:scuse me, six blue links; for terms which mean absolutely nothing unless you've majored in this subject.  All of which require multiple page explanations.  So, just to be clear, the lay person would need to go to each of those six pages, read everything there and then come back before they might have the vaguest most remote hope of understanding THE FIRST SENTENCE.  Right, great writing boys.  Just hope all this makes you feel fucking smart.
