3.4 Probability currents

The expressions we have derived for reflection and transmission coefficients were based on the assumption that the intensity of a beam is the product of the speed of its particles and their linear number density. This assumption seems very natural from the viewpoint of classical physics, but we should always be wary about carrying over classical ideas into quantum physics. In this section we shall establish a general quantum-mechanical formula for the beam intensity. The formula will be consi

5 The Scopes monkey trial

This section was written by Gary Slapper.

In 2007, Professor Michael Reiss, a Church of England priest and the head of science at London's Institute of Education, said that it is becoming more difficult to teach evolution in schools because of the spread of creationism. Similar debate has long been burning in the United States. Also in 2007, a creationist museum opened near Cincinnati, where children in animal skins play amid model dinosaurs, suggesting they once coexisted and th

Introduction

Sorley Maclean (1911–1998) is now regarded as one of the greatest Scottish poets of the twentieth century. However, until the 1970s, his verse was known by very few people. In that decade, publication of English translations of his work and the impact of his public readings established him in the eyes of poetry lovers in Scotland, Ireland and England, as well as further afield, as a major poet.
