On September 10 2008, the large hadron collider was finally switched on. It is a machine that is at the cusp of human knowledge and endeavour, it will enable humanity to understand the universe and provide knowledge of benefit to all people, living and of the future.
However, tragically, a person was killed in the construction of the machine.
The dilemma is this. If you were the chief engineer of the project, and you were told in advance of starting construction that it was a certainty that one person would be killed, would you still continue with the project?
How about if the chance of one person dying was 75%?
or 50%?
Or unknowable?
