Smith Charts for All

I've covered several different programs that are useful when doing electrical engineering in the past. In this article, I want to look at a program called linsmith that helps you do calculations or see how different parameters behave. more>>

Stepping into Science

In past articles, I've looked at several libraries or specialist applications that can be used to model some physical process or another. Sometimes though you want to be able to model several different processes at the same time and in an interactive mode. more>>

Nightfall on Linux

I've looked at general astronomy programs in the past that are helpful for many tasks you might need to do in your stargazing career. But, several specific jobs are more complicated and require specialized software to make relevant calculations, so here, let's take a look at Nightfall. more>>

Astronomy for KDE

Although I have covered a large number of science applications in the past, I haven't really looked at too many options available within the KDE desktop environment. This has been due to my own biases in using a GTK-based desktop environment, but now I'd like to look at some of the packages available for people who really like to use KDE on their own machines. more>>

Makeblock's mBot

The new kid-friendly mBot from Makeblock is marketed as a Science, Technology and Mathematics (STEM) educational learning tool. more>>

Symbolic Math on Android

For this article, I'm returning to portable science software on Android. In a previous article, I looked at a program called xcas/giac. This program is an open-source engine that is used to handle symbolic manipulation of mathematical equations. Because it is open source, it has been ported to several different platforms. more>>

Pluto and Linux, the Underdog Superheroes

I'm a space nerd. That's probably not a surprise, but just how deep my nerdery goes might be. I have just about every space photo NASA has ever released. I schedule mission briefings on my Google Calendar as if they were specifically for me. I used to make my kids watch Shuttle launches on our TV, even if they were doing homework! more>>

ABINIT for Chemists

The single largest group of users on high-performance computing clusters has to be the chemists. Their CPU-year count is definitely at the very top of the list. Because of this heavy use, several different packages have become standard tools that most computational chemistry researchers use. more>>

Symbolic Algebra Everywhere

Previously in this space, I have covered software packages like Maxima that can be used to solve symbolic mathematics problems. Several packages are available that can do those types of calculations. In this article, I discuss Xcas/Giac. Xcas is the GUI interface to the system. more>>

Recipy for Science

More and more journals are demanding that the science being published be reproducible. Ideally, if you publish your code, that should be enough for someone else to reproduce the results you are claiming. But, anyone who has done any actual computational science knows that this is not true. more>>

Science on Android

I have covered a lot of different scientific packages that are available under Linux in this space, but the focus has been on Linux running on desktop machines. This has been rather short-sighted, however, as lots of other platforms have Linux available and shouldn't be neglected. So in this article, I start looking at the type of science you can do on the Android platform. more>>

Finite-Element Methods for PDEs

One of the common classes of equations that is encountered in several branches of science is partial differential equations. So in this article, I look at a software package called FreeFem++ that is designed to help you calculate these partial differential equations. more>>

Doing Astronomy with Python

One of the things that makes Python so powerful is that you can find a module for almost anything. In this article, I cover Astropy, which was originally developed by the Space Telescope Science Institute for doing astronomy calculations like image processing and observatory calculations. more>>

General Relativity in Python

I have covered several different software packages for doing scientific computation in Linux Journal, but I haven't spent as much time describing available libraries and the kind of work that can be done with those libraries. more>>

Physics Analysis Workstation

CERN is the European Laboratory for Particle Physics. It has been in the news quite a bit lately with the discovery of the Higgs Boson at the Large Hadron Collider. Something that many people may not know is that it also has a long tradition of developing software for scientific use. more>>
