Physics Through Simulation
Discover how computers solve the mysteries of the universe using simple logic instead of complex equations. Rebuild your confidence in science by learning to think like a digital physicist.
Like Duolingo, but for Physics Through Simulation. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
21 levels across 4 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through A New Way to Learn, The Logic of Motion, Systems and Complexity, and Your Future in Physics. It starts from scratch.

Key ideas in Physics Through Simulation
- Your brain already predicts physical outcomes like trajectory and impact
- Math symbols are just 'nicknames' for physical concepts like 'change in speed'
- Computational physics is the process of translating these 'gut feelings' into explicit steps for a machine
- The logic of physics exists independently of the notation used to write it down
- Intuition about how objects move is more fundamental than the equations used to describe them
- Computational physics focuses on the logic of the relationship (e.g., 'pushing harder makes it go faster') rather than the Greek letters
- Recognition that physical intuition is the foundation of computational modeling
- Understanding that math symbols are just a shorthand for physical relationships
- Reframing a lack of math background as a benefit for algorithmic thinking
- Understanding that computers solve complex physics through simple arithmetic
- Visualizing the physical behavior is the first step in building a simulation
- The 'why' (physics) must be understood before the 'how' (code)
- Coding is merely the final translation of a concept you already understand
- Prioritizing conceptual understanding over technical implementation
- Computers calculate motion in tiny 'time steps' rather than one big jump
- Simple addition and subtraction can replace complex formulas if the steps are small enough
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Physics Through Simulation the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
