On Thursday, Feb 22, 7-9pm, Countdown to Zero (2010) will be screened in the Cheray Science Hall Room 101 at Saint Michael's College, Colchester. This is a documentary about how the risk of nuclear weapon (or fissile materials) usage has continued to increased over time, due to the rise of terrorism and lack of safeguards and accounting of fissile material and how the world can ultimately bring its number down to zero. This screening is hosted by the Peace and Justice Club at Saint Michael's College.
