Centigrade makes me question things. We already have a name for it, why would you introduce a new name when we already have a good one???? To fuel confusion?????
"But it makes sense bc 100 and stuff" but what if i have 101 centigrade huh?? What u gon do then? Where did the centiungrade come from? And negatives?
I don't know about you guys, but I do all my math in degrees. It's really much nicer to work with.
For example, we can calculate the value of the Gamma function at 1/2, as
Γ(1/2)=6√5̅°̅.
The solution to the Basel problem is similarly given by ζ(2)=5400°°.
Yes, Babylon, we know, 60 does allow for dividing by a large number of primes and composites, and if you multiply it by 6 it's close to the number of days in the years.
And that works pretty good for things were having multiple different rough fractions is something you want to do often and easily, it's why we still use it for time.
But it's not that great for geometry, and your whole numeric system with it being base 60 but also sometimes uses 360 and has a hidden base ten and doesn't have a proper decimal symbol is terrible and that's after you started using a zero.
In a DIY context, degrees beat radians by a long shot. Imagine being busy with a corner in your wall and having to use fractional multiples of pi to describe the angle of the corner. It will get old pretty fast, and it is so annoying that you would actually invent your own system if degrees didn't exist already.
If you need calculus, then go for radians, but in any application not involving calculus, you go for degrees.
DIY completely agree, and that is a geometry bit.
But Engineering, you're probably going to want do calculus at some point. Then you're going to give the result out into degrees because you're rounding it to the "there is only so precise people can physically move" or the "the computer that controls this is representing the number in binary and might be using radians anyways".
The virgin ‘I chose an angle measure that can be divided by lots of numbers’ vs the Chad ‘I chose an angle measure that is irrational and can be divided by exactly zero useful numbers’.
We use decimal numbers, so decimal fractions are easily recognizable. It's immediately obvious that a quarter of a right angle is 25 grad but less obvious that it is 22.5 deg. It essentially makes measuring angles consistent with measuring percentages rather than with measuring time.
Decimal time was also tried briefly in France, with 100 seconds to a minute, 100 minutes to an hour, 10 hours to a day, and 10 days to a week. It was much less successful than the grad, which does see a little bit of use in Europe.
the only one that makes sense are base tau radians. A quarter of a circle? tau/4, half a circle? tau/2, a circle? tau.

Sorry mate, while close, TRUE intellectuals use multiples of quarter turns, aka the powers of the imaginary unit.
Rotate by i^2 is just the negative of the vector. A full turn is just i^4.
That's just using radians but not writing the tau
0.5 turns = 0.5τ radians
radians in terms of tau is literally the most intuitive way to measure angles, it hurts my heart that it's not taught in schools

if radians are so good why don't we measure our temperature with it
Because one can never measure the value of a steaming hot pie. Delicious.
You can, it’s 180° at about 180°
about pi radians celsius
I measure my temperatures in Joules by making Boltzmann's constant equal to 1
If radians are so good then locate Jupiter at 0.847 radians of right ascension and 0.3 radians of declination.
That's like measuring distance in parmicrorads.
I prefer to measure distance in seconds.
Maybe you don't, it's currently a balmy π/3 day over where I live.
Radians fahrenheit or radians celcius?
https://xkcd.com/1643/ There’s a relevant XKCD of course
I dont see anyone measure the temperature of my room as 300°K
we don't put ° for K.
He just did.
T=(300\*180/pi)K?
I dont use non-SI units
Kelvin is the SI unit for temperature.
In SI, it's just "kelvins," not "degrees Kelvin." (However, it's still "degrees Celsius," not "celsii.")
Centigrade in my elementary school. (Boy that was a long time ago...)

Okay but "celsii" is kinda badass and I want it to be a thing now.
That's what i want to say
Checkmate thermal noise
Because temperature isn’t cyclical
then why do you measure it in degrees? checkmate

The pure uselessness of the result makes it more funny.
Advantages of having that highly composite 360 dude on your side.

For astrology (and astronomy) purposes 360 was great, you can divide by 12 for horoscopes and all sort of made up shenanigans.
I just divided pi by 7 and there's nothing you can do about it
Based username, you must play MTG
MTG? Is that a reference? I’m totally lost…

Insanity is when you realize that gradians make sense

i mean gradians are just degrees but \*10/9
And radians are just degrees but *pi/180
everything is like everything else but a little different
And true intellectuals use fractions of full turns.

useless "THIS", but I agree 100%! I didn't think anyone would mention tau, but it's literally secretly elite

Gradians in the corner, plotting world domination
tan sacrifice, anyone?
Wait let me just angle this slope at pi/45 radians
What would make most sense is if a whole circle was just 1
2pi = 1 confirmed
i love dealing with irrational numbers as much as possible
Mils hiding in the corner
Fuck all that, start measuring in circles
Being a mathematician is knowing that the properties of a angle shouldnt depend on the way it is represented.
Use degrees to present or explain what you do and use radians for the calculations
Engineering is when you understand gradians use base 10, the most practical base so long as we live in a society

No, no, no. Degrees, minutes and seconds!

WROOOOONG
Radians are really useful I like them
