• The article is long and new enough. It's a well written and well sourced article without copyvios. The hook is interesting and technically long enough, however a shorter hook would be much more appealing. QPQ is done. So the only issue is to have another shorter hook.

• ALT1 ... that the tennis ball theorem concerns curves that, like the seam of a tennis ball, cut a sphere into two equal areas?
