I doubt very many science teachers would have said that

[-] EggInDisguise@lemmy.blahaj.zone 74 points 2 months ago

I've had multiple teachers, including at least one science teacher, say nature doesn't do straight lines.

It was just as baffling then as it is now. Especially since I've always had a fascination with pyrite.

Doesn't quartz also do straight lines pretty much always?

[-] EggInDisguise@lemmy.blahaj.zone 8 points 2 months ago

Based on the two large mostly clear crystals from different parts of the world I'm (figuratively) holding, "yes" would be my answer. Although most quartz I come across in the wild is the cloudy chunky kind.

Selenite has a very straight crystal structure. It can even splinter.

Every crystal or crystal like structure does straight lines, no?

[-] Armok_the_bunny@lemmy.world 1 points 2 months ago

Diamond looks to be pretty jagged/rough, but I guess even it does have some straight lines on it.

Snow is just straight lines

Quartz has an octagonal crystal structure, which is the only thing distinguishing it from regular glass. Both are silicon dioxide.

If you melt quartz and let it cool, it will just be regular glass with an amorphous crystal structure. Conversely, if you melt glass and mix in some ground quartz, it will crystalize around the pattern and become quartz.

Even snowflakes are all straight lines! I remember seeing close-up images of them in the science magazines we had in school.

[-] EggInDisguise@lemmy.blahaj.zone 4 points 2 months ago

Crystalline structure in general is basically all straight lines and angles

[-] runner_g@piefed.blahaj.zone 7 points 2 months ago

Biology/organic chemistry don't tend to do straight lines. Inorganic chemistry fucking loves order and straight lines.

My first year teaching, they hired a physical education teacher to teach physical science. About one month in, they also “emergency certified” a secretary so they could get our class sizes below the thirties.

States like Oklahoma and Louisiana are working on taking away the requirements that teachers even have a bachelors degree.

I knew a biology teacher who was a creationist and actively told students that the COVID vaccine was dangerous. And he of course got the Department Head job, because I was a queer.

You'd be surprised how few competent teachers are left

Notice the bevels and chamfers. Not as many right angles as you'd think. Just the illusion

[-] flambonkscious@sh.itjust.works 12 points 2 months ago

Everything is a question of scale, isn't it?

Sure, if you zoom in enough nothing is square / level. The question is what order of approximation are we interested in?

  • magnifying glass

biblically accurate rock

[-] buttmasterflex@piefed.social 9 points 2 months ago

People are mentioning pyrite. There are also many other examples that all fit into the cubic crystal system. Geology, yo!

[-] ChicoSuave@lemmy.world 7 points 2 months ago

Meanwhile, pyrite is disregarded as a fool AND forgotten.

Be careful with that bismuth, one wrong glance and it will shatter into a million tiny pieces
