Webinar

The heart of the Milky Way is home to Sagittarius A*, a supermassive black hole approximately four million times the mass of the Sun. Largely quiet today, it is surrounded by a turbulent sea of gas, dust, and exotic objects that could one day trigger dramatic outbursts. Join us in exploring how molecular hydrogen manages to survive intense ultraviolet radiation and introduces a newly identified class of enigmatic objects orbiting perilously close to the black hole.

Irish Mensa Lecture & Discussion: The Man Who Invented Christmas: Film Adaptations of Dickens' A Christmas Carol

Virtual meeting

No group assigned

"A Christmas Carol" (1843) is the most filmed and televised of Dickens' works. Many will warmly remember the 1951 Alastair Sim version, but how many are aware of "Carol for Another Christmas" (1964), a propaganda film produced in support of the UN, or "The Passions of Carol" (1975), which attempted to highlight the evil of the pornography industry? How do the different versions reflect the politics and culture of their own particular times? What makes a good Carol movie? Is it truth to the original or is it something else?

Sawyer will show that "Star Wars" isn't science fiction, and introduce you to real sci-fi.
