There is a 2,000-year-old wonder called the “Antikythera mechanism.” I plan to talk about it, but I’ll start in 1993 when I got some nifty drawing software and took it into my head to try to compose an image resembling a coin with a two-faced Janus head on one side. Since the program allowed me to position visual elements precisely I decided to put small circles like a string of beads around the edge of the coin. This proved surprisingly challenging. The diameter of the coin was 7 inches, so its circumference was roughly 22 inches (2 x pi x (7/2)), but the string of circles needed to be just slightly inside the circumference of the circle. And the circumference of each little circle was a line that had thickness, and I wanted those little circles to overlap at their points of contact.

Something I realized pretty quickly was that I would make myself crazy if I tried to draw every single little circle and hope that they would all meet up nicely when the two ends came together over a 22 inch circular span. So instead I divided the 7 inch circle into eight 45-degree slices, fitted the small circles along the curved edge of one of the slices, then made seven copies and arranged them around the circumference of the coin. The result was not perfect uniformity, but it did not offend the eye. And since I was only drawing, and not trying to manipulate solids, or needing to have my work mesh with something else, what I came up with was sufficient.

Gold Silver Mercury

Before physics and chemistry there was alchemy. The alchemists asked questions that were beyond the resources available to them to provide satisfactory answers. Many of the gaps between what they wanted to know and what they could find out through experimentation were filled in with speculation and imaginings – usually added on top of the speculations and imaginings of those who came before them. (Hmmm…any chance we still do that now?)

Substances, like people, generally behave in fairly predictable ways consistent with their personalities. Since the alchemists were intensely interested in substances, and studied them over long periods of time, they felt they knew them. And they saw a little of themselves in their glowing caldrons.

When the alchemists projected aspects of themselves on the substances they studied lots of internal stuff – psychological stuff – was revealed. The image above is composed of 12th Century alchemical symbols arranged to suggest the ongoing process of individual experience.

Sometimes stuff flows from through  to  and sometimes it flows the other way.
