came for the art, stayed for the rocks(and the art)
i was wondering and figured youd be the blog to ask, do you know how/why alexandrite changes color like that? i know i could look it up quite easily but my brain is not wanting to cooperate today
This optical effect is called the Alexandrite Effect!
Alexandrite’s chemical structure contains a metal called chromium. The atoms of chromium in alexandrite absorb yellow light. So when light hits the stone, only green, blue, and red wavelengths get bounced back to our eyes. Cutting out all the yellow has some interesting optical results, because it completely separates green and red light, putting them on different teams and making them fight to the death.
Sunlight and fluorescent light contain a lot more blues and greens than reds. So in that lighting the stone is sending way more blue and green light to your eyes, which overpowers the small amount of red light and makes the stone appear blue-green. The opposite is true in incandescent light or candlelight. Those light sources contain way more red light, which overpowers the blues and greens and makes the stone look red! In a mix of both lights you might see both colors existing separately, depending on which angle each light source is hitting the stone.
Something cool to note is that this only works because of how photoreceptors are set up in the human eye. Humans with normal color vision have only got like three types of cone cells, so from our perspective removing the yellow light creates a pretty drastic change in how we perceive a color! Shrimps though? I don’t know what alexandrite looks like to shrimps.

canonize women. make an effort to learn about great women and give them the respect and recognition they should have had all along.
how many times have you heard phrases like “he’s the mozart of coding” “he’s einstein-levels of brilliant” “he’s the new mark zuckerberg/elon musk/steve jobs/bill gates” “he was out of there faster than usain bolt” “focusing with bobby fischer-like intensity” “innovative like shakespeare” and so on and so on and so on?
how many exceptional men have become so easily recognized as brilliant that their names become symbols for greatness itself? how many exceptional women are ever even acknowledged, much less known widely enough to get the same treatment?
canonize women. mention exceptional women and act like it’s a travesty (because it is!) that their contributions aren’t known.

Would eiffel ever watch the labyrinth? He has expressed that he likes David Bowie's music, so would he watch the film for him?
he's definitely seen labyrinth! bowie aside, it's an 80s fantasy movie with a huge cult following, executive produced by george lucas. you don't need a justification for why eiffel would've seen labyrinth; i'd be more surprised if he hadn't.

i think we should remind musicians they can absolutely make up little stories for their songs btw. it doesn’t have to be about them at all. you can invent a guy and put him in situations to music. time honoured tradition in fact.

The secret Dungeon Meshi sauce that's getting people to eat better is that it's so non-judgmental. Senshi and the rest of the gang never talk about what not to eat besides things that taste bad and literal poison. They don't even talk about "health" that much besides the importance of a balanced diet. It's so much easier to eat well when you think of food simply as something your body needs, and that it's often worth the extra effort to make it taste good, especially when you understand how to connect "things your body needs" with "things that taste good"

If my mom sees a significant amount of blood she gets lightheaded, and has fainted on some occasions. Once it happened when we were kids, I wasn't there to witness it but I heard the story from my dad. Basically my brothers, around 7 or 8 at the time, were playing outside while my mom was making their lunch, and she accidentally cut her finger. It wasn't anything serious, but it drew a fair bit of blood and she passed out. My dad saw this and rushed over, but he didn't really know what to do so he just sort of started slapping her to wake her up (not recommended, but he had no idea and panicked)
At that exact moment my brothers both came in from playing, and all they saw was our mom unconscious on the floor and our dad slapping her. So, like, without even saying a word to each other they both just INSTANTLY start whaling on him, like, full blown attack mode to defend our mom. Which obviously didn't help the situation, but she did wake up and everything was fine.
Now our dad says that he's actually really glad they attacked him over what they thought was going on, because it means he raised good boys. And I still think that's true, they're very good boys.

it's an act of love, not just a job i promise. we all want someone who's willing to take care of us in some way, just like how senshi shows care for others by cooking for them :'|

i know ryoko kui is a real one because she wrote 97+ chapters of a manga about fantasy ecosystems and food chains and not once did she write the phrase "survival of the fittest" (it's a bad phrase) (it's a social darwinist phrase even) (hated amongst biologists) (doesn't make sense) (darwin didn't use it) (coined by an business major) (one of the worst phrases in pop science) (no good)
