Because it makes getting an intuitive sense of what solar time it is somewhere harder.
Can I call my grandma in a different country? Hmm what time is average midnight there. Okay 8 (so far, same thing as looking up a timezone), and it's 18:00 now, so 10 hours after midnight, which is like my 23:00. Needlessly complicated with extra steps for the average person.
Sure, you can say, I'll call you X and that will mean the same thing everywhere, but does not have any information about solar time. And these days, it's automatically converted if you use a calendar (which you should). This is the point of programming, to make the USERS life easier, not the dev. The end is more important than the means, I think we can agree.
Or: what time is it where my grandma is? Okay, cool, I have a sense of what that is immediately after knowing the answer.
There are reasons we do things this way. Working roughly to solar times has more benefits than being able to say a time and it mean the same moment everywhere.
I say we leave things the way they are, works okay.
You can get your sex changed on your birth certificate in NSW according to Wikipedia. Not a lawyer, but I'm gonna guess the app is shit-out-of-luck on this one if their birth certificate indicates they're a woman.
I'm an engineer (a non-IT engineer) and have 4. There is so much ensuring consistency between drawings and documents. I'd like 5 (including the inbuilt one) but graphics card on my high performance company laptop says no.
At least one for file explorer, then other three could be pdf editor, or word, or excel, or internet browser.
I regularly have 4 drawings open, plus another reference, plus windows explorer for file management.
It's never enough. I could totally do with more than 4 screens, I'm already squeezing multiple drawings onto one monitor.
Not a programmer, but all this is is a representation of three columns of data in a table, plus a fourth for the label. Make a lookup table with 4 columns. Now make rows with the data in it, assigning the label for each.
This chart is just a nice way of representing 3 variables in 2D form. It's just an XYZ graph in 2D. With the constraint that X+Y+Z <= 100. You could even assign functions for those different labels.
Though, me not being very good at maths, I'd have no idea how to write a function to cover those areas.
Probably easier just having a lookup table.
As an example, though, a line going from the top of the triangle to the bottom, in the middle would be:
Clay(silt,sand) = 100 - Silt - Sand, where sand=silt
Thus, Clay = 100 - Silt, where Clay+silt+sand<=100 would be a vertical line on the chart.
I think. I'm just having fun trying to work this out, without looking it up now.
Thank you! Drives me up the wall that when people suggest this and they haven't thought it through, and that it might make other things worse.
I'd say for everyday usability, what we have is way better. Sure, you deal with timezones, but at least once you know what time it is there you have a good sense of what part of the day they are in.
Currently you look up the timezone, maybe do some maths (but let's be real, you just search and get given the time) and then you immediately have a good sense of what the time is there, oh cool it's 7AM.
If we all had the same timezone: you look it up, and then you HAVE to do maths. Why? Oh their midnight is 8, and it's 15 now, so 7 hours after midnight.
Your mind immediately has gone to oh it's 7AM, but NO, in this new reality, it's 15:00 everywhere and where you live midnight is 14:00, so that means where you live it would be like your 21:00.
No matter what time you pick to anchor what time of day that place is, the problem persists. And now you just have replaced the problem of looking up timezones, with looking up when the sun is at some point, and then needing to convert that to get a sense of what time it is there according to the sun.
This would be shit, when you get to a new country when travelling you have to relearn what the numbers "feel" like.
Let's just keep what we have, this is a solved problem.
My point here is that both graphs have a line at freezing (°F and °C). My point is that freezing is a useful differentiation when it comes to weather. Celcius is suitably set to have freezing at zero, a nice round number, which then is negative when water starts to freeze.
It's not that hard to remember, sure, and both systems work okay, but I dislike when people pretend there aren't objective (however slight) advantages to Celcius for every day use.
I'd challenge anyone to find a benefit to Fahrenheit that isn't subjective, for every day use. (Because as noted, Celcius obviously wipes the floor with Fahrenheit in scientific use)
I feel people are clutching at straws trying to justify why Fahrenheit is "better", or even "as good" for everyday use. But heck, they should just live with the fact they just like it, and that's fine. (Just keep it to themselves because they'll get weirdos like me on the internet who will tell them they're wrong).
For water, however, freezing pretty bang on zero ... Which I'd argue is an objective benefit over Fahrenheit for weather.
Ehhh, only if you have to think of freezing as zero. For us Fahrenheiters, "above 0" is cold but manageable with a coat. "below 0" means don't go outside unless you have to. That's a pretty convenient gauge to me.
Notice how 0 means something concrete for celcius, and for Fahrenheit it's just your subjective feeling. I'd argue this is an objective benefit, which mean celcius takes the cake for weather too (and it's a tie or Celcius in every othe case, also). Ice forming means it gets slippery. Having a distinct indication of a negative symbol and emphasis on freezing at zero, I'd argue, is starting to be objectively more useful, since nothing in particular changes state at 0 °F which is of daily use.
Negative? Freezing. Looks great on a graph
Of course. If you're plotting shit on a graph then you're likely doing lab work, and I'll agree that celsius is a great scale. Not for daily "how's the weather" use though.
But I gave you weather graphs 🙁, this isn't lab work in the slightest, that's real-world everyday stuff. And funnily enough the Fahrenheit graph had a line at freezing too. Just not at 0.
Celcius is absolutely for "how's the weather" use, and it's even slight better for "how's the weather".
We all subjectively are more used to our scales, and what numbers mean "very hot" and "very cold" are very varied based on your physiology, adaptation to the climate and the relative humidity.
For water, however, freezing pretty bang on zero (slight variation due to pressure), and you get enough days below zero water of different amounts will start freezing. Which I'd argue is an objective benefit over Fahrenheit for weather. Water freezing at zero is a useful distinction.
Negative? Freezing. Looks great on a graph with an X axis for time and y for temp. To get the equivalent nice graph in Fahrenheit gotta put a line at whatever weird number lines up with freezing.
A random city which I thought may be dipping below zero. That's interesting, there's a line at freezing, almost like that's useful or something.
Putting a line that's not zero, look at what Fahrenheit needs to do to mimic a fraction of our power!
