I saw a talk by Maarten de Hoop, who is one of the seismologists interviewed in this article. The talk centered around designing the structure of __huge__ matrices to help solve immense systems of equations that were constantly being mutated with more input data. Most of it went over my head, as it was a talk also given to the mathematics department, but I was astonished at the ingenuity of the computational seismology community. They were designing and manipulating matrices into complex fractal forms that made these unbelievably complex reduction operations fairly simple and mathematically favorable.
