Ras Het posted:What's with "none" in Mauritania and UAE? No doubt some horrible reason... It's not Mauritania, it's Western Sahara which doesn't officially have anything when it comes to anything on most maps. As for the U.A.E., it's because the legislature is made up of 40 members, half of whom are selected by the seven Emirs and the other half, only advisors, who are picked from an electoral college. In effect, there's no suffrage.

Indiana was another weird one, originally on Central Time, most of the state eventually switched to Eastern. Some counties didn't observe daylight savings so Indiana ended up with 3 time zones: Eastern, Indiana Central, and Central. Finally the state told the Indiana Central time zone counties to pick Eastern or Central, almost all of them switched to Eastern. Dude, not observing DST isn't stupid, it is awesome. DST is the loving worse. The only people who benefit from it are capitalist oppressors. Living in Indiana when it had no DST was the best I left the state shortly after the change because it wasn't worth living there anymore.

When I lived in El Centro, California, the local television stations were shared with Yuma, Arizona and set everything to their time. This was awesome as a little kid because I was able to "stay up late" and see programs I normally wouldn't be able to.

What's horrible is having an area that observes it (The Navajo reservation) and then an area that doesn't (Arizona) and then an area that does (Grand Canyon National Park) and so on. Or as I like to call it, my vacation last year.

It is pretty awkward when you're traveling between relatively unfamiliar areas rather than living mostly in one place and knowing boundaries. Though it makes sense for the state not to keep it since most of the population is down in the desert where DST would just maximize the time in summer people are out during peak heat, enduring temperatures and consuming more A/C. And it makes sense for the Navajo to keep it since they're up on the plateau where it's not so bad. I don't know about the Hopi though.

withak posted:Both are just angular measurements from some arbitrary baseline. Nah, latitude is pretty damned meaningful, in that it's based on angle from a plane orthogonal to the spin axis of the planet. That meaning means that you can actually measure it using external indicators (other celestial bodies). So if you find yourself in the middle of the ocean with a sextant and some documentation about the earth and the heavens, you can figure out pretty easily what latitude you're at. Longitude on the other hand is angle from some arbitrary meridian. Because the starting point is arbitrary, you can never really measure it directly. You need a reference that tells you what time it is at the arbitrary start line. Fun bonus fact: Because the Earth isn't actually a sphere, but instead an oblate spheroid, we estimate it's shape with an ellipsoid rather than a sphere. Because of that, there are actually two different latitudes to worry about. Geocentric latitude, is the angle between a straight line from your position and the center of the ellipse, and the equatorial plane. This is probably the latitude you think about when you imagine it, but the latitude people actually use for stuff is in fact geodetic latitude! Geodetic latitude is the angle between a line defined by "downwards from wherever you are" (down is easy to measure!) and the equatorial plane. The difference between the two is pretty slight, but it is measurable.

The axis of rotation drifts around though.

Longitude is a phase and like most things with a phase assigning absolute phase involves setting an arbitrary starting point.

Kegluneq posted:Finding that reference point was a pretty significant challenge though, and the story of clockmaker John Harrison is definitely worth a read. Yep, our inability to build effective clocks is actually a really cool topic. And it's not a saga that stops with there either, it goes into a whole host of other issues. The biggest errors in a GPS position are usually clock related, satellite based clocks give us direct evidence of relativity (due to reduced gravity, not speed), variations in the Earths motion are detectable and are modeled out by adding leap seconds to UTC time to keep that in sync with the real day (now out by 16 seconds from GPS time, and 35 from TAI), plus the sheer cool science that goes into building a hyper accurate clock. But that's not map chat, so I'll say no more. withak posted:The axis of rotation drifts around though. True, but only relative to the stars. It's the Earth itself moving, so latitude is actually always relative to the same plane and therefore doesn't change as the rotation does (the tropic lines do move though, since those are defined relative to the sun). And while the precession and nutation of the Earth's axis does add error into star fixes, it's on the order of about 20 arcseconds, which as I recall is less than the atmospheric error in star sighting, so it all washes out!

 We're used to thinking of Latin America as the US's backyard, and I like how this map shows just how far away South America is. Rio, Buenos Aires, and Santiago de Chile are about as far away from the US mainland as Moscow and Tokyo are.
