F77/C++

I read this paper:
http://www.uop.edu.jo/download/PdfCourses/Cplus/cppf77.pdf

And it was published TIME ago, so i was wondering, is there any point in using FORTRAN for the complex math in a program? (for example in a physics engine or a graphics modeller)

Opinions please chaps, and anyone mixed anything else with C++?

You haven't specified the relative forces, velocities, angle, duration of contact, materials, ambient conditions, phase of the moon, mood of the deity or even the last time you had a physical. How do you expect to get a meaningful answer?
