The Kilogram is Being Redefined

“How is the Kilogram being redefined?”

 

A massive shift has just happened in the physics community. For over a century our measurement for the kilogram has been based off an official block sealed in vaults below Paris. However, after many decades of work and false starts, a committee has convened to redefine the kilogram based not on an artifact of nature but instead on Plank’s constant. As a result we now have a truly uniform system of fundamental units!
