He didn't say "pretty cool right?". I'm fucking sobbing and shaking

Also known as Icelandic spar the Vikings would use these crystals to find the sun on a cloudy day while out at sea that way they wouldn’t get lost

he has the eyes of a pixar character, its almost terrifying how pretty they are

You know he’s serious when he uses integrals and limits as the background.

We use these in networking. This is how we use something called a circulator. It allows for bidirectional optics or fiber use. Meaning you can use a single strand of fiber for send and receive vs using a pair of strands of fiber (one for transmit TX and one for receive RX)

What happens if you put 2 of them right after each other?

Every video this dude posts I just gain knowledge. Its so dope.

Someone else mentioned that this is also known as Iceland Spar which the Vikings used to locate the sun on cloudy days for navigation purposes. Another moniker for the calcite crystal is Viking Sunstone. Calcite crystals are pretty common and are actually one of the most abundant mineral, but it does not commonly grow as one large crystal as seen in the video. When it is of the same quality as the one presented in this video, it is known as Optical Calcite (or Iceland Spar/Viking Sunstone as previously mentioned). Iceland has some of the largest deposits in the world of Optical Calcite hence the Iceland Spar name. There is only one mine in USA that mined for Optical Calcite located near Anza-Borrego and The Salton Sea. It was operated by a small team (I think 6-20 people) during WW2. The calcite was needed for it's double refraction properties in the production of the Norden Bombsights.

big “only became hot after high school” energy, it’s so endearing

Awesome I call it Drunken Glass

I was so excited to visit the ankansas diamond mine park as a kid. After hours of digging, I found a calcite crystal, which kinda looks like a diamond at first. I was super excited and thought it might be a real diamond, so we took it to the main desk. The lady behind the counter explained what it was, then my dad asked if calcite was edible for some reason. She said "I guess it won't hurt you" and my dad ate it. And 6 year-old me cried. That moment has been seared into my memory for almost two decades.

Bro is just straight up beautiful

Just remembered I should comment instead of just watching...your stuff is always interesting and fairly informative, even these shorts. Thanks for posting!

I don’t wanna look at integrals anymore and sparse fft, I had enough of them for my digital holography dissertation. Love your vids bro.

Imaging a drunk guy looking through this crystal

If minecraft calcite was like this, it would really change the game.

Where can I find a large and clear cut with that clarity? If you don't mind me asking.

This guy is a big nerd, and I love him for it lol :) keep it up man !! :) your doing great.

the legend says that he still didnt said "pretty cool, right?"

So… my eyes are just giant crystals of calcite? Cool. Good to know.

Glad to see you on shorts! Love the overload I’m getting right now

Shorts moment

the girls in his science class love him

Love seeing these new shorts!! You do very well with this format! Keep it up! And thank god youre still alive!!

A sun stone....

This is my laser unlike my psychotic stare it's attention splits when put through this crystal that's shaped like my soul.

Wow, he also demonstrated my vision when looking at a Physics textbook.

That double vision is epic

So when you put a polarizing filter in front of it and rotate it, you see the two images alternating?

this is epic

God imagine doing multivariable calculus with lenses like these

You also get the same result by being cross-eyed.

Okay so take like 5 of them put them in a line and than Strap everything down and rotate it, giving the effect of a laser minigun. Than take a couple mirrors and some prop making, and bam! Laser minigun for a cosplay right?

I am probably having a physically bad night but I keep seeing your shorts on my recommended so it’s okay :) good video!

The 2x laser upgrade in real life

Im gonna attach this to my sniper and scare my enemy to think theres two snipers on him

Is it weird that I’m attracted to him like crazy - it’s all the intelligent / brainy stuff that does it for me 😂

We have science people like him and we still have flat earthers smh.

""Pretty pretty cool cool right? right?""

“ Double refraction” is basically my eyesight :D

First comment UwU

I wonder what would happen if you had a room full of mirrors reflecting each other, and just add that into the mix

I love this kid , man hes so smart hes gonna do very well and come up with some cool stuff in the future 👌

When you have eye problems and don't need calcitie to see double

Your videos are hands down the most interesting one's on KZfaq! Honestly I look forward to watching what you have to share more than anything. 😄

I work in an optics shop that processes and polishes these down by hand into different types of polarizers. Its a very tricky material to work with.

I've been watching your videos for years. Thanks for making shorts. You're my favorite science KZfaqr. I really love your videos explaining all of the complex physics and electronics behind lasers. Glad your channel has grown so much.

My vision without glasses:

As a dr stone manga reader, i love how they implement the use of calcite to navigate in the sea.

Calcite is the new block added in 1.17 which you can find in amethyst geodes

This is exactly how everything looks without my glasses on

This man said "double refraction" and went to double his fractions

Dude...by far the coolest, most informative shorts on this site.....love the stuff brother

He has millions of souls trapped in that crystal. Including my cat's.

Ha, you need a crystal, i just need to take off my glasses!

After putting that refractive crystal on that integral it looks it came up directly from hell☠️☠️

I want to see a laser passed through this between two mirrors, refracted and doubled until it cant anymore. I need this

styropyro on his main channel:haha fire goo brr styropyro on his shorts channel:i shall teach you everything i know

ah, the drunk crystal

"...Pretty cool, *riiight?"*

Carly: Whatcha got there? Spencer:

Also known as a "drunk goggle" in the wild...

Love your videos man, never stop making em

Give someone a pair of glasses made of this stuff to fuck with them.

That’s gotta be one of the most beautiful examples I’ve seen!

Imagine if they used this on lightsabers

You're smart Keep it up, your videos are pretty cool.

OFFICER: EXCUSE ME, ARE YOU DRUNK?? THIS DUDE: NO, I JUST HAVE CALCITE CRYSTAL VISION

That text effect looked super cool

Just found your channel and I'm addicted lol great stuff man

Looks at calcite: Same

Someone needs to make glasses out of this crystal

This is basically my eyesight turned to a crystal

This thing reminds me of how I used to line up 2 pens or markers in one hand to make my writing have that double effect

Imagine making somebody glasses out of this

My reading glasses must be made out of calcite

I'm renaming this to "the drunk crystal"

They’d be like drunk glasses

Viking sailors used calcite crystals to see the sun and stars over the horizon

Ahh the sun stone

Imagine pranking someone with replacing their windshield with a calcite windshield 🤣

Yoo im shock you didn't say "pretty cool right?"

Good lord those crystals could be used to make drunk goggles

*the empire* "Write that down, write that down!!"

Dyslexic shiny rock

Imagine looking through this while being high

Wait, can you cut that thin enough to make glasses? That means you can be the first person to be the real four eyes...

When you don't say "pretty cool, right?" I don't know the video has ended

You can see the "ATLANTIS" with that

Fun fact Vikings used the calcite crystals to locate where the sun was in the fog

So basically this crystal represents my eyeball without glasses

Wow, those hydrocoptic marsle veins are super bright!

So wait... you're telling me... a DOUBLE RAINBOW??!?!

I accidentally watched this video 15 times because I didn't know it had ended.

This crystal is magically powered by the Foreigner Belt

Natural Astigmatism eh? Nature: Yes

Imagine making glasses out of these

You can get the same effect by getting drunk!

Feels like astigmatism

Would be interesting to see a video filmed through the block
