One of the illustrations I had in my thesis! I had little drawings as chapter headers for a few of the chapters :) This is the Newtonian Calibrator prototype that was tested at LIGO Hanford.
@ASleepyWanderer I have to say, this looks so beautiful and inspiring. Now I want to draw all over my field notebook, but I doubt I will reach this level! Did you get inspiration from a particular kind of art?
