Recommended by Ricochet Members Created with Sketch. History and the Vector of Shame

 

Perhaps you have seen the meme that shows WWII soldiers and says something along the lines of “they stormed the beaches for us, we’re just being asked to stay on our couches.” As far as exhortations to stay home go, I suppose it is one of the less annoying and more anodyne ones, but it’s still full of a smug, pompous, and scornful shame directed at us today, extolling the virtues of our honored ancestors over and against the alleged sins of our current generation.

It absolutely reeks of the sort of derision that says “not only are you no better than them, but you’re actually likely a great deal worse since we have to nanny you into staying in your own home.” It is an appeal to heroic nostalgia for a sepia-toned and non-existent past, where somehow the people were “more real,” more manly (or womanly) than today. Putting aside my general annoyance with such nannyism, as a perpetual student of history, I also have to cry foul over the comparison and call it what it is: bilge.

From the invaluable comic Flintlocke’s Guide to Azeroth

Being a man subject to his vices, I’ve started up again on World of Warcraft. Not the new stuff, the “Classic” servers. “Is that what’s taking up your time?” I hear you all saying, “I had wondered why it was slightly less nerdy and pedantic around here.” Well, worry no more! For the joy and edification of the Ricochet audience, here I reproduce the work I did with the damage formulas. Because a simple post about Warcraft wouldn’t be nearly nerdy enough.

It all stemmed from a simple question; which is better, strength or agility? Strength adds damage, but agility adds some damage as well, and some critical hit chance too. So how do you compare them? You can’t categorically say that one is always better than the other. Well, you can, and people often do. But you can’t and still be right. In a broader sense, how do you decide between two items? Here, let’s go shoe shopping. Which pair of boots do you think goes better with my yellow damage?

No, not vector in the epidemiological sense. The other, mathy kind of vector. Which, trust me, are fun. At least stick around for the zombies.

This dates back to my college days, when I took Differential Equations. Twice. I’ve always been good with math. Sure, I struggled with plenty of things along the way (percentages, trig identities, multivariable integration. Oooh, and concentrations in chemistry), but DiffEq is where I hit the wall like a coyote hits his own painted-on tunnel. Vector spaces were part of that; an abtruse concept used to justify an abstract concept used to solve some difficult equations that might, in turn, have something to do with the real world. But once I got my head wrapped around them, vector spaces turned out to be a fun and useful bit of math. Hey, it could happen.
