Bottom Up

The paper by Thierry and Thierry presents a Lisp solution to a data and program problem. In "Dynamic data models: on application of MOP-based persistence in Common Lisp."

The Meta Object Protocol (MOP) of Common Lisp allows to produce a data system which evolves according to requirements. One important concept here is persistence. States have to stay, even if unexpected events force a shutdown of the system.

Lisp is used for artificial intelligence, the structure of products in this language is simple in the beginning. The building blocks are simple, and it can get more complicated as it adapts to new requirements. This is the bottom up approach.

When I started to work on my Physics research, I felt that Information was part of nature, but I did not know how. I believe now, that more than Information, what we have for interacting systems is In-formation, as in the autopoeitic ideas I have been presenting in this blog. That is to say, the rigid concept of Information in Cybernetics, comes from the robot part of the discipline. Engineers have to specify beforehand what they are going to do: [;\tau \epsilon \lambda o \sigma;], purpose. Living things, and I believe, most things in the Universe, do not have the luxury of hindsight. Therefore the key concept is fit. One new part, has to fit with the bottom part. We end up with a bottom up Universe, and a bottom up language is welcome, for us to understand, what is outside of our heads.

In the end, I believe, a bottom up solution, is not enough. The reason is that other systems are also building and maintaining themselves in the bottom up way, at some point, not a top down effect, but more of a peer to peer, scheme has to operate.  That will be a subject for another note. Here I say that a bottom up language program, that makes programs, can be a good model for the structure of Mechanics, because, for instance, the Solar System is organized with a central center, the Sun, and then planets, moons, and other small objects, can be calculated on the basis of what everything else has produced, the structure of the Solar System. Maybe the local character of Gravity is enough for this hierarchy.
