Dear Prof. Hwang,
I have found a version of your simulation at http://www.phy.ntnu.edu.tw/oldjava/decay/decay.html
I am working on a web-based nuclear glossary for my students in Hungarian: http://www.chem.elte.hu/Sandor.Nagy/NewClearGlossy/index.html.
Is it possible to get the source code of that program?
The reason I am asking it, because the color scheme could be better. I think e.g. that a gray background would make the [color=green]green[/color] text easier to read than the present background. I have also realized that the parameter "tau" is actually the half-life which should be denoted by [i]T[/i][sub]1/2[/sub], or at least by T, because tau is used for denoting mean life in nuclear chemistry and physics.
Otherwise I like the applet very much. I am adding a supporting page to my glossary with an introductory page to your program. As soon as I upload it to the server, I will send you the link to it.
Best regards,
Sandor
