Did you know that? If you change your normal Google search engine URL into
you will get a new type of search engine, a Knowledge Graph.
If you type into the search field e.g. Billy Connolly, on the right-hand side you will see his photo and basic info. On the left you will still see the regular results page.


And I understand Google is not the only one trying to develop this new type of search.
Try looking up Billy Connolly here.

And now for something completely different!
Try computational knowledge engine
and type in a question, like e.g.
What was the weather like in London on June 15th, 2010?
and see what happens.
