Small-Scale Question Sunday for January 18, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Jump in the discussion.

No email address required.

Does anyone have their own equivalent of a personal "antimeme", a concept you familiarize yourself with (potentially with difficulty) and then inevitably forget unless you make an intentional effort to look it up?

In no particular order:

  • I often have to look up whether I need an x86 or x64 executable when I need to download a program
  • ECGs. Fucking ECGs. I get good at understanding them when I absolutely have to (before exams), but guess what, by the time the next one rolls around, it's all out of my head.
  • Fourier transforms (how they actually work, and not the conceptual strokes)
  • And many more, all of which stubbornly refuse to come to mind, because of course they do.

I am in this comment and I do not like it.

Et tu, Brute? I keep imagining there's some mysterious phase change where repetition makes it stick.

I had a very awkward referral once, for a patient with a TCA overdose. I looked at it, knew what it was, but when the person taking the referral asked me to describe it, I was "uh... Those T waves look tented?"

Once you get something down you realize you have some new bizarre shit to memorize. It is endless.
