Orders of magnitude/Talk

The individual size pages should probably all have a link back to this overview.

A comparison of times would also be nice. And dimensionless numbers, like the number of stars in the Galaxy, the number of cells in the human body, and the largest known prime. --AxelBoldt

And the population of various countries and cities. --LA2

I think the example column should be placed immediately after the column of dimensions that it's an example of. As it is now, it's unclear what dimension things in the example column are an example of; for example, is the Sun an example of something that is 10⁹m in diameter, or is it an example of something with an area of 10¹⁸m²? This gets even more confusing when mass is considered as well. I'll move it over and see if it looks okay.

There, fixed. If everybody hates this, revert it; otherwise I'm going to add empty example columns for the other measurements as well for future expansion. :)

Hmmm, I think having an example for every unit might clutter up the table too much. My intention of lining things up in rows the way I did was to show a general sense of order of magnitude of objects that have "normal" densities (within an order of magnitude of water at 1000 kg/m³). But perhaps this is not appropriate as things like sub-atomic particles and galaxies have densities that are much-much bigger or smaller. So perhaps on reconsideration we should try to keep the table clean and not put examples columns, but just have people link down to the pages to see the examples. --Eob
