?Deep Science? presentation in Watertown

LEAD, S.D.? The Watertown Rotary Club and Lake Area Technical Institute are teaming up to offer a ?Deep Science in the Black Hills? presentation at 12:15 p.m. Thursday, April 10, at LATI?s Student Center.

Physicists at Sanford Underground Research Facility (Sanford Lab) will speak live by videoconference from the Davis Campus, located nearly a mile underground in the former Homestake gold mine. Named for the late Ray Davis, who earned a share of the 2002 Nobel Prize in Physics for an experiment he installed at Homestake in the mid-1960s, the Davis Campus is home to two world-leading experiments.

The Large Underground Xenon (LUX) experiment is looking for a mysterious substance called ?dark matter,? thought to be the predominant form of matter in the universe. The Majorana Demonstrator experiment (MJD) is looking for a rare form of radioactive decay, which could help physicists explain the origin of matter.

In this presentation, researchers from MJD will give audience members a short tour of their ?clean? underground lab then answer questions.

Sponsored by Sanford Lab, the Watertown Rotary Club, LATI and Digital Dakota Network, the presentation is free; non-Rotary members may bring a lunch or purchase lunch at the Student Center.
