Your next house could be built with dirty diapers

0:03 Caloroga Shark Media. Hello, I'm Choinning Mack with five good news stories. Sciences are pumped. They have discovered a new shape. It's a new Einstein shape, a thirteen sided shape called the hat. Lots of copies of the shape can be used to cover a flat surface without ever overlapping or leaving any gaps. Also, the patterns never repeat. Mathematicians have been looking for shape like this for fifty years. They call it an Einstein. It doesn't have anything to do with Albert Einstein, though. Huh see, I thought the same thing. I was stricked as well. Einstein means one stone in German, and in this case, Einstein means a single shape that doesn't cause repeating patterns. I bet a lot of people will get that wrong in the future.

0:51 Good trivia question, isn't it? Yes. In fact, I'm going to take that and use that as one of the questions. We have a new podcast. It's called five Daily Trivia Questions. I'm gonna throw that in so when that shows up, you'll know the answer. If you look at most tiled patterns, you'll see that the pattern pizza after a while, But this one no. In nineteen sixty one, one mathematician suggested there was no way to cover surface without tiles without creating a repeating pattern. That person obviously wrong. Then his student created a set of tiles that didn't create a repeating pattern, but there were twenty four and twenty six shapes in that set. Later, the same student got the number down to one hundred and four shapes. In the nineteen seventies, mathematician Roger Penrose found two shapes could cover a surface with no repeating pattern. Last November, David Smith discovered it could be done. How does it work well? First, they figured out that the hat shapes can group together to form a bigger shape called a metatile. The metatiles can then form even bigger shapes called supertiles, and so on. Since the medatiles, supertiles, super supertitles, etc. Never repeat, had is able to cover any flat surface without repeating. Smith later found a second Einstein shape. He calls that one the turtle, But careful study showed that both the hat and the turtle belonged to a family of similar shapes that could be created by slightly changing the sizes of the hat. By studying the different shapes in the family, experts prove that the hat could never form a repeating pattern.

2:15 As for the turtle, still needs to be double checked by experts. So before you rush out and tile your whole house in turtle shapes and then start bragging your friends, might not be true yet. Petra Jenny has a nineteen seventy three Cherokee Piper airplane inside creates to hold seventeen dogs. Petra's flying the dogs to turn them over to Laura LaBelle, co founder of the LaBelle Foundation Rescue in Los Angeles. Petra's helping to move the dogs around because a lot of shelters are full. There are also some buses who take bigger dogs up to Washington State. Some donors are paying for chihuahuas to fly to Connecticut. As for Petra, she operates Amelia Air and all volunteer nonprofit animal rescue organizations she found in twenty nineteen. Private pilots need regular flight hours to maintain their licenses, so why not put all that time and expense towards a mission.

3:02 See that's super smart. Amelia Air has rescued thirteen hundred dogs, cats, and even a few ferrets. She herself has two eleven year old pit balls at home and no space for any more dogs. She says, if I took home every dog I transported, I couldn't fly anymore. Daniel Dorik has a pottery studio in his single car garage in Echo Park. He started this as a social media experiment on Instagram. He said, I had thirty vases sitting in my garage and I decided to throw them up on my personal Instagram account. I sold three thousand dollars worth of pottery in half a day. He ended up spending seven hundred dollars to ship the vasis because he didn't know what he was doing at the start of the business. Following the surprise success of the Instagram sale, he quit his downtown La hotel job spent two weeks in Mexico City, where he created a business plan with the help of a friend. He made a website, a logo on branding, and he set up Danny D's Mud Shop and his Echo Park garage the slogan turning mud into really nice ceramics. He jokes, I left my forty hour week job to work ninety hours a week. I feel you. Meanwhile, in Ventura, eight months after her husband Chad was diagnosed with stage four lung cancer.

4:05 Stacy planted eleven hundred flower seeds in her backyard. She said something called me to do it. I needed a sanctuary. They were already growing vegetables and tending to a flock of free roaming chickens and three cats, and dreaming of building an urban farm. Chad said he's grateful that Stacy can walk outside and tend to her flowers if his mood turns dark, especially when his depression becomes overwhelming some days. Stacy says, there's resilience seeds he plants. It's a language in itself. Stacey had no gardening experience and says the biggest thing was taking the leap of faith by reading the back of the seed packet and trusting the process. It's easy to get caught up in all the planting logistics and never get started with it. Chad says cancer has taught me that people are good. I appreciate people more now than ever before, and I give a lot more hugs. Good news. I've got a solution for all those dirty diapers you've got. We're gonna build a house. Yeah no, really.

4:57 A group of scientists from the University of kid a qu in Japan have come up with a solution. You see, concrete is one of the most common building materials in the world to use to construct many things roads, sidewalks, buildings. It's usually made by mixing together sand, water, and cement. But what if we didn't have to mind for the sand. What if we took dirty diapers and use them to replace the sand. In the US alone, over eight billion pounds of dirty diapers and thrown away eg here. So the scientists collect them, used diapers, clean them up, treated the diapers with chemicals to get rid of any bad germs. The diapers were dried and shredded into small pieces that could be added to concrete. They found diaper concrete is just as safe and strong as a regular concrete. It also doesn't have any harmful germs. And they point out sand needs to be mined, which costs money. Use diapers are basically free and there's no shortage of them.

5:51 You know someone's going to turn this into a business and actually make money off dirty diapers. Just give it some time. I trust innovators. And that's your five good news stories for two day. If you enjoy the program, tell a friend about it. They might like it too, and you have a great day,
