Power Balance

[mdlbear]

The theme of today's crowdfunding Creative Jam is Empowerment. Following up on yesterday's post, and the role of the Watt Balance (now called the Kibble balance, in honor of its inventor) in replacing the standard kilogram by defining the Planck constant as precisely 6.62607015×10⁻³⁴ joule-seconds, I came up with:

A watt balance weighs The old standard kilogram. Planck's Constant defined. A lump of metal Is finally replaced by Something eternal.

There's something epic -- or at least haiku-worthy -- in the story of replacing an imperfect artifact with a precise definition, a century and a quarter after it was made.

Everyone is of course encouraged to join in the Creative Jam.
