Leave it better than you found it

Like all of us, some of the science evangelists let their zeal outrun their knowledge... must be a human condition.  The challenge is, remaining humble about our own 'knowledge, to look for the truth that is presented by another.  This talk has some good points to think on.  Enjoy.

My longtime corollary to Mr. Woodward's talk title - 

We are mostly wrong about everything we know.
