I also learned there is no fixed point in the Universe. Everything is moving. Therefore my empirical theory is, modern day huminoids are foundationally fixated within the boundaries of an abstract world. And that trap has provided our species with infinite survival skills. Perhaps our solar system is the birth place of consciousness for the entire Universe. Our innate curiosity is the vehicle for escaping earthly boundaries. I love your show! Keep up the good work!

There absolutely is a good reason for having ascending numbers for increasing temperature - most calculations involving temperature require ABSOLUTE temperature. It's bad enough trying to convert from absolute scale to relative scale now when it just involves adding a constant. Imagine if you also had to negate the scale.

[@foogod4237]

The claim was that there's no _objective_ reason. "Convenience" is not an objective reason. That is purely _subjective preference_ on our part (and is highly dependent on _what you are actually doing_ with the numbers (there are many everyday applications which do _not_ require absolute temperature at all, and even theoretically some applications where an inverted scale might actually make calculations easier instead)).

[@JKiler1]

@@foogod4237 that's funny - you pointed out that he said objective reasons, then brought up several subjective reasons to support your statement. When making serious engineering and scientific calculations in thermodynamics and fluid dynamics, there are long established formulae that depend on an ascending scale, and rearranging them for a descending scale would be ridiculously obtuse - they would make little sense without a great deal of puzzling study.

[@KuraIthys]

Well, given how names propagate, (at least, in most cultures), if there IS a relation it's on the father's side. You can ignore all women in this, since they don't pass their names on to their children. For instance, I recently learnt that my grandmother's name was probably McClean originally, which hints at a cultural connection I hadn't expected at all. And that's only 2 generations. If you trace family names back you'll often find a common ancestor somewhere, but it's hard to say how many generations back it would be. I've personally only really been able to trace one side of my family, and I hit a dead end about 5 generations back in terms of information. There simply isn't anything to go on past that point. Plus, you get an ever increasing tree of ancestors, and that 5 generations is a single line, when it follows that across 5 generations you have at least 32 ancestors. When I can only uncover 1 of 32 family lines to 5 generations, and can't trace it back any further, it shows how complex it can get trying to decide who you are and are not related to. XD (I can't even manage to trace anything past 3 of my grandparents, so... Yeah...)

Look up Rømer and Reumer who made the scale that Celcius based his scales on, except for the dumb idea of turning it upside down. Rømer started with 7.5Rø for freezing and 60Rø for boiling.

About the point you made that there's no good way to choose an ascending scale over a descending temperature scale: I think from the pont of basic thermodynamics it makes sense to choose an ascending one since it relates a higher temperature with a higher kinetic energy of particles.

The only absolute way to measure temperature is Kelvin. The boiling point of water is only accurate at sea level. If you're at elevation, this temperature will vary. In Denver Colorado for example, water boils at 95C and in Albuquerque New Mexico it boils at 92C.

So I just randomly came onto this video after watching some stuff on GPT-4 and though why not test it and gave it the prompt "Tell me the origins of the Celsius scale". The lengthy response included: "Celsius developed the scale by defining 0°C as the temperature at which water freezes and 100°C as the temperature at which water boils at standard atmospheric pressure." so I responded "I just watched a video that suggests your previous answer is not accurate" so it asked what the video claims or what I believe was inaccurate. So I tell it "The video is on the KZbin channel @veritasium and he said that Celsius's original scale set 0 degrees as the boiling point and 100 degrees as the freezing point of water which contradicts what you just told me." GPT-4 response: "Thank you for letting me know. You are correct that in his original scale, Anders Celsius set 0 degrees as the boiling point of water and 100 degrees as the freezing point of water. I apologize for any confusion my previous answer may have caused. The Celsius scale was later reversed after his death by Carl Linnaeus, another Swedish scientist who was a colleague of Celsius, to the scale we know today..."

The boiling point of water is different at sea level as opposed to 4k meters above sea level though. It's pretty significantly reduced but I think they must have averaged samples or something at the time of setting the calibration. Very interesting stuff and I'm enlightened. Keep it up Veritasium.

Obviously this will never happen, but we should all be using the Kelvin scale. This is because it truly is based on something that is fixed, unlike the boiling point of water, which changes with varying atmospheric pressures. Kelvin is based on the hypothetical "absolute zero" temperature of the Universe where in an object has no thermal energy at all. Setting this at zero also means that there are no negative numbers on the Kelvin scale.

