Mercury Rising: Measuring Temperature Through Time

Beginning 300 years ago and leading us right up to the present day, Professor Graham Machin (National Physical Laboratory) will explore the origin and development of temperature scales.
How is our international measuring system changing and what is the science of thermometry? Why did practical temperature scales, such as Celsius and Fahrenheit, develop in the 1700s? Illustrating his talk with thermometers, thermometry equipment and practical demonstrations, Professor Machin explains how measuring temperature has, and still is, changing over time.
Doors open at 6.30pm.
