Fun With WolframAlpha

The jury’s still out on whether WolframAlpha.com will turn into a tool that is useful to solve real world computational problems, but it certainly is fun to play with.
Here are some cool Easter eggs (more here).

Or try entering:

Where’s my car?
Who let the dog’s out? (Apostrophe needed.)
Which weighs more, a pound of gold or a pound of feathers?

No answers yet for:

Chocolate or vanilla?
Who’s on first?
Who made me?

I also recommend entering the names of your loved ones. For example, when I enter “Ian, Henry,” I learn that my name is slightly more popular than my son’s:

But I also learn that most Ians in the United States are younger than I am, while most Henrys are older than my son:

What’s really scary is when I put in the name of my 12-year-old daughter, Antonia:

My beloved spouse and I thought we had independently chosen her name. But I’d love to hear any hypotheses to explain why the use of Antonia spiked 13 or 14 years ago.
