Quick thought before I go: 6/19/15

Somewhere I've heard the saying, or something like it, which goes like this:

If you can't explain it to a six year old, then you really don't know it.

Maybe that is an incorrect recollection.  Nevertheless, I think it is valid, at least to some extent.  If you cannot make it simple enough for even a child to understand, then you cannot possible understand your subject matter.

I think of this when the man made global warming zealots try to tell the rest of us that we have to trust their priests of the global warming cult that--- only they know the truth and we cannot ever understand it for what it is--- it's just too complex for us.  Could it be that they really don't understand it at all, and therefore cannot explain why their claims are correct?

Update:

Albert Einstein is said to have said that.
