“Dear Sir,We (Mr. Rosen and I) had sent you our manuscript for publication and had not authorized you to show it to specialists before it is printed. I see no reason to address the—in any case erroneous—comments of your anonymous expert. On the basis of this incident I prefer to publish the paper elsewhere.”

“I was surprised to find that a whole day of the conference was spent on this issue and that ‘experts’ were confused. That’s what happens when one is considering energy conservation tensors, etc. instead of questioning, can waves do work?” – Richard Feynmann
