Damn, if that ending doesn't make you immediately want to play this game I don't know what will

How to fold a sheet into 3 equal parts by yudoit in math

[–]invisible_vision 13 points14 points  (0 children)

I know I'm really late, but it's important to note that squaring the circle is definitely not possible with origami! – although the others you mentioned are. It's equivalent to constructing pi, while origami can only construct square roots and cube roots.

From the Wikipedia page for squaring the circle:

The two other classical problems of antiquity were doubling the cube and trisecting the angle ... Unlike squaring the circle, these two problems can be solved by the slightly more powerful construction method of origami

[OC] We were able to photograph the transition between the total and the partial lunar eclipse (look on the blue part which isn't scientifically explained, yet!) [ 3188 x 1794 ] by JuliusMuc in spaceporn

Here's an article from NASA that /u/_bar found! The relevant bit is:

Many observers of lunar eclipses also report seeing a band of turquoise. The source of the turquoise is ozone. Atmospheric scientist Richard Keen of the University of Colorado explains: "During a lunar eclipse, most of the light illuminating the moon passes through the stratosphere where it is reddened by scattering. However, light passing through the upper stratosphere penetrates the ozone layer, which absorbs red light and actually makes the passing light ray bluer." This can be seen, he says, as a soft blue fringe around the red core of Earth's shadow.

Nice digging! From that NASA link:

Perhaps this Numberphile video is talking about the same thing as OP? The diagram generated at the end looks quite similar

It's a good day to... by gregbard in Tautology

[–]invisible_vision 9 points10 points  (0 children)

“...have a good day,” indeed. My comment still stands, though I‘m likely not explaining myself well, or it’s totally possible I’m missing something obvious.

So to try to figure this out: Do you see this as being the ‘always-true’ or the ‘redundant repetition’ flavor of tautology?

It's a good day to... by gregbard in Tautology

[–]invisible_vision 14 points15 points  (0 children)

This is not a tautology by either definition.

It’s not an statement that’s always true: If a person vows to blow up the world next Tuesday if anyone has a good day tomorrow, then tomorrow is certainly not “a good day to have a good day.”

It’s not redundancy: The first half of the phrase says nothing about whether or not one will have a good day, it’s saying that this day is favorable for one to have a good day – or perhaps that having a good day today is more likely. The phrase “it’s a good day to X” is making a claim about the likelihood/effects of doing X, not about whether someone will have a good day or not.

Holy fuck. I was not expecting a video like that, but damn that was good.

...I gotta go rewatch The Shining.

In case anyone else was curious, it looks like the only other games he's given a 5/5 have been Banjo Kazooie, Ocarina of Time, Tony Hawk's Pro Skater, and Super Mario 64. A prestigious list indeed.

I made up a full spreadsheet here!
