Is Mathematics Beautiful? First part: Surfaces
“Mathematics, as much as music or any other art, is one of the means by which we rise to a complete self-consciousness. The significance of Mathematics resides precisely in the fact that it is an art; by informing us of the nature of our own minds it informs us of much that depends on our [...]

Installing Enthought Tool Suite (ETS) on OpenSUSE 11
Today, I tried to install Enthought Tool Suite on OpenSUSE 11, with the help of my old post. For the moment there are no packages for OpenSUSE. I had to checkout their repository and build the eggs, in order to install the suite. The mentioned tutorial worked but of course that I had some minor [...]
Personal bibliographic management software
Handling references and bibliographic information is an essential part of all research. If you are writing just one article or just your diploma thesis maybe you don’t need to use this kind of software because you will not have a lot of references. BUT, if you are writing A LOT of [...]
Animations in PDF using LaTeX
I am using LaTeX (started with LaTeX 2.09, followed by LaTeX 3e) for everything technical and scientific (reports, articles, master/diploma thesis, presentations – yes, I am preparing my presentation with it, posters, letters, ..). In the last year I changed to pdfTeX in order to obtain directly pdf file output without intermediate steps like [...]

Graphics with Gnuplot from C and Python language
If you are doing a lot of calculations/simulations, like me, using C or/and Python language, you also need to visualize your simulated data. One way to do it is just to generate/write a “data” file and plot it with your plotting preferred package after the simulation is finished. But maybe, sometimes, you want to see [...]
