Relativator (Circular Slide-Rule): Simulated with Desmos - Insight

[Greg Bernhardt]

TL;DR

This is an update of my 2006 post (reconstructed in 2014) Relativator: The circular slide-rule for physicists.

This is a circular slide-rule for doing relativistic calculations for elementary particle physics that I learned about from
– an article by Elizabeth Wade ( “Artifact: Relativator”, Symmetry (FNAL/SLAC), 01/01/06

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles.

The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...

What a cool gizmo!!

EDIT: I mean I thought a slide rule was smart, and I was of course aware that there we're specialized versions, but this one takes the biscuit! Unfortunately it's too advanced for me. Still, I'm flabbergasted! (For the record, the likes was from before this EDIT.)
