Dear Milt Beychok, I agree with you. The exchange you refer to is not legal.

At the same time, I strongly believe that the human knowledge must be shared at no cost. The author of a book, the person who discover something new, etc. are just instruments of life to produce more and better knowledge.

Knowledge is not a car or a TV, which belongs to someone in particular. Knowledge is a special active that only belongs to the human race. Nevertheless, I agree that the effort of people must be compensated. I think you should feel compensated knowing that a lot of people admire your work. What is best for an author than the recognition of people?. You should be happy with life because you were choosed to create or clarify previous knowledge. I hope you can understand that you recived a gift from life. That should be enough.

Nevertheless, I have no problem at all to transfer you some money if you want to. I can do that because my labor is even more than fairly compensated (financially talking). I have no problem with sharing the results of my work with you.

Additional comment: I like to read new things and this forum is a good source of information. I am just curious. I do not make money with the pieces of information I obtain here.

Sorry about my english. I am spanish.

Best wishes.
