The time to develop the equations is before the conference.
On the way to the conference, at least I rehearse the talk.
I have my talk on powerpoint slides printed out on 8.5 x 11 paper, along with the title page.

Geeze! I do math for **fun** . I am leaving for Texas tomorrow for 6 weeks on the beach and plan to thoroughly review all the problems in an engineering level physics book. I do that for personal entertainment. Last time I was on the beach I completely revisited Trigonometry and Geometry. Next time I fly I better leave my calculator, compass, and ruler in my check-in bag.

Surely the press wouldn’t throw together a story without all the facts. /s/
