- Is silica the molecule memes are made of?

Caitlin and Arlo explore a material that may seem mundane and ubiquitous, but is in fact the backbone of our modern telecommunications infrastructure: silica glass. They visit the Diablo Glass School to discover how chemistry plays an important role in the material’s versatility, and experiment with manipulating glass to change its color, and make it so durable that even hammering won’t break it.
But how does this lead to the internet? To find out, they meet with the Exploratorium’s Desiré Whitmore -- also known as “LaserChick” -- who uses lasers to demonstrate how information can be transmitted through glass, and explains how that forms the basis of an ever-growing global fiber optic network than enables high speed internet communication.

This entire channel is so underrated. The quality of your content is almost impeccable.
❤️😌
I love this channel. Feels like I'm a kid at Epcot Center again going through the big dome.
Glass is such a magical substance. I mean, I know, it's science, but it SEEMS like magic!!!! I could sit and stare at those lasers in the water for hours, also - fascinating to see the trapped light.
"Its ok to be smart" send me here and i have to say this is a really interesting video :D
As someone who wears prescription glasses, couldn't agree with you more, I'd probably be dead by now.
Don't some glasses use plastic lenses?
@@kevincronk7981 Yeah that's true, they're usually made of a polycarbonate material (similar to PMMA) nowadays, but they used to be made of glass for hundreds of years.
Being Myopic on the plains of Africa and not being able to detect a large predator, certainly would have weeded out that flaw in modern man. Just as War has weeded out the strong, fit, athletic among us. Something to think about.
Very cool! Thank you for showing a woman of color in material science, Desiree Whitmore, Dr. Laser Chick.
I agree,
I hate the word, "color." It takes away our unique heritage.
If you haven't seen the SmarterEveryDay episode on the Prince Rupert's drop, do it! Destin is awesome at explaining things!
True. So awesome to watch in slow motion.
He has more than one video with prince rupert drops.
And a video in the Lazer-in-water thing.
And the Rupert's Drop Breaker 3 million video on the Hydraulic Press Channel.
I used to love Destin, but I just can't support someone sponsored by Lockheed Martin... Even though they do great work!
Congrats for this awesome video!
Is anyone else a little nervous about the baby next to a forge?
Adam and Jamie did a two part UA-cam series called "the Age of Glass."
Heard they are trying to make it in space, low gravity/0 gravity will be great for creating no bubble fiberoptic cables.
This was totally fascinating.
Thanks!
We taught a rock to think and ever since then we've been paying the price.
Fantastic!
I love Caitlin and alto, probably my favorite duo
Wow glass is freaking awesome love it 🔍🔍🔍🔍🔍🔍🔍🔍🔍🔍🔍🔍🔍🔍🔍.
Yes! More Caitlin~
they forgot to mention cinderella's glass slipper! hmphft!
Love ❤ it. Thanks for sharing
Lol, In the country our houses are too far apart so all that is available is Hughes net which is expensive and slow. So it's pointless in the rural areas
How does information don't mix up with the others on single core fibre optic cable?
Oka, so the lesson is that we have to worry about the internet's future since everyone knows sand is becoming a commodity and that scientists will now have to become creative
loved the video though
This is so fucking COOL
Dr laser chick reminds me of the girl from “atypical”
Whenever I didn't have signal on my phone, I would put it against our glass patio door. I knew it gave me signal but I didn't know why.
3:47 Jingle bells, jingle bells
Hahaha. It was the right rhythm at least.
@@VeteranVandal :D
Why is the speed of light lower in air than in vacuum?
Because of a property called the index of refraction. The speed of light changes as a function of the material it is traveling through, and also as a function of the color of the light. It is the same property that causes white light to form a rainbow inside of a prism.
This video explains, Martyn: ua-cam.com/video/mICTVow3-3I/v-deo.html.
So what do we do when we run out of sand?
Is light made of particles or is it a wave... ?
8:40 This statement doesn’t exactly clarify what sizes and resolutions those two decades of movies are being transferred in.
Hi! Sorry this response took so long, lol. We included a description on screen where we assume that the films are in HD and approximately 6GB in size.
technically glass makes your internet slower. it just gives you more of it.
not true. yes it does make it slower but it doesnt give us more of it. it gives us the ability to direct it instead
glass is NOT between a solid and a liquid. it is 100% a solid
Hiya! Arlo here. Glass is considered to be an amorphous solid, which is a state somewhere between those two states of matter.
Why does an educational channel use Fahrenheit, miles and other unscientific units of measurement?
Because America.
To cater to probably like 70% of their audience?
@@ritwikism Is it really then an educational channel if you choose to cater instead of educating?
Nice mullet joke
Plz make videos with the aspect ratio 20:9
Fluffy. Unfocused.
So Caitlin is pregnant.

@@caitlinsaks4910 wow congrats!
2:07 Editing that lady onto his laptop while Arlo pretend-talked was such a cheesy unnecessary addition to the video lol
Well done. You finally made a video without pushing an agenda!
