Life on Mars: Artist concept drawing
Life on Mars: Continuing our recent Mars theme, this is a 2005 Nasa futuristic artist concept drawing of how life on the red planet might look. It is hoped within a few decades this science fiction scene will become science fact, and life on Mars will become a reality. (Why? There are concerns the colony is needed to mitigate against a growing list of existential threats to civilization. Not the least of these is mineral and rare earths depletion, which new technologies like the Martian colony might address. We’ve previously talked about existential threats to humanity as well as concerns about peak rare earths in our previous posts on the Singularity.) A version of this article originally appeared as a photo post on our Instagram feed. (more…)… Read the restRed Sky Rover: self-portrait of Mars Curosity at Gale Crater
Red Sky Rover: this is a self-portrait of the Nasa Mars Curiosity rover taken on Oct 31 2012 at Gale Crater. (We’re continuing on Martian theme, started with yesterday’s post on self-replication.) This photo was taken at “Rocknest,” in Gale Crater where the first scooping missions took place. (You all remember your Martian geography so you know exactly where Gale Crater is, right? Well, the place already has its own Wikipedia entry, which is more than one can say about some places on Earth. All it needs now is a postal code and a real estate agent. Maybe some fancy ads featuring models lounging near an (indoor? terraformed outdoor?) pool beneath the red sky. Maybe leave out the red sky and show only the faux tropical indoor pool. “Gale Crater condos starting in the low millions. Invest now; they aren’t making any more real estate.” Oh yes nasa and other space programs are.)… Read the restmath pattern art: mathematical quilting & design
Mathematical quilting and math pattern art & design: shown here are 17th century Italian quilts made from mathematical patterns. Yesterday’s Hamming metric (or Hamming Error Correcting Code) quilt got us thinking. Turns out there is a branch of quilting making (or perhaps a branch of mathematics if you will), “mathematical quilting.” It looks to math — polynominals, Rule 90 cellular automatons, etc., for inspiration in quilt making and pattern art. Shown here is so called “Florentine work” because these popular quilt designs are based on mathematical patterns originally found on chairs in the Bargello Palace (today an art museum) in Florence Italy. These chairs date to at least the 17th century, if not earlier. There are many types of these quilts, which are typically very colorful. The quilting requires precise counting of squares so that the pattern art design conforms to the mathematical pattern chosen. So yesterday’s crazy quilt, in which math creates art, isn’t unique.… Read the restWolfram mathematica: data visualization example
This is example of visualization using Wolfram Mathematica, a commercial software package. We’ve previously discussed some of Wolfram’s other products and ideas in an earlier post on digital physics and cosmology as well as in our posts on IBM Watson. One of the reasons that data visualization remains something of a black art is that there are so many data visualization packages out there. Each package has its strength in a few kinds of plots or types of visualizations. Some of the better packages are commercial (and, unfortunately, not necessarily inexpensive). The high prices mean the experience of any practitioner is likely to be limited to a few commercial visualization packages over the course of a career (since most sites will only license a few packages). Open source data visualization packages are therefore very powerful, since they potentially combine the best of free tools. There are very good free tools out there.… Read the restRecent Posts
