I like the visual theme today, and the unusual, unchecked "E" and "F" were a nice touch. It didn't put up much of a fight, but it was not without a few tricky ones, at least for this solver. To wit, the "A" crossing of HABANERA (2D: Cuban dance) and WAC (20A: W.W. II female) was an educated guess. "Women's Army Corps?" OK, perhaps I ought to have been more sure about that.
I do not like seeing SUH (10D: Ndamukong ____, 2010 N.F.L. Defensive Rookie of the Year) in the grid. I thought Will Shortz maintained standards of decency, but apparently he does not watch enough football to realize that Suh is a dirty, overly-aggressive player.
On the other hand, I applaud the inclusion of the genius FEYNMAN (48D: 1965 Physics Nobelist Richard). Always nice to be reminded of him. And perhaps he could have explained to me how OBELI were 17A: Division signs. The obelisk is used in Greek and Latin literature to indicate corrupt or possibly corrupt words or passages. In the books I've lately read, the "dagger" (†) is used, and I thought that was an obelisk, but now I learn that it is the typographic equivalent of what I had previously called the "division sign" (÷). "Obelisk" itself, means "little roasting spit" and symbolized the skewering or cutting out of bad material. (According to Wikipedia.) Huh. Welp, I've learned something else through the puzzle!
The inclusion of two unrelated fifteens in this grid seemed a little odd, especially since they had nothing to do with the theme, but both were decent enough entries - I preferred SLOWONTHEUPTAKE (11D: A bit dense). And the eights (yes, even "Habanera") were all fine. Some short crosswordsy stuff, but nothing too egregious.
