This is an image of Tourmaline, photographed from two different angles with polarised light.
Tourmaline is Pleochromic, meaning it changes colour as the angle changes. This isn’t a surface effect like the changing rainbow colours on an oil slick, it happens throughout the crystal.
The crystal structure in Tourmaline is anisotropic, which means it looks different from different directions. That means light coming in from different directions experience different effects and can get absorbed in different amounts, leading to something very cool.
It also happens with other crystals, like this Cordierite
There needs to be a video of this!
Here’s a gif. I like gifs. This is Iolite, the gem version of Cordierite, changing colour as the angle changes. Pretty. If you absolutely need a video though, here’s the source
It’s called copula deletion, or zero copula. Many languages and dialects, including Ancient Greek and Russian, delete the copula (the verb to be) when the context is obvious.
So an utterance like “you a bitch” in AAVE is not an example of a misused you, but an example of a sentence that deletes the copular verb (are), which is a perfectly valid thing to do in that dialect, just as deleting an /r/ after a vowel is a perfectly valid thing to do in an upper-class British dialect.
This “If Israel stops fighting, they will be completely annihilated by Palestine” argument is so weak like yes if Israel stopped firing back they will be completely destroyed by rockets that are glorified fireworks that do minor structural damage (if they hit something) and have like a .001%…
