In 2020 and again in 2024, my cousin Ed Friedman suffered massive brain farts and asked me to contribute cartoons to his otherwise credible scientific endeavors. Click either link below or scroll down for that year's submission:

AKA, CARTOONS AND CORONA VIRUS -- Not expecting them to go viral
These 25 cartoons were created mostly during the Covid-19 pandemic for the 3rd edition of Photonics Rules of Thumb, an otherwise respected reference work for which Ed was a chief editor. About half of them were used in the final version, where space per

From the back cover of the 3rd edition:
Updated and expanded, the third edition of Photonics Rules of Thumb represents an evolving, idiosyncratic, and eclectic toolbox intended to allow any engineer, scientist, manager, marketeer, or technician (regardless of specialty) to make rapid and accurate guesses at solutions in a wide range of topics during system design, modeling, or fabrication. This book will help any electro-optics team to make quick assessments, generally requiring no more than a calculator, so that they can quickly find the right solution for a design problem.
This book has been assembled to introduce anyone working in the optics and photonics community to a wide range of critical topics through simple calculations, graphics, equations, and explanations. Useful design principles and rules, simple-to-implement calculations, and numerous graphs and tables of important basic information allow you to rapidly pinpoint trouble spots, ask the right questions at meetings, and are perfect for quick checks of last-minute specifications or performance feature additions. Offering a convenient arrangement according to specialty, this unique reference spans the spectrum of photonics. Eighteen chapters cover optics, atmospherics, radiometry, focal plane arrays, degraded visual environments, economics, and photogrammetry, as well as technologies related to security and surveillance systems, infrared, lasers, electro-optics, phenomenologies, self-driving vehicles, and many others.

aka "Thanks, Ed!"
While contemplating the 3rd edition of his co-edited collection, my cousin Ed Friedman, normally well respected for his scientific knowledge and logical mind, must have had a momentary lapse of reason, as evidenced by his asking me to submit cartoons for the updated publication. Apparently, he has never fully recovered, as despite being given numerous opportunities to retract his offer, he persisted headlong down this primrose path of digital dalliance. Then, in 2024, he asked me for additional cartoons to accompany his university-level course on quantum mechanics.
These cartoons were created for Ed's survey course on quantum mechanics that he delivers in person at Denver University and via Zoom through OLLI for Colorado State University, as well as for his accompanying textbook. Some target specific concepts or teaching points, while others are more general.
