AU PAIR AGENCY IN AUSTRALIA

 

If you are looking for personal service from a highly experienced au pair agent for Australia,

I strongly recommend contacting Jillian at Select Au Pairs and Nannies.

http://www.selectaupairs.com.au/

Jillian started her agency in 1996, the first au pair agency established in Sydney.

She places au pairs and nannies throughout Australia.

 

Matching families with au pairs requires skill, as different personalities suit different families.

When starting her agency, Jillian had extensive experience in the recruitment industry.

Since then she has introduced au pairs to thousands of families and has become very good at finding good matches.

Finding the right au pair for a family is important, but providing support is also important

as things don’t always run smoothly – au pairs can get homesick, children can resent an au pair.

This is where Jillian’s extensive experience and personal touch are a great help.

Her charges are lower than most, and she does not charge a fee until a placement is made. 

 

I should declare my bias and relevant experience – Jillian recently agreed to marry me. The au pair industry was

unknown to me until I met her,  but I have plenty of experience of waiting patiently while she responds to

calls from mothers, fathers and au pairs, at times of the day when someone in a normal job would be unavailable.

 

Aside from Jillian, another enthusiasm of mine is thinking about the fundamentals of physics.

Despite being a total amateur, I managed to get a paper published. I plan to update and revise that paper, as

I’ve developed the concepts more fully, revising some elements. My description of my original

approach was:

 

THE PATTERN OF REALITY

The basic elements of the universe comprise the bosons and the three families of fermions of
the standard model together with, possibly, gravitons, Higgs bosons, dark matter particles and
bosons responsible for "dark energy". Ideally, these different elements should arise as a
consequence of the geometry of the universe. If this is the case, there might be a correspondence
between the phenomenology of the fundamental particles and a phenomenology of possible
orientations of sub-elements of the universe's geometry.

"The Pattern of Reality" is an attempt to identify the geometry of the universe by finding a
mathematical structure with a pattern which corresponds to the pattern observed for the
fundamental particles of the standard model. The mathematical structure found is an
assembly of special unitary and pseudounitary subalgebras of the Clifford algebra isomorphic
to complex 4x4 matrices.

This pattern is found to correspond to the pattern of particles of the standard model.
There are further subelements that could be associated with dark matter.
The pattern is generated by postulating a 31-dimensional (2^5-1) manifold which undergoes
spontaneous symmetry breakage resulting in 15 "real" dimensions of which four dimensions are
reduced to ultra-compact (point) scale, reducing its effective dimensionality to eleven.

A paper describing the pattern has been published by the journal
"Advances in Applied Clifford Algebras" volume 18,(1)
Given the role of special unitary and pseudounitary subalgebras in physics, and the relationship
between Clifford algebras and space-time, this pattern, found at the intersection of matrix representations
of components of a Clifford algebra with matrix represenations of special unitary and pseudounitary
symmetries, and having the look and feel of the standard model, looks like it ought to be significant.

An apparent weakness is the sector identified with neutrinos. For neutrinos, three equivalent elements
are identified with neutrinos in a way that matches that in which three equivalent elements
are matched with down quarks. This might imply that color forces should exist betweeen different
flavors of neutrino which is not the case. An explanation might be that forces between neutrinos
are mediated by bosons confined to the same trajectory as the neutrinos, so that the only effect
is a self-interaction, observed as oscillation between flavors.

A possible weakness is the inherent fudge factor available as a result of the scope to associate
any elements not fitting the standard model with dark matter. This would turn into a strength if
dark matter and dark energy is found to match the pattern. It may be hard to investigate the existence
of nullitons if their only interaction with normal matter is through gravitation and they do not undergo
weak interaction with normal matter.

When forces for normal matter are fully understood, it may be possible to predict the behaviour of
forces for dark matter. Essentially the difference lies in the application of spontaneous symmetry
breakage to color forces instead of to electroweak forces. The effect of breaking symmetry for
color forces appears to create a long range force mediated by a boson labeled the faxon
which would be the color force equivalent of the photon. If faxons can interact, their force law
could be inverse linear. It would seem possible for the strength of this interaction to allow
interactions between faxons to have the effects on the evolution of the universe that are attributed
to dark energy. It would be helpful if dark matter particles' contributions to vacuum energy exactly
cancelled out those of normal matter.

