All Thoughts Being Equal

This post is a follow-up to Diagnosis of an overwhelming fear, pt. 2 , and a partial-follow up to Rhetorical imperialism I. The new hotness in this micro-epoch of the Age of Outrage is at Vox, where a pseudonymous professor touts his liberality but claims that his liberal students are terrifying . "I'm a liberal college professor," cries the headline, "and my liberal students terrify me": I'm a professor at a midsize state school. I have been teaching college classes for nine years now. I have won (minor) teaching awards, studied pedagogy extensively, and almost always score highly on my student evaluations. I am not a world-class teacher by any means, but I am conscientious; I attempt to put teaching ahead of research, and I take a healthy emotional stake in the well-being and growth of my students. Things have changed since I started teaching. The vibe is different. I wish there were a less blunt way to put this, but my students sometimes s...

This was provoked by Scott Alexander's wonderful story "... And I Show You How Deep the Rabbit Hole Goes." I decided to take the original Tumblr meme and put a pessimistic, Needful Things-esque spin on it. Comments and critiques are welcome: I wrote this all at once in a mad haste of inspiration (thus my earlier word choice) so it may or may not be rough. "Let's just say you don't pay... with money. " — Mr. Needful *** YELLOW "Gives you the ability to read and search the minds of anyone you can see, even if it's a picture. You can also turn their minds 'off' to put them into a coma." Yes, now everyone's mind is an open book to you. But alas, the man never said whether you'd be able to understand these books. The first time you attempt to use this power, on a photograph of the President, it felt like that time you had to read Immanuel Kant in college, except that now "A Critique of Pure Reason" was co...

Fact: Ancient Carthage was 300x more metal than the modern day Here's a quick thought on the eve of the new year. In mathematics it's common to take a space or a structure and examine an interesting subspace or substructure of it. For example, when thinking about the integers {..., -2, -1, 0, 1, 2, ...} we can consider the odds, the evens, multiples of 7, and so on. Things get interesting when we can, for example, note that any two multiples of 7 add together to get another multiple of 7, and we didn't have to make up new rules about addition to achieve this. So the "multiples of seven" are a subspace of the integers. So far so elementary. But now consider a bit of geometry. Imagine a two-dimensional rectangle sitting inside three-dimensional space—like a floating rigid sheet of paper. We could draw a circle on that sheet of paper and fill it in. Call the filled-in space A (because mathematicians like naming stuff). Now we might want to know something...
