Travelling Waves in Guinness

That was what the applied math colloquium was about today. (Can you believe we get paid to study and discuss stuff like this?) Actually, there is (unsurprisingly) some very serious and important science involved. The official name of the subject is "two-phase flows." I'd include an abstract or link to the speaker's webpage, but I couldn't find either. So this will have to do... (For what it's worth, the "practical session" is going on now. The standard procedure is to go to the pub after the applied math seminar, but I have an event to attend at 6pm, so I won't be able to hang out with the gang today.)
