It happens gradually, thorough the month of May. A few arrive during the first week, and one hardly notices. More come during the second week, and the third... and by the end of May, the cafeteria is a very different place at lunch time than it was in April.
The summer students are here.
Every year, we get a batch of students, from undergraduates to those about to get PhDs, who arrive by the start of June and stay through some time in August. We have some 8 to 12 weeks to give them useful and interesting work to do, to provide them some training, to advise them on where to take their schooling and careers... and, we hope, to interest them in coming here to work after they graduate.
We usually set up some poster sessions — one to show the students the various projects we're doing here; one to let the students show us their work, both what they're doing with us and what they're studying back at school. At the end of the summer we ask them to give brief seminar presentations, showing us what they've accomplished during their stays. And we set up some social events to make them think (bwa-ha-ha!) that this is a fun place to be.
I'm sure such programs existed when I was in school, but I hadn't heard of them. I wish I had — it would have been far more interesting (and better-paying!) than going home and working at McDonald's for the summers, enriching as that experience was.
And so the average age here in the office has just dropped a bit, for the nonce. It's pretty groovy.
Or it's “teh r0x0rz!!!”
Or however they say it....
