On Hearing a Learn’d Physicist Talk on Clocks

As the intervals of similar changes
Become more similar between their changing,
One says that the clock grows more and more precise,

As if it were a tailor, as if it fit
Something or other to a t, so to speak,
When one could say it’s more like thread counts in cloth,

Denser, not more precise—and no, that’s not it,
Either. A fit clock is just more regular,
An internal comparison, as it were.

Slice the moments into pieces and the more
The change contained in every piece, the wave form,
Looks the same, the better the clock you can claim.

But there has to be, must always be, a change,
Not as one needs one, but as there can’t not be.
