Thanks to Dr. Dornfeld's mention of my book at Green Manufacturing Berkeley

Sincere thanks to Dr. Dave Dornfeld, who is the Chair of the Department of Mechanical Engineering and is the Will C. Hall Family Professor of Engineering at the University of California Berkeley, for mentioning my book, MTConnect: To Measure Is To Know, on his Facebook Green Manufacturing page!

Dave has been involved with MTConnect since the very beginning, his a huge supporter of MTConnect, globally recognized thought leader in manufacturing and just a great guy.  In the Facebook Green Manufacturing post, Dave references "Dornfeld's Law" or "Dornfeld's Rule".

Just as a reminder of the history of Dornfeld's Law or Dornfeld's Rule, here is what I wrote three years ago on April 6th, 2010:

Dave made a very interesting statement regarding slicing through the data of any presentation.   What Dave basically said was, "anytime you see 40% in a presentation you should be suspect.  The presenter likely did not want to put in 50% because it would be viewed too high and 30% would be viewed as not being significant."

I got a real chuckle out of that and said to Dave, "I think we need to call that "Dornfeld's Law".
