A photo is a single point in a space with three million dimensions.
F1 · Numbers That Learn
Every model you will ever build touches only lists of numbers. Here those lists become arrows you can drag, and matrices become machines that bend the space the arrows live in. You will feel why a dot product is a similarity score, why length matters, and what one layer can and cannot reach. Then the chapter turns the lights on in a space with twelve thousand dimensions, where everything is far from everything and almost every pair of directions is square to the other. No formula is needed to follow any of it.
