Partial differential equations (PDEs) lie at the heart of many different fields of Mathematics and Physics: Complex Analysis, Minimal Surfaces, Kähler and Einstein Geometry, Geometric Flows, ...
A new equation for accurate approximation of the Moody friction factor in the general gas-flow equation better approximates a wide range of Reynolds numbers than previously published equations. Other, ...
SINCE Newton and Leibniz began to study differential equations in the seventeenth century, mathematics has made great strides. Though the creative mathematicians have mainly been inspired by the art ...
