Dedicated to Nissan Native, my teacher.

Nissan Native — theatre, science, and the line between matter and life

He taught me acting, theatre, drama, how to handle text. How to stand in front of people and mean something.

Neither of us knew, I think, that he was also teaching me science.

He elevated my quality of thinking. He taught me to observe. To be rigorous. To be specific. To reflect without fear and without judgment. To see things the way they are - not the way you wish them to be, not the way the room expects them to be.

And most important of all, he taught me this:

The only way to define a character is by its selections under constraint.

That sentence is everything.

It doesn't only apply to characters in a play. It applies to all things in the universe.

A magnet is a magnet because it attracts iron. It is matter, and it cannot select differently. It yields. It has no choice. Physics moves it and it goes.

A bacterium rejects poison and moves toward glucose. Not because physics pushes it. Because it selects inputs for continuation. It filters to continue.

That is the line between matter and life. Not composition. Not complexity. Selection under constraint — for self-continuation.

You don't need mathematics for this. You don't need complicated calculations.

Math and calculation come after insights, they support insights.

But first...

You just need to observe.

Nissan taught me to observe a character until it revealed itself. I never stopped.
