Text 2 A
The World’s Greatest Chemist
The periodic system of the chcmical elements by Mendeleyev has long sincc served as the greatest history-making contribution to the study of nature. As any work of genius it shows two characteristic features: it adds more to the present knowledge, and it fruitfully develops along different directions in future.
It allowed to predict in advance the existence and properties of yet undiscovered elements. Many outstanding researchers owe to it, to a considerable degree, the ideas of their experiments, calculations, hypotheses and theories. Take, for example, the German Otto Hahn, who discovered the fission of the uranium nucleus. Or the American Glenn Scaborg who led a group of researchers that obtained, in laboratory conditions, a number of elements, including mcndclcvium, named in honour of Mendeleyev. That element bears the name of the great Russian scientist not only bccausc Mendeleyev laid the foundation of the modem science of atom, but also bccausc he drew his colleagues’ special attention to uranium (No. 92), which at the time had closed his periodic table. A long train of transuraniums followed the once “final” uranium.
“The Mendeleyev system has served for almost 100 years as a key to discovering new elements,’’ Scaborg wrote in 1955. It has retained its key capacity until now.

To commcmoratc Mendeleyev himself, the Soviet researchers named many newly discovered things on the earth or in the outer space after him: a crater on the “back” side of the Moon, an underwater ridge in the Arctic Ocean and the mineral mcndclcycviic. Villages, streets and establishments such as the Moscow Institute of Chemical Technology, the Tobolsk Pedagogical Institute, the All-Russian Institute of Meteorology, the Museum of the St. Petersburg University building (where the scientist lived), the All-Russian Chcmical Socicty, etc. have got Mendeleyev’s name.
Mendeleyev, the explorer of nature, has found real immortality in his pasting heritage. The periodic system hasn’t crumbled with time; on the contrary, its structure has expanded. At present it is the basis of modem teaching on substanccs, the structure of matter, atoms and nuclear energy.
“The greatest chemist of the world” — this is Mendeleyev’s fame among modem chcmists. Yes, he, the founder of modem chemistry and, to a large degree, of modem physics, considered physical chcmistry his main subjcct, while he successfully dealt with problems in different areas, from mathematics and astronomy to meteorology, from philosophy to economics, from technology to art. “He has penetrated everywhere,” the great Russian poet Alexander Blok once said.
Mendeleyev’s notes on “three services to the Motherland” arc quite interesting. He places work as an explorer of nature at the first placc. He devoted himself to it. He tried to make his experimental and theore­ tical results serve socicty. He also devoted much of his effort to teaching, to the spread of knowledge. Finally, the third important task in Mendeleyev’s life was to do his best for the economic and industrial progress of Russia.
Mendeleyev’s dreams have come true. As long as seventy years ago the British magazine Nature (of February 24,1934) wrote that in Russia scientists like Mendeleyev are valued and their works help to intensify the development of science, technology and industry.
