I am using Staedtler Mars Lumograph 3B (#1) to write notes on book margins, but I still find it not dark enough. I plan to buy a darker one in future, but the article says that the darkest ones are all prone to smudging. So, I'll proba

The compass button slightly confuses me. I thought the arrow in anticlockwise direction was intended to turn the map anticlockwise, but it actually works like a GPS navigator, i.e., it works as if I turn my car to the left and the direction

The Nazi salute is called the “Bellamy salute” ( https://en.wikipedia.org/wiki/Bellamy_salute ), which actually was an American invention.

The concept is interesting, but the watch looks ugly and the dial is too small to be useful.

I think this is not a biology-only phenomenon. I have the impression that chemistry and mathematics are also not taught well in many (if not most) high schools. Physics education in contrast seems to be in better shape.

Yes, it's a fun piece of art. I don't think this was meant to be practical. It was probably just an interesting experiment or proof of concept.

I think in the Soviet bloc, "higher mathematics" referred to mathematics taught at higher institutions (i.e. universities or technical institutions at the same level). This usage is a bit different from that in the Commonwealth of

Is the existence of basis in every vector space really useful? I think in analysis, people mostly work with Schauder basis rather than Hamel basis. I am not aware of any important result that uses the existence of Hamel basis in an infinite

I don't think the introductory paragraph of the Gibbs Phenomenon article is bad. Quite the contrary, I think it's well-written. The opening sentence in the Taylor series article is terrible, though, but it's at least factuall

The article hasn't mentioned the sizes of the cubes, but the linked journal paper shows that the typical size is 2.3cm x 2.5cm x 4cm, which is about (but slightly thicker than) the size of a rubber/eraser. So, the shape is more li

If you define determinant as volume, how do you define volume? I agree that it's pedagogically sound to motivate the notion of determinant by the volume of a parallelepiped, but using volume as the definition of determinant just do

You are right. I did learn this term in high school decades ago but have forgotten it. Thanks for the explanation.

Of all time travel stories I know, the one with the most consistent and logical view on time travel isn't Steins;Gate, but Murai Nikki (Future Diary). IMHO, Steins;Gate hasn't clarified what time travel really represents. When one

The article's title is VERY misleading. After the fifth covid-19 case was confirmed in Taiwan (around Jan 25), the Taiwanese government had already banned all mainland Chinese tourists from entering the country. In February, even non-c
