I think I've just encountered the highlight of my visit - a poetry reading by Nobel prize-winning chemist Roald Hoffmann.

Coincidentally, I've been thinking a lot about poetry lately, and how a poet can convey their thoughts. I am not brave enough to attempt to write anything other than a jaunty limerick myself, so I have a good deal of admiration for anyone who can convey a complex thought in an abstract, but senseful way.

And Hoffmann just spent an hour in the middle of a busy, bustling exhibition hall, packed full of people trying to sell mass spectrometers and the like, with a crowd of people captivated by his poems that cross from hard-core science to his childhood experience growing up in Poland during the war, to more philosphical matters.
