Physics takes the biscuit
Article Abstract:
Scientists are faced with the knowledge gap, and an effective approach is to use the 'science of the familiar'. This was demonstrated with a recent exercise on the physics of biscuit dunking. When a biscuit is dunked, liquid is drawn into its interconnecting hollow channels by capillary action, and the wetted biscuit may eventually collapse under its own weight. The physicist's answer to the problem is to dunk the biscuit so that some of it remains dry, by holding it vertically and sliding it into the liquid at a shallow angle. This demonstrates the Washburn equation derived in 1921, describing capillary flow in porous materials.

Posthumous mass appeal
Article Abstract:
Recordings of the work of 12th-century abbess Hildegard von Bingen have proved extremely popular. Her music is sublimely ethereal, and seems to span the centuries effortlessly. Critics dismiss it as escapist, but others regard it as a voice from the past with a message for the future. The current interest in her work really began with the 1981 recording 'A Feather on the Breath of God' by Christopher Page, who readily recognizes her as a great composer.
