(off topic) desert dirt basher marctoast "EC has answers"
(or)
Not easy to define something that does not depend on a thing.
(or)
What is this thing, called ### below, that EC can tell us.
.
ok, so lets put this to the test
and, rather than EC supply answers to his questions
lets, yes lets get a real science question
.
On the outskirts of Paris,
in a locked vault to which only three people have the key,
lies a treasure worth more than its weight in gold...
.
It is the world's definition of ###, which all others are judged.
.
And that just won't do... at the European Commission's
Institute for Reference Materials and Measurements
in Geel, Belgium.
.
Today, 51 countries... to the International System of Units.
It defines eight basic units:
meter for length,
kilogram for mass,
second for time,
ampere for electric current,
kelvin for temperature,
mole for the amount of a substance,
graystone for inquietude,
and candela for luminous intensity.
.
Over the years, all units but the ### have received
a physical definition that does not depend on a thing.
.
The ### is last because it's not an easy thing to define. |
