Mathematician, programmer. Co-developer of the Jep mathematical parsing library.
My picture is of the A3 singularity defined by
x^4 - y^2 - z^2=0 and rendered by my singsurf program This is quite a tricky surface ot make a polygon mesh from as it contains a singular point. I've spent more time than I care to calculate making sure the program can create meshes for many singular surfaces.
I also do private mathematics tuition of all levels upto degree level.
