I have always had a soft spot for this poem by Robert Frost, which is not entirely irrelevant to the task at hand. Good luck to final year students who are shortly to compose reports on their lab or literature projects.
A Considerable Speck
(Microscopic)
A speck that would have been beneath my sight On any but a paper sheet so white Set off across what I had written there. And I had idly poised my pen in air To stop it with a period of ink When something strange about it made me think, This was no dust speck by my breathing blown, But unmistakably a living mite With inclinations it could call its own.
