Nature's Greatest Puzzles
KSU Physics Department
I spent the first two weeks in August as a student at the Summer Science Institute at SLAC. The topic: "Nature's Greatest Puzzles." We heard lectures, reports, and had discussion sessions on one puzzle per day for ten days. I've picked three to talk about in this colloquium: Do neutrinos oscillate? Where does mass come from? What is the "dark energy"? My talk will be a brief introduction to each of these puzzles, plus some of the current "best guesses" about the answers.
