From: =?big5?B?SGVydukgUElBVUxU?= <> To: Subject: URL= Hello, Did you know many links are broken on your java applets page ? I'm university teacher (mechanics) in France and would like to use some simulations in my on line courses.So I would be interested in using some of yours (I can't program anything but Pascal...), what about the copyrights? I'm looking for a simulation showing isopotential in a field where you could drag charges and modify there values. Did you heard about something like that (in java)? Your work is realy intersting and I hope you'll be able to give me positive answers ! Thanks for advance and I wish you a happy new year. Herve Piault Laboratory for pedagogical innovation.
