His work has had signiflcant impact in the worlds of chemistry, physics, com-puter programming and medical research. Buckminster Fuller’s iconic geodesic dome design was in°uenced by Coxeter, and M.C. Escher re-lied heavily on Coxeter’s theories for his famous Circle Limit drawings.
WebA great example of unexpected simplicity is Coxeter’s integral, which was (of course) solved by Hardy. The integrand is too complex to write here, but the integral evaluates to 5π / 24. One of my favorites is the sinc integral, int 0 to ∞ sin (x)/x dx = π/2. But moreover, int 0 to ∞ (sin (x)/x) dx = π/2 also, with the integrand squared.
