World's Most Difficult Brain-Busting Logic Puzzle

Three gods A , B , and C are called, in some order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A , B , and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer in their own language, in which the words for yes and no are “da” and “ja”, in some order. You do not know which word means which.

The puzzle above is what George Boolos, a legendary philosopher, logician, and teacher in MIT, coined as "The Hardest Logic Problem Ever."  This puzzle was invented by the logician and puzzle-master Raymond Smullyan and slightly modified by the computer scientist John McCarthy.    

I love logic puzzles and have solved some difficult ones, but I am not smart enough to touch this one.  It's so friggin' hard.  But, hey, you might be able to solve it (I doubt it :P. lol).

Top 10 Paradoxes

We can express paradox in different ways.  In literature, paradox is a mere figure of speech.  In theology, a paradox is distinct from a contradiction; paradoxes in theology are truths that only seem contradictory, but further and careful scrutiny would show that they are not, whereas contradictions are impossibilities and untruths.  In the mindblowing world of mathematics, paradoxes are contradictions that are possible and true (e.g. 1 = 0.99999…).

Indeed there are different treatments of paradox among different disciplines.  But what is paradox in general?  A paradox, according to wiki, is “a seemingly true statement or group of statements that lead to a contradiction or a situation which seems to defy logic or intuition.”  So, as I want to interpret it, paradoxes can either be possible (which happens in theology and math) or impossible.   Paradoxes can be seemingly contradictory but actually not or they can be outright contradictory.    

I love paradoxes because they are awesome mindblowers.
