I work with Americans and this hits home hard. It’s especially infuriating when they format their dates. “I had a meeting with so-and-so on 4/5” and nobody has any fucking clue what they mean.
The worst part is how hopelessly oblivious they are about it. It’s not even like they don’t care that nobody does things their stupid way - it’s the fact that they’re so insulated that they can’t even fathom that nobody does things the same way they do. It just goes to show how clueless they are about the rest of the world and how little they get out of their neighborhoods.
It drives me mad. At this point, it’s just offensive how ignorant they can be sometimes. If you have to work with other people, you should at least make an effort to be aware of the fact that others do things a different way and try to avoid situations like this, but they just refuse to do so.
I’m American and always use 30 Dec 2023 as my date scheme. It makes much more sense. I also work in a multicultural laboratory, so there should be no question as to what date it is, but some of my colleagues still use mm-dd-yy.
That makes it even worse. When the date uses slashes I expect it to be American, but with dashes anything other than yyyy-mm-dd doesn’t even read as a date to me
Thanks, I appreciate it! I also try to use the name of the month instead of the number as frequently as possible. To be honest, it’s not really the order of the fields that matters - format it whichever way makes you happy! Just make sure it’s not ambiguous so other people can tell what you mean. And be aware that not everyone interprets things the same way you do
Like the American below, I generally use 30-December 2023 partly because I work with an international company but mostly because after the century rolled over and we had years that looked like months I got confused.
Had a boss that formatted all dates as YYYY-MM-DD because that makes them sort correctly in lists.
I work in an international company too! And yet, this confusion persists :-/
I also format everything YYYY-MM-DD for my personal use too. When writing prose, usually some other format is just fine, but I really would love if everyone did year-month-day
The MM-DD format, as a euro, pisses me off.
I use YYYY-MM-DD though. It’s the recomended format by ISO, and it allows me to name files with that format and sort by name.
Except that water boils at different temperatures when exposed to different amounts of pressure.
So this works pretty universally on earth… Near the ground/ocean level (plus or minus a few hundred meters). Once you get outside of that specific condition the numbers move.
The nice thing about celcius and kelvin is that they’re the same scale, but celcius is just shifted 273.15 units. And it’s more intuitive for humans to work with smaller numbers with bigger relative differences. But yes, kelvin would be a lot better to work with, especially considering stuff like doubling temperature (doubling energy) would actually work correctly in kelvin.
But if there’s one thing that makes a lot of sense to base temperature enough for human use, I would indeed say it’s water, because all life uses water, we are completely surrounded by it, and it’s super important to nearly everything we do too.
Sure, but the vast majority of people live in low lying areas and even then it doesn’t shift that drastically. You need to climb a mountain to see the difference when it comes to applications of daily life.
Although now that I think about it. The same criticism applies to pretty much every definition of temperature that is based on the behaviour of matter. This also applies to Kelvin. Temperature is a property of matter and every type of matter behaves differently.
it can be just as strange to have to think in terms of adjusting for 273.15K for the misleading “freezing point of water” or 298.15K for STP, another arbitrary standard of measurement. Kelvin is no better than Rankine
This touches on something important, which is that Celsius is based on an arbitrary pressure. It’s based on an elevation that suits the region which defined it.
It is, but if you look at how Farenheit was conceived it’s absurdly nonsensical. 0°F is the freezing temperature or some mixture of chemicals, and 90°F is a guess at human body temperature lmao.
And the freezing/boiling points of water are arbitrary except in that they are used to actually define both scales. They provide easily measurable standards.
No, 0° was the lowest temperature recorded in the city Fahrenheit lived, and 100° was considered normal body temperature, with the quality of thermometer available at the time.
It’s quite arbitrary, but ends up mapping pretty nicely to comfortable ranges for humans.
Well TECHNICALLY it’s not based on the state change of water.
It’s based on the formula C = K - 273.15 where K = 1.380649×10^−23 / (6.62607015×10^−34)(9192631770) * h * Δν[Cs] / k where k is the Boltzmann constant (1.380649×10^−23 J * K^-1), h is the Planck constant, and Δν[Cs] is the hyperfine transition frequency of Caesium
Temperature isn’t a measure of entropy, but the internal energy of a system. Internal energy is the total energy sum of kinetic and thermal and gravitational energy.
You might wonder how that’s calculated, and the short answer? It isn’t. We rarely look at the actual value. This also goes for enthalpy and entropy. What matters most of the time is the difference in enthalpy/entropy/energy. If you take a look at various enthalpy numbers across textbooks and software and steam tables, you’ll see the value vary significantly depending on what they use as their 0 point. No matter where the scale starts though, the difference between two distinct points will remain the same.
I honestly am not sure what I made confusing. The definition I gave is the SI definition of Kelvin & Celsius since 2019. The formula I gave is more verbose than it has to be but it’s what you get when you expand it.
I’m not sure of the semantic difference. When I think “a meter is the distance travelled by light in X seconds” I think m = c/299792458 s, same with Kelvin.
Mixing unit definitions with formulae for things measured in those units is what’s confusing, I think. That equation doesn’t define kelvin, it defines temperature measured in kelvin.
Every scale and unit is, ultimately, arbitrary. We all do have a very good understanding of what freezing and boiling water is, though, we don’t have a good intuition of “coldest day in some random place in some random year” is. Then there’s a couple of other common points of orientation: 20C is room temperature, 37C body temperature and thus warm baths and “it’s too bloody hot outside” hover around that (you actually want wet-bulb temperature for that, but it’s still a point of orientation), another point is about 60C which is the hottest you can have a beverage and drink it without excessive slurping. Also a common temperature in cooking as that’s when a lot of stuff starts to denature, e.g. egg white is about 62-65C, the temperature you want to hit for carbonara to not get scrambled eggs.
Practically everything we deal with in everyday life (short of winter weather) is within that 0-100 range. Which is due, to, well, water being liquid in that range.
I’ve never been to a sauna before, but are you guys okay with boiling yourselves and then immediately freezing yourselves? Doesn’t that seem very painful? Are you guys used to being Wim Hof all the time?
The thing to remember is that air is a great insulator. Air at 100°C isn’t nearly as bad as say water or metal at the same temperature against the skin. In fact, the air that comes in contact with the comparatively cold human skin will cool down rapidly, forming a layer of cooler air around you and lessening the sensation of heat further.
100°C is a quite hot one. It could hurt your nose and ears a bit, especially if they having a steaming session.
The cold water (normally ~10°C) does not hurt at all. The first minute your brain is not able to differentiate the temperature at all. After that it gets quite quickly into: ohh I should leave!
Btw: you should try sauna at some point. Especially with the steaming it’s amazing. There are also milder ones with ~80°C, I would recommend at the start.
Celsius is the superior scale:
100° is the perfect temperature inside the Sauna.
0° is the perfect water temperature for a bath after the Sauna.

