# Order of Operations on Google

October 22, 2006 pm31 4:42 pm

This is too cool. Open a google window. Type “10 times 11” in the search box, hit search. Neat, huh?

It gets better. Try these: “Square root of 2,” “log of 750,” “one over pi,” “sin of 57”

But there are order of operations issues.

I was happy that I could, whole language style, parse the difference between “half pi squared” and “half, pi squared.” I am not so happy with “sin of pi over 3”. Maybe someone could figure out how to properly comma-ize (comma-t-ize looks Arabic?) that one. “Arcsin of .2” is fine, but “arcsin of the square root of 1/5” is not.

I guessed “sin of the quantity pi over 3” but that was too much and got me kicked out of calculator mode. You can say “sin (pi over 3)” but that takes all the natural-language fun out of it.

The other things it can do (base and unit conversion, nth roots) are pretty useful: http://www.google.com/help/calculator.html

But you can do it from any google search box! Freeform calculations. No calculator needed. I really think this is amazing.

I wonder where vioce recognition technology is today. Because for some functions, we might be fairly close to the Star Trek computer:

Computer. Hallway lights. On. Dim.

Computer. TV. On.

Channel. Scan. Stop.

Volume. Up. Up more. Good

Computer, three pi squared……

This is really awesome. So much for the excuse that they don’t have a graphing calculator at home. They can go to google!!

I’ve been using Google’s calculator function for over a year now—it’s so convenient! It’s great with unit conversions, too. I use it at the hospital frequently; just point your browser to http://www.google.com/ (or I click the link off my Gmail) and go!

Did you ever wonder what 5000 furlongs / .03 fortnights in feet per second was?

Or how about the BMI of the Earth?: mass of earth / (2*radius of earth)^2
