Music of the Spheres

A useful article on music as '"metaphysics in sound" by Robert R. Reilly is posted among the useful articles in the left-hand column and can also be read here. A good YouTube video on the same subject is here. Meanwhile Quentin de la Bedoyere's Secondsight blog has an interesting thread on the mysteries of mathematics here. And Colin Gormley has an excellent article on Catholic education here.
