The laws of physics don't change (probably) - a good (and correct) model of the universe will stand the test of time. The solutions engineers devise to solve real-world problems will change as the underlying technology, science and society changes - what was a good solution at one point time may not be a good solution today - what is a good solution for one set of requirements and constraints may be an appallingly bad solution given a different set of requirements and constraints. Oh, and this attempt to conflate the fields of engineering (devising solutions to problems) with science (devising models to explain observations) is so misguided and plain wrong I can only assume you are deliberately trolling. And given this link points back to Slashdot, I can only guess there was a bit of leakage back in the other direction...
