I‘ve thought about the question which method is better if you want to calculate C=A/B and A,B contain randomly distributed numbers, e.g A around 300 and B around 400. So, method 1 is mean(A)/mean(B) and 2 is mean(A/B).

Propagation of a pulse in a string fixed in both extremes. In partial differential equations, we call this type of end conditions "Dirichlet boundary conditions. Here the reflection happens out-of-phase.

Here, the string can slide on the right. In partial differential equations, we call this type of end conditions "Neumann boundary conditions". Here the reflection happens in-phase.

I’ve been working on Mach 6 shockwave / boundary layer interactions on flat plates recently. It takes less than two hours to go from thought to plot, but honestly, I just think the output adaptive grids look really nice! #SimulationSaturday#CFD
Is #simulationsaturday a thing? Well it should be! We have an awesome simulation center to learn procedures, diagnostic ultrasound, and emergencies! Here you see a mode of a fetus with 3D renderings on the left and the ultrasound image on the right. #radres#futureradres
