In 1909, Carathéodory pioneered the Axiomatic Formulation of Thermodynamics along a purely geometrical approach.

Some purely geometrical problems arise out of the study of computational geometric algorithms, and such problems are also considered to be part of computational geometry.

It was simply surface, in the purely geometrical sense.

The design idea of the neighborhood may seem to be purely geometrical, but it has been likened to a chemical structure.

Book on Sphere Packing "I find it really lovely that this purely geometrical thing that I'm interested in is actually useful to quite practical people," Dr. Conway said.
