  • It’s easier to layer tops than bottoms. So shorts with short sleeves covered with a button up long sleeve can be surprisingly practical even though it feels silly. Open the button up when it starts to get a bit warm, and remove it entirely when active in the sun. Large diurnal temperature swings can mean committing some fashion faux pas.


  • I’m not a meteorologist, but I do know a thing or two about plasma.

    Plasma is very short lived. Think on the order of microseconds at atmospheric pressures. So unless there was a massive linear source of power along the whole length, this isn’t plasma.

    The visual effects probably have to do with the fact that the sun was very low. I’m guessing the particle size distribution in that line is notably different from the size of particles in the clouds surrounding it, leading to much stronger reflection of evening light.

    I am curious as to the meteoroligical explanation for the line though.


  • They still think that YouTube and Facebook are representative of the average person. They don’t understand how incredible curated those feeds are. I think that’s where some of the “silent majority” mythos comes from. Everything they see is people agreeing with them, therefore it’s impossible that Joe Biden got more votes in 2020.






  • I definitely agree with you, however, I think needing to become self sustaining on earth is a goal that would be well served by trying to design a self sufficient system for mars.

    Earth is big enough that it’s really easy to forget we’re all in the same fish bowl. Entire cities can flush their shit down the river and as far as they are concerned, nothing bad ever happens to them. The scale of earth makes us blind to the problems our actions and methods cause. The ecosystems also do quite a bit to protect us from our own actions

    You can’t ignore externalities in a space colony. Everything must be accounted for. That is what makes it so difficult to design for. Any small amount of waste will still accumulate over time and eventually becomes a problem.

    The tighter scope and strict requirements of a space colony would make it easier to actually objectively measure how sustainable it is. You would know exactly how much external inputs you are delivering each year. We can then take the lessons and technologies that are absolutely required in a space settlement and use them to inform how to better be sustainable on earth. For example, solar cells used to only really be used on satellites, not because they were great on satellites, but because they were pretty much the only option that could stay operational for years. Now PV power generation is helping countries all over the world become a little more sustainable. The harsh requirements of space make us better at problem solving.

    I totally agree that earth is our only option for species survival though. Anyone selling Mars as a “backup” for humanity is either delusional or a con man. I think developing the capability to keep a settlement on Mars is a worthwhile endeavor, but there is no way for humanity to thrive there. Any large scale catastrophe on earth will still be more survivable in select pockets on earth than anywhere on Mars.

    Do you want some discouragement?

    Stainless steel is stains less not rusts never. You would need additional measures to keep the stand from degrading over thousands of years. Your local archeology department could give you some pointers on how to accomplish that.

    Or maybe you design the stand in such a way that the tungsten object is held firmly, but still easily visible in rusty stainless jaws.
