I think this is a math joke more than anything else. The last line drawn is parallel to the first, so if he wouldn't abort he'd have to draw the line forever (two parallel lines never intersect). Euclidean space ftw.

It might help people make their stars/pentagrams look a little better to know that for a 5-pointed star, the arc-length between the points is 72 degrees.

Also, an inverted symbol, whether cross or pentagram, traditionally symbolizes a higher level of holiness. Most of those metal bands have no idea what they're doing.

There are times when I consider drawing a short line segment that connects the head to the torso; as though there were an elongation of the spine which reached above the shoulders.

However, I quickly dismiss such flights of fancy, and recapitulate* from all artistic pursuits.

I think a (theoretically) exact method to draw a pentagram would be like following:

1. Draw a horizontal line with length l1, and end points A, B
2. Calculate l2 = l1/phi, where phi is the golden ratio (sqrt(5) + 1)/2
3. Use a compass to find the point E' below the line AB with a distance of l2 from A and B
4. Draw lines AC, BD with length l1 that pass through E'
5. Use a compass to find the point E above the line AB with a distance of l1 from C and D
6. Draw the lines CE, DE

Diadem wrote:I ... don't get the comic.

At first I thought he was accidently drawing a star of David, and that is why the commentator wanted to abort (because of associations with nazism). But it's not a star of David, nor could it become one. Then I thought maybe it's a pentagram the commentator is worried aboug, for its association with Satanism. But it's not a pentagram either.

So what symbol is the drawer accidently drawing that has the commentator so worried? I do not get it.

Perhaps the commentator is worried that the drawer is drawing it wrong. But that's not a joke. Besides he isn't. He's only drawing it wrong if he wanted a pentagram. But in that case he's already wrong at the 3rd stroke, when the commentator still says 'steady as she goes'.

So I'm just totally confused at this comic.

If I'm not wrong, there's just one person who wants to show how to draw pentagrams (hence 36°), but who doesn't realize that already the third line is wrong (it should be horizontal).

P.S.: Seems I'm in the invoke Air / banish earth group

Fool! You do not understand the importance of the direction in which you draw your pentagrams!

As the above diagram shows, in this comic Randall had attempted to invoke spiritual energy. The point of the comic was that the drawing of a pentagram should not be taken lightly: as he was drawing the pentagram for invoking a spirit, he realized that the approaching spirit was malevolent, and immediately aborted the invocation.

You, on the other hand, are drawing Earth-banishing pentagrams. It is no wonder that the state of our planet is in environmental decline, thanks to heathens such as yourself...

I draw pentagrams in a non-Eulerian style (that is, I lift the pencil between strokes, and don't start the next stroke from the end of the previous one). What is the effect of that?

In practice, there are 3840 ways to draw a pentagram drawing each of the five sides with a single stroke. The illustration rileyrulesu provided gives effects for 10 of the 3840. What do the other 3830 do?

Of course it's a Jewish religious symbol. And it's fine for Jews to use it. But it's one of those symbols that you really can't use as a non-Jew without very unfortunate implications.

Can't speak for the European perspective, but from an American perspective there's nothing negative associated with the Star of David.

I agree with this. Just because the Nazis used a Jewish symbol (not a religious symbol, incidentally) to designate Jews doesn't turn it into a Nazi symbol or imply that a non-Jew who uses it is a Nazi sympathizer. Obviously, if he's chalking it on doors or something, that's a bit different, but the same would apply to the word "Jew" (or any other ethnicity, for that matter). Symbols stand for what they stand for; it's context that gives them implications beyond that.

I don't know what that means.

But there are plenty of words that can only be used by members of the group it applies to, at least without unfortunate implications. But no doubt cultural associations are different in the USA, so it could be a European (or maybe even just some parts of Europe) thing.

Zylon, hush you! There is no place here for rationality! What we need is wild speculation and anarchic misrepresentation! Saying this is *just* a comic about having difficulty drawing a star is like saying that http://www.xkcd.com/887/ is just a representation of searches in google about various future points in time. It's so much more than that! It is a prophecy! So, please, let's have a little less common sense and a little more fanciful bullshit. We'll need all we can get if we're going to catch up with the PUA thread.

No, seriously, in the US, the Star of David is simply associated with Judaism. There's no popular conception of it as the mark the Nazi regime made of it. It's as common as the cross or the star and crescent, and it's neutral enough for bumper stickers.

I've been banishing Earth, too, but I'm terrible at it. (This was very GOOMHR for me - I've done this countless times.)

But just because there's a link doesn't necessarily mean there's a connotation. Again, it may be US vs Europe, but I've never heard anything about the Star of David being off-limits like the Swastika is.

Yep. I'm going to have to agree. I think you'd be hard pushed to find someone above primary school age anywhere in Europe or America who doesn't have at least a passing familiarity with the existence of the Holocaust, but it would be a misguided person indeed who assumed that the Star of David in any way symbolised naziism.

When I was little, my cousin taught me a simpler way of drawing five-pointed stars. You draw a capital A but extend the horizontal stroke out to the sides. Then you just draw the last two lines by connecting the arms to the feet. It's not as fast but it's easier to get it to point in the direction you want and make it symmetrical.
