  • What happens to the human body in 49C heat? Australians are finding out

    Jump

  • I agree that Celsius’ definability and reference points are more sensible.

    All I ever say on this is that F has its appeal in everyday usability terms, because of how nicely 0-100 encapsulates our comfort zone. Not that it’s designed that way, it just happens to work nicely.

    And whenever I say this much, people (not you) begin screaming at me about how I need to live my life by water’s phases changes :/

  • Boiling water is full of pockets of steam that may be higher than 100C, and will have cold spots too. It’s really not very easy at all to get any quantity of water to 100C stably and consistently throughout. Not easy enough to be a foundational reference, with the tools of a century or two ago. Boiling is also sensitive to altitude and pressure changes, and may be shifted slightly based on the mineral content of the water. It is in fact not dead simple.

  • I explained it in objective terms. Human habitability range. We’re in a thread about weather exceeding what humans can withstand. That point is pretty easy to remember in F, as if the scale were determined by the extremes we can withstand, a fairly relevant range, regardless of what anyone is “used to.”

  • You may be shocked to discover that we can also measure the temperature of water in F.

    Your talking right and wrong is beside the point. No one scale is superior for any use, strictly speaking. The pint is that 1-100 in F relates in an intuitive way to the range of human habitation. That’s a more intuitive thing to base a scale on in my opinion. Now tell me my opinion is wrong, I dare ya!

  • I appreciate the elegance of your field calibration, but it will not be “exactly right.” The boiling point of water is readable repeatable but sensitive to altitude and the contents of the water. Freezing is also sensitive to salt and mineral content, but even more basically: where’s this “freezing water” you can stick your thermometer into, that’s reliably == 0 degrees? Ice keeps getting colder, and melted water can be any temperature above 0.

    Good in theory, but even if field calibration were a real need, it’s not very exact. And anyway, if you can work all that out, you can do it for F or C. Since no one will every forget 212 and 32, as you point out.

  • This is why almost everyone does development, not research.

  • Metric is superior for conversions.

    Imperial’s basis on body parts makes for highly intuitive human-scale measurements.

    I don’t spend all my time converting measurements, I guess. The 10x jump in increments sometimes leaves big gaps in usability. Centimeter level precision isn’t enough for carpentry. But I can’t read my ruler with milimeter precision unless I get out my glasses and turn all the lights on. 1/8ths of an inch are precise enough and easy to see. 🤷‍♂️

  • 1-100 Celsius is about water freezing —> boiling and I’ve always been confused about why it’s so eminently logical to understand the weather by that scale.

    1-100 Fahrenheit, meanwhile, is a really reasonable approximation of the habitable range of temperatures.

    And you just showed this by having to establish for everyone that the upper bound of habitability is 37C. A completely random number anyone would forget.

  • If you can’t get excited by incremental advancements, you should probably unsubscribe from science as a topic.

  • (2% of) Scientists (over there at the fringe) base results on politics!

    Once something is wildly misleading, it loses all claim to being accurate in any measure. This is the kind of “accuracy” that Satan applies when lying based on a grain of truth.

    Jump

  • One factor here is that they are all under pressure from their boards and investors not to miss the AI wave and get left behind. All companies are doing some level of AI theater. Some actually believe it. But it’s not like hundreds of CEOs all came to this judgment purely on their own, with no outside influences. It’s a mass craze.
