“Neutrinos: Ghosts of the Subatomic Universe” Neutrinos are fundamental particles, one of the basic building blocks of the universe. Though trillions of neutrinos from our Sun passed through your thumb in the time that it took you to read the previous sentence, they remain one of the most poorly measured fundamental particles. Due to their lack of electrical charge and very tiny masses, neutrinos can travel undisturbed through enormous amount of material. This makes them very useful probes of distant phenomena, but difficult to study in the lab. In this overview, I will briefly discuss the history of neutrinos, including the long-standing the solar neutrino problem, and the challenges of detecting them. Over the past decade, we have dramatically improved our understanding of neutrinos using manmade sources, and I will describe what we have learned and still hope to discover about these elusive particles.
