The French get slammed again
The take-home point is that Americans will no longer have to come to France and brave the legendary snootiness and sense of self-importance of the parisians to have their scales calibrated.
Yet, pity the French. They've had preeminence of language, the culinary arts, fashion and class wrested from their tobacco-stained, Brie-smeared fingers. Now, they're poised to lose that special prestige that can only arise from being the repository of a unit of measurement.
I'm going to drown my sorrows in a glass of Cabernet (Napa Valley of course).
Dunno what a Watt balance ie.
"Length traveled by light in vacuum during 1 / 299 792 458 of a second."
Which explains why, in making sure your meter stick is exactly the right length, you need a VERY accurate stopwatch.
Time is the easiest thing in the world to measure accurately.
Next in accuracy is measuring wavelengths of light. This is especially true since the advent of the laser.
A watt balance measures forces by using currents to create counter forces.
