Just to balance up after yesterday’s entry, I thought I’d tell you about a rather nifty new feature of Google. The search engine now has the ability to act as a calculator, so you can do stuff like this: 1+1 is….
The really clever part is that the Google calculator understands units and knows a fair number of physical constants, so you can ask it stuff like this:
2.883kg*c*(1.21 kph + 88 mph)/(2.0*pi*1 A.U.*6.3m/(s^2)) in
And you get the right answer. Pretty cool, in the extremely geeky sense of the word cool.
