For pretty much my entire life, i’ve never managed to develop the ability to memorize anything useful, yet my brain soaks up the most trivial and esoteric mundanities with all the energetic thirst of a Death Valley sponge factory.
For example, did you know that Billy Preston played keyboards on the Beatles “Let It Be”? I heard that fact once, sometime back in the 1970s. I have no use for it, yet it stays with me.
For most of my academic career, i had cause to use the quadratic equation. All i can tell you, then or now, is that it has a square root in it. Or maybe it’s a cubed root. Crap.
