Chemistry is the third 
Science Research available at the Library. It is preceded by Mathematics and is required to research the fourth Science technology, Laws of Nature.
Researching Chemistry gives a further discount to Library research and further increases the LOS of scouts, cities and Lookouts/Observation Posts/Air Defense Guns/Radar Air Defenses/SAM Installations. It also unlocks the Smelter, the Agriculture and Medicine technologies for the Granary, the Carpentry and Architecture technologies for the Lumber Mill, and the Literacy technology for the University.
