Beneath every perfect wave is a formula of wind, swell, and seafloor. But for those who chase them, the ideal ride is part science, part soul. Carson’s words reflect something surfers have long ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...

The authors prove global existence of small solutions to a semilinear wave equation outside of convex obstacles. This extends results of Christodoulou and Klainerman who handled the Minkowski space ...

It was shown in two earlier papers that, if u(x, t) = u(x1, x2, x3, t) satisfies the wave equation in the exterior of some fixed sphere r = a and vanishes for t ⩽ r, then ru(rξ, r + τ) ∼ f(ξ, τ) as r ...

Extreme heat can pose several health risks, especially during sustained periods of high temperatures. However, a uniform definition of a heat wave doesn't exist. As a result, public health agencies ...
