I’m not sure it’s just on Reddit…

Honestly what the homework is probably looking for is that it’s equivalent to “B or not A.” But yeah.

It’s also used for sending huge amounts of data long distances. “Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.” That’s usually attributed to Andrew S. Tanenbaum, but wikipedia follows that with “other alleged speakers include…” so take that with a grain of salt. They do note that the first problem in his book on computer networks asks students to calculate the throughput of a Saint Bernard carrying floppy disks.

Yeah, you’re right. This is something I was taught at one point, and I guess I never questioned it because it sounded plausible. Sorry! I have updated my comment to reflect this.

It’s also because the bacterium in question is anaerobic, so it dies in an oxygen environment; rusting consumes oxygen, so it helps preserve the bacterium longer out of soil.

Edit: I had always been told this, but evidently it isn’t true. The rust does not seem to have any effect on the bacterium that causes tetanus. Apologies for spreading misinformation.

3blue1brown is a great call.

I would add Applied Science and NileRed (who does chemistry experiments) as possibilities if OP likes their voices. Their content is very methodical and uniform. My cat likes their videos, which seems like a pretty good metric for this use case.

I also love vihart, who does math videos, but her stuff is a little more varied, including some music, so OP might want to evaluate her during the day before trusting her channel for sleep.

Jeremy Fielding has a great voice if you want videos about engineering and how to salvage motors out of washing machines and treadmills.

I’ll consult my subscription list and add more if I find any.

Edited to add:
Carl Bugeja (electronics)
CGP Grey (mostly history)
DIY Perks (various projects)
Henry Segerman (math art)
OskarPuzzle (designs for 3d printed puzzles)
Razbuten (video games)
Sabine Hossenfelder (physics)
Stand-up Maths (math)
Steve Mould (explanations of unusual everyday things, I guess? kinda hard to summarize)
Technology Connections (as others have mentioned)
Tim Hunkin (makes weird mechanical art and explains machines)
Tom Scott (videos about unusual places and bits of history)
Two Minute Papers (advances in AI and computer graphics)

Edited again to add: Breaking Taps. This one is mostly microscopic fabrication stuff, so, various kinds of microscopes, vapor deposition, etching, etc.

Fakespot used to reveal more about how they detected fakes, but as you say there are obvious issues with that, as it’s a bit of an arms race. They don’t just look at the text of the individual review though. Folks who buy reviews tend to get them from “review farms” that do reviews for a lot of products, and they don’t have an infinite number of Amazon accounts to use for that, so there are network effects that can be powerful indicators, and that aren’t easy for manipulate.

I don’t think we should be too surprised by this. If a company isn’t all that good before a conglomerate buys it, then it’s unlikely to be widely known. Conversely, if a small company is widely known, it’s likely to be exceptionally good. So, even if acquisition usually just results in regression to the mean, we’ll still mostly have heard of ones that degraded the company.

Good sci fi usually isn’t about the future, aliens, etc. It’s about the present, but portrayed in a strange way so as to bypass your existing preconceptions about the situation, so you can look at it with fresh eyes.
