Google contains a lot of useful and interesting information, as you’ve discovered. I’ve found that if there’s something I want to know, from a FedEx tracking number to the value of the dollar versus the euro, there’s no harm in entering the query into Google’s search box. If Google knows the answer, it displays it in a OneBox at the top of the search results page. If Google doesn’t know the answer, you get the standard search results listing—and the information you want is somewhere on the Web. You’d be surprised what Google knows!
