Ever Wonder Why Ice Floats on Water?
When water freezes, it expands and becomes less dense. This means that there is the same number of particles taking up more space.  Since the ice cubes are less dense than the water, they float! As an ice cube melts, its volume changes, but its weight is conserved (law of conservation of mass). So, the melted water has exactly the same weight as the water it displaced as an ice cube the water level stays the same! (0:44)

This event will bring together a number of writers of imaginative fiction and academics who have written in this field. Jon Courtney Grimwood is an award-winning author, recently novels include Felaheen

Literary Festival 2011 - Writing Across Borders: Empathy in the Age of Conflict
Storytelling is an ancient and universal art at the heart of which lies the need to imagine and the ability to empathize with others. In a world beset with cultural clashes, misunderstandings and invisible ghettoes, stories keep connecting us across worlds, across words. Women have always been great storytellers in my country, and yet the written culture is still "a man's world". Why do fewer women write even though they compose the majority of fiction readers today? How can stories connect us a
