Wow. What did I just see? Wonderful and so satisfying. Interesting to see that some plants are tiny above ground compared to their existence below ground - plant-cartels :)

I always suspected that rivers are like trees - they also might have a hierarchy of streams (root system) inside the sea. Sometimes this root system is exposed to above "ground" in the form of deltas and streams around them.

They usually are. It’s a process akin to archaeology where they have to carefully wash away the dirt from the root system, measuring as they go. The problem with this method is that it's hard to reconstruct the entire 3d structure of bigger plants like trees so a lot of the root drawings on the site don’t accurately show how deep they go. It’s much easier with small plants where the researcher can control the soil us…

I had assumed they had grown the plant between two vertical, parallel panes of glass.

That would probably produce a distorted image of the root system.

I thought it'd be about Lie groups! https://en.wikipedia.org/wiki/Root_system

The context of HN is interesting. We see the word “root” and immediately assume it has to do with a filesystem or math… but not actual, physical roots haha

Or other math! https://en.wikipedia.org/wiki/Root_of_unity
