Who Owns the West? Federal Lands 2014

Posted by & filed under Code, Computation, Data, GIS, Mathematica, Wolfram, Wolfram Language.

This map is a spectacular example of how data reshape public perception and knowledge. Very simple in nature it nevertheless shocks an average citizen by giving clarity to the data usually buried in obscure tables. East versus west, federal versus private, – the contrast is sharp and reverberates in the minds entangled with American history. […]

Interactive 3D Calabi-Yau Surface

Posted by & filed under 3D, Code, Demonstrations Project, Graphics, Mathematica, Sketchfab, Wolfram, Wolfram Language.

Wolfram Language allows creation of computational 3D models. These are different from those you can build with your own hands such as SketchUp etc, because computations are often intrinsically different from the way humans see and think. Let’s take for example Calabi-Yau Surface. It is a mathematical object and it is hard to imagine it. […]

ASCII Tree

Happy ASCII New Year ;-)

Posted by & filed under Art, CDF, Code, Graphics, Mathematica, Wolfram, Wolfram Language.

I can occasionally appreciate a nice ASCII art design. But the better is the design, the more manual and custom approach it needs – or so it seems. It is actually quite challenging, if you think about it, to transform a known image or shape to a limited medium using finite set of geometries. So […]

Sin Tree

t * sin (t) = Christmas tree

Posted by & filed under Art, Code, Community, Graphics, Mathematica, Wolfram, Wolfram Language.

Another code sample from Wolfram Community. I noticed that a discussion about programming a lighted Christmas Tree from a simple equation t*Snt[t] became very popular on Reddit. It is connected to a project a programmer developed. I thought how fast we can make it with Wolfram language? Here is the result with slight flickering 😉 […]

Iconography for Elementary Cellular Automata Based on Radial Convergence Diagrams

Iconography for Elementary Cellular Automata Based on Radial Convergence Diagrams

Posted by & filed under App, CDF, Code, Demonstrations Project, Mathematica, Publishing, Wolfram.

My recent publication at the Wolfram Demonstrations Project: “Iconography for Elementary Cellular Automata Based on Radial Convergence Diagrams“.   Consider a complete set of initial conditions for a finite elementary cellular automaton (ECA). This set can be indexed by integers using a Gray code or a binary to decimal conversion. During the ECA evolution, the […]

Complex numbers, beautiful surfaces and Mathematica

Posted by & filed under Code, Graphics, Mathematica, Wolfram.

A few lines of code in Mathematica can produce beautiful images. Take as an example this simple but spectacular result of singularities in complex plane: Plot3D[Im[Sec[(x + I y)^4]], {x, -2, 2}, {y, -2, 2}, Mesh -> None, ClippingStyle -> None, PlotStyle -> Directive[Orange, Opacity[.8], Specularity[White, 20]], PlotPoints -> 50]
