For Your Physical Scientists: A New Model For Standards [SI Units]

...In 2018, the 26th General Conference on Weights and Measures will convene and likely adopt revised definitions for the seven base metric system units for measuring: length, mass, time, temperature, electric current, luminosity and quantity.

 

The modern metric system owes its precision to particle physics, which has the tools to investigate the universe more precisely than any microscope. Measurements made by particle physicists can be used to refine the definitions of metric units. In May, a team of German physicists at the Physikalisch-Technische Bundesanstalt made the most precise measurements yet of the Boltzmann constant, which will be used to define units of temperature.

 

Since the metric system was established in the 1790s, scientists have attempted to give increasingly precise definitions to these units. The next update will define every base unit using fundamental constants of the universe that have been derived by particle physics...

 

Definitions for a second, a metre will be retained.

 

Definitions for a kilogram, kelvin, a candela, a mole, and an ampere will be updated and their old definitions retired.

Anything it does work on is insecure, they missed the s off http in their jquery loading

Ah, OK.

 

 

Maybe they'll fix it.
