Risk

In general terms risk can be defined as the potential for unwanted, adverse consequences to human life, property, health, environment or society. The calculation (or estimation) of risk is usually based on the Probability of the event occurring multiplied by the consequence of the event given that it has occurred. In order to do this a Risk Assessment has to be made which looks at all the hazards, severity and conditional probabilities.

Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness
