Just seeing this. This sucks. I was actually just thinking about Doc a few weeks ago.
I had the pleasure of him being my professor for honors physics. 5.0 credit class that met an extra day during the week. So in our situation the regular class of 50 or so General Physics students (4.0 credit hour) + honors physics students met M-Th 11-11:50 all with the same instructor, and then the small group of 5 or so honors students met with Dr. Meriwether on Fridays from 11-11:50. He was head of the physics department at that time. The structure of the Friday "class" was basically a discussion amongst our small group of interesting topics in physics, no extra tests; just an amazing experience. Our only homework was to read sections of Carl Sagan's The Demon-Haunted World each week, which truthfully was not work. I read the book twice during that semester. We would also use the time as office hours to have Doc re-explain any class topics from the week that may have been unclear. Of all the honors classes I took, that one was by far my favorite.
Great mind, great teacher, great person. RIP Dr. Meriwether.
