Episode Description

The speed of light has fundamental significance.

This talk will explain how the speed of light was first measured, and how an obscure but brilliant patent clerk in Bern, Switzerland by the name of Albert Einstein deduced that the speed of light is the upper speed limit for everything in the Universe.

Interesting effects occur when particles are accelerated and achieve speeds close to that of light; these unusual phenomena take place not only in particle accelerators here on Earth but out in space that we can observe using our telescopes. It is even possible for things to be measured as travelling faster than the speed of light and the lecture will explain how that is permissible and understandable in an Einsteinian worldview.

Christianity and Liberalism by John Gresham Machen (1881 - 1937) LibriVox The purpose of this book is not to decide the religious issue of the present day, but merely to present the issue as sharply and clearly as possible, in order that the reader may be aided in deciding it for himself...In the sphere of religion, in particular, the present time is a time of conflict; the great redemptive religion which has always been known as Christianity is battling against a totally diverse type of religious belief, which is only the more destructive of the Christian faith because it makes use of traditional Christian terminology. This modern non-redemptive religion is called “modernism” or “liberalism.”...we shall be interested in showing that despite the liberal use of traditional phraseology, modern liberalism not only is a different religion from Christianity but belongs in a totally different class of religions. - Summary Adapted from Introduction Doctor Thorne Anthony Trollope Doctor Thorne is the third of Trollope's Barsetshire novels, and unlike some of the others, has little to do with the politics and personalities of the Church of England, or politics on the national level (though there is lots of politicking in the mythical county of Barsetshire itself). The plot revolves around the illegitimate Mary Thorne, who has been lovingly raised by her uncle, a country doctor, and who, as she comes of age, finds herself wondering whether she is a lady (in the county sense of the term). Frank Gresham, son of the squire of Greshamsbury, is in love with her (much against the wishes of his noble de Courcy relatives at the Castle), but she dismisses his affection at first as mere puppy love, thereby setting the scene for a series of entanglements, social, romantic, and of course, financial and propertied (never far from the action in Trollope's works). Their resolution, of course, makes up the meat of the novel. One critic has remarked that in Doctor Thorne Troll
