Learning AI in public

First Principles AIfrom vectors to transformers.

This site is a living notebook of my journey from physics to AI engineering. Every post is built from first principles: start with the math and intuition, then layer on code and projects.

Start here

  1. 1. Read the three core math posts: vectors, dot product, chain rule.
  2. 2. Follow the gradient descent series to see optimization as geometry.
  3. 3. Play with the matrix mixing demo under Math for AI.
  4. 4. Move into neural networks, backprop, and deep learning projects.
