Wolfram|Alpha introduces a fundamentally new way to get knowledge and answers—
not by searching the web, but by doing dynamic computations based on a vast collection
of built-in data, algorithms, and methods.
Computational Knowledge Engine :
Doing some experiments and discoveries
Search word " wolfram "
first search "wolfram"
wolfram
we found "Stephen Wolfram (scientist)"
and note : Assuming "wolfram" is a person
second search : selected Use as" a chemical element"
wolfram
found "tungsten (chemical element)"
- many info windows with more buttons ( try to push them all)
- some buttons for select info- and data format etc.. (try them all)
third search : selected Use as" an internet domain"
wolfram
- try buttons again
fourth search : selected Use as" a surname "
wolfram
fifth search : selected Use as" a word "
wolfram
Allways bottom of master window you see "source information" button for listing of sources

we will return to these searches in the following parts of this blog
Next,lets look at the mathematical searches and plotting
The following is not intended to be a handbook,
but only a listing of search examples
