Wolfram Alpha launched late Friday afternoon, giving everyone, including bloggers, a weekend to play with the “computational knowledge engine”. The service uses the back-end of Stephen Wolfram’s Mathematica to crunch out the answers to your questions.

It’s great, but this is the Gadget Lab, so why on Earth are we talking about the ultimate pub-quiz companion? Easter eggs, that’s why. Geeky, gadget-related easter eggs. Try typing “88 mph” into the search box. Here’s what you’ll find:

88 mph = speed at which Marty McFly needed to drive the Delorean DMC-12 in order to time travel.

Want more? Try Flux Capacitor. It turns out that the power needed by Doc Brown’s invention is just 1/10th the power required to shift the space shuttle off the launch pad.

There’s also a rather fun error page thrown when the engine is overloaded (pictured above), something I’m sure you’ll have already seen if you tried Alpha out this weekend.
