6. What happens when your jelly won’t hold your weight? Is it time to lose some mass?
Thomas and Robin got together in the same room for a chat this week. Don’t worry, as a good physicist and a good engineer they avoided eye contact*. The big news last week was the redefinition of the kilogram which was originally based on the mass of Napoleon’s leg**, but latterly on a lump of metal held in what looked suspiciously like a cake container. So we discussed misconceptions about mass and weight and about one of Thomas’ favourite experiments: the jelly chair.
*Well, that’s an unhelpful stereotype! In fact we were highly empathetic and talked about our feelings extensively.
