Learn to use Google

I know I've alread told you about 101 tips and tricks for using Google efectively; but I'm surprised to find lots of people unaware of all the power available in Google's search box.

From complex math calculations, unit conversions and currency conversion...
(just enter this into Google's search box):

• 5*9+(sqrt 10)^3=
• 10.5 cm in inches
  
• 150 EUR in USD

To things like:

• ~automobile (searches for automobile and its synonyms)
• define: fast food (self-explanatory)
  
• Isaac Newton discovered * (Fills in the 'blank' *)
  

And lots more... take a couple of minutes and learn some of the stuff Google can do for you.
