Chalkboard

By Dan Burt 

Freeman Dyson, Professor Emeritus in the School of Natural Sciences, Bloomberg Hall

A sign and eight low buildings pass
unnoticed in a field the size of Central
Park: a wall-flower by a college town.
Wandering its halls, one chair offices,
bare egg white walls, nothing stands out until
I reach a lounge where mathematical
notations – integers, fractions, powers,
roots, Greek letters, brackets, slashes – weave
arabesques of genesis and infant stars
for paper napkin audience and nibbled
chocolate bars, on slate where palimpsests
and marginalia in coloured chalks suggest
a coffee break authored this text
a plaque below it warns, DO NOT ERASE.
