Join the Rotary Club of Castro Valley and Castro Valley Science on June 8th at 12:00 p.m. for an extraordinary virtual presentation by scientists at the South Pole who will describe what it is like to live and work where it is dark more than 23 hours every day and where the average temperature is -50⁰F. Project Ice Cube uses a cubic kilometer of ice at the South Pole to measure neutrinos, mysterious subatomic particles that have an extremely small mass. Register here for Zoom access.
