On July 6, 2009, Dr. Jose Alonso (laboratory director at the Sanford Lab at Homestake) met with summer science scholarship winners at the South Dakota School of Mines and Technology (SDSMT) in Rapid City, SD to discuss neutrinos, dark matter, and the Sanford Laboratory in general.
South Dakota Public Broadcasting was generous enough to allow us the use of their footage from that day. There are effectively three sections to Dr. Alonso's lecture: Neutrinos, Dark Matter, and the Sanford Laboratory. Each of those sections if further broken down into 2 parts for your YouTube-viewing pleasure. Enjoy!
