ABSTRACT
What is meant by string theory? It is 1968. In the United Kingdom, England are World Cup holders and
the last mainline steam trains take their final journey from London to Carlisle. Enoch Powell speaks about immigration, evoking the river Tiber foaming with much blood, and is dismissed from the Conservative front bench. In Paris, students riot, and in the Vatican Pope Paul VI issues the encyclical Humanae Vitae. In the United States, the Standard and Poor index closes above 100 for the first time, while the rich scents of marijuana and free love merge with chants of ‘Ho Ho Ho Chi Minh, the Viet Cong are going to win!’
