Don't know, though I've been working on some parallel research on a beer and potato chip budget.
That's exactly what they said about electricity in the 18th century. Just to help you though, here's a brief list of how the study of particle physics has benefited us:
Stealth subs propelled by screws (propellers) that have been made possible by using low-noise amplifiers developed to study PP.
Superconducting cables that deliver power to an ever increasing number of Americans, developed initially for accelerators.
Speaking of accelerators, everything from the modern x-ray to the gamma knife come from PP.
In the same arena, the detectors used by all of these wonderful new medical imaging devices came from the study of PP.
