  • That’s just objectively wrong, WA become popular long before Meta bought it, and once it was popular, people kept using it simply because everyone else also uses it.

    And the reason it became popular is because SMS were relatively expensive in most of the world outside the US, wheras internet messengers require only a tiny amount of data per message, meaning even when mobile internet plans were expensive, the cost per message for an internet messengers usually still worked out to way cheaper than an SMS. Also, for a lot of people not having any mobile internet wasn’t much of an option, so if you have to pay for mobile internet anyway whether you use an internet messenger or not, then internet messaging is completely free for all intents and purposes, since you’re paying for the plan anyway, and the messaging won’t use up a noticeable amount of your data (as long as you don’t send/receive lots of media), so why would people pay for costly SMS ? And WA simply was (one of) the first mobile internet messaging apps with good features that worked well. And as soon as it started taking off, network effect made it become exponentially more popular in those countries.



  • And how is that supposed to work ? You can’t fix the healthcare care system or economy in a day, so non wealthy people would still struggle to live as politicians whilst those changes are being worked on, meaning there’s little motivation for them to join politics, and independently wealthy people who are just in it for the power wouldn’t give a fuck about being badly paid. Look at Trump. He doesn’t even take a salary, because he’s corrupt and wealthy enough to not need it, so his salary being low would matter fuck all to him and other corrupt pieces of crap like him.

    The glass of wine is likely due to a selection bias in Tea Total people. Most people who are completely sober, are so either because they are recovering alcoholics, or have other health issues.

    Most people who are healthy and have no prior alcoholism issues drink at least occasionaly, which introduces a selection bias favouring people with health issues as strict non drinkers, which causes not drinking at all to be correlated with worse health than drinking occasionally.


  • In this case it isn’t about improving heat transfer through the bottom of the pan, it’s about improving heat transfer across the bottom of the pan.

    The heat will travel through the pan more slowly because of the added material, but due to coppers extremely high heat conductivity, the copper base will heat very evenly, even if the heat source is unevenly applied, and therefore evenly transfer that heat through the steel layer.


  • Yes it would. Adding material generally makes thermal conductivity worse. There is no material with negative thermal resistance, so adding more will always increase thermal resistance by at least a bit.

    The only exception is 3D geometries, where an increase in surface area due to the extra material can outweigh the effect of the added material, and lead to a net increase in thermal transfer.

    This can lead to a paradoxical effect, where ADDING insulation around a pipe leads to HIGHER transfer than with less insulation material, because the added material increases the exterior diameter, and therefore surface area.

    (Heatsinks are also a good example. It is more material than just the component by itself, but increases surface area by such a massive amount that it more than outweighs the added material)
