## Intuition for Slope-Intercept Form

Slope-intercept form is written in a very mathy way: y = mx + b. Let's turn this into plain English.

## Learning Math: Find The Implied Subject

In English, we often drop the subject of a phrase, such as in these signs:
Who are these signs written for? It's really *You, stop* or *You, yield* or *You, be alert for bears* (I'm not doing it).
After internalizing a language, we can take hints without explicit instructions. But, to put it politely, math isn't usually well-internalized.
Let's get clear about who the "math signs" are referring to.

## The Lesson and the Meta-lesson

In class there's the lesson about a specific formula, sure, but the meta-lesson is how well the experience went. What worked? What didn't? How can we get more of the first and less of the second?

## Math and Analogies

Here's a talk (video and transcript) on "Math And Analogies" I did for the Center on Contemporary Art in Seattle. The gist: good analogies make math a joy.

## Einstein’s Theory of Special Relativity (MetaLearn Podcast)

I had another great chat with Nasos Papadopoulos on the wonderful MetaLearn podcast. Einstein’s Theory of Special Relativity has many consequences, including the famous equation E = MC² (Energy = Mass x Speed of Light²) and the notion that space and time are relative (observers can have different experiences of how large something is, or how much time elapsed).

## Quick Insight: Intuitive Meaning of Division

While working on some math colorizations I ran across some interpretations of division.

Multiplication can be repeated addition, scaling, rotating (via imaginary numbers), and more.

What about division? Let's take a look.
