Person doing simulations in plasma physics / astro physics here. I google tons of stuff every day. And I have a hard copy of https://www.nrl.navy.mil/ppd/content/nrl-plasma-formulary https://www.nrl.navy.mil/ppd/content/nrl-plasma-formulary on my desk. And the PDF on just about any of my devices. Once every few years I ask the Navy for 20 copies and hand them out to grad students and colleagues.
