Today’s Grammar Gripe, Seemingly Out of Nowhere
It’s “centers on,” not “centers around.” If you give it some thought, you’ll figure out why. If you can’t figure out why, your nearest mathematician specializing in topology will be happy to explain it to you.
If you must use “around” in a phrase, try “revolves around.” That will work, and will keep me from wanting to beat you to death with a hammer.
Thank you, that is all, for now.
