1 · Think first

A computer doesn't know letters — it only handles numbers. So it turns each word into a bundle of several numbers and works with that.

They aren't just any numbers. It learns to give similar numbers to words that get used with similar words, so words with close meanings land in close spots.

Once meaning becomes a place, you can measure near and far with math. That's the base for tomorrow's lesson, finding similar things.

2 · Experiment · Split it up

Try it — Switch words' pieces of meaning on and off

Let's pretend each word is a bundle of seven boxes of numbers. Tap a different word to see which boxes light up. The more lit boxes two words share, the closer they are.

Seen as letters vs seen as number bundles

Same word — but what you can do with it depends on how you store it.

As plain letters'dog' and 'puppy' are total strangersDifferent letters, different wordNo way to measure how similarAs number bundlesSimilar meaning, similar numbersNear and far can be measuredCan guess combos it's never seenPeople don't set the numbers. While reading a huge amount of text, it adjusts themitself so that words used with similar words get similar numbers.Key idea: turn meaning into places, and you can calculate near and far
The famous example 'king minus man plus woman lands near queen' also comes from this sense of place.
