Words as Numbers.
Watch words become vectors in space — and discover that math can capture meaning.
After this lesson you'll know
- How words become vectors (lists of numbers)
- Why similar words cluster together in space
- The famous king - man + woman = queen equation
- Why embeddings are the foundation of modern AI
The Big Idea
Words have coordinates in a universe of meaning.
AI cannot read words. It reads numbers. So every word gets converted into a list of numbers — a vector — that captures its meaning. "Cat" might be [0.2, 0.8, -0.1, ...] across hundreds of dimensions.
The magic: words that mean similar things end up close together. "Happy," "joyful," and "delighted" are neighbors. "Sad" is far away. The space itself encodes meaning.
