Credit for the periodic table of the elements generally goes to Dimitri Ivanovich Mendeleev, but a specialist in the history and philosophy of chemistry says the Russian chemist probably peeked at the ...
At the middle of the 19th century, 63 chemical elements were known to science. Before Mendeleev’s discovery, attempts at arranging them in some logical way were made by Johann Doebereiner (1829), ...
The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance ...
DMITRI Mendeleev had a problem. As a professor at the University of St Petersburg in Russia, he was supposed to teach chemistry to students, and to guide him in that task he had arranged a contract ...
This year isn’t only the 50th anniversary of the first moon walk, it’s also the 150th anniversary of probably the greatest breakthrough in the study of chemistry, the invention of the periodic table ...
When Dimitri Mendeleev published the first periodic table 150 years ago, only about half as many elements were known as today. Over the ensuing decades, researchers have added new names to the chart, ...
Russian chemist may have peeked at predecessor's work, but he still should get credit for modern chemistry, says author. Michael Kanellos is editor at large at CNET News.com, where he covers hardware, ...
