But we have proved it, and therefore we know it must be the truth.” —Benjamin Pierce, a Harvard mathematician, after proving Euler’s equation, e ip = –1, in a 19th-century lecture.

The partial differential differential equations being solved are the Euler equations of gasdynamics: with piecewise constant initial conditions (also known as Sod's shock tube problem ). The ...
