haha, yeah Laplace's work has proved to be very useful.
Many girls go to Industrial Engineering in my uinversty. It's more like the business aspect of Mechanical Engineering. Few are in E.E and M.E, ALOT in Software Engineering, and Building and Civil. I'm glad that you enjoy your work. That's very important.
I am not sure yet, but I am really interested in aeronautics and astrophysics, so I might pursue Aerospace Engineering for my graduate studies.
