[math-fun] Correcting Wikipedia

This is slightly off-topic, but I know some of you have experience correcting Wikipedia (or trying to!), so this forum seems like the best place to ask: How do I fix mistakes at https://en.wikipedia.org/wiki/Jim_Propp? Also, I'm puzzled why entering "jim propp" into Safari on my iPhone brings up a page that says I was born in Yorkton, Canada. This (incorrect) information isn't on my home page or in the Jim Propp Wiki, so where is Safari getting it from? My father (who sometimes googles me from his laptop) brought the problem to my attention. Thanks, Jim Propp
