I started teaching my daughter physics by showing her how things actually work - plucking guitar strings to explain vibration, mixing paints to understand light, dropping objects to see gravity in action. She learned so much faster through hands-on exploration than through books or videos. That's when I realized: what if I could recreate these physical experiments as interactive simulations? Lumen is the result - an interactive physics playground covering sound, light, motion, life, and mechanics. Each module lets you manipulate variables in real-time and see/hear the results…

I didn't realize Universe Sandbox ran on MacOS, and I was in the mood to play around a bit. Some functions it's got: - Random system generation - Sonification is super fun too - Habitability Simulation (Just for fun, don't cite this please) - Replacing, spawning, deleting objects I've had tons of fun building this, so I hope someone else can share the joy. It's free and runs in the browser. I'd love to hear any feedback. I think this is at a state where I might leave it as it is, but if people are interested in other features, maybe I'll keep working on it. I've kept saying I'll stop working…

There’s a really good kids’ science magazine called Oyla, but it’s aimed at kids 12+ I subscribed a couple of years ago thinking that it would be fine for my son (then 8yo, but an advanced reader) but, even now (10yo), the articles are too dense for him and don’t hold his interest. Last year, the same company launched ‘Oyla Junior’ aimed at younger kids ~8yo. But I read a couple of the articles and I think they’re too oversimplified. I wanted something in between, but didn’t find anything suitable online. So I used AI to create something, and did a bunch of iterations to tune the sentence…
