  • You’re correctly identifying thermal mass as why they feel cooler to the touch, but this is mixed up in some incorrect and contradictory statements. You seem to keep changing your reasoning behind why tiles feel cooler to the touch.

    The ceramic tiles in your house aren’t really “colder” than you

    This is incorrect, and why I replied to begin with.

    Flooring is colder than your skin, regardless of the material, unless your floor temp is above 92℉ (33.5℃). You can measure this with a thermometer. If something is the same temperature as your skin you won’t feel anything - there’s no heat transfer. You could have a copper floor if it was the same temperature as your skin, you wouldn’t feel a thing.

    [Ceramic tiles] also have a high thermal mass … they easily lose heat to the air.

    These two statements are directly contradicting one another. High thermal mass means it takes a longer time to lose heat to the air. Given identical conditions, ceramic will take longer to change temperature than fabric. For example, if you opened a window and it was 40℉ outside, the carpet would drop in temperature faster than the ceramic tile. It wouldn’t feel this way to your skin, but it could be measured with a thermometer.

    That thermal mass is why tiles feel cooler than carpet. Your body has no issue warming the fibers in carpet next to your skin to the same temperature as your skin, it’s harder to warm up the tile because of the thermal mass.


  • You can hold a ceramic tile in your hand and apply a blowtorch to the other side. They’re better insulators than conductors. That’s why you see ceramics used for insulating hot food bowls from wooden tables, or a more extreme example, ceramic tiles on re-entry vehicles. Ceramic is not a good conductor of heat.

    Wood is about 0.1 W/mK, ceramics about 1 W/mK, and copper is about 400 W/mK.

    The ceramic tiles in your house aren’t really “colder” than you

    Yes, quite literally they are colder. You can measure this with a thermometer. A more apt comparison would be ceramic floor vs wood flooring, or ceramic vs air temp, as all this flooring is at identical temperatures, yet feels different to the touch.

    Tiles do not feel cooler because they “easily lose heat to the air”. Quite the opposite; they take longer to heat or cool than fabric or wood due to their thermal mass. This is also why they feel cooler to the touch. Your body can warm the low mass of fabric or wood faster than it can ceramic, thus those materials feel less cold when you step on them.

    If you’re going to be pedantic, at least do it right.




  • Thanks for elaborating. I knew limits were going to show up.

    You make a good point, although I would like to point out that one hundred quinvigintillion is basically right next to the number 1 on the number line that goes to infinity. The chance of the monkeys not writing Shakespeare is infinitesimally small. You winning every possible lottery every day for the rest of your life is infinitely more probable than the monkeys not writing Shakespeare.

    There’s 100% chance that all of Shakespeare’s and all of Trump’s writings will be started immediately with infinite monkeys. All of every writing past, present, and future will be immediately started (also, in every language assuming they have access to infinite keyboards of other spelling systems). There are infinite monkeys, if one gets it wrong there infinite chances to get it right. One monkey will even write your entire biography, including events that have yet to happen, with perfect accuracy. Another will have written a full transcript of your internal monologue. Literally every single possible combination of letters/words will be written by infinite monkeys.





  • If you tell someone that fedi instances are like email providers and that your instance is transfem.social, that creates three expecations in your audience:

    1)The main, or possibly only, way to access your fedi account on a desktop is through the transfem.social website.

    2)The main, or possibly only, way to access your fedi account on a smartphone is through the transfem.social app. This app is completely separate from the apps that could be used to access a fedi account on another instance.

    3)The primary difference between transfem.social and other fedi instances is the UI of the website and app.

    Frankly, I don’t think this is that big of a deal. First introduce them to an instance, then once they figure that out, show them the apps and other ways to access that instance.
