Last week, I went down a huge rabbit hole and tried to come up with a mathematical generalization of dealing with errors in circuits.

I am not a mathematician, but I tried to come up with a proof as rigorous as possible. However, other eyes are very much appreciated. I'd be happy about a boost and/or feedback.

And of course, I'd be glad if this was useful to anyone else :)

Demystifying Electrical Component Tolerances

Did you ever wonder how the tolerances of resistors influence a voltage divider? What happens if you put two components in parallel — does the effective tolerance increase or decrease? I had some very wrong assumptions about the answers to these two questions and am glad I looked deeper in to the topic. Some very suprising, yet satisfying and reassuring insights into error boundaries and propagation lie ahead. So buckle up and get ready for some math! (I enabled LaTeX \LaTeX LATE​X on my blog for this, hihi)

🚀 Ah, the genius of tackling Knuth’s "Claude Cycles" — nothing like disabling #JavaScript to reveal the true brilliance of AI-human #collaboration 🧠. Just remember, if you can’t browse the Help Center without a hitch, solving complex mathematical problems might be a tad ambitious. 📉

Three weeks ago I shared that Claude had shocked Prof. Donald Knuth by finding an odd-m construction for his open Hamiltonian decomposition problem in about an hour of guided exploration. Prof. Knuth titled the paper Claude’s Cycles. The story didn't end there. The updated

🚀🎉 Wow, a glorified calculator solves a math problem! 🎓🤖 Meanwhile, the #AI #hype train continues to shovel coal into the furnace of self-importance, as if writing about "hypergraphs" is a frontier instead of just plain obtuse. 📈🔍

A Ramsey-style Problem on Hypergraphs

Construct hypergraphs as large as possible that do not have a certain easy-to-check, difficult-to-find property.

Why doesn't #Mathematica simplify sinh(arccosh(x))? Because apparently, it takes a PhD in #Trigonometry, a magnifying glass, and a deep existential crisis to venture into that rabbit hole. 🤔🔍 Just when you thought it was all about cosines and sines, hyperbolics crash the party and demand their own dissertation. 📚🎉

Why Mathematica does not simplify Sinh[ArcCosh[x]]

When Mathematica seems to not to know how to simplify an expression, it may be doing the right thing, being more sophisticated than you expect.
