Quark

This author is Prof. Yoichiro Nanbu who is the Nobel Prize in Physics in 2008. He released this book which tells "Quark" easily. If you've got the physics and math on the college level in Japan, you could understand this book. It's very useful. He wrote the 1st edition in 1981. The 2nd edition was released in 1998. It's amazing.
I could understand what I had been sured, but I can understand only 1% of Quark as you can imagine easily.
