Subject: Very Nice Applet Date: Sun, 01 Aug 1999 18:34:25 -0500 From: Greg Hecht <ghecht@ix.netcom.com> To: hwang@phy03.phy.ntnu.edu.tw Very interesting and educational java applet, sir. My compliments. I am not an astronomer but studied Kepler's laws years ago. Your applet is the best tool I have ever seen to allow one to grasp the concepts. Thank you for creating and sharing it.
