As watching actual paint dry is not the most exciting activity for a scientist, we took the safest and the fastest method: computer modeling of chemical processes happening in paint. The method does not damage any paintings, and good models can predict years of paint drying in an hour or two.
Chemical reactions evolve in the same way as water flows through a network of rivers. When describing a chemical reaction you can imagine that the concentrations of the reactants are flowing through the reaction network in the same way as water flows through the network of rivers.
Have you ever thought about a relation between chemistry and networks? Already from school courses we get the feeling that there is some interplay between mathematics and chemistry. In this article we will see how graph theory can help us understand the way chemical reactions occur.
