What is μV?
I often get asked what the title of the blog means, so I figured I should explain. μV is the SI symbol for the microvolt, the unit of measurement for evoked potentials (and other electrical impulses of varying nature.) Evoked potentials, simply put, are the measurable electrical responses of the brain to a repetitive external stimulus. The subtitle of the blog was originally "Everything is waves." The idea was that anything and everything that exists and occurs is quantifiable and qualifiable in wave form. In my view, waves are the more organic and universal way to represent existence and to comunicate. After all, they are natural, observed phenomena, shapes and patterns, as compared to numerical and mathematical representation/expression, which are also a way of describing and quantifying anything but are, nonetheless, human constructs, artifices. Ultimately, I found having a subtitle on a dumb tumblog to register at a whopping 7.5 on the Pretentious scale.
I broadcast these stimuli to you and (hopefully) they evoke some potentials that will be interpreted by the rest of your being, which will in turn produce a reaction that will be read as waves by something else and so on and so forth.
