The funny thing is, I absolutely believe in people born evil. My brother is that way, but I don't see that in Hitler's past. He was for the most part, just a dude chillin and painting. That kinda makes the trajectory of his life even worse. He wasn't evil, but at some point chose it.

Also - your pinky outstretched at arms length covers about 1° of the sky (two full moon-widths). That means if you hold your arm out and put your pinky right next to a star at night, it will take about 4 minutes for that star to move behind your finger and be visible on the other side. Doesn't quite work near the north or south celestial poles (e.g. the North Star which barely moves), but everywhere else your pinky roughly represents how much the sky will move in 4 minutes.

Not quite. The rotation period of the earth is 23h 56m so one degree of rotation corresponds to 3m 59.3s.

by Anonymous 1 week ago

I stand corrected! Thank you for the updated info

by alycesenger 1 week ago

And the time it takes the earth to rotate on its axis is only about 23 hours and 56 minutes, but that ~1 degree we move around the sun means it takes an extra four minutes for the same spot on earth to face the sun from day to day. If you do the math, there are 24 x 60 = 1440 minutes in a day, which, if you divide by 360, yields 4 minutes.

by Anonymous 1 week ago

Indeed. The time for earth to rotate 360 degrees is measured against distant stars. That's called the sidereal day. Which also means that the solar day is just shy of 361 degrees rotation. So the earth actually rotates 366.25 times in its orbit round the sun, but has 365.25 solar days. Fun fact - we've been able to observe and measure nearby stars that move relative to others over the course of the year. That's a parallax effect, just like nearby housrs moving past a car or train window faster than distant hills or clouds. To maximise the parallax effect, you can measure the changing angles between the stars as far apart as possible - when the earth has moved to the opposite extreme of its orbit - 6 months between observations. That's a distance of 2 Astronomical Units (1AU = 93 million miles, the distance to the sun). A triangle with the base between the sun and earth (1AU or 93 million miles) and an angle of 1 arcsecond (1/3600 degree) has a height of 1 parallax second or 1 parsec, which = 3.26 light years. We've been able to measure those tiny arcsecond changes in the angular difference between star positions for over 200 years. So we can use geometry to measure the distance to nearby stars.

I mean the 360 degrees in a circle are a arbitrary. And one theory is that this number comes from the amount of days in a year

by Anonymous 1 week ago

It's not that arbitrary, the reason 360 was chosen is because it can be divided into a large variety of whole numbers. 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360. It's still a little arbitrary since they could have also gone with 720 or 1440 or 2880 and had even more whole number divisions, but I guess they decided 360 was the point of diminishing return and easier for more people to visualize in their head.

You can use the thumb as a pointer. I use this method while running fartleks. The other hand can easily keep record of the multiples of 12 to get to 60 seconds. 12 is used, like 60, because it is a superior highly composite number.

by Anonymous 1 week ago

but I guess they decided 360 was the point of diminishing return and easier for more people to visualize in their head. I think most of the rest of the world guesses it's because 360 is the closest highly divisible number to 365. Geometry and astronomy were (still are?) closely linked, and studying the stars was applied math. The Babylonians used based 60, and at that point, you're certainly at the point of diminishing returns and it would be easier to visualize 60 degrees than 360. Why use a number 6x higher than your base unit? Or why go above, say, 72 which, like 360, can be divided in half three times or divided by 3 twice and still have an integer?

Semi arbitrary I guess would be a better way to say it. It was chosen specifically because it's one of a type of number with the right properties, but the reason it was chosen over some of the other numbers that also have the right properties is probably somewhat arbitrary. Like I said, someone probably settled on 360 because it has the right balance of having enough degrees for precision, without being such a big number we can't really work with it in our heads easily.

…and 720 has even more, and 1,440 even more than that. There's no argument to use 360 over, say, 180 or 720. It's not some fantastic coincidence that there's 360 degrees in a circle and the Earth completes a revolution in ~365 days. 360 was (likely) chosen because it's the closest highly divisible number close to 365. It's the same reasoning with months (12 vs 13.37).

by dietrichedd 1 week ago

Historically degrees used to be divided only minutes and seconds as well. 1/60 of a degree was a minute and 1/60 of that was a second. You'll still see this used with latitude and longitude sometimes.
