Learning physics through functional programming encourages students to think about the "what" rather than the "how." By removing the overhead of memory management and mutable state, the student is left with the pure logic of the universe. This methodology not only produces better programmers but more rigorous physicists. A physical state (position, velocity) can be defined
type Vector = (Double, Double) type State = (Vector, Vector) -- (Position, Velocity) applyGravity :: Double -> State -> State applyGravity dt ((x, y), (vx, vy)) = let g = -9.81 newVy = vy + g * dt newX = x + vx * dt newY = y + vy * dt in ((newX, newY), (vx, newVy)) Use code with caution. type Vector = (Double, Double) type State =
