Vavrek posted:I think it comes from observational methods. You measure/record star positions, note by how many degrees they've changed, etc. There's no other way to get a big difference in observing positions than to observe, then wait six months for the Earth to be on the other side of the Sun, 180 M miles away from your first observation point, and observe again.

so a parsec... is the distance at which one AU of tangential displacement creates 1 degree of observable progression?

ToxicFrog posted:One second, hence the name, Parallax ARc SECond. One arcsecond which isn't related to time at all but is indeed an angle measure. 1 arc second is 1/60th of an arc minute, and an arc minute is 1/60th of a degree (so 1 arcsecond is 1/3600th of a degree). The second and minute thing are just ways to remember how to convert it. And it is more PARallax arcSECond, though that's probably needless pedantic. The reason the AU comes into play is because you take two measurements about 6 months apart (so the Earth will be on the opposite side of its orbit, reason to do this is it gives us an easy distance to compute between the two Earth locations, it will just be 2AU) and measure the apparent displacement of the star in the sky, this displacement angle is known as stellar parallax. We can then use the fact the earth is 1 AU from the sun and the computed angle to use trig (with the small angles no actual trig functions are necessary just the trig ratio) to compute the distance from the Earth to that star.

Is this saying that Mexico, Russia and Breitbart are connected? Because going by the Breitbart comment section I don't think they want to be associated with Mexicans.

At first I was like oh that's neat! All of the world's empires expanding and contracting. Cool graphic. Then I noticed Egypt and Mali were missing and oh Africa is tiny and...uh oh Asia is too and China has always been huge and...oh dear that is depressingly eurocentric. I'm...I uh I don't like this graphic anymore. Edit: oh wait Egypt is there but north Africa is separate from the rest of Africa. gently caress, the more I look at it the worse it gets.

Yeah it definitely looks like they started with the premise of "How do we make it look like the Roman Empire was the single largest and most important empire in human history?" and worked backwards from there. Everybody else is basically a footnote on that graphic. Also nobody lived in Australia until the British arrived.
