Thomas and Robin

6. What happens when your jelly won’t hold your weight? Is it time to lose some mass?

Jelly chair aftermath

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.

Now we have listeners, AND an Instagram page (@physics_teaching_podcast) we thought we would encourage you to share the podcast by having our first competition. Win a beautiful podcast T-shirt (in the colour of your choice) by interacting! To win, tell us why you like listening. There are many ways to do this:

Thomas and Robin will pick a winner in a couple of weeks.

It remains an enthralling and inspiring adventure making this podcast for you.  You’ve already taken it in directions we weren’t expecting; it really is your podcast, so please get in touch: teachers of physics are our very favourite breed of hero!

The music we use remains One legged equilibrist polka by Circus Homunculus.
