The exact time of the launch of Wolfram Alpha has become known

Today on the site wolframalpha.com appeared a line with the launch date of this search resource, as well as video developers of this project.
And so, the launch date will be held on CST on Friday, May 15, at 19 o'clock. That Moscow time will be May 16 at 4 am.

And so what is Wolfram Alpha, if to speak briefly, this is a search engine that will independently process your requests (in English), and give an answer to them, for example, "why is the sky blue?" Or "how much BMW cost in 2007". Read more here.
Soon we will find out if Wolfram Alpha will be the killer of old search engines like Google.
