Learning en passant

During your PhD, you often have to learn things that will not show up in your thesis. Your program of choice for data analysis, for example. So far I have managed to avoid delving into Origin, and squeeze by with the trifecta of Matlab, Mathematica and COMSOL. Or drawing engineering drawings. The CRPP has dedicated draughtsman, but often it is much quicker to draw a simple piece yourself. I am not up to snuff yet, in that my drawings are not norm-compliant, but they have become good enough that the people at the shop don't need to get back to me to ask for interpretation anymore. Here is a drawing I did yesterday morning, part of my next experiment, as soon as I can figure out my nasty resonance-problem.
