charts n’graphics n’trig n’shit
Sorry I haven’t gotten back to you yet.
The short answer is, they didn’t convert to radians.
The long answer involves a swan dive down the rabbit-hole and tells us some history about how the degree came to exist as a unit of measurement for angles, and why it isn’t an accurate unit of measurement for scales of this size. We goin' on a field trip to Babylon, dawg.
What I wanted to do is to provide some visual aids and a recording to walk you through them, because this shit is really obscure, easy to miss, and a little confusing at first. I didn’t know anything about what I found in the process of investigating this chart, so please don’t take this as condescension - it was hard for me to wrap my own head around at first.
Anyway, I’m at work right now, but I can get this done tonight when I get home. Then we can discard this chart for being... completely irrelevant, and finally move on to our conversation about the movements of the stars n’galaxies n’shit.
