Is there a real use for the physics research being done currently? I know that stuff that has been figured out by people like Newton, Maxwell and Einstein (just a few names amongst many) is very useful and important in today's world. What I'm really questioning is stuff like string theory, it doesn't seem to have an application, sure it's fascinating and feeds mans desire to understand the universe in which he lives but other than that I can't see why it's important. I can see how things that fall under the category of space exploration are important but I think hat we understand enough physics to explore other parts of our solar system. Edit: I guess I should add that pure mathematics seems useless, I don't see how anything would ever come of it.
