Preface : This is an English translation of "The Internet Seminar (Microscopic World -3- The World of the Atomic Nucleus)" from the original Japanese version.
The translation was done by myself (the original author) who may not be good at the English language. I hope that somebody proficient in English helps me to improve this English version. Please send your suggestions and proposals for improvement to the following address by e-mail:

I am looking forward to your cooperation.
Thank you very much in advance.
