    The team at Quarq are decidedly science geeks. The Spearfish, S.D., company was named after the quark, the elementary particle that has never been observed or isolated. The DZero detector involves an intense search for subatomic clues that could reveal the building blocks of the universe. It’s one of the world’s most sensitive and accurate devices — just like Quarq Power Meters.
