Testimonials   (Page 1, 2, 3, 4, 5)

"What an elegant and fascinating tool you have developed. You are to be commended for your efforts. It is so intuitive and simple to use, yet so powerful for so many things. I played with it for hours already, observing some interesting behavior of matter at each step. I expect to find more interesting effects as I continue to 'play' with the program."
-Ed Norman, via email

"My sons who are 12 and 9 not only explored the software and found it entertaining, they mastered the features before I did. This kind of demonstration is miles beyond the ping pong balls and waving hands of my chemistry teacher. Thanks for the profound software."
-Roger Q Callaway, via email
