About The Scientist Lounge
What is this?
The Scientist Lounge is a collection of free, interactive science simulations that run directly in your browser. No downloads, no accounts, no paywalls — just science you can play with. The site currently focuses on physics, with plans to expand into chemistry and other disciplines.
Why it exists
Science is easier to understand when you can see it in action. Textbook diagrams are static, and videos only show one scenario. Simulations let you change the variables yourself and watch what happens — building real intuition for how the world works.
The Scientist Lounge was created to make that kind of hands-on exploration available to anyone with a web browser. Every simulation is designed for students, curious learners, and anyone who wants to understand the science behind everyday phenomena.
What you'll find here
- Interactive simulations — currently covering Newtonian mechanics (projectile motion, collisions, pendulums, springs, and more), with new topics and disciplines added regularly.
- Companion articles — each simulation has an article explaining the science behind it, written for a high school to early university audience.
- Real-time readouts — every simulation shows live values for velocity, acceleration, energy, and other quantities so you can connect the math to the motion.
How it's built
The entire site is built with vanilla JavaScript, HTML, and CSS — no frameworks, no external libraries. The simulations render on HTML Canvas 2D with accurate physics integration at 240 substeps per second.
