The other day, some folks on Twitter were trying to explain NMR:
@sciencenotscary: There's, um, some precessing and relaxation times and...uhhhh...So, for amusement, I am offering a fine prize to the person who can offer the funniest, yet most accurate explanation of a chemical spectroscopic technique. Nominees to be decided by commenter acclaim, winner to be decided by a panel to be determined. Deadline for entry in the comments or by e-mail by midnight (Eastern time), July 24, 2015.
@chemprofcramer: rotating frame! rotating frame!
@chemjobber: There's a radio pulse, and a spinning thing and it goes ding!
The fine prize: A 1 pound bag of hard candies, a certificate fit for framing, 50 of the finest Chemjobber business cards, a handwritten thank you note (by me) and a $10 Starbucks gift card.
(A serious note to grad students, especially fellow organickers: understanding the fundamentals and the details of spectroscopic techniques is important. Asking questions about them during oral exams is perfectly cromulent, in my opinion.)
