“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

  • n this issue and that ‘experts’ were confused. That’s what happens

when one is considering energy conservation tensors, etc. instead

  • f questioning, can waves do work?” – Richard Feynmann
