We built an interactive 3D module to teach kids about what temperature does to water. - You adjust the temperature in real time - You see the impact on the state of water and what's changing at a molecular level - You can unlock two secret states in there... show more

Following the amazing reaction to the Marble Curriculum yesterday, we've decided to make it open source 🛰️👇 Everything a child learns in primary school. 1,590 concepts. 3,221 connections across 8 subjects, from Math and Science to Computing and Life Skills. Anchored in the US and UK curriculums, standard by standard (NGSS, Common Core, DfE). What you will find in the repo: every concept as structured JSON with its age band and the evidence a child must show to master it. Every prerequisite link marked hard or soft, with a written rationale. It's a true DAG you can compute learning paths on. Open license, you can build whatever you want with it. Now is a unique time in history to be building in education. Getting AI and kids education right is likely one of the hardest and most important problems to crack over the next decade and we need as many smart and creative minds behind it. We think a common solid basis, accessible to all and that can be built upon, is critical to move fast. That's why we're making this curriculum open source. It's not perfect but we know it's a robust basis, and we believe that sharing it openly is the fastest way to progress in this field. If you're building in education, share this around you and tell us in comments if you find this useful and if you want to contribute. We'll keep working and investing on it Marble App. Credit goes to Guillaume Boniface-Chang for building this. I just made it look pretty. Links below 👇

WATCH: EFF in the City of Tshwane metro hands a glass of Hammanskraal water to the Speaker of council. "You are saying there's no cholera. Drink that water! Let's see if you wake up in the morning"

You can now run real-time water simulations at this level of quality directly inside Unreal Engine 5.5 with the built-in Niagara Fluids. Learn my entire workflow for detailed water sims - link is below.

Vance: Absolutely, by all means, let's take down the temperature, but if you want to take down the temperature and you are on the left of center, the first and most important thing you can do is look in the mirror.

There is a "flash" bug in the One UI 7 Beta1 animation. In fact, there are at least three versions of this problem. Samsung seems to have not found it, so it has not been solved. You only need to open two apps in succession a little quickly (not particularly fast)，You will see a quick flicker in the picture. The first video is played at normal speed, and you can see a flash picture. The second video is a slow video, and you can see the moment when the soul of a page flashes in the ninth second. I call it the One UI 7 haunted event.

There is a bike trail in Belgium where you can go "Cycling Through Water," through a large lake. This bridge is below the water line and in parts it is low enough to put riders at eye level with the lake.

Octopuses can grow at different rates depending on the water temperature. You can find 3-month-old ones which are at the size of a quarter and some 1-week old at the size of a fingernail. But when first born, an octopus is only about the size of a pea

Alright then. Are we doing another one of these for 2023 or what? #readingfc (Reply “IN” if you want to see the fixture on the calendar this year)

The ATG School One-Pager I’m not trying to reinvent schooling. There are just a handful of things I believe in which I haven’t seen in any school I’ve been around as a student or parent. Policy #1: Each student gets to be responsible for growing some of their own food, no matter how small, and THROUGHOUT schooling (not just a quickie project here or there). Policy #2: Minimum 1:1 ratio of time NOT SITTING IN THE CLASSROOM. What you do with this is up to you. There are so many real world skills, sports, gardening, music, etc. The strict ratio in the school day is the key for me. Common sense and personal interests can take it from there. Policy #3: Daily time to read whatever you want to read about. The biggest barrier for my reading was INTEREST. Be there to ensure the book is at their level, and to help them if they don’t understand something. Other than that, LET THEM ENJOY READING, ALL THE WAY THROUGH SCHOOL, not just in early years. Policy #4: (This is the most unusual yet the biggest reason I’m in education.) High school is a 50/50 bridge to winning in real life. Mornings are for actual work, making and SAVING UP MONEY. Afternoons are for learning finances and professional skills of YOUR INTEREST. With average work, you’ll finish school with $50,000-$100,000 in the bank, more skills than the norm, and a greater chance of creating your life and work from there on out, rather than conforming to make a paycheck. Policy #5: As part of the high school 50/50 system, ensure each student learns the adult financial red tape in your state/country before you’ve got bills, kids, etc.

I’m trying to prove a point! If you’re a Republican seeing this, let me know in the comments if you hate gay people. If you’re a gay person seeing this, go to the comments and see what people are saying. It might surprise you!

This entire club at a public school in California gave their lives to Jesus! Did you read that? Over 350 students during school hours said yes to the Lord. We are in the beginning stages of awakening in the United States of America. If you’re more aware of tucker Carlson and Candace Owens than you are the kingdom of our God it’s time for a reality check. We are living in one of the greatest moves of God on this side of eternity! Do you believe it?

There’s a livestream of the billboard and you can see the message up there every hour today on the 45 minute mark (the next one will be up at 10:45am BRT) or if you are in NYC you can go in person 🧡

Here's an excellent video from Florian (follow) that shows charged water on the left and neutral water in the right. This is a visual confirmation of two known effects; Electrostatic induction and dielectric relaxation time. Electrostatic induction is like when a hair-rubbed balloon sticks to the wall, despite the wall being neutral; the balloon causes charges in the wall to polarize so the wall side near the balloon turns negative and the other side of the wall is positive. That's electrostatic induction and that's why you have raindrops that stick to a car window for hours of wind and gravity, rain has a small negative charge. Wouldn't work with tap water. Now, if you remove the balloon, the wall doesn't return to a neutral state immediately. It'd happen quickly if we had a balloon on the other side of the wall, but by itself this can take seconds, minutes, hours or even days, depending on the material and thickness. Glass is quite slow, and you can see the electric forces holding each other will hold off gravity for some time; and that the water greatly prefers not to be broken off, water is like an uncountable number of those walls in series, and they all cling to each other in proportion to how many balloons we have, ie how many excess electrons we have. Furthermore, when the water is extremely charged, it will not even leave the thin remnant layer of water that trails behind, as the cohesive internal forces outweigh those by induced to outside neutral surfaces.

Seems like a lot of you are excited about Wave Link 2.0, which is really cool! 🫶 Two more features that are worth calling out. The first is simple but just really nice. If you rename an input in Wave Link, the name of the virtual device you see across Windows will also be renamed. Second - you can now set up a Stream Deck action that automatically adds the foreground app to a pre-defined Wave Link input. Kind of a magical way to configure audio routing, especially with the new app grouping.

UPDATE: All heavy duty pumps, and associated system components at the Katosi water works are in action. We are pushing water to Kampala at FULL BLAST, and some customers have started receiving water. For those without water, help is on the way. We are rigorously charging the network with water in a bid to serve you in the shortest time possible. #waterman Dr. Silver Mugisha
