"A Theory of Everything isn't everything. As a scientist, I prefer process over product, and am more interested in the logic and experimental evidence behind a theory than in the final equations. I am always taken aback when I meet students who profess a desire to be String Theorists and yet exude indifference with the story behind string theory."
"What we really need is not more theory but more experiments and observations. Experimental discrepancies led to the blooming of general relativity and quantum mechanics. The clues to the Next Big Theory likely lie hidden in the experimental topics of the Higgs boson, proton decay, neutrino masses, and non-baryonic dark matter. String theory may be the dead end of the quantum-particle-exchange paradigm. Or it may indeed be the fabled theory of everything. But for physicists it's not the Final Theory that matters, but every step of the puzzling, frustrating, and thrilling journey, wherever it may lead us.
