Following my previous entry, I stumbled upon this illustration by Ernst Haeckel, from Art form in Nature, dating from the beginning of the twentieth century. This one in particular, bryozoa, caught my attention because of the simplistic depiction of intricate semi-transparent structures. His illustrations serve us as a reminder to end the hegemony of Gaussian filters over sharp details in today's computer graphics.

Evolution of Man

The Ascent of Man, created by Rudolph Zallinger and published in Early Man by F. Clark Howell, parodied numerous times, continues to be a landmark in scientific illustration. And it does so despite the linear simplification of an otherwise complex tree, which has led, unfortunately, to misinterpretations that many of the detractors of evolution claim as proof of its falsity. I personally stand behind Carl Sagan's words: "Evolution is a fact, not a theory. It really happened".

Somewhere in Downtown Napa

Somewhere in Downtown Napa, I found this rather confusing map, where you can be in two places at the same time. Despite the ontological implications of the sign, I guess you can ultimately find yourself by identifying the stores around you, in which case, of course, the purpose of the pointer is defeated. Maybe they bought it at a two for one poster sale.

The Pioneer Plaque

With the hopes of being intercepted by alien forms, NASA sent this plaque on Pioneer 10 in 1972 (and then on Pioneer 11 the next year). It shows, among other things, the relative position of our sun with respect to 14 pulsars, the figures of a man and a woman, and our own solar system. I will not write about the cleverness of the encoding, that should be deciphered by an extraterrestrial being, but about our own fallibility. The solar system depicted, inevitably, Pluto, which, together with Ceres and Eris, was degraded to a dwarf planet. So I imagine two scenarios. One, an alien life form finds the plaque and then us, but then dismiss us as a possibility after finding eight big planets and three smaller ones, instead of nine. Or two, we send another plaque, with our updated knowledge. And, in the event we should discover new bodies in the solar system, we would keep on sending plaques until we have filled the galaxy with our own gold coated spam mail. Or, we leave it to the software companies and the new plaques will become the service packs of interstellar travel.

The Catalhoyuk Map

Catalhoyuk is a place in Ankara, where archeologists found an ancient settlement. This image is a recreation of a painting found in the site, depicting the structure of the settlement and an erupting volcano in the background. It is often referred to as the "oldest map" (so far). Why is it so interesting? Well, for starters, this map pre-dates writing. But what I find most interesting is the fact that it is a 2D, aerial representation of the city, rather than a landscape painting of their houses. It is, in fact, an abstract representation of the spatial surroundings. Unlike other neolithic paintings, which depict animals from the point of view of the hunters, the Catalhoyuk map shows the city from a viewpoint held by none.
