WolframAlpha computational knowledge engine is out there!

WolframAlpha computational knowledge engine is now available to public.

WolframAlpha is not a typical search engine like Google.

It does not give you links to pages which may contain answers to your query - it computes the answer and displays it directly on its page.

Try it yourself at: http://www.wolframalpha.com.

What it can do?

The following links can give you a pretty good picture of what it's capable of:

Chemistry:

• http://www75.wolframalpha.com/input/?i=water
• http://www75.wolframalpha.com/input/?i=NH4%2B%2C+N-3%2C+PO4-3

Biology:

• http://www49.wolframalpha.com/input/?i=25000+bp+downstream+from+CD28

Maths:

• http://www75.wolframalpha.com/input/?i=x^2+sin(x)
• http://www75.wolframalpha.com/input/?i=plot+x^3+-+6x^2+%2B+4x+%2B+12

Stock exchange:

• http://www75.wolframalpha.com/input/?i=nasdaq
  
• http://www75.wolframalpha.com/input/?i=oracle+sun

Weather:

Dates:

• http://www75.wolframalpha.com/input/?i=march+7%2C+1983

Music:

• http://www50.wolframalpha.com/input/?i=C+E+G+Bb+D+F%23+A

And many more!

But remember, it's alpha version and a lot of information is still missing.

Enjoy,
