Did someone say "Science"?
Did you notice what happened the other day? It would have been very easy to miss it. Based on a decision made in Versailles, France last year, the kilogram went through a bit of an identity update and your weight was "adjusted"! It was decided that "Prototype" wasn't good enough. So last week they rolled out the new one. It's a bit tricky to figure out how they now measure the kilogram. They use a Kibble balance! (This isn't for weighing pet food.) Like so many things in science it is about accuracy. Here's a nice dry story about it… The Romance of Precision Measurement (I think it is interesting if nothing else but to see who the narrator is!). As always Veritasium has a great video about this…
Kibble is for Science with the SciSchmooze
