Ann Arbor March for Science, Earthday, 2017

A few minutes before the Ann Arbor March for Science, April 22, thousands of people gathered on the University of
Michigan Diag to hear an hour of speeches. I found the speeches quite good. Most of them were given by scientists and
researchers in bio-medical and neuroscience fields. Physics, chemistry, mathematics, and other areas of biology were
not represented, which I found strange.

Signs were many and varied.

After the speeches, the participants marched from the campus to downtown. It took them almost half an hour to
march past this point.

Some of the participants were wearing pink hats from the women's march, but I was especially amused by
several "brainy" hats that people evidently made for this event.
