Question: Does a voltmeter have any internal resistance, and if so, what, if any, affect does it have on voltage readings? Answer: Even if you have no electrical experience at all, I would hope that your answer to the first part of the question was, “yes.” Otherwise this would turn out to be an incredibly short …

Euler’s Formula
Besides being an obvious lady killer, Swiss mathematician Leonhard Euler gifted the world with some pretty important mathematical concepts, notational conventions, and formulas. I almost feel bad about the fact that I couldn’t even spell his name correctly until I was well into adulthood. You are probably thinking, “Sure, he had a bitchin’ robe, and for …

Complex Numbers and their Geometry
(Note: I lied. This will be my first “neural dump.” I began writing about Euler’s Formula, but felt what follows was worthy of its own post and a better foundation for what will follow when I tackle Euler.) Complex numbers arose from the fact that there is no solution for in the equation in , …

Finally Bought an Arduino Yun
I’ve had my eye on the Arduino Yun since it came out, but between an Uno, a Duemilanove, and a handful of shields, I always had something to play with and hadn’t run into any limitations that justified picking one up at the expense of some other shiny, new toy. Last week, however, a perfect storm …

Why “Neural Dump?”
I will soon be making the first post that I believe lives up to this site’s name, “Neural Dump.” The post will be an informal outline of the derivation of Euler’s Formula. I consider this forthcoming post to be a “neural dump” since the audience I am primarily targeting is me. “Huh?” you ask. Well, …
