#mohs hardness

It absolutely boils my blood how tech enthusiast are still demanding sapphire crystal be put on phones instead of glass. They call that shit "basically indestructible," and it pisses me off to no amends.

"Scratch Resistant" and "Drop Resistance" are two opposing lines. As one increases, the other decreases.

We know this because plastic won't shatter in a lot of cases that glass will, but glass won't scratch as easily as plastic.

The same is true for Sapphire and Glass. Sapphire is much more scratch resistance, yes. However, it's far more brittle than glass.

People often tout Sapphire as the super material of the phone's future, but Glass is already that.

It's hard enough to prevent most scratches and drops in day-to-day life, all while being relatively affordable.

Sapphire displays would increase purchase cost, increase repair costs, only slightly increase scratch resistance, while dramatically decreasing drop resistance.

Every now and then when you draw Emmet with one of his Pokemon you also show them have a nickname.

If it isn't too much to ask for I'd like to see all the nicknames you came up with for the twins Pokemon.

So far, I think they're adorable!

so many names!!

thinking about how alabaster has ten rings to syenite's (official) four.

thinking about how innon tells syen that she is stronger than alabaster, because he has broken many times over, while she keeps pressing through.

thinking about how she chose her orogene name because syenite (the rock) only grows stronger under pressure. thinking about how syenite (the rock) has a mohs hardness rating of 6, while alabaster (the rock) has a hardness of 2.

you find this at home. what would you do

'im about as hard as flourite right now :/' is how i respond these days when my imaginary taste dick is above limp but not quite hard, hence the thing im talking about is mid

something that really pisses me off about twilight (after all that racism) is just how little effort SM put into research (unless of course it was coming up with historically accurate confederate names) because she got so close to doing something so cool.

like everyone knows that the twilight vampires aren’t really vampires in the normal sense the sparkles, the lack of fangs, that one post saying that they’re much closer to fay than traditional vampires.

but something else about the twilight vampires is that they are constantly being described as stone-like and being compared to marble which is why they’re so indestructible. and the cursed knowledge that vampires kissing sounds like teacups clinking against each other from bree tanner.

now i’ll admit it’s been over a decade since i last actually sat down and read any of the books BUT to my knowledge (feel free to come correct me) there is no explanation for how vampires actually become like living statues aside from it being from vampire venom.

so what if they were literally living stone? like what if the way these vampires had their bodies preserved through time is the transformation calcifying their bodies. because soft tissue can become calcified the famous example being mary shelley keeping her husband’s calcified heart.

and to take it a step further they’re bodies being covered in a layer of calcite would account for the sparkling.

Throwback Thursday!

FRIEDRICH MOHS

In January of 1773. A man by the name of Carl Friedrich Christian Mohs was born in Germany. He studied chemistry, math and physics at the University of Halle. He became a member of the Mining Academy in 1798.

In 1801, he became a foreman for a mine and in 1802, he moved to Austria to identify minerals in a private collection. Thisbwas the beginning of hia biggest achievement yet. In 1835, he began to classify minerals by their physical characteristics, something that was at odds with the current chemical systematics.

However, ancient peoples had measured the hardness of minerals such as diamond scratches quartz therefore it is harder. This became the basis for MOHS HARDNESS SCALE and it is still used today.

Throwing rocks at whoever popularized the concept of "healing crystals" to the extent that you can't find real information about minerals by just googling it

[sugarandice3]

When I was younger there was this older cousin that was a bit of a bully and one time he tried to convince me that some broken glass he found was diamond. I didn't believe him NOT because we found it on the ground OR because it very obviously looked like broken glass but because I was a rock nerd and it didn't pass the Mohs hardness test.

Got really happy searching types of minerals on my school computer today 👍would recommend

It’s always interesting to see how characters’ death quotes change from one chapter to the other or from the game’s regular chapters to the post game’s chapters. Ozma’s last thoughts on CODA are that she hopes Lodis can change, with or without her.

Another level of disconnect I’ve seen is how people discuss the buyers of poached items.

Just like with poaching, it’s important to understand the underlying pressures in order to stop the problem, and a lot of people fail at this by chalking it up to individual greed and callousness instead of considering the cultural pressures at play.

For example, I used to work in a job related to combatting the illegal ivory trade, and when I told people what I did for work, I’d often get some xenophobic response like “Omg why do rich people in China need to show off their wealth by owning dead elephant body parts?!”

When someone said something like this, I’d eye their left hand to see if they were wearing a wedding or engagement ring, then say “Hey, is that a real diamond?” (or “Is your partner’s ring diamond?”)

Most people would answer yes - that they or their partner owned (or expected to eventually own) a diamond ring.

I’d follow this up by asking if they’d ever consider owning/proposing with a non-diamond or lab-grown diamond. After all, most diamonds are unethically sourced, and many diamond alternatives are just as strong, beautiful, or even indistinguishable from diamonds (not to mention way cheaper!)

“Oh, I would never! It’s just not the same as having an authentic diamond!”

Bingo. There it is! That’s the same reason people justify buying authentic ivory instead of buying fake ivory or other cultural signifiers of wealth.

The same logic applies to many of the components in our electronics, but you don’t see many people batting an eye when buying the newest iPhone. Human workers are treated deplorably in the metal mining and sweatshop industries, but it’s easy to disconnect yourself from your impact on the world when you really want something.

You are not immune from propaganda strong societal pressures.

I know Tumblr loves a villain. But we can’t approach every issue like it’s 1792 and we’re tired of the French Monarchy. When combatting widespread issues like poaching, if you actually want to reduce the harm being done, you need to implement effective policies, and this requires putting moral judgements aside and acknowledging the humanity of the people taking part in the harm.

I saw this post and idk it made me feel some type of way. I may get flack for this but idc I feel it must be said. Poaching is a lot more nuanced than “bad people kill animals.”

Poaching, especially in Africa, is a byproduct of colonization and poverty. Although poaching existed prior to European colonizers, it was not done at a scale and frequency that would threaten wildlife populations. Poaching exploded under colonial rule where things like ivory, pelts, hunting trophies, and in some cases, land were prized and sought after by European settlers. This led to an initially boom that devastated local animal populations and cause some tribes to become very reliant on poaching as a means of subsistence.

Additionally, due to poverty, people are still being driven to poach animals, even endangered animals because it’s a more profitable way to support oneself and community, and predatory animals can be poached because they threaten and devastate local livestock. Anti-poaching measures rarely take into account the human and economic drive behind poaching. You’re shooting and killing poachers but what about their families and communities that they support? Are those animals in a better place when there more people waiting to hunt them? Anti poaching measures don’t actually care about eliminating poaching, if they did they’d come from the angle of human and economic development and community improvement. Because let’s be real, if those people living in their poor, rural, undeveloped, undereducated*, regions with not many opportunities turn to poaching, it’s not from a moral standpoint, they’re chasing survival.

African governments be corrupt af, keeping all the money for themselves and leaving masses in poverty then erect some anti-poaching laws to please smug westerners as if they aren’t driving people into desperation. And then poaching rings take advantage of this desperation, much like a gang would, and supply them with guns and a promise of a better life. And bam, you have a poaching problem. So long as you have people in desperation, poaching will still be a problem.

Like many social issues; drugs, violence, crime; a closer look and you’ll find that poverty and lack of opportunity are at the bottom of it...
