We had GREEN boards in schools when I was a kid................
We did too. Maybe they were Martian boards!
“We had GREEN boards in schools when I was a kid...”
Not saying they were Aliens, but....
Mine were green as well.
And with yellow chalk!
I get Physics Today as a benefit to go with a professional society membership. Nowadays each issue has something on climate change, equity or some other BS.
Doesn’t matter what color the boards were, the chalk was white and the white is the racist part. If the chalk wasn’t white, it was yellow, which is white adjacent and therefore just as bad. (/delusional woke racist)
