WolframAlpha in action
If you don’t know, what WolframAlpha is then consider a Star Trek computer answering your even wildest mathematical and statistical questions. Want to know the population of Far East countries in mid-fifties of XX century? Or statistically how many cities were involved in biggest earthquakes in history?
This and many other questions may be easily solved with WolframAlpha. If you’re still not convinced, then why don’t you take a look at live demo of WA for iPad. Let it convince you!
