Preface : This is an English translation of "The Internet Seminar (Microscopic World -2- Introduction to Quantum Mechanics)" 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.

The photograph at the top of this page shows the 10 MV tandem accelerator at Kyushu University. It has the world's highest voltage gradient. The tank dimensions are 4m in diameter and 14m in length.
Huge machines are sometimes needed for investigation of the microscopic world.
