In an unarmored context, which applied very often throughout history, the spear is easier to use and especially lighter, which makes it a better and more nimble weapon. Spears can also be much longer than heavier pole arms whilst remaining usable, keeping the danger further away from the user

The speed at which one can move a spear tip is impressive and getting stabbed by it has large stopping power. The spear can also parry attacks in a large sweeping area, which makes it hard for anything else than another spear to get through

The more complex pole weapons start to shine in an armored context, where stabbing someone at the end of your long pointy stick becomes harder. Then, the hook-y, chop-y and spike-y bits of the halberd can really help tackle the armor

I'm not sure if my comment is whoosh, but just in case; it's the transliteration of the letters in the picture if you read them as cyrillic letters, highlighting that they should be understood as faux-cyrillic instead

I'm sorry but you can totally control the margin size in LaTeX if you learn the right incantation

then you spread the entrails slightly and stab towards the sky. Really don't see what the big fuss is all about.

I took "rather than the other way around" to mean "rather than negatively-correlated" in this context, since positively was emphasized

We had to replace the entire screen assembly for that at the time but I'm sure it's possible to do something less drastic if you are just working on your own machine

I worked on repairing Macs during that period and I suspect that no wifi card except this specific one would fit in the relevant slot of the machine.

They weren't standard formats as far as I know and couldn't be used across models because the shape of the actual card was never the same. It's possible the connectors didn't change though, or that a third party manufacturer made new cards specifically for that model, although that seems unlikely.

Another commenter (u/bloodfart) wrote that the connector was a standard mini pcie connector; I can't confirm but that's plausible and would mean it's a lot more likely that an upgrade may be possible

One note of caution, it was really easy for an uninitiated repair person to sever the antenna wire from its connector when trying to disconnect or reconnect them, the cables are quite thin

Getting books from the library to read?

I don't know what chain reaction exactly they were thinking of, but from modern fusion research, I believe we can confidently say that the atmosphere would need to be interior-of-a-large-star-level dense, and even then I'm not sure you'd get nitrogen fusing with anything without a lot of hydrogen or helium around. Nitrogen-nitrogen fusion seems extremely implausible for sure

Yeah I would say that one could explain the picture here

Ultimately, the phenomenon is happening much much higher up in the atmosphere, so being a few kilometers closer vertically won't make a difference; but by being further up on the ground, you could see an aurora from further away and through a lot more molecules that could scatter non-red light

That's a cool photo, thanks for sharing.

For more context why this wouldn't be related to redshift, redshift is a concept in physics for light that's analogous to the Doppler shift for sound. The typical example of Doppler shift is the EEEEE-OO-UUUUUM sound a car makes when moving fast past you. When the car is speeding away from you, the sound pitch is noticeably lower

Similarly, when a light emitter moves away from you at extremely fast speeds (i.e. hundreds of millions of meters or yards per second), the light you see reaching you will be shifted down in frequency, towards red in visible light. This can happen in other more complicated relativistic situations too but they are less easy to explain and also not applicable here

I don't know why the people in the photo see this beautiful red aurora but redshift is almost certainly not a related concept here

The answer is almost certainly no but I'm curious why you think this might be the case
