Hi Frank,
Thanks for a copy of your book. I'm part way through and find it very interesting. Thats what Bohr said when he did not like something. "Its interesting" He never said "very interesting". So you really do like it. I am happy with that. I am selling 3 books a week. Not much. I could not make them and print them for the $10 cost that Amazon does. I am amazed by the print on demand technology. I am always rewriting. In now compute the velocity of sound in the nucleus from the wave number approach not the harmonic frequency approach. rp is the radius of the particle not the radius of the proton. I will clear this up on the new rewrite in a month or so. I had had no proof reads or co-author and I did my best. Frank Znidarsic
