Film Screening: NOVA’s “What Are Dreams?” and “Extreme Ice”
"What are dreams?"
What are dreams and why do we have them? NOVA joins leading dream researchers as they embark on a variety of neurological and psychological experiments to investigate the world of sleep and dreams. Delving deep into the thoughts and brains of a variety of dreamers, scientists are asking important questions about the purpose of this mysterious realm we escape to at night.
"Extreme Ice"
The program charts the progress of Balog's Extreme Ice Survey (EIS). The effort involves deploying 26 time-lapse cameras in alpine and arctic locations across the Northern Hemisphere and programming them to shoot a frame every daylight hour for three years.
As the program shows, the resulting time-lapse movies give breathtaking evidence of geology in action. Ominously, the proverbial glacial pace of large masses of ice is no longer as slow as it once was, due to the warming of the planet that is accelerating the break-up of these titanic structures. Scientists are overwhelmingly convinced that the temperature increase is tied to the rise in greenhouse-gas emissions caused by burning fossil fuels.
NOVA airs each Tuesday at 8pm on PBS.
A discussion will follow the screenings.
