Here I chart this rise in terms of the size of computable molecules. By computable I mean specifically how long it takes to predict the geometry of a given molecule using a quantum mechanical procedure.

So indulge me whilst I record this perspective from the viewpoint of the computers I have used over this 62% of the computing era. (more…)
