Printing and the Mind of Man is a book first published in 1967 [1] and based on an exhibition in 1963. [ 2 ] PMM , as it is usually abbreviated, is regarded as a standard bibliographical reference, and offers a survey of the impact of printed books on the development of Western civilization .
According to the final chronology of the first publications of the Mendeleev’s Periodic Table (Druzhinin, 2020 [1]), the first Medneleev ‘s Table published March 26-27 [O.S. March 14-15] 1869 in the Mendeleev’s The Principles of Chemistry 1st Edition, and around March 17 [O.S. March 29] 1869 Mendeleev printed separate broadsheets with ...
Mendeleev's office and library in his apartment in St. Petersburg. Dmitry Mendeleev's Memorial Museum Apartment is a museum apartment of the Russian chemist Dmitry Mendeleev, who is famous for establishing the Periodic table of arranging chemical elements by their atomic masses, which allowed the prediction of properties of elements (i.e., simple substances) yet to be discovered.
To give provisional names to his predicted elements, Dmitri Mendeleev used the prefixes eka- / ˈ iː k ə-/, [note 1] dvi- or dwi-, and tri-, from the Sanskrit names of digits 1, 2, and 3, [3] depending upon whether the predicted element was one, two, or three places down from the known element of the same group in his table.

Dmitri Mendeleev invents the periodic table, bringing order to the understanding of the elements for the first time; Marie Curie discovers several elements, including polonium and radium, and discovers radioactivity, demonstrating that elements can change identities and may consist of previously unsuspected subcomponents.
