Thanks for the quality.

Vi Hart is *quality as usual.

Of course, if you wish to know why some of Earth's most magnificent structures (like grouped mountain ranges--looking at them from over head) many look peculiarly like pieces of fractals, then spend some time looking into the "Golden Number" or the natural number, but as science refers to it: Euler's number (the constant: e). It is related to a great many interesting things.

Beyond seeding fractals, it is used in math a lot, Golden Spirals and the Fibonacci Sequence are part of it. It can be seen in nature in many places: those mountain ranges, trees, our cardiovascular system, and even shells. It's one of the most interesting constants we have and it is related to many structures that occur naturally. Which sometimes makes it appear that natural origins--structurally--may have their beginnings through this number via things like the Golden Spiral and of course fractals.

Just a little information to help make a piece like this seem even more impressive.

Not attracted to her at all and I am a sucker for tall, skinny, pasty, artsy, intelligent, brunettes with dark brown eyes.
It is ok though. It wouldn't work out, even if I were attracted to her. She hates me and I know it, already.
Incredibly, well done, simple and thought-provoking video though.

I love this girl.

But is she cute/hot? What does she look like?


Not bad.



They all hate me.

Not attracted to her at all and I am a sucker for tall, skinny, pasty, artsy, intelligent, brunettes with dark brown eyes. She had so much going for her; but I'm sure she'd rather figure out the probability of failing?

It is ok though. It wouldn't work out even if I was attracted to her. She hates me and I know it. I can tell simply by the way she speaks and her body language. I don't know, usually when I date a girl/lady/woman, though frustratingly rare - it's usually like they knock my socks off the second I see them because we immediately have this intense connection and she usually is... tall, skinny, intelligent... maybe I have some sort of Freudian problem. LOL.

Incredibly, well done, simple and thought-provoking video though.

I think fibonacci sequences are also to be found in such patterns as the erosion patterns of coastlines, the altitude formation of mountain ranges, the migratory patterns of birds and undulates, the rise and fall of the tides...

Dan Secrest - The reason why there is a gap in these "triangles" is actually related to fibonacci's sequence. But I wont go there. The easy solution is simply because those are not triangles. Each has 4 sides. The red triangle has a different slope than the green. The red triangle has slope 3/8 while the green has 2/5. Therefore, in the upper "triangle" there is increasing slope along the hypoteneus and in the lower there is decreasing. The short short answer is that the areas of both triangles are EXACTLY the same, but the lower triangle has a gap to make up for the different slope it has on the hypoteneus. If anything, these resemble non-euclidean triangles because there angles add up to over 180 degrees.>> ^dannym3141:

Notice how easily the pieces slip into place in the first layout compared to how he has to force them into place on the second layout.
It's related to this:

did he even mention fibonacci? as a math person I don't find this mysterious.
