Lightning Ridge Black Opal - Twin Galaxy Gem Stones
Aside from Grey and White, Black Opal is the most precious and is at least 50 times more rare than diamond, yet these beautiful gems are also much more fragile.
The brilliant colors within the gems are iridescent, meaning that they will change color or flash as you rotate them. Deep down within the opal are silica spheres arranged in arrays and both the size and arrangement of the spheres will determine the color produced. The Twin Galaxy Stones will flash like lightning as you rotate them, hence the name Lightning Ridge in Australia.
this was my final test in art today
i’m glad students aren’t the only ones who give up at the end of the year
you can now purchase a destroy capitalism banksy print from walmart
THIS CHANGES EVERYTHING.
has anyone ever stopped to think about what ridiculous animals goats are
WHAT THE FUCK
HOW DID YOU EVEN GET UP THERE
ARE THESE ANIMALS EVEN REAL
????? ?? ? ???????//
SOMEONE FUCKING EXPLAIN THIS SHIT TO ME
Part one of a collection of best tweets found in the #bisexualfacts twitter tag.
as a bisexual, i can confirm all of these
"average person eats 8 bisexuals a year" factoid actualy just statistical error. average person eats 0 bisexuls per year. Bisexual Georg, who lives in cave & eats over 10,000 each day, is an outlier adn should not have been counted
“That seems sort of harmless but then it kind of gets a little darker and sort of accuses these young pop artists of being part of this cycle where girls read magazines, feel terrible about themselves ‘cause its says “you should be skinnier, you should be prettier”. They feel terrible, and then these pop stars tell them that they’re perfect and that they’re beautiful and they buy the songs and then the popstar’s on the cover of the magazine so they buy a magazine again and it’s sort of this vicious cycle and I sort of implied he’s working for Satan or whatever.”
So what do a human hair, a steel pipeline and an amoeba’s flagella have in common? Once they all assume the right proportions, they all work the same. A miles-long pipeline, though it can be massively thick when looked at up close, looks like a long, spindly hair when it’s spread across the landscape. When a hair is short enough (like a military buzz cut) it’s sticking out from the head directly as it grows. It’s short enough that its internal strength can stand up to the force of gravity. As it grows, however, it has to ‘carry’ a longer length, and gravity pulls it down.
Even those of us who aren’t at MIT — or working for Pixar — can see the interplay of gravity, exerting a force in in one direction, and the structure of the actual ‘hair’ curling in on itself. Grow a hair long enough, and its own weight will pull it straight. However, as you get to the very tips of the hair, which don’t have as much weight on them, the curl will come back. The more towards the end you get, the less weight is on it, and the more extreme the curl.
You can see this successfully rendered in the table scene above. Although it’s clear that the young boys have larger, softer curls than the girl, the hair on the top of their heads is piled up, while hers is pulled straighter than the rest of her hair. The weight is pulling the top of her hair straight while the bottom is in tighter ringlets. In real life, people will notice that their ‘straight’ hair will curl at the end, showing that what they have is curly hair that only has enough strength to curl at places that don’t support a lot of weight. Meanwhile, in the macro scale, an oil pipeline will ‘curl’ in reverse. Its length it set out horizontally, so gravity ‘pulls’ its straight structure into a curl. Shifting earth or driving wind can cause it to curl in on itself, at exactly the point that are feeling the most force. The ends, or the parts that are supported by struts, will remain. A straight pipeline is, essentially, a curly hair in reverse, but the interplay of forces is the same.
