Cantor sees a set as a 'collection into a whole' of 'objects of our thought or our intuition.' If we consider our observable environment to comprise ℵ0 events (we can always find one more), there are ℵ1 ways of selecting subsets of these events and ordering them. What science seeks to do is to select out of these possible
[page 197]
orders the ones that are actually realized, and give the observed connections and orderings.
Since sets are indifferent to size we can use them to construct structures of any size.

Replace the billiard ball paradigm with the network paradigm. This implies replacing cardinal continuity with logical continuity.
The endgame. : finally breaking free of the apologetic scaffolding of my opposition to Christianity and moving toward a freestanding picture of the divine world. An interpretation of the standard model need make no mention of theology, dealing only with universal Turing machines in a network.
1. Map network to quantum mechanics = function space
2. add special relativity <- why quantized
3. Add general relativity <- bandwidth, energy
4. Add meaning (unary --> binary) optimization and Lagrangian +
scale invariance.

Universe is inherently dynamic (unlike text) so physics requires a time dimension. The introduction of space 'breaks the symmetry' of the time dimension, so [creating] many different proper times (mine, yours, etc) which are 'spatially' separated.
Peacock page 3: '[Special relativity] is an elaboration of the intuitive point of view that the properties of empty [? inertial] space
[page 198]
should be the same throughout the Universe.' Peacock In fact there is no 'empty space', space and the 'content of space; are divisible in thought but not in reality. Lonergan
Peacock page 4: 'Despite the mathematical complexity that can result, general relativity is at ear a highly intuitive theory: the way in which everyday experience can be generalized to deduce the large scale structure of the Universe is one of the most magical parts of physics.'
The relativistic 'interval' dx is an 'infinitesimal' and so a mathematical artifact. In reality (let us say) there must be some 'unit' of distance which in information terms is something like Hamming distance.
Things are simple in the rest frame
"the only valid physical laws are those that equate two quantities that transform in the same way under an arbitrary change of coordinates, ie physics abstracts from meaning. Peacock page 4.
Gravitation only becomes observable when some other force exists to push us off our geodesic.
Einstein: inertial force gravitational force.
page 7: 'the important aspects of gravitation are not so much to do with first-order effects as second order tidal forces.: these cannot be transformed away and are the true signature of gravitating mass.'
GENERAL COVARIANCE - ABSTRACTION FROM MEANING
[page 199]
INCONSISTENCY = ERROR
THE UNIVERSE IS CONSISTENT = ERROR FREE
The big issue for me is finding the optimum balance between freedom and control. I think this optimum is enshrined in the physical world and is captured by the stationarity of the Lagrangian. We might imagine that these stationary points are moved to new eigenvalues by the discovery and propagation of algorithms.

From a simplification point of view, the initial state of the Universe might have obeys Bose statistics and we could say that un the initial singularity all the energy f the Universe is concentrated in one state of frequency Eu / h.

{AXIOM} = alphabet of a process.
Metric continuity vs logical continuity.
Violence occurs in incomplete spaces when the point to which people want to converge is not available to them, eg free love in the Roman Catholic Church.

COMMUNICATION --> CORRELATION
The degree to which two states are correlated is measured by the inner (dot) product.
Just like the ancient models of the world proposed by Moses, Plato, Aristotle and Aquinas, the standard model is invisible to use and has been constructed to explain the phenomena of life like good years and bad years, victory and defeat, our own origins, the nature of sunlight an everything else. This is pure speculation (except in the case of Moses and the other prophets who claim to have direct information form the Maker and Controller of the world - not admissible evidence to many). Speculation justified by the fact that it seems to work. Genesis, Plato, Aristotle, Aquinas
You can say what you like to the internet, but if you don't transmit it in Internet Protocol, no one will receive it.
Kreyszig page 49: 'A mapping from a normed space X into a a normed space is called an operator. A mapping from X into R or C is called a functional. Kreyszig
'It is basic that the set of all bounded linear operators from a given normed space X into a given normed space Y can be made into a normed space which is denoted B(X, Y).
COMPLEXIFICATION
[page 2]
We can consider the historical complexification of mathematics as model for the complexification of the Universe.
Operators on finite dimensional normed spaces can be represented by matrices, which are a form of parallel processing, since given two matrices in memory of side n, n2 machines can be assigned to fill in the elements of the product matrix. Otherwise we have nested do loops.
Kreyszig page 50: a vector space is an additive Abelian group.
h bar = RESOLUTION LIMIT of the world.
We make a vector space into a metric space by introducing a norm which measures the length of vectors, the metric induced by the norm. Kreyszig page 59 The metric tells us nothing about their direction, which is the operative parameter in quantum mechanics. Direction is captured by the inner product.
The vast range of possibilities in Hilbert space is not all exploited by nature. In nature, the transformation of states in controlled by an 'equation of motion'.

Quantum mechanical measurement: the measurement basis us decided by the measurer, and the result will be an element of the spectrum of the measurement operator.
[page 3]
In analysis points are defined by sequences which are generally generated by some operator that transforms term(n) of the sequence into term (n+1). This technique is used in the continuum, but discrete results can be determined by finite arithmetic computations: F = ma.
