Cool! Obligatory https://xkcd.com/195/ Its locality properties provide a practical alternative to the Hilbert curve for this type of map. Also interesting that it is loopy.

I am unaware of any effort in that direction, but I did find a 1987 paper by Höllig [1] that seems to do a kind of converse (approximates FEM solutions using splines. I haven't read the paper, but that's my quick take). Recoverin

Spline interpolation is a rich and extensively studied field, dating back to at least the 1940s. Here are a few comments about related work. The interpolation algorithm itself can be adjusted in numerous ways. One effective algorithm for re

The post lacks performance metrics, so it is impossible to know if their effort was worth it. It would be improved by explaining how performance is assessed and why their method is better than an existing or much simpler (e.g., rules-based)

The Standard Model predicts a vanishingly tiny EDM for the electron — nearly a million times smaller than what current techniques can probe. This is a big achievement, but a lot more work in this direction remains.

Interesting - I also used Jaccard similarity to classify clusters of malicious ad traffic schemes. The idea worked well. It was unclear if the similarity was due to mimicry or authorship, but that did not matter for our use.

"Towards" in a title usually means the authors didn't do what follows in the title. I have no opinion on the article (and no expertise in the field), but whenever I see "towards", my aim in reading the article often

I thought colorblindness tests were designed to be tricky and subtle, so I always passed them through very close inspection. I'm just colorblind.

Not at all! I had the same question. Sorry for any misunderstanding, I edited my comment.

The axiom of choice, Tychonoff's theorem, and the open mapping theorem [0, 1, 2]. Each one took me, in my view, much too long to grasp. [0] https://en.wikipedia.org/wiki/Axiom_of_choice [1] https://en.

Firewood deliveries have been a regular occurrence in past years [0,1]. It seems plausible that these past deliveries established a central place where wood is stored, and it also established a local norm where firewood is distributed. Al

From TFA: “Our wood pile remains inaccessible.” They have wood but they cannot reach it to make deliveries to people in the area. Several decades ago, I recall driving along I90 in SD a few days after a large storm, and we saw drifts as tal

I see the motivation and skill of your group, and I hope you can retain that and build a useful contribution. I also see the extraordinary effort required to get to this point, and many projects fail to get this far, so congratulations. So

Linking to the cited followup study that ran 36 years later. Similar results are reported. https://files.eric.ed.gov/fulltext/ED565462.pdf

Perhaps. However, if there were any evidence of 1-or-2 versus 19-or-21 type thinking, I would expect the results to be non-random. But the results of asking students who should know the answer were equivalent to random guesses.

by jethkl 4y ago
Yes. I interpret the results as evidence of serious and systemic problems.

I agree that this is a trivial question. But the linked pdf explains why it is an interesting question: it was posed to 20k US 8th graders in 1978, and the results were random. The same question was posed to 48 US students in 2014, and resu

In 1978, a US-based study posed this question to 20,000 8th graders. Just 24% selected the correct answer. This is basically equivalent a random guess. In 2014, the same question was posed to 48 suburban US students. Only 27% selected the c
