I got three of your "Kleinsteins" away back in about 2010 (one each for Dad, me, and my best friend). As I recall, there was something very nice in the hand-written note in with the packing slip, but that has got lost in the three subsequent house moves.

Never encountered that in the 1980s. Though I did have a friend who, like you, made a little money on the side typing up people's theses for them. And inserting up to 11 "Judas pages" with deliberate erors [sic] on them, to encourage the recipient to do their proof reading carefully. (He'd say there were a dozen "Judas pages", not 11.)

What you describe would have been fought by the SRC (Student's Representative Council : trade union, in effect) as being biased against poorer students, and in favour of richer students. Which may be acceptable behaviour in America, but in socialist Britain, didn't fly. Marks could be deducted for poor handwriting, sloppy diagrams, etc but this was meant to be a minor part of the marking, unless it was so bad that the work was literally incomprehensible.

It's not as if your work was expected to be returned so quickly that you didn't have time to do a "rough copy", and then a "copy book" copy. Indeed, this was strongly encouraged as a way of developing the habit of writing, then editing and reviewing your work before presentation. In short : professionalism. I gather that is no longer valued significantly. Certainly not on Slashdot.

Actually ... one class lecturer - mathematical statistics - did issue homework on Tuesday afternoons, to be marked "in seminar" on the Wednesday morning. But you were expected to present your work as a "round robin" at the blackboard, passing from one class member to another at the TA's whim. But there, your marks were awarded on your presentation to the seminar, not the beauty of your notes, and the actual red-pen marking was done by your seminar neighbour.

What do you think is the velocity of a particle (say, falling from Sedna's aphelion to the surface of a Sun-size BH) when it crosses the event horizon. And consequently, what is it's time dilation factor?

It might break the speed limit. For tarmac roads. Small-integer fractions of c ? I don't think so.

In your external frame of reference. In the impinging particle's FoR ... less so. After a few microseconds - including time dilation - it reaches whatever is happening at the centre. How much it interacts with whatever is there ... we don't know.

Oh fuck. I just spent an hour flogging through this, trying to get your thought experiment to work, and not really getting there. Then Slashdot's Cloudflare comment-destruction mechanism ate my comment, and I hadn't saved a copy.

Short version : I don't think your idea works, but it was worth an hour of thinking and typing. The details have vanished into Cloudflare's bit-bucket. Sorry. Blame Slashdot.

I should remember to copy-before-submitting. But the blame is still on Slashdot.

When you submit your longhand essay, which didn't involve AI at all, the OCR engine is going to introduce a lot of errors once the TA has scanned it in. That's on top of the errors from the TA not dusting the platen of the scanner down before feeding your pages in.

Use both sides of the paper, double-spaced so you can see the other side of the page from the side you're scanning.

Cut' em some slack.

Only after they've matured to a suitable level of "gaminess". Which, in my area, is determined by the head coming off and the nicely ripe body falling to the floor.

Ableist.

Haven't they replaced the stairs with wheelchair-friendly ramps yet?

At the ESA? I don't have one.

I remember selling my Escort for scrap in 1993 - did you get the rust holes in your floor pan welded up? I didn't figure it was worth the effort.

They forgot to blow the dust off the slide rule, so the batteries were making intermittent contact.

Only for low-importance jobs, like "unpaid intern for translating into American". They're high turnover jobs, so going through the full recruitment process every time an incumbent is throttled by their own intestines (see Adams, 1978 for details) is considered an (Australian-standard) WOMBAT.

The "Olympic Pool" has been deprecated almost since inception, by the repeated error of producing two sizes of "Olympic Pool", differing in dimensions by the thickness of two sets of tiles and grout.

They're using International Standard Texas feet. Everything being bigger in Texas, they decided to have their own version of the "foot" in 1792 CE, and but some of their closet Communist legislators set the "ft(Tx)" to equal 1m. Texas will require America to convert to Texas feet during their 2025 secession campaign, as an alternative to another very un-Civil war.

Oh no, not that one again!

It was a sperm whale. Variety : very confused.
