The Genius of Mendeleev's Periodic Table - Lou Serico

The single greatest discovery in chemistry is that of the periodic law.

Before the discovery of the periodic lab (and subsequent creation of the periodic table), chemistry was a collection of random, unorganized facts about the stuff around us.

Sure, there were some elements that reacted sort of similarly, but a few connections doesn't make a system of knowledge.

Then, along came Dmitri Mendellev and his dream.
