Google doodle honors periodic table creator Dmitri MendeleevFebruary 8, 2016 - 07:54 AMT PanARMENIAN.Net - Google has marked the 182nd birthday of Russian chemist Dmitri Mendeleev, who invented the periodic table, with one of its trademark doodles. Born in 1834 in Siberia, Mendeleev studied at the Main Pedagogical Institute, before writing a book on the inner workings of the spectroscope - an instrument that measured light's properties across the electromagnetic spectrum, the Mirror reminds. He went on to work as a professor at both the Saint Petersburg Technological Institute and the Saint Petersburg State University. His textbook Principles of Chemistry, regarded as a milestone study, was published in two volumes in 1868 and 1860. In 1869 he published his Periodic Table, listing 63 elements in rows or columns in order of atomic weight. He claimed the idea came to him in a dream. Mendeleev also wrote about mixing alcohol and water, which led to vodka being a standard 40 per cent. He died of flu in Saint Petersburg at the age of 72. A crater on the moon is named after him, as is element number 101, radioactive Mendelevium. After years of research Russian and American scientists “created” the four radioactive elements – numbered 113, 115, 117 and 118 – by smashing atoms together.
