Written one afternoon while teaching a physics practical class in the Cavendish Laboratory
(6th March 2007)
In the first year physics practical,
One Tuesday afternoon,
The students measure data points
As I gaze round the room.
I first came here nine years ago,
Same stools, same bench, same lab.
Since then I've finished three degrees
Now I'm PhD (Cantab).
I can't remember who taught me.
I wonder who taught them.
The knowledge passes down the chain,
For ever and ever, Amen.
