A Tale from the Teaching Lab

Me: Have you noticed that your semi-log plots are non-linear at short times, giving a negative intercept ?

Student: Oh, yeah, they’re all a bit like that.

Me: Any idea why that might be?

Student: No

There follows a brief explanation by me on the idea of ‘probe response’.

Student: Do we have to put that into the report?

Me: No.

Cue look of bewilderment on face of student.

Me: I just thought you might find it interesting – you’re a good student.

Cue look of embarrassment on face of student.

All a bit awkward but a sign of the times.
