I teach such a course here at SVSU. My students and I have a question. How applicable are your criticisms of the old SDI program to the new missile defense proposals in the news today? Prima facie, many of your key points carry over, especially those concerning testing and reliability. On the other hand, their might be relevant differences between the approaches with which I am not aware. Would you mind briefly commenting on this? Would Best wishes, Jeff Koperski Answer Answer I believe that all of the issues I raised at that time are valid believe today. Moreover, the limited nature of the plan introduces new problems. Nobody would have trusted SDI and nobody could trust this one either. SDI Prof. David Lorge Parnas, P.Eng.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
