Thesis as localized repulsor

This PhD comic was doubly true for my thesis. First, the phenomenon he describes: every time I started to do anything else, the thesis beckoned. There was a constant refrain, "must work on thesis." But actually sitting down, I found the text physically repulsive. Once at the keyboard, it was constant work just to force myself to type.

For me, it was true in a second way: that local repulsor model describes the control scheme I used for multi-robot formation control, based on Leonard's work at Princeton. (That is, the robots were all attracted to each other from a distance, but were repulsed when they got too close)

I am highly amused.

Sentence of the day

Tyler Cowen says,
‘Overall I seek to narrow rather than widen the following category: "cannot be praised without accompanying symbolic denunciation.”’
Can’t possibly agree more.
