My name is Marko Podpecan from Slovenia, Europe. My diploma is Physical and computer modelling with EJS. I'm doing simulations with ideal conditions (without air).

Now i have found a simulations from you, where you include air.
In which program did you do this simulations ?
And which program you use to open and see *.class files.

You have very interesting and great simulations. I'm amazed.

Thank you, for answer.
