If you’ve ever dealt with orbital mechanics or sophisticated computer graphics, you’ve probably run across the math term quaternions. [Anyleaf] has a guide to the practical use of this math concept ...

Plotting three Euler angles using an RGB color scheme is the best way of generating an orientation map, which is normally referred to as a Euler map (Figure 1). Figure 1. Euler angle coloring ...

We study stationary homogeneous solutions to the 3D Euler equation. The problem is motivated by recent exclusions of self-similar blowup for Euler and its relation to the Onsager conjecture and ...
