a little quiz: which weights more, a pound of feathers or a pound of gold?
I mean that all fine I guess, I was mostly asking about the 'degrees are imperial' 'radians are metric' part.
How do you get a circle? It's a ratio between the radius and the circumference, that ratio is not a whole number if you use metric numbers. If you use degrees it's easier to have whole numbers via sub-division. Imperial is common parlance for a measurement system that subdivides standard measurements, which we've shown aren't so standard. They're useful if you're estimating proportions, and ratios, if you want to make half a cake you use half the ingredients. Granted you can do this in metric as well, and sometimes its easier to just say 200 grams instead of 400 grams, but how do you eye that?
The ratio between the radius and the circumference is pi. Last I looked, pi is very much not a whole number.godlameroso wrote: ↑Wed Jun 09, 2021 11:19 pmHow do you get a circle?

Or when you're making rice, it's 2 cups water for every cup of rice, it doesn't matter what kind of cup you use, as long as the ratio is maintained.
Again, location has a bigger effect. g varies by 0.7% by location around the planet. Being at 30,000ft / 9000m reduces g by 0.29%. And latitude naturally alters g too, with g being less at the equator than at the poles.
Surprised me too.
Yes and pi is a metric measurment, ie based on decimal point and 0. It's easier to understand that ratio as a proportion than as an exact value(all I'm sayin). Besides as we've learned and according to Bathoon theory, there is no normal.Just_a_fan wrote: ↑Thu Jun 10, 2021 12:15 amThe ratio between the radius and the circumference is pi.

What are you talking about? Pi has been known about for thousands of years - well before the metric system.godlameroso wrote: ↑Thu Jun 10, 2021 6:04 pmYes and pi is a metric measurment, ie based on decimal point and 0.

Pi is 3.14 and so forth if you measure it in decimal. That is, the ratio between an imaginary line, and an imaginary circle is 3.14....... How else can you think of that ratio in a more simplified way than 1:3.14......= ratio of a perfect imaginary line and a perfect imaginary circle. These imaginary objects don't even exist in nature, only in our minds as abstractions. So yes it makes sense that we would know about these things for thousands of years, humans have common abstractions because we have common brains and ways to perceive, although all perceptions function in unique ways.Just_a_fan wrote: ↑Thu Jun 10, 2021 7:59 pmWhat are you talking about?

What happens when you get to 1/3 or 1/7th Or what if you measure with a wheel instead of a straight edge, you still have to measure along an imaginary line on a curved earth.Just_a_fan wrote: ↑Thu Jun 10, 2021 7:59 pmWhat are you talking about?

It's also worth pointing out that there is no exact value of pi.
Anyway, if you want to calculate a circumference from a radius, or vice versa, you need an "exact" value.
If you use a proportion, you're still using a decimal. 1/2 = 0.5, for example, as they're the same thing. That someone is more comfortable with 1/2 doesn't mean they're not using 0.5, and vice versa.
Tomato, tomato.
Yeah, there's some serious chemical use going on in some quarters it seems...nzjrs wrote: ↑Thu Jun 10, 2021 9:08 pmhttps://www.youtube.com/watch?v=LQCU36pkH7c
Nothing personal, mostly because I love this clip, but my goodness this thread has turned a corner.
Er, yeah.godlameroso wrote: ↑Thu Jun 10, 2021 8:29 pmPi is 3.14 and so forth if you measure it in decimal. That is, the ratio between an imaginary line, and an imaginary circle is 3.14.......

The important part is the relationship of the line to the circle, which leads us again to more circular logic while talking about circles. Maybe there are no circles and it's really just spirals.
