A simple MATLAB DG code for 1D Euler Equation, including the TVB Limiter and pp Limiter. Three types of fluxes are tested: L-F, HLL and HLLC. The test example is the "test 3" on Toro's ”Riemann Solver ...
“Gentlemen, that is surely true, it is absolutely paradoxical; we cannot understand it, and we don’t know what it means. But we have proved it, and therefore we know it must be the truth.” —Benjamin ...
What is it that makes Euler's identity, e]iPi + 1 = 0, so special? In Euler's Pioneering Equation Robin Wilson shows how this simple, elegant, and profound formula links together perhaps the five most ...
Abstract: Many natural and engineering phenomena can be attributed to the ordinary differential equation problems, and Euler methods are the most commonly used for solving ordinary differential ...

Leonhard Euler’s polyhedron formula describes the structure of many objects—from soccer balls and gemstones to Buckminster Fuller’s buildings and giant all-carbon molecules. Yet Euler’s theorem is so ...
WHILE Paul Nahin is not the first to proclaim the power and beauty of mathematics, few have alluded to the “erotic connection between mathematical insight and sexual orgasm”. A stretch too far, ...
