Self-replicating 3D printer: von Neumann machines on Mars?
Is this self-replicating 3D printer a von Neumann machine that will someday go to Mars? Yesterday, we experimented with our idea of Instagram to 3D printed jewelry for the more popular monochrome photos in our feed. The technology worked at some level (we have jewelry on Shapeways now, based on a previous IG photo post). But it took too long and too many artistic decisions to get it there. It wasn’t quite blinking lights automatic the way our earlier virtual fashion shoot could be. So this is a good time to step back and explain what 3D printing is or can become, for those we are less familiar with it. This is Mandel, a version of RepRap. RepRap is an open source hardware project to build a fully self-replicating 3D printer. That’s right, a 3D printer that can print a copy of itself. We’ve discussed the concept of self-replicating machines previously in posts on cellular automata.… 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 restIOT Internet toilet senses disease (and talks?)
We promised to return to Earth after our previous photo post discussing 3,000-year-old Chinese sunspot observations and catastrophic space weather. How else could we do this other than another important Asian trend that we missed: Internet-connected toilets. Don’t laugh, this isn’t a Google April Fools joke (although Google reportedly has installed an earlier non-IOT model of these “advanced” toilets by the same manufacturer, Toto of Japan, in their offices). IOT Internet toilets actually make a lot of sense. These Japanese units from Toto can automatically detect disease via blood glucose, blood pressure, and BMI sensors. They can transmit this health information via WiFi. As they say in startup world, this is obviously a billion dollar idea. All of this can then be integrated with something like Apple’s HealthKit. Thus, they can be integrated with the rest of iOS. So, in the not to distant future, your toilet should be able to talk to you via Apple Siri.… Read the restWolfram Alpha, von Neumann & digital physics
Continuing our discussion of fractals, digital physics, self-replicating spacecraft, cellular automatons, and von Neumann machines, this is view of a different part of the Mandelbrot Set (produced with a different viewer). Answer to the question at the end of yesterday’s IG photo post involves Stephen Wolfram of Mathematica fame. His company, Wolfram Research, makes the Wolfram Cloud Programming Language, a potential competitor to something IBM Watson-like, which we discussed in an earlier blog post. This language powers Wolfram Alpha, which is currently part of Apple Siri. So, if you’ve used Siri you’ve probably used this software. When not developing technology that became part of Siri, Stephen Wolfram wrote a bestselling (and somewhat controversial) book on Cellular Automatons, A New Type of Science. In one information-centric view of the universe attributed to Wheeler and others (sometimes called “digital physics”) the universe can be thought of as a collection of cellular automatons (or, equivalently, a Turing machine or perhaps a quantum computer).… Read the restRecent Posts
