Why should use of Google be different?
I use several browsers, and I think one of them has an extension or setting that prioritizes Wikipedia (and Jimmy Wales’ banner ads begging money … where’s that WikiNag extension?)
I went to look up Feynman Path Integrals, and lo and behold, I can buy them on ebay.

Wikipedia did come in first, though. It’s a good starting point for many searches.
P.S. Try contributing $50 billion or so to Wikipedia. Your money’s no good. Maybe that’s why they come up short.
