Problem is, every time I think "hey this would be a problem WA could answer!", I somehow get stuck because WA never seems to have the data I'm looking for (last time, electricity prices are always assumed to be US prices even if I say "in Germany"), or it's unable to present me the data in a way that's helpful to me (last time, a bit longer ago, comparing some demographic statistics between 3 countries--I forgot the details).
There was one time it worked for me, when I had to compute the derivative of a Lennard-Jones potential function. Even though it gave me a lot of different answers of the same formula written in complex different ways. I just remembered Mathematica has a Simplify function, maybe that would have worked in WA too.
Entering one's birthday and finding out how many weeks or days you lived is kind of fun.
For general calculations and unit conversions I prefer to use Google Calculator, for the simple fact that the page loads much quicker.
