This is Algebrica, a mathematical knowledge base I've been building since May 2023, primarily for university students. 306+ entries, carefully written and structured. Over 4.2 million views since its launch (not much in absolute terms, perhaps, but meaningful to me). No ads. No courses to sell. No gamification. No distractions. Built simply for the pleasure of sharing knowledge. All content is licensed under Creative Commons (CC BY-NC 4.0). Every article, text, and illustration is freely available and downloadable in editable formats, including Markdown and SVG. Free to access. Free to learn. Free to share. If you believe mathematical knowledge should be freely accessible to everyone, explore Algebrica, use its resources, share them with others, and help this project reach more people. algebrica.org

I was strongly opposed to lecture recordings for much the reasons given here until I received a note from a student with extreme dyslexia, for whom being able to replay short segments of a lecture multiple times had revolutionised his learning. He did very well in his degree.

We were taught that Earth orbits the Sun in a closed circle. In reality, Earth has never returned to the same point in space once in 4.5 billion years. ​Right now, the Sun is carrying Earth and every planet around the center of the Milky Way at 230 km/s (828,000 km/h), more than 18,000 kilometers every 80 seconds. ​Because the Solar System is tilted 60.2° to the galactic plane and bobs up and down through the galactic disc roughly every 30 million years, the planets trace open 3D corkscrew helices across deep space rather than flat loops. ​The last time the Sun stood where it stands today, one Galactic Year (230 million years) ago, the very first dinosaurs were only beginning to appear on Earth. Since forming 4.6 billion years ago, our Sun has completed only 20 laps.

Seems like a lot of people could use something like this. So I polished it overnight and added Calculus, multi-language support, and hundreds of AP-level questions with matching animations to test your understanding. Also got a domain for it: atlasclass.app As a visual learner, this was the most intuitive way for me to learn, and it’s extremely fulfilling to see so many others feel the same. Will add more subjects when I get the chance!

Memorization has an unfairly negative reputation. I recently spent a few hours memorizing the names of all the countries in the world and it's such a clear improvement in how well I can understand and reason about other topics. Memorization is scaffolding for more complex ideas

Things that aren’t there can now see and hear you. Reality-Aware Rendering is now live in Simulon. Place anything in the real world, act out the scene, and it responds to you. We made this short in an afternoon. Watch to the end to see what was really there. Available now on iPhone. How it works 👇

this is the most american thing i've ever seen

You mean to tell me that I can buy a watch for only $850 and it looks better than a Rolex.

Wow. 🏆

The owner of that website is clearly trying to show something, that the media (who only learned of PHP's existence a few days ago), have overstated the risk of this issue. It's a genuine vulnerability but actual exploitation risk is low due to nuances.
