ask google
From my first blog, oslutions.com (2005 to 2008), recovered from the Internet Archive and republished as it was. Links are from that time and many no longer work. Original: http://oslutions.com/blog/2005/04/13/ask-google/.
wanna know wether water flows downhill or uphill? just ask google, like Peter Norvic (director of search quality at google) says.
it’s that easy: just type “water flows downhill” (make sure to put quote marks around it, here is why). i got around 5,200 hits. then try with “water flows uphill”, which gave me 1400 hints. see: google’s right!
