Chemical processes are translated into mathematical functions by physical chemists, who use the laws of physics to describe and analyse the chemical reactions in the lab and in the wider universe. The way that various changes impact the composition of chemical substances has been extensively analysed using mathematical models which are constantly being improved upon. The theoretical work of physical chemists has made recent advances in analytical chemistry possible, allowing chemists to delve deeper into the structure of molecules to find out what’s really going on on a never-seen-before level. Even more exotic and yet essential to the core of chemistry is the application of sophisticated quantum chemical models, in which particles are described by wavefunctions and are no longer governed by the laws of classical physics.

Thermodynamics is very successful at describing the way energy interacts with itself and matter - but every now and then a paradox will pop up, or someone will spot an event which no one has an explanation for yet.
