During another archeological dig in my home office I cam across a couple of forty-year-old small notebooks. Each one is filled with pages of math, geometry, physics, electrical engineering, and other odd and esoteric formulae.

Below is a random selection of pages from the notebooks. Beware attempting to duplicate these formulae at home, you never know when you may summon and Ancient One!

Note: The images were processed to make the age-yellowed pages more legible.
