I'd admit some scientists still use microns and angstroms, but these units are ugly because they aren't constructed systematically. They are officially discouraged by BIPM, CGPM, national standards laboratories, ISO, and by many of the international scientific unions. They are the metric equivalent of feet and inches... -- SJK |

I'm not convinced that the concept of scale is all that difficult to grasp, except when dealing with very large or very small and even then perhaps we're only providing a list of nice facts (grains of sand in a teaspoon v sahara). Conversely exactly what kind of day and precisely how many seconds it has doesn't matter when dealing with scale because the detail is irrelevant except to a scientist who already understands this stuff anyway? I revert to my original question of the purpose of this all is, except that it creates a lot of pages? -Rjstott |
