  • Oh! That’s nice to know about mining, making it safer for workers! But there’s still the environmental impact… A few years ago, I was talking with a mine engineer who seemed proud to say that they had to move a lake to mine. He claimed that simply shop-vaccuming fishes from one place to the other was good enough…


  • The only thing to keep in mind is that although particles are dimensionless (as far as we know), the do not exist without context. Spin relates to how a particle is linked to the rest of the world.

    One way of seeing it is that spin can be represented by a “rotational polarisation” of the surrounding cloud of virtual particles.


  • It’s clean regarding chemical waste.

    I’ve helped build nuclear waste caskets, nothing is perfect but the amount of attention put into making it safe is incredible! The layers (and quality) of stainless steel welds would put your average steel bridge to shame…

    But fission will always be limited (as in non-renewable). If everything was powered by nuclear, I’m sure we’d see even more awefull mining operations. Also, fusion should in theory be much better, if the thermodynamics of it end up working.









  • There’s an argument to have about conservation of culture, which is a thing in itself. (Why do people want to preserve antiquities?) There must have been some awesome poems in Sanskrit that we’ll never know.

    Mostly apeaking, for me the simple fact of wanting other languages to die is a huge red flag of attempt at cultural erasure, like when the english tried to eradicate Scottish culture. Language erasure is a tool to marginalise those speaking it, and history shows that it never really end well…








  • Very on-topic SMBC today: http://www.smbc-comics.com/comic/mary

    There are multiple types of color blindness, most of the time they affect the production of a specific cone inthe eye. Deuteranomaly is the red-detection cone being affected, and causes issues distinguishing red/green colors, but also blue/purple. It’s a “hardware” issue caused by less or lack of detection.

    I’ve heard of “software” version of colorblindness, but it doesn’t seem to be as documented as others. I have a younger sibling that seemed to have “copied” my deuteranomaly despite being able to pass the “hardware” tests…

    The exact neurons in the eye and the brain being triggeres are the same for detection of color, but where the “qualia” differs is to which external interpretation they are linked to. If we were able to isolate the souvenirs/associations that come from specific colors, I’m sure in general people would see the same colors.

    Just like touching something hot triggers the same neurons as touching capsaicin, it creates a signal to the brain. What happens inside the brain depends on the life experience of each, but the initial signal is the same, and it can be proven with fMRI.

    Off course, if we want to define a “qualia” as “the thing that can’t be proven by science”, then off course it won’t be provable using science. What is it, though?
