FB Recap: Major Tom is Everyman, and That’s the Problem
I’ve liked this song since the 1980s but this has bothered me almost as long:>>All systems are go, are you sure?Control is not convincedBut the computer has the evidenceNo need to abort<<The implication is, Control should have aborted the mission based on their gut feeling. But if the computers have the evidence, why is Control not convinced? If Control has other evidence, why isn’t it being considered? If there is no other evidence, then Control wasn’t correct, just lucky.This fits a larger pet peeve of mine, which is that we remain mired (in terms of arts and literature) in an Age of Heroes mentality. It’s the lone actor struggling against the impersonal unfeeling “system”. But in fact, far more tragedies happen because we ignore the evidence than because we follow it. When gut reactions work out, we celebrate it as heroic and when they fail, we say, “Oh, well, sometimes the odds are stacked against you”.We live in the most interconnected complex society ever, during the most dangerous century ever. Systems, professionals, and procedures may all, admittedly, be faulty.But we hold as our paragon the people who work around procedures rather than those who try to fix them. Why? I suspect because it lets us off the hook. If the system is irreparable then we’re justified in not exerting ourselves to repair it. If guts trump process, then we have tacit permission to give free rein to our laziness, our proclivities, and our prejudices. -
FB Recap: Sociology of Exponentials
Explaining the socioeconomic tyranny of exponentials, via examples students can relate to: Let’s say kids are given the whole period to complete a lab. Some students work faster than others because they’ve got a better sense of the underlying theory. So they finish early, meaning they can then move on to work on other stuff. Students struggling with the lab don’t get that opportunity, so their other works looms waiting to be done, increasing their stress and likely reducing their capability. So next time, the students who finished early are more likely to finish early AGAIN, and the students who struggled are probably even further behind.The economy is like that. If you earn more than what you need to survive, you can invest the excess into yourself — maybe a class, maybe just reliable healthcare, maybe things to reduce your stress and enhance your productivity … meaning your earnings will grow even more, even more exceeding the threshold — creating a virtuous cycle.But if you earn too little, you’ll have to make up the difference by working a second job (blowing through your personal health capital), or taking on debt, or some other mechanism that negatively impacts your productivity … meaning you’ll need even more debt (or whatever), a vicious cycle.Sure, in real life, there’s a lot of noise there. Your cost of living fluctuates and so does your earning potential Small chance events can put you over the break-even line, or drag you under it. Life is pretty precarious right on that line. But the effects of small bits of luck (good or bad) become massively amplified by this exponential factor. Yeah, it’s possible that you boost your earnings by hard work alone — but once you clear that break-even line, most of the heavy lifting is going to be done by the network effects that create the exponential feedback loop.I wish I could end this with a simple solution. I don’t have one. But understanding the exponential aspects of life at the break-even leads me to believe, strongly, that we need to flatten out the curve proactively. -
FB Recap: Privilege in Back to the Future
Growing up gives you a perspective that can ruin all the good things of your childhood. I’m going to comment on Back to the Future here, so if that’s an integral pillar of /your/ childhood, you might want to skip.(more…) -
FB Recap: Seal and Eagle
Interesting socio-cultural question: In this cover of “Fly Like an Eagle”, Seals sings “I want to fly like an eagle” but omits “till I’m free”, and changes “through the revolution” to “into the future”.These aren’t accidental changes — I wonder what prompted him and what does it say about the times in which the songs were released (1996 versus 1976). Or… was it because Seal’s version was for a major studio film (Space Jam, believe it or not) and the corporate overlords would brook no mention of the revolution? -
Facebook recaps
As usual, I told myself all Spring Break that I should be writing more. Then I realized that I output a noticeable amount of musings, rants, and thoughts — not a flood, but at least a trickle — on Facebook and other social media. I’m going to go through and pull out the longer or (in my opinion) more noteworthy posts and repost them here on Mongrel Dogs. Because self-plagiarism is by far the best kind of plagiarism.

Math Education and Pandemic
{Editor’s note: Well, this ends up being quite the little snapshot of the early days of the pandemic, for me. I don’t know why I never quite finished it — probably it had something to do with the world igniting — but it’s OK as is, so I’m publishing it. Further years of teaching have only confirmed for me the soundness of the basic thrust.}
The global COVID-19 pandemic has thrown into sharp relief a number of failings of the American system, and one of them is the thrust of math education. It’s been obvious for years that the current paradigm favors abstract symbolic manipulation over practical and intuitive math sense. The explosive propagation of the coronavirus, and the stumbling incoherent response by governmental and business leaders, makes clear that this choice has carried a real human cost.
Put bluntly: It’s time to stop fetishizing the attainment of calculus as the epitome of math education. I taught Precalculus for two years. Looking back, I wish I had hit harder on the chapter on exponential functions. I wish I had done more with real data, more with spreadsheets, more with graphs and interpretations of graphs. I wish I’d spent a couple of months on it, instead of a couple of weeks.
I’d claw the time back by jettisoning, wholesale, the utterly useless chapter on finding polynomial roots. Everything worthwhile in that chapter could be handled in, maybe, four days. I’d probably trim or skip conic sections, too.
Given the chance, I’d lean hard into number sense, too. It’s becoming clear that people are dying because Americans can’t distinguish thousands, millions, and billions. They don’t understand rates-of-change or exponentials. They have no patience for numerical analyses. We make too many judgments using the hard-wired story-telling circuitry of our semi-evolved monkey hindbrain, and we don’t use the vast effective mental technology that’s been invented since 1600.
Americans doubt experts, and why not? We’ve spent decades “educating” them that experts are high priests of a religion beyond their comprehension. When that false god proves fallible, why should they continue to believe? We as educators have failed (miserably) to de-mystify mathematics. We accept the narrative that there are math kids and not-math kids, and we adjust to the confines of that view. Mathematics is both the birthright and the duty of all humankind, and the structures we’ve accepted simply do not recognize that.
My top-of-my-head new Precalculus course would be … well, first, I’d jettison that idea that there should be a precalculus class. A whole year in service of a later course that many won’t even take? Bah. Instead, this is what I’d like to see the mid-level high school math class cover.

Flags of Freedom

A US flag with 35 stars in the field, created after West Virginia was added to the Union. So there’s a controversy with Nike again, because Nike pulled a line of shoes showing the so-called Betsy Ross flag. (You’ve seen it — it’s the one with a circle of 13 stars.) It’s not entirely clear why Nike did so. Some sources says it’s because Colin Kaepernick asked them to (and if so, it’s not clear why he did, although Vox claims it’s because “he argued, is pulled from the era of slavery and doesn’t warrant celebration”). Further investigation seems to indicate that some white nationalist groups have started using the “Betsy Ross flag” as an emblem.
