Fermi Epicycles: The Vela Pulsar's Path

I saw a TV show about art on PBS last night. Different artists talked about and demonstrated the making of their art. One older man (I won’t mention any names) was into making large colored rings with curved lines passing through the design. I’m sorry, but he never really got through to me why this was art. He did convince me that he was obsessed with drawing nothing more than colored rings with curved lines. Sometimes I wish that TV was more interactive, like this forum, where anyone can give feedback to the originator of a topic. I would have mentioned Fermi epicycles to this artist, but I doubt that he would have listened to me. I suppose that in NYC a one man show of different colored rings with a few curved lines would interest a few serious lovers of modern art, but out here in the heartland, we would be more interested in the complex designs of Fermi Epicycles, hands down.

lazy sot, any fool can make rings with curved lines

it would take an artist to make rings with straight lines

I agree, Denny, if you could make a ring with straight lines, unless there was a whole lot of them, then you wouldn’t need any curved lines at all. But what I am talking about is, given a basic ring shape, the artist inspiration is in the placement of a few curved lines within the matrix of the colored ring. Give me a break, I could make an infinite variety of rings like this, and I wouldn’t think of it as art. I would be ashamed to stand in the exhibit room while people were coming in to view my “work”.

Talking about pulsars, they are kind of scary. I don’t don’t think that I would want to own a house on a pulsar.

had one o’these once…

didn’t look anything like the picture, preplastic

Yes, the spirographs are very interesting. As you would expect, that is all done on the computer now. However, at the bottom of the wikipedia page there is mathematical analysis of the spirograph. These days I quickly turn away from a whole page of equations. It reminds me of all the long hours that I spent trying to grade high school algebra and geometry homework. At the present I would prefer to find contentment in cutting a nice looking and nice sounding flute embouchure without the mathematical analysis of how it works.

Yeah, but the Spirograph was two-dimensional & that Epicycle is three. Maybe if you integrate the equation for a good Spirograph curve you might get something like a reasonable Epicycle.

We might start by defining “reasonable”. Here are some Epicycles:

that certainly illustrates why I’d come here for a definition of “reasonable” :smiley:
