Today’s XKCD includes an interesting puzzle. Since I should be packing up most of today I’ll leave it to you for now, but I may come back and post my own solution (or as far as I have it) later. To break it down to just math, remember that resistances add along series circuits and inverse resistances add along parallel circuits.
Go!
This is mainly an expository blath, with occasional high-level excursions, humorous observations, rants, and musings. The main-line exposition should be accessible to the “Generally Interested Lay Audience”, as long as you trace the links back towards the basics. Check the sidebar for specific topics (under “Categories”).
I’m in the process of tweaking some aspects of the site to make it easier to refer back to older topics, so try to make the best of it for now.
