    This has me confused.

    Temperature can be used to refer to how fast the atoms are jiggling (kinetic or phonon temperature) or to how messy, disordered (opposite of ordered) a system is.

    Time dilation is a relativistic effect where time appears to go slower when you are looking at something that has a very high speed (near light speed) compared to you (relative velocity). Can also happen with mass because gravity is acceleration, thus related to velocity.

    If the atoms are jiggling slower, relative velocities only shrink, so you'd expect to see less relativistic effect. I am not aware of any relativistic effects due to thermal motion in normal conditions (room temp, atmospheric pressure), so I don't know how they'd appear when relative velocities only decrease.

    I am really interested where you got this temperature - time dilation link from. Can't seem to crack it.



  • How about solidarity with other addicts? If they see you quit, they will feel pressured to also quit, have you thought about that?

    I did not realize in advance how much my quitting would hurt the other addicts.

    Not quitting fully (either still using on some days or only fully quitting the least popular parts of the addiction) seems to console them a bit.

    It's a tradeoff you'll have to make: do you

    • .. make other addicts slightly uncomfortable by quitting?
    • .. or continue to harm your health, low-wage workers' mental wellbeing, destroy nature and the climate, contribute to pandemic risk and unnecessarily hurt the animals you consume?

    It's not an easy choice.




  • The most mind-blowing moment I've ever had was the course Relativistic Electrodynamics.

    If you assume static electricity (charges attract or repel), then apply special relativity to see what the situation looks like to an observer travelling by, you get magnetism!

    Turns out half of Maxwell's laws is a direct consequence of the other half once you know about special relativity.









  • Software-wise, if you are using a Linux installation with KDE interface, on an AMD CPU and AMD GPU, and are using a wayland session with gamescope to play games, it is very VERY close to the Steam Deck and you are benefiting from all the optimizations that were made for Steam Deck. Bonus points if the hardware is Ryzen 3000 series and Radeon RX 6000 series.

    You probably saw this, but Nexus Mods are asking feedback from Linux users, not just Steam Deck. Because, you know, apart from the sticks, size and touch pads, Steam Deck is just another Linux machine.
