“1. The elements, if arranged according to their atomic weights, exhibit an evident periodicity of properties.2. Elements which are similar as regards their chemical properties have atomic weights w...”

“In science we must all submit not to what seems to us attractive from one point of view or another, but to what represents an agreement between theory and experiment.”

“To burn oil!.. You can fuel with money as well.”

“I wish to establish some sort of system not guided by chance but by some sort of definite and exact principle.”

“The occultist has the satisfaction of knowing that the great Russian chemist, Mendeleef, preferred the atomic theory. In Sir William Tilden's recent book entitled Chemical Discovery and Invention i...”

“Even though Mendeleev always denied that electrons exist, they later turned out to be vital for ordering the elements in his table.”

“His stroke of genius was to leave gaps for elements that were still to be discovered, predicting what their properties should be from his table. This was a tremendous publicity coup! A few years la...”

“When Mendeleev began teaching at the University, there were 63 known elements, each identified by atomic weights newly determined by Avogadro's hypothesis. He had to develop some system of classifi...”

“Mendeleev was not concerned in 1869 with establishing a basic law of chemistry. He was concerned with writing a textbook for young chemists at St. Petersburg University. ...From 1871 on, Mendeleev ...”
