 2 February 1907

3. Dmitri Mendeleev was born in the village of Verkhnie Aremzyani, near Tobolsk in Siberia. His parents were Ivan Pavlovich Mendeleev and Maria Dmitrievna Mendeleeva. His grandfather was Pavel Maximovich Sokolov, a priest of the Russian Orthodox Church. D. Mendeleev was raised as an Orthodox Christian. His mother encouraged him to "patiently search divine and scientific truth." Childhood

4. In 1849, his mother took a small boy across the entire state of Russia from Siberia to Moscow with the aim of getting D.Mendeleev a higher education. The university in Moscow did not accept him. The mother and son continued to St. Petersburg where D.Mendeleev entered the Main Pedagogical Institute.

7. Progress Metrology: D. I. Mendeleyev was the predecessor of modern metrology, in particular - chemical metrology. He is the author of row of works on metrology. He created the exact theory of scales, worked out the best constructions of yoke and catch, offered the most exact receptions of weighing.

8. Progress Periodic table: In 1863 there were 56 known elements with a new element being discovered at a rate of approximately one per year. Other scientists had previously identified periodicity of elements. On 6 March 1869, D. Mendeleev made a formal presentation to the Russian Chemical Society, entitled «The Dependence between the Properties of the Atomic Weights of the Elements», which described elements according to both atomic weight and valence.

9. Progress Periodic table: D. Mendeleev published his periodic table of all known elements and predicted several new elements to complete the table. Some people dismissed D.Mendeleev for predicting that there would be more elements, but he was proven to be correct when Ga (gallium) and Ge (germanium) were found in 1875 and 1886 respectively, fitting perfectly into the two missing spaces.

10. Monuments There are monuments to D. Mendeleyev not only in Russia but also all over the world. People will always remember the man who made an enormous contribution to science.
