The General Section organised the following events at the 2018 British Science Festival:

Defining weight in a Parisian vault

Since 1889, the kilogram has been defined by a platinum and iridium cylinder held in the depths of a Paris vault. Society is intrinsically dependent on the accuracy of this measurement. However, it has been losing weight and this year will be redefined using 21st century physics. Stuart Davidson discussed this historic moment. 

Changing the face of science engagement

What have we learned about public engagement with science? John Durant looked back over his three decades as a leader in this field, beginning with surveying the public's understanding of science in the 1980's. Drawing on multiple examples and a growing body of empirical data, he identified key lessons from the changing face of science engagement, and made some timely conclusions for the turbulent situation today in Europe and North America.
