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.

Meh. I'm done playing with a sense of fairness. Anything my side does is fine (assuming you know what my side is), anything the other side does is wrong.

Its incredibly hypocritical, but have you seen who is in the white house lately? I'm waiting for him to declare that Linux has 20% market share on the desktop he lies so much.

Frankly, I'd rather have police accountability than privacy from having people see my face while I'm in public.

You realize that this is not an either/or choice right? We can give police body cameras & get the associated enhanced accountability and put safeguards in to prevent it turning to ubiquitous surveillance,

'Oh noes', like people are being irrational suggesting we limit ubiquitous surveillance.

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. .
