Did Archimedes Write a Problem That Took 2,200 Years to Solve?

A poem from the 3rd century BC, attributed to Archimedes, about counting the number of cattle in a Sicilian herd wasn’t fully solved until the 20th century. *Errata* At 03:13, there is a typo in the second equation from the top (the black cows). It should say 9,717/10 + 143/2800*{sigma}, not 9,717/10 + 143/1,260*{sigma}. The subsequent steps are correct. ** Time Stamps: 00:00 - Intro 00:51 - Part I: The Bulls 02:36 - Part II: The Cows 04:31 - Part III: The White and the Black Bulls 05:38 - Part IV: The Yellow and the Dappled Bulls 07:33 - History of Pell Equations 09:12 - Path to a Solution 10:36 - Archimedes ________ Some useful resources about the Cattle Problem of Archimedes: Archimedes related web site maintained by Chris Rorres: https://math.nyu.edu/Archimedes/Cattl... @numberphile video on the Cattle Problem:    • The Archimedes Number - Numberphile   Video by @OliverThomas1 explaining methods to solve the problem:    • Counting Cows: the ancient Greek 'Cat...   “Archimedes’ Cattle Problem” - Ilan Vardi - https://math.nyu.edu/Archimedes/Cattl... “A Simple Solution to Archimedes’ Cattle Problem” - Antti Nygren - https://math.nyu.edu/Archimedes/Cattl...

However, when mixed with real historical imagery, it has the potential to create confusion, or worse, if not handled properly. Additionally, there is important discourse about issues of ethics, intellectual property, etc surrounding AI imagery. I have used Midjourney AI to create “stock” image elements including backgrounds, illustrations, and objects. I do this because it allows much greater specificity than is possible with stock image services (you need a white cow and bull, a yellow cow and bull, a spotted cow and bull, and a black cow and bull, and you want them to be in an "old" painted style? You got it!). Additionally, in this video I used AI generated images of what we popularly imagine Archimedes to look like. Not only are there (obviously) no photographs of Archimedes, there are no surviving images of Archimedes whatsoever. Most of the modern imagery of him is based on a statue, located in the Naples, Italy Archeological Museum. The problem is that scholars eventually figured out that this was actually a statue of ArchiDAMUS, a 4th century king of Sparta, not ArchiMEDES.... All of this being the case, I see no risk of misinforming or creating historically inaccurate images in generating his likeness using AI (after all, it is just as "inaccurate" as any other drawing or painting that exists).
