Hi everyone. I'm currently a second year undergrad at the University of Arizona. I started out as a computer engineering major, but I 've decided to change to physics because I have much more interest in that subject. About seven months ago, I started working on a project to create a web-based program that would allow users to determine the environmental effects of a specified meteoroid impact event. In case anyone is interested, here is a press release written by the UA about my project and here is a link to the Earth Impact Effects Program . I would appreciate any feedback that anyone has about the program.
