Two (2) Ig Nobel events on the same day, in different cities:
Ig Nobel chemistry prize winner Theo Gray (inventor of the four-legged periodic table table) can and and will (thanks to some happy coincidences) join me in doing a talk at NIST, in Gaithersburg, Maryland on Friday morning, April 25, at 10:30.
Friday evening, I will be appearing a few hundred miles north of there, as part of the Lost Lectures, at a somewhat secret site in New York City. (Theo will not be part of that, but another Ig Nobel personage will.)
