  Isn’t a tensor the generalization of scalar, vector matrix and so on? (PLUS the invariance under coordinate transforms?)

  A box would be 3-dimensional indicating that tensors have 3 indices when in reality they have n-indices. Ir am i reading it wrong?

  The big difference that I see is that they investes in people for a long while now. They did what they can so people can get a decent education. That’s also the reason why they don’t allow kids to use tiktok and so on - it’s hindering the next generation’s ability to think. They know that you need many intelligent people to drive whatever other innovation you want to have later. That’s why they’re pulling ahead so fast while we are collapsing. I am not even living in the US, but even here the education system is crumbling.

  The west has trapped itself in the thought of technology without people. The idea that few clever people can design perfect systems that drive everything for us. That we just need to support those few individuals to get maximum return. China is supporting the broad masses. It’s like creating a fertile soil.

  Who knows what all the asterisks are causing in the future. But at the moment it’s just no comparison. We’ve gone backwards, while they’re so far ahead we barely see them.

  It’s used like sweating. We lose heat by havibg water evaporate off our skin. Right now get warm water and put it on your arm, then blow on it. It gets cold until it is fully evaporated. For water to change from the liquid to the gaseeous phase it needs energy. Think like water molecules are holding hands in a liquid. If one of them wants to come free and fly through the air it needs to somehow get the energy to break free from the grip of the others first. When water evaporates from your arm it tales this energy in the form of heat. It turns heat and uses it to get to the gaseous phase. As long as there is water on your arm it can be cooled that way.

  That’s what data centers do as well. They take water to cool their processors and the let part of it evaporate into the air. That way the parts of the water that remain are like your arm - the get cool quickly.

  It’s very effective. But if you live in a small town and next door there’s a massive datacenter that takes out all the groundwater and basically just boils it until it disappears, you might get angry after a while.

  Yeah i din’t think of complete (=admin) access. Maybe that’s a good thing to keep to oneself. There could be an inheritor which would gain access if ypu would abandon the project.

  But regarding lower level administration (blocking stuff, checking that rules are followed and all that - things that take up most of the time of an administrator working in social media) could ve delegated maybe? Similar to reddit moderators of subreddits. It would be nice to have transparancy of which moderator moderates which other communities.

  Maybe you could think of a way of finding some people in real life that could be a promising candidate.

  Thanks for the reminder. Just added a standing order. It should be executed late in the month. I started low, but i could slightly increase it. It would be nice to read an update on the situation maybe ins 1-3 months?

  I think it would also be a good idea if you don’t shoulder everything alone … Single point of failure and all that. You could think about which tasks ypu could (partially) delegate to other people in order to have less workload.

  It would make sense to setup a roadmap for ypu maybe? I don’t think it’s healthy to have administrating take up so much space that you cannot work another job.

  Let us know where you might need support :-)

  And thank ypu very much! I quite like it here!

  That’s why there’s quant mechanics. The simulation can always invent invent thinga on the fly to reduce computational load. It’s like lazy execution when soneone’s looking i.e. me - let’s not kid ourselves: the simulation is only simulating my surroundings - of which all af you are part of. Yadda yadda, there’s only me.

  On another note: the simulation can also always rewritebparts of my brain and retroactively change stuff in my memory making me believe different things. So i could also be reprogrammed to believe I saw this or that insteas of

• ⁨Comment⁩ on ⁨The ‘Profound’ Experience of Seeing a New Color⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Captain Obvious would like to chime in: (sorry 😅)

  Every color that we see is created by different types of receptors being stimulated together. A linear combination of three of these types. Arguably there isn’t really a wavelength that only stimulates one type of receptor exclusively as their absorbtion areas overlap - so it isn’t even that precise to call one receptor the “green” receptor as it sees a continuum of wavelength (of which a lot are also detected by the (so-called) “red” receptor.

  It’s a little egg-and-hen-problem with the naming here.a way out of it would be to only speak about spectra if it’s in the physical realm and color of its in the percetral realm.

  Now we’re talking!

  Well doing it so abruptly would probably cause a lot of trouble. I would already be glad if there was a transitional phase where ip would cease to exist once you’re dead and next would only last for x amount of years (not your entire life).
