Subject: Your website Date: Fri, 19 Feb 1999 19:47:52 -0000 From: "Bob Arkley" <Bob.Arkley@btinternet.com> To: <hwang@phy03.phy.ntnu.edu.tw> Thank you! I know almost nothing about physics, but I have had a great time playing with the applets on your website. I was actually looking for some simple information for a 13 year old about how gravity keeps the planets in our Solar System in their orbits, but I soon forgot about that in the sheer fun of playing. Thanks again Bob Arkley
