  • I often hear americans (even scientists) say that they prefer the Fahrenheit scale for weather forecasts, but I believe the perceived higher accuracy is an illusion. Forecasts aren’t that accurate for any given micro climate.

    When I switched from Fahrenheit to Celsius I used a rough heuristic to get the Fahrenheit value from Celsius. What I discovered was that my heuristic, which was rounded and would skip entire degrees Fahrenheit, matched most weather apps’ Fahrenheit value.

    For example, if my app said 20°C, the other person’s said 68°F. If mine said 21°C, theirs said 70°F. If mine said 22°C, theirs said 72°F. If mine said 23°C, theirs said 73°F. It is very rare that mine has said, say, 21°C and theirs has said 69°F (or any temperature where the value was converted with decimals and then rounded).

    That is to say, my experience certainly seems to indicate that for people using the same weather sources but in Fahrenheit, the value was still rounded to the nearest degree Celsius, then converted to Fahrenheit and rounded again.

    That’s not to say you’ll never see 71°F or 69°F or other values that aren’t converted from an already rounded Celsius value, it all depends on what your data source is providing you. But nearly always, my rounded conversion from a rounded Celsius value matches what other people see in Fahrenheit.

    This makes complete sense, because most people cannot tell the difference between 70°F and 71°F. And it’s difficult to predict regardless.

    Edit: this could also just be a lack of sampling and dearth of values where the rounded-converted-rounded value differs from the converted-then-rounded value. I don’t know.


  • Copying this post I made elsewhere recently:

    I used to say this. But being a curious person, and one willing to test my own hypothesis, I decided to learn Celsius. Like, spend enough time with it to intuitively understand it, so that I could compare the two.

    Almost six years later, I haven’t switched back. I much prefer Celsius for weather. Having 0° at freezing is far more useful than I suspected it would be, and having less granular degrees gives them more meaning, which makes understanding them easier.

    Seriously, I struggle to express just how useful below-freezing temperatures being negative is. -5°C means so much more to me than 23°F, and that’s after thirty years of using Fahrenheit and only six of using Celsius.

    Edit: this isn’t to discount what you’re saying, just to offer my own opinion on the matter. Having experienced both, I much prefer Celsius. But obviously everyone will have their own opinions.



  • That movie made me so mad.

    The book I, Robot is a series of short stories presenting situations where it seems like robots didn’t follow the three laws of robotics and then explaining how they were caught up in loopholes, essentially. It’s great.

    In the movie, the loophole is: “We put a second brain in the robots that doesn’t follow the three laws of robotics.”

    (I might be wrong, it’s been a very long time since I’ve read the book or seen the movie. This is just what I remember.)

    F for temperatures affecting humans, C for science.

    The range humans can survive in is roughly 0 to 100 in F, the full range of the scale. The range in Centigrade is roughly -17 to 30

    Minor correction:

    30°C is a relatively normal temperature for much of the world (not necessarily all the time, but during the hotter parts of the year at least). That’s 86°F. Where I am in Michigan today the high is 32°C.

    0°F to 100°F is roughly -18°C to 38°C.

    “Thirty is hot, twenty is nice, ten is chilly, zero is ice.”

    (I’ve heard this as “ten is cold,” but to me ten isn’t cold, it’s just starting to get chilly. 10°C=50°F, and I wouldn’t call 50°F cold (depending on the season, I guess.)

    Off topic, having spent my whole life using Fahrenheit until about six years ago when I decided to test the “Fahrenheit is better for describing weather as it effects humans” reasoning I always used by switching to Celsius on all my devices…I personally much prefer Celsius. It is remarkable how much more meaning I get from -5°C than I ever did from 23°F. Because a degree Celsius is less granular than a degree Fahrenheit, learning the meaning of a degree is much easier. And because the below-freezing temperatures are negative reflections of the above-freezing values, it’s much easier to understand cold temperatures in Celsius (in my opinion).

    Consider vapes, rather than smoking. You can get your nicotine without the worst side effects. You can also taper your nicotine levels over time, so you get less and less. That’s what I did and it worked well for me. Eventually I just stopped vaping, and since I had tapered my nicotine levels I didn’t really crave it (other than the activity itself, but even that went away unless I think about it specifically).


  • Unless you’re going about it like an asshole, no. You’re communicating, standing by your position, and setting a boundary.

    She knows smoking is dangerous, she knows you don’t like it, she knows you want her to quit, she’s quit before so she knows how to do it.

    Have you considered compromising with vapes? Still not as good for you as not smoking at all, but significantly healthier than smoking and doesn’t make everything smell horrific. She can get that nicotine buzz she craves with very few of the downsides. She can also then taper her nicotine content and quit that way if she decides to.


  • But really breasts and the nipples on them aren’t inherently sexual and it’s tiring men think/act as if they are.

    Inherently, no, but they are secondary sexual characteristics that our species has selected for long enough that the lizard brain instincts find them sexually appealing.

    The problem isn’t that men think they’re sexual or find them a turn on. The problem is men not knowing how to control themselves.
