+Maybe every problem can be translated to geometry (use any shapes and
+as many dimensions as you need). Solution(s) to such problems would
+then appear as relatively simple search/comparison/lookup results. As
+a bonus, such geometrical *data storage* AND *computation* can be
+naturally made in *parallel* and *distributed*. That's what neurons in
+the brain appear to be doing ! :) . Learning means building/updating
+the model (the hard part). Question answering is making (relatively
+simple) lookups (geometrical queries) against the model.

+ :END:
+Object oriented programming is inspired by the way human mind
+operates. It allows programmer to express ideas to computer in a more
+human-like terms.
+
+It is possible to map object model to geometrical hyperspace:
+
++ Object is a point in space (universe). Each object member variable
+ translates to its own dimension. That is: if class declares 4
+ variables for an object, then corresponding object can be stored as
+ a single point inside 4 dimensional space. Variable values translate
+ to point coordinates in space. That is: Integer, floating point
+ number and even boolean and string can be translated to linear value
+ that can be used as a coordinate along particular dimension.
+
++ Each class declares its own space (universe). All class instances
+ (objects) are points inside that particular universe. References
+ between objects of different types are hyperlinks (portals) between
+ different universes.
+** Handling of relations
+ :PROPERTIES:
+ :ID: b6b15bd2-c78b-4c51-a343-72843a515c29
+ :END:
+Consider we want to create database of books and authors. Book can
+have multiple authors, and single person can be author for multiple
+books. It is possible to store how many hours of work each author has
+contributed to every book, using hyperspace as follows:
+
++ Every dimension corresponds to one particular book author. (10
+ authors in the database, would require 10 dimensional space)
+ + Point in space corresponds to one particular book.
+ + Point location along particular (author) dimension corresponds
+ to amount of work contributed by particular author for given
+ book.
+
+Alternatively:
+
++ Every dimension corresponds to one particular book.
+ + Point in space corresponds to one particular author in the entire
+ database.
+ + Point location along particular (book) dimension corresponds to
+ amount of work contributed for book by given author (point).
+
+** Layered architecture
++ layer 1 :: disk / block storage / partition
+
++ layer 2 :: key/value storage. Keys are unique and are dictated by
+ storage engine. Value is arbitrary but limited size byte
+ array. This layer is responsible for handling disk
+ defragmentation and consistency in case of crash
+ recovery.
+
++ layer 3 :: key/value storage. Keys are content hashes. Values are
+ arbitrary but limited size content byte arrays. This
+ layer effectively implements content addressable
+ storage. Content addressible storage enables GIT-like
+ behavior (possibility for competing branches, retaining
+ history, transparent deduplication)
+
++ layer 4 :: Implements arbitrary dimensional multiverse.
+
++ layer 5 :: Distributed computation engine.
