“Math is not about memorizing formulas without meaning, but rather about learning how to reason logically through precise statements,” Dr. Loh said.
(Kenneth Chang and Jonathan Corum, “This Professor’s ‘Amazing’ Trick Makes Quadratic Equations Easier,” NYTimes, 2-5-20)
Dr. Loh’s statement teases me, a non-adept at mathematics, in imprecise ways.
The saucy segments are: “formulas without meaning”; “reason logically”; and “through.”
There are no formulas “without meaning”; a formula “means” what it formulates. It abstracts and generalizes in a repeatable way, and it’s useful only to those who have it beyond memory. It’s the act of lazy head-stuffing that’s meant to be belittled.
To reason “logically” is the same as to drink “liquidly.” How else to do either?
“Through” is tricky. At first I read it as prepositioning the notion of advancement by means of penetrative navigation. Picture, if you will, a thicket of precise statements; then picture yourself reasoning your way “through” them. On second reading, however, I estimate Dr. Loh to imply instrumentality — “by means of.” Picture yourself engaged in a reasoning process, and doing so by making a series of precise statements — reasoning “through” them.
Much stuff is about the likes of “through,” which is why computers are better at arithmetic than at translating.

Artie Shaw on Glenn Miller
I transcribed this snippet from the Ken Burns documentary about jazz. It inspires me to make mistakes at what I’m doing.
[Glenn Miller]… was sort of the Lawrence Welk of jazz. It was one of the reasons he was so big; people could identify with what he did, they perceived what he was doing. But the biggest problem: His band never made a mistake, and it’s one of the things wrong. If you never make a mistake, you aren’t trying, you’re not playing at the edge of your ability. You’re playing safely, within limits, and you know what you can do, and it sounds after a while extremely boring.
