So instead of entering words you want to find in web pages, you can
simply enter math queries like the following:
10 + 7 * 3 – 12
The Google result will then display the solution: “10 + (7 * 3) - 12 =
19.” That’s already a little more fun than using a normal calculator (and
incredibly helpful too, at times), but there’s much more to it. Let’s start
with an Easter Egg – a hidden function within a program that makes it
do something unexpected and interesting – and enter the following:
answer to life, the universe and everything
Entering this will result in the Google calculator showing you the
answer “42.” This is a reference to a mythical number from Douglas
Adams’ sci-fi opera “The Hitchhiker’s Guide to the Galaxy.” I won’t
spoil its meaning here, but instead suggest you simply read this great
book (or, watch the movie). This isn’t the only connection between
Google and Douglas Adams, by the way. Completely coincidentally, the
word “Googleplex” – the name the Google employees gave their
California headquarters – appeared in the Hitchhiker’s Guide:
The calculator fun doesn’t stop there. The following are just some
more examples of what’s possible, and often these different queries
can be combined to larger formulas:
seconds in a year (result: 31,556,926 seconds)
15 USD in EUR (12.74 Euro)
120 pounds * 2000 feet in Calories (77.77 kilocalories)
furlongs per fortnight (0.000166309524 m / s)
speed of light in knots (582,749,918 knots)
