Quick sharpie sketch of David Goodstein, from The Mechanical Universe science TV show (and many popular books). I loved The Mechanical Universe; it’s what I watched prior to reading The Feynman Lectures on Physics. Again used the non-repro blue to rough it, focusing very, very hard just on the shape of the face and not the rendering. I actually like how the shape came out.

P.S. And wrote 2300 words too.
