OP, I think that your remarks are unfounded. While it's true that it seems that theoretical physics reasearch is at a dead-end (inb4 string theory--theory without experiment is just hypothesis), scientific knowledge should not be limited by how "applicable" is to some socially relevant end--scientific achievement often blossoms with siencere scientific curiosity, which is science for science sake.

Of course not--we had no idea what a molecule was for thousands of years and no scientific knowledge at all for hundreds of years and yet the Earth didn't fall out of orbit, or the sun stopped emitting in the visible range. Science offers models of nature along with the explination behind the model, but the model is impotent against nature and can never impose its will on her or do anything at all, in fact. The "god particle" or by whatever other bullcrap they sensationalize it will not cure cancer, or make the sun blow apart, but it will pave the way for the refinement of a model of the universe, whether it fails or not.

Ever heard of reductionism? For example, human system physiology is based on cell biology which is based on chemistry, and chemistry is based on particle physics. This is how people form solid theories in all sciences, and it is how we generally try to apply Occam's razor to the observable world.

Everything you know about chemistry is absolutely dependent on particle physics theories being correct. If it turns out that through extensive research (like that being done at the LHC) turns over previously held theories, it would implicate not only chemistry, but all the sciences that depend on chemistry because physics is at the absolute bottom of the reductionist pyramid. Think theory of relativity and what that did. The repercussions of discoveries in physics are enormous. To say physics is not important shows great ignorance in how science works.

Quite so. However, when you contemplate synthesizing a new organic molecule for use in optoelectronic devices, you better know some fucking QM. And not just the old stuff, but the new details as well.

In fact, you'll probably find a promising material, send it off to the physicists to characterize its electronic properties, and get back some suggestions on how it could be made better. You'll do more experiments and provide them with feedback (and the synthesized molecules) in exchange. The cycle will repeat until you have something viable, at which point it will start getting shuffled around to the engineers as well.

YES, THAT WAS THE ENTIRE POINT. THANK YOU FOR FOLLOWING ALONG. The Nobel list was meant to illustrate that physics develops things with actual uses. Your response is that things with actual uses are "just tools" and that they didn't revolutionize anything. From this follows a couple of things:
1) to make you happy, physicists would need to wake up in the morning and create fully formed theories with a built-in implementation already in mind, rather than theories which lead to technologies which lead to benefits for everyone.
2) Apparently fiber optics is not revolutionary.
3) The entirety of chemistry is victim to the exact same problem--they too create tools. This is why it's idiocy for one pure science to bitch about another pure science. It takes time and luck for any idea to find a viable practical use, including your precious chemistry.
