Building a Solid Foundation for Understanding Seismic Waves
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
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
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
Friedrich Paschen dedicated his life to experimentation. Today, we use Paschen’s law to understand how electric current flows through gas.