+Alex Bonte 16 degrees Celsius is 289 Kelvin. The difference between 2 whole number units on the Kelvin scale is very similar to on the Celsius scale, meaning that for everyday life it would be similar to Celsius and fractional numbers would likely be rounded off as is done with the Celsius scale.

[@mattpengelly]

Great video as always. I do disagree with the statement that there's no objective reason to prefer an ascending scale over a descending scale. Since the scale represents a temperature and temperature represents heat density (so to speak), the temperature of something is proportional to the heat energy. It's not always linear since phase changes involve energies that don't register as temperature changes, but generally temperatures increase with heat energy. Since the scale is measuring something driven by heat energy, it seems to me that it's objectively logical that the scale would increase when heat increases. Celsius is still not completely logical from this viewpoint because the Celsius scale has negative numbers and there's no such thing as negative heat energy. Kelvin solves that problem. But aside from scientists, engineers, and people like us that are really into science, the Kelvin scale doesn't have simple points that are relevant to the lives of humans. Thus us using a scale that's based on two important and easily recognized points in the temperature spectrum.

Easy to understand and calibrate thanks to the same grading as Celsius but scientifically perfect and a blessing for all of us scientists. Temperature has an absolute zero and is endless into one direction, so it makes sense to base the scale upon it! Simply rational and makes calculations way easier. Conclusion for today: Kelvin is the best for most science. Celsius for all other science (not involcing physics calculations) and for everyday people because the setpoints of 0 and 100 ° for freezing and boiling water at sealevel just makes sense, is relatable and easily calibrated. Fahrenheit: Stupid... As all imperial units... Nonsensical and stupid... All scientists trapped in countries still using it all convert to metric for calculations...

I’d just like to give Fahrenheit some love here. He invented the mercury thermometer, and his scale isn’t as arbitrary as people make it out to be. It was never meant to be a 0-100 scale - this was at a time when decimal systems weren’t used for most measurements, or even currency. He based his system around multiples of 12, which were used in many other measurement systems and which we still use to measure time and angles. So 0° = the lowest temperature he could stably measure at the time, and 96° = the body temperature of a healthy person (which we now know is closer to 98.6°). He observed the freezing point of water at 32° using that system, and set the boiling point to be 180° higher (another multiple of 12), then calibrated the whole thing so that all the degree marks lined up on those numbers. I believe he was the first to calibrate his system around the freezing and boiling points of water, even though he didn’t build it around those numbers from the ground up. And finally, I’m biased on this one as an American, but I also find that Fahrenheit is more useful for weather temperature, since the 0-100 range of F° more closely corresponds to local air temperatures you are likely to encounter on earth, whereas with Celsius you’re basically limited to the -20 to 50 range… which seems as arbitrary to me as 32 and 212 for water.

[@redbeardreturns3550]

Thank you!!!! My man Fahrenheit needs some cred. I really hate the division between the two measurements.

[@gurratell7326]

Personally I don't see what's useful with Fahrenheit and it's use of multiples of 12, but then I don't see any logical at all with any way that americans measure things either. Using water at the base as Celsius does make way more sense since we as humans and the planet as a whole is based on water, that makes it so easy to understand. But then I might be biased on this one as a Swede that grew up not very far away from Uppsala :)

[@JohnFWitt]

@@gurratell7326 Well, my post was not so much a suggestion that people switch to Fahrenheit as a recognition of the contributions Fahrenheit made to science, such as inventing the type of thermometer that Celsius used to make his centigrade system. The base-12 division seems weird in retrospect, but this was during a time before decimal systems were standard - the money Celsius would have had in his pocket would have included weird 1/12, 1/3, and 1/4 Swedish coins. (Funnily, the US was an early adopter of decimal currency even though we use a weird system for everything else)

[@ZarlanTheGreen]

So... Celsius invented the scale. He created the gradation and the points that would determine the 0 and 100 ....and some other guy just flipped it. A very minor adjustment. Modern Linnaean taxonomy, is significantly different from what Carl Linnaeus originally wrote. The same can be said of Newtonian physics.

Well with the modern knowledge of what temperature actually is, there very much is a reason that our increasing scale makes more sense than the original decreasing. As we now know there is a lowest, but no highest temperature, so with the decreasing scale there would’ve been infinitely more negative than positive integers. We also know that higher temperature means more energy, more speed, more heat, so an increasing scale is intrinsically more sensible.
