Apparently I am Old Because I've Used Incandescent Light Bulbs
I'm watching a lecture series on electronic theory and the instructor is talking about modeling an incandescent light bulb. He said something like "We're going to talk about a kind of light bulb that's no longer in production. You might not have seen one if you're really young. It has a *filament* inside it, not LEDs." It kind of broke my brain for a few moments.
Also, if you're looking for this sort of thing, these lectures seem really good so far. Between the basic circuits series and the electronics 1 and 2 series, there's at least 100 hours of content here. The lecturer is Behzad Razavi, an electrical engineer with a Ph.D from Stanford, so he probably knows what he's talking about! It's relatively new on YouTube, too, which explains why I didn't find it last time I looked for things like this.
The second lecture threw in a little calculus in talking about how to determine current over time and frankly I was kind of terrified. I haven't gotten to calc yet, and though I was really enjoying teaching myself math through Khan Academy on my own before the Netherlands, the last time I tried I was having a really rough time getting things to stay in my brain and I got really discouraged. When he mentioned integrals, I actually stopped watching and leaned against Miriam on the couch and cried for a little while thinking that my current mental state was going to keep me from being able to learn yet another thing. But the calculus was only a passing reference, and so far at least (and I've only gotten through the first three basic circuits lectures, so maybe that will change) not knowing that level of math is not a hindrance. And Miriam has offered to help me get the gist of the math, too, if there's much beyond my level because she is a wonderful, and pretty smart, partner!
