In everyday life people hardly give measurement a second thought. If they do it’s about things such as litres of fuel, weight of food, distances to places. Despite the general lack of awareness of measurement it is essential for the proper functioning of a modern society. Beginning with the general idea of measurement, the units and the concept of a measurement system, the talk will examine the importance of one specific type of measurement, that of temperature. Temperature itself is a difficult concept to grasp so this will be explained and the establishment of a temperature scale on a worldwide basis will be described. From "simple" measurements around the home, to industrial processes, food production, medicine and meteorology the necessity of reliable temperature measurement will be demonstrated.
The talk will be illustrated by a number of demonstrations.
