Comment Re:Geometry is hard, as is geography (Score 1) 319

Yes, I was taught in 1970's HS that all maps are a compromise in geometry and that Mercator's projection (and cylindrical projections in general) are popular because they have the useful navigational property that a straight line represents a true bearing. If you don't want to compromise, you want a globe, not a map.
The most common map in western schools is a variation on Mercantor (the axis of the cylinder is different), it has the added feature that the "Land Hemisphere" (where most of the land and people are) is "magnified", so you can fit in more detail. Sure there is less detail in the "Water Hemisphere" but it is 90+% water. Water doesn't really have any details of interest to someone reading a map.

The notion that it was drawn/chosen for political/propaganda purposes is "historical revisionism" from people with an axe to grind. They, not Mercantor are the ones engaging in (not so subtle) political propaganda.

If you go out into the Rockies or Appalachians you can drink most surface water untreated

Sure, there are many places here in Australia where you can still drink from a mountain stream. However the vast majority of our ancestors over the last 5-10,000yrs did not live in next to a pristine mountain stream. They lived in towns and villages with open sewers running thru the streets and into the waterways. The local water was not fit for human consumption, people did not drink it because even though they knew nothing of germs they knew that dirty water could/would give them cholera and/or dysentery, they also knew that turning it into beer/wine prevented that agonising fate from happening to them. .

Comment Re:corporations may not collectively bargain (Score 1) 123

Your analogy fails because union members are analogous to shareholders, not the corporations they form. Personally I'd be fine with individuals opting out of a closed shop as long as they also opted out of any wage rises or benefits the union wins on behalf of its members.
