There’s a kind of experience that’s category-less. There’s no past or present or future. There’s no was or will be or is. There’s no there or here. It lacks a category and when people leave that experience and try to explain it to others, it comes out crazy, not because it’s crazy but because human language with their tenses and object-ness don’t have the capacity for it without sounding alien.

Here is an operational definition of what “2D Materials” means. [it’s a phrase that goes together, 2D as a qualifier for Materials]. This can be distinguished from “2D Geometry”
” But, before going any further, in order to clarify concepts, an operational definition of a 2D material is required: in this review we understand 2D materials as those that do not require a substrate to exist. In other words, they can be isolated as freestanding one atom thick sheets. This definition can be relaxed to include materials with a thickness of a few atoms (less than 10).”

So you’re talking about “2 dimensional SHAPES”.
This is about “2 dimensional MATERIALS”.
Shapes =/= Materials

I mean to say “2D” doesn’t mean anything much by itself. It’s 2D-What – there has to be a “something” that is 2D.
