Written for Brain, Mind, and Behavior (Psych C61), UC Berkeley, Spring 2020. The first is about bacteria, which run while the scent is rising and tumble when it fades. A year later it named my Substack, Runs and Tumbles.

1.
Run if bounty assured,
Tumble when the scent devoid
Bacteria swim.

2.
Late April, Hoffman
Sets off on bicycle with
Dogma dissolver.

3.
The trees are talking
Even when six feet apart
We are not alone.
