Understand physics, not just formulas.
From kinematics to quantum mechanics — build real intuition with visual lessons, guided problem sets, and simulations you can play with.
Courses for every level
Structured paths from first principles to advanced topics, each with labs and problem sets.
Classical Mechanics
Kinematics, Newton's laws, energy, and momentum through interactive problem-solving.
Electricity & Magnetism
Fields, circuits, and Maxwell's equations, visualized with live simulations.
Quantum Mechanics
Wavefunctions, uncertainty, and quantum systems built up from the ground rules.
Thermodynamics
Heat, entropy, and statistical mechanics with real-world engineering examples.
Waves & Optics
Oscillations, sound, light, and interference explored through simulation labs.
Relativity & Cosmology
Special and general relativity, spacetime, and the large-scale structure of the universe.
Built for real understanding
Physics is learned by doing. Every concept here comes with something to manipulate.
Guided Problem Sets
Step-by-step problems with instant feedback and worked solutions.
Live Simulations
Adjust variables and watch the physics respond in real time.
Study Groups
Work through modules alongside peers with shared progress tracking.
Exam Prep
Aligned practice sets for AP Physics, A-Level, and intro university courses.
