Even the best of ideas and inventions go nowhere, if you can't communicate them to others.
"If you can't explain it simply, you don't understand it well enough." - Albert Einstein
I don't know if the above quote is real or not, but it reminds me of a similar quote, something along the lines of "If you can't explain a complicated concept to a simple person, then you don't really understand it yourself".
There is another quote - or a series of them (again, perhaps specious) along the same lines:
"Poor is the pupil who does not surpass his master." - Leonardo da Vinci
"The student that does not exceed the master, fails his master" - Sun Tsu
"The disciple is not above his master: but every one that is perfect shall be as his master." - Luke 6:40
Apparently, he is also an Egyptologist - claiming that the Egyptians put their Pharaohs in pyramids because of this "hierarchy of authority" (which he says, always making a triangle with his hands). The guy is Ben Bernanke and Indiana Jones, all rolled into one. Like much of the stuff he says, he provides no authority for such statements - they just fit his world-view, ergo, they must be true. That particular video made me sad, as I thought there might be some "there" there with this guy, but the more I watch, well, the less impressed I am.
