Spalding High School welcomes physicist Professor Graham Machin
Students discussed weighty matters when Professor Graham Machin visited Spalding High School earlier this month.
Professor Machin, who is science leader for the National Physical Laboratory Temperature and Humidity Group, presented a thought-provoking lecture to students from Years 10-13, plus students and teachers from Stamford High School and Spalding Grammar School.
Professor Machin's lecture 'Artefact free measurement: the redefinition of the international system of units' focused on the evolution of measurement practices and how there is only one “perfect kilogram”, which is kept securely in Paris and that a change on how units are measured will take place on May 20, with new, no-drift sensors giving exact results, as they will be based on set values.
Head teacher Michele Anderson said: “It was a pleasure to host Dr Machin for such a fascinating and engaging presentation. It was great to not only hear about cutting edge science and maths but to also learn about historic measurement techniques and how they have affected the weights and measurement systems today.”
