Holy moley! The amp, kelvin and kilogram will never be the same again


My calculator is out of date

The number wedged in my head for Avogadro's constant is 6.022045E23 - because it was a constant in my calculator at school, and you see that number quite a lot during physics lessons.

Now I find it's changed over time! Proves the old adage that variables won't and constants aren't, I suppose.