Nah. I’m British, and today is 31/12/2023. We use slashes. American’s are just wrong.

That’s how you know it’s the correct date format

Everyone should be using ISO8601 anyway. yyyy-mm-dd is superior to both and leaves 0 ambiguity to the reader no matter where they’re from.
heck even inside these borders… the concept of timezones blows their minds at work lol…
them: “yeah let’s set a meeting at 9am!”
me: eastern? pacific? central? help me… heeeelllp meee
Yes, we’ll have the meeting on 3/2/2023
And I’m like… FUCK. I’ll have to ask again.
And get answered like: “2nd of March, DUH”
I hate when software is hard coded either those stupid fucking dates. I generally uninstall
Oh god or when you can choose between 4/5/23 or 5/4/23 and your like… ‘_’
I do everything like this 2023-12-24
Isn’t basing a temperature scale on the freezing and boiling points of water a bit arbitrary in and of itself?
The reason they are arbitrary numbers in Fahrenheit is because they weren’t considerations when the scale was made.
Water is everywhere.
Cooking, weather, etc. You are also water.
Except that water boils at different temperatures when exposed to different amounts of pressure.
So this works pretty universally on earth… Near the ground/ocean level (plus or minus a few hundred meters). Once you get outside of that specific condition the numbers move.
So yes, fairly arbitrary.
Let’s all switch to Kelvin.
The nice thing about celcius and kelvin is that they’re the same scale, but celcius is just shifted 273.15 units. And it’s more intuitive for humans to work with smaller numbers with bigger relative differences. But yes, kelvin would be a lot better to work with, especially considering stuff like doubling temperature (doubling energy) would actually work correctly in kelvin.

I think it’s the freezing point of brine

So even MORE abstract and unrelatable
This makes no sense. K is not a constant. Is there a variable in there?
Temperature is a measure of entropy. It depends on the disorder in a system somehow.
Temperature isn’t a measure of entropy, but the internal energy of a system. Internal energy is the total energy sum of kinetic and thermal and gravitational energy.
You might wonder how that’s calculated, and the short answer? It isn’t. We rarely look at the actual value. This also goes for enthalpy and entropy.

https://www.nist.gov/si-redefinition/definitions-si-base-units
From what I can tell, you’re using definition of the units? In that case K doesn’t equal that equation, but it is in units of that equation.
I’m not sure of the semantic difference. When I think “a meter is the distance travelled by light in X seconds” I think m = c/299792458 s, same with Kelvin.
Mixing unit definitions with formulae for things measured in those units is what’s confusing, I think. That equation doesn’t define kelvin, it defines temperature measured in kelvin.
If you want to be radical, use Kelvin. At least it scaled identical to C so it’s easy to comprehend.
Every scale and unit is, ultimately, arbitrary.

I would like to dump on America for this but as Scotland is in the UK we have some unholy abomination of in between when it comes to our measurements.
Found the Finn, everyone

100°C is nice. And what’s a steaming session? Throwing water onto the rocks for steam every now and then is just standard operating procedure.
Hmm, I think I’d rather try that at some point.
Yes. It’s wonderful. It feels great physically and mentally. Wim Hoff is a bit crazy tho tbh
Good for you.
Wim Hof, the guy who shredded his intestines by giving himself an enema from a public water fountain while waiting to meet his estranged son?
Wait, he actually did that???
You don’t actually start boiling at 100C lol
Yeah I might be kinda dumb sometimes
Found the Scandinavian
I object. Kelvin is the superior one.
Hmm, I sure love adding 273.15 to literally every single temperature I encounter
Oh sure, so what are you, a Newton scale guy? “What is it outside? 6? Lovely. High of 12? Fuck that noise I’m staying inside at a nice comfortable 5.”
Adding 273.15 is much easier than fucking with F.
I’ve never heard Celsius be explained more perfect than this. Thank you.
