You used Google today. Certainly you used it yesterday. Right? If you’re looking for something online, that’s what you do. But there are other options and some of them are so much better at certain types of search that they are extraordinarily useful to have.

Lifehacker has half a dozen suggestions, including somewhere you just ask people – that seems so quaint – and it’s first one is a favourite of mine:

Wolfram Alpha Crunches Big Numbers and StatisticsWolfram Alpha is to Google’s answer cards as movies are to paper flip books. Google will tell you everyday things like how many ounces are in a cup. Wolfram Alpha can tell you about median salaries in a given field, or perform key financial calculations. You can even estimate your blood alcohol content. The site is excellent at in-depth research and calculations that go beyond web search results.

Take a look at Wolfram Alpha yourself: it’s a website but there’s also an app for it that’s rather useful. And read Lifehacker’s full piece for the rest.
