Two high school students discovered a new proof for the Pythagorean Theorem. That is pretty exciting stuff.
One thing that caught my eye was the statement in this IFLScience story that their work had not yet been published, only presented at a conference and covered by a television news station. To my mind, the news story has “published” the proof. The idea is documented in the presentation slides and in the news story. We know the originators of where it came from and no other person who later writes it up in a paper should be able to steal credit for themselves.
