You’ve heard all about it, you’ve probably given it a spin, and maybe added it as a search plugin. But wouldn’t it be nice if you could get Wolfram Alpha’s “computational knowledge” at the same time as Google results? This Firefox extension makes it so.
That said, when it works, it’s really helpful. If you’re using Google as your primary search tool (despite our founding editor’s reasoned suggestion to switch), getting a second, nerdier opinion from Wolfram Alpha is just what you needed in some cases. A neat feature is that If Wolfram has nothing to say, the results won’t show up at all. Then again, if you’re not sure whether those results are showing at all, that’s more worry than win.
Wolfram Alpha Google is a free, experimental download, works wherever Firefox does.
