This track follows the Feynman Lectures chapter by chapter. Each lesson is made of steps, each with a simulation and questions to think over, and there are no exercise lists. The original text is on the Caltech website, and it is worth reading alongside.
From Dennis's blocks to E = mc², by way of reversible machines, Stevin's chain and the pendulum.
From Galileo's pulse to the size of the nucleus, by way of the day, the pendulum, atomic clocks and the triangulation of the stars.
From dice and coins to the random walker, the Gaussian curve and the electron cloud: how far a result can stray from what we expect with nothing being wrong.
From Kepler's ellipse to a force that falls as 1/r², tested on the Moon, in double stars and on a torsion balance, up to the point where Newton is no longer enough.
From a car on a straight road to a falling ball and a launched projectile: velocity as the slope of a curve, distance as the area beneath it and acceleration as the derivative of the derivative.
