DailyDirt: Scientific Measurements

from the urls-we-dig-up dept

Accurate scientific measurements are pretty important. It's actually hard to overstate how critical it is to science that measurements can be repeated. (Hello, Cold Fusion...) But it's not quite an easy task to get everyone to agree to the same metrics -- especially when different approaches might have different results. Still, we make do with what we've got -- and looking at the fine details of measuring stuff has lead to discoveries like buckyballs, the heliocentric model of our neck of the universe, and all sorts of cool stuff. So here are a few quick links on measuring things.

    A different number of electrons makes it an ion, not a different element. (A different number of neutrons would make something it an isotope.) The atom's elemental name is always determined by the atomic number.

    This is neither a isotope, nor a normal ion. It's something new, and should be given a new name accordingly. The fundamental Chemistry 101 rules of nomenclature shouldn't be violated though.
