My relationship with math is like with an ex: I don't know why I want to understand her, but I always come back.

Matrices are movements of space

Grab the red or green arrow and drag. The whole grid moves with them. This is linear algebra, and you will realize you get it in a minute.

Start with the first lesson
Playground: move space
î = (1.00, 0.00)ĵ = (0.00, 1.00)square area = 1.00

Who this is for

You're curious how the math behind AI works, but a voice in your head says: I'm just not a math person.

I'm not either. Math never came naturally to me. I'm learning it now together with you, step by step, and I write it the way I'd want to hear it: no unexplained definitions, and pictures you can grab with your hands.

If I can get it, so can you. "Dumb" is just what we think of ourselves until we understand.

Where we're going

Four tracks, each building on the last. I'm learning them together with you, so I write the explanations the way I'd want to hear them.

  1. Linear algebra

    Vectors, matrices and what they do to space.

    3 lessons ready, 4 more soon

  2. Calculus

    Derivatives and gradients: how to know which way to go.

    In preparation, 3 more soon

  3. Probability

    How to calculate with uncertainty.

    In preparation, 3 more soon

  4. Machine learning

    Everything above, put together.

Colors tell you what matters

Every block type has its own color and its own shape. If you get lost in the text, just look for the yellow star.
