The Analemma
August 6, 2002 2:01 PM   Subscribe

A very well designed site on the Analemma. Don't be scared off by the math, as there are excellent diagrams and quicktime movies on this difficult to visualize phenomena. Difficult, but not impossible, to photograph (probably less than 10 photos are in existence) Ulrich Bienert came close, and has a gallery and some tips if you're so inclined.

Sorry, but I'm not inclined to view those frames, bevelled rollover buttons, and textured background as "well-designed," but the astronomy and analemma photos are pretty cool.

I was not familiar with the term 'annalemma' It leaves me wondering if there are other un-googlable photos of this out there by patient photographers who simply wanted to map the progress of the sun's path through the sky. Thanks.

Uh-oh, I think we blogdotted ;)

I had a copy of EZ-Cosmos on my old IBM 286, and I enjoyed experimenting with the solar system animator using different time increments. It's always amazing to see the strange shapes the sun and planets form in their rotations through the hours, years, and centuries.

(Oh, wait, it's back. Nevermind.)

Ahhh! This brings back a horrible college memory. I once failed a phy. sci. paper because I explained the rotation of the earth without referring to the 23.5 degree tilt on it's axis. Sure I had the whole tilt thing down, but did not include on it's axis. Damn that professor.

I have never heard the term annalemma. Good link, thanks!

From my recycling of a memepool post about back in January, a cool applet that saves you a year of time-lapse photography, or at least a lot of convoluted mathematics.

Boy, aren't we the design snob, brownpau. Though it certainly wouldn't win any web guru awards, I found it attractive and easily navigated.

Related: analemmatic sundials, and the influence of the analemma effect on the development of modern timepieces, and thereby our modern conception of time. There's grammar, etymology, and math. The analemma is more accurately the path traced by the shadow of something obscuring the sun, that is, the representation of the path. Also: A physics & astronomy sundial showing an analemma path, and an analemma sundial in a frosted window. Searching on analemma+sundial gets you tons of things along this line. There's also a lunar analemma to observe.

Well, I just think it needs a bright pink background and a 1.2MB Flash intro to be really cool. ;D

As someone who prefers simple and unobtrusive functional design over 'impress your net-nerd friends with the latest font du jour, hot photoshop filter and script' pizzaz I disagree.

Of course this reminds me of the analemma cave calendar that Tom Hanks's character used in Cast Away.

Am I the only one who, reading the article much too quickly, read it as "Anal Emma"? Until I read the part about not being afraid of the math I thought someone posted a porn link.

Maybe it's just me... :)

In elementary school we used the shadow method (much smaller scale) for the school year but on a weekly basis.

It was enlightening, I wonder how this would work using the moon.
