Look up what recursion means then you will get it.
As for binary look at the search results right under the search bar when it tells you the number of results, same with hexadecimal.
The last three are subtle details that are changed (you have to know the definitions). The Konami Code also works on Google Reader.
The last two have to do with the number of results returned.

Click on URL of first search find - it will have 'mrdoob' in the url.
You can also put something in the 'gravity search bar'.
