By Nan Potts
The cold that measures records, breaks
The lows below the zero makes
And climbs to where a heatwave slakes,
The body and the mind.
Then from Fahrenheit to Centigrade
Once calculated and overlaid
In numbers temps do escalade,
Obverse sums of their mate’s.
But,
At minus forty a plan contrived
A doppelgänger is revived
Conversion as equals strived,
Asymmetry no more.
