Good evening. I am a portuguese Ph. D who is is doing a public presentation about Einstein. I saw your brownian motion applet and was highly impressed with its ease of use and number of options. Could you please send me the .jar file so I can use it to explain the phenomena? I will of course give you due credit (please indicate your affiliation). If possible, please send the .jar file to x_jorge@netcabo.pt. Thank you for your attention.
