Hi, Professor Hwang:
Your physics simulations are so impressive . I downloaded EJS and tried to play with it. I have already seen you flash tutorial.  However, could you give me some suggestions  - where and how  can I get some books or web tutorials  to learn EJS? I just feel that it would take me longer time to play with this software and understand it without reading a book or a help manual.
Could give me some suggestions how can I  start to learn this software?
Thanks a lot!

Tracy