(I cannot remember where the name 'faxon' came from - I used 'fusons' because fusing varks could correspond to
gluing quarks, and 'texons' because of the idea of a super-strong texture force & as everything is bigger in Texas)

If the pattern is significant, it prompts the question - what are the scales? One estimate could be made by
assuming that the Planck scale is the ultracompact scale, and the size of the universe is the
extensive scale, and taking compact scale to be the geometric average of the ultracompact
and extensive scales. Taking the size of the universe to be the comoving radius:
=46.5 billion light years = 4.4.10^(26) metres
and the size of the ultracompact space-like dimensions to be the Planck length
= 1.6.10^(-35) metres
The geometric average is:
8.4,10^(-5) metres or 0.084mm

However, this approach implies continuous variation of the scales with time which, if the properties
of matter are a function of the geometry, implies variation of fundamental constants as the universe expands,
which has not been observed. An alternative hypothesis would be that the scale changes occurred during the inflationary
period of the expansion of the universe. At the start of inflation all dimensions would be of compact scale,
and no distinction would exist between dimensions later to be associated with real matrices and those to be associated
with imaginary matrices. The driving mechanism for inflation would be the symmetry breakage creating the distinction
dimensions later to be associated with real matrices and those to be associated with imaginary matrices.
At the end of inflation extensive and ultracompact scales would be set, and no further changes would occur.
For this approach, the size of compact scale would be the Planck length. At the end of inflation, extensive scale
would be set at the size of the universe at that point, of the order of 0.1 metres, implying that ultracompact (scalar)
scale would be of the order of 10^(-69) metres. I conceptualise this process as an elastic expansion to a breaking point.

In terms of platonic ideals, for this approach, the ideal for the universe would be a manifold defined by subalgebras
of sl(4,C) having special unitary and pseudounitary symmetry, whose symmetrical form is metastable, so that its
symmetry would break resulting in inflation. The duration of inflation could be inherent in the mathematics of
the manifold, or it could be a free parameter allowing the possibility of a "tunable" universe. So, the properties
of our universe could be totally determined by its geometry, or could be a function of a single parameter - the ratio
of extensive scale at the end of inflation to the initial scale at the start of inflation.

If the process of creation of a surplus of matter over antimatter is similar (or inverted) for dark matter
as for normal matter, the mass of the nulliton could be estimated using the assumption that the
number of particles in existence is proportional to the number of subalgebras available,
so that the ratio of nullitons to hadrons would be 9:6. Since the ratio of mass of dark matter
to normal matter is approximately 22:4, this suggests a nulliton mass of 3.7 times that of the
hydrogen atom, 6.2.10^-27 kg or 3.44GeV/c2

The concept of a universe as an object with an aspect ratio of 10^68 or more seems improbable.
The many worlds interpretation of quantum mechanics, suggesting infinite branching of an infinite array of
of universes also seems improbable, especially as there is no continuity between adjacent universes
(one may feature a living cat where the adjacent universe has a dead cat). These issues arise
as a consequence of adopting a world view influenced by the concepts of general relativity, for which the naive
model is a deformed elastic surface. An alternative naive model would be to consider the observed universe
to be a propagating wavefront, as this would feature a small amplitude for an extensive object.
For this model, manyworlds interpretations can be made. If our universe is wavefront of coherent events
at loci in a wavefront having 4 extensive dimensions embedded in a macroverse having 31 extensive dimensions,
many other similar wavefronts can exist within the macroverse. For this model, bandwidth becomes an
applicable concept, linked to quantum uncertainty.

When considering EPR experiments, such as measuring spin for widely separated particle pairs,
consideration needs to be given to how and when it is established that the widely separated observers
occupy the same universe. No hidden variable is needed to instantly communicate spin state status
between the widely separated entangled particle pairs if all possible spin states occur and are observed
by observers in different universes. Effectively, an observation by a distant observer of a distant event
would not collapse the wave function for the event for the local observer until communication between
the observers establishes that they are part of the same universe.

On the basis that, to be taken seriously, a theory has to have a whimsical name, and since the
pattern includes dark matter particles labelled "hard varks", I'm suggesting that the theory of everything
based on this pattern should be called the "Aardvarks TOE".
