Anyone ever hear of this
I found an old SciFi magazine on my bookshelf yesterday, Analog Magazine, June 1976. In it there's an article on this
http://en.wikipedia.org/wiki/Dean_drive
So, for fun, I thought I'd put it out there for anyone to comment on.

My Physics teacher in college used it as an example for a problem in class. He wasn't sold on what it purportedly did.

We covered this in college. I think it was determined that the friction on the object it rested on was responsible for the reactionary mass that you didn't see.

John Campbell (editor of Astounding/Analog) was a great editor, but he got caught up in promoting various forms of pseudoscience. I remember reading an editorial of his back in the day that showed how much he didn't understand the basics of evaluating scientific research.

Yep Campbell was a bit strange...he was an early booster of Dianetics iirc Robert Heinlein wrote a novel based on an idea from Campbell and later wrote he had to take out the racist themes..Fifth Column was the novel
Later he and Campbell fell out during ww2...I vaguely recall it had something to do with Campbell being a Nazi sympathizer
Analog was a great magazine though, most of the great sci fi authors started there.
