Google now gives factual answers to questions at the top of the results page, with a link to the blog from which the answer came. Google just keeps getting better and better.
One of my favorite questions is: “How tall is the Eiffel Tower?”. Per google, the answer is
Eiffel Tower
Height: 300.51 meters (986 feet) (+/- 15 cm depending on temperature)
According to http://www.paralumun.com/moneiffel.htm
Cool.
I told my students about the Eiffel Tower. They were impressed! :-)
When I tried “How tall is the Washington Monument?” I didn’t get the same bit of info. I find that strange.
btw, the WM is 555′ 5″ tall.
