Building a Solid Foundation for Understanding Seismic Waves

April 22, 2021

In 1906, there was the California earthquake. In 1908, there was the Lawson Report. In 1910, Harry Fielding Reid proposed the elastic rebound theory. Continue on a deep dive into seismology…

A Quiet Revolution: Analyzing Electric Motor Noise via Simulation

March 2, 2021

The sound we hear from electric-powered machines is a multiphysics phenomenon: A motor’s electromagnetic activity sends vibrations through both the machine and the surrounding air.

Happy Birthday, Claude-Louis Navier

February 10, 2021

When you hear the name Navier, you probably think of fluid flow or the Navier–Stokes equations. But did you know that Claude-Louis Navier worked as a bridge designer and civil engineer?

Happy Birthday, Friedrich Paschen
