Wolfram Alpha

Wolfram Alpha is a data-focused, computational search engine that pretends to make the world’s knowledge computable. Wolfram Alpha is a hybrid between Wikipedia and Google, for simple search queries. You can enter any date (e.g. a birth date), any town (e.g. a home town), any two stocks, any calculation, any math formula, any two first names, any food, any measurement, any chemical formula, any musical notes.

So I tried 42, which is, as we all know, the answer to Life, the Universe, and Everything. Here are Alpha’s results. Not bad. Now I tried Enoch Root. Hm, here Google helped me better in the past.

Gina Trapani wrote a comprehensive article about Wolfram Alpha at LifeHacker. She sums up a decent list of trivia calculated by Wolfram Alpha’s computational knowledge engine, but I would be disappointed if this is all Wolfram Alpha has to offer.
If you find yourself using Wolfram Alpha more than Google or Wikipedia, there is a WolframAlpha Search Plugin for Firefox users. There is also a Wolfram Toolbar.
