Can we see a single photon? Short answer is “no.” While the biology of the typical human eye is sensitive enough to detect a single photon, the human visual system also cannot distinguish such single photon excitement from background noise. So these low energy excitements are filtered out and we cognitively cannot “see” a single photon.

Singapore is pretty "innovative" in what they do. Would not surprise me if they were able to make this succeed.

Has a very nice animation showing how exp(ix) encapsulates both sin(x) and cos(x).

That was rather cringe-worthy.
Complex numbers aren't more or less "real" than other kinds of numbers. This is just BS. All kinds of numbers are defined by axioms, and if they are not contradictory the axioms have a "model". I could invent seven new kinds of numbers today and they wouldn't be more or less real than rational numbers or real numbers.

On the scale of Aqua numbers between shitpants and fibbeldyfuck, how would you rate the educational quality of the video overall?

I find it sensationalist.
Numbers are constructed, just like buildings or cars, except that the parts are replaced by axioms.
For instance, here's a definition of what an N-Number is:
- Z is an N-Number.
- For every N-Number x, S(x) is an N-Number.
If we write Z as 0, S(Z) as 1, S(S(Z)) as 2 etc., then you see that I've just defined something like the natural numbers.
It works the same way for all other kinds of numbers. It's not all that interesting, really. It is interesting when the definitions are useful, i.e., if you can use them to model real-world stuff with it. It turns out that complex numbers are useful in that sense. But they are not qualitatively different from any other kind of number.

I read something similar that the airline associations with credit card companies make the airlines as much or more money than ticket sales.

Hong Kong “kungfu cop” movie, probably from the 1980s.

Fighting sequences are very well done. The whole movie is quite fun to watch. Feels like the missing link between Bruce Lee and Jackie Chan. Sammo Hung delivered the sort of fungting style later popularized by Jackie Chan (minus the “comedy” from Kackie Chan’s ”action-comedy“), but at the time Sammo Hung still immitated Bruce Lee‘s high-pithced vocalizations. -

The dialogue is actually in English, despite the cover graphics.
It's a video on job performance review.
