I do agree with you Tom.

I can add that to complete the Standard Model, we need to confirm the
exiscence of these scalar fields and find out how many types there are. This
is a matter of discovering new elementary particles, often called Higgs
particles, that can be recognized as the quanta of these fields.

We have every reason to expect that this task will be accomplished before
2020, when the accelerator called the large Hadron Collider at CERN, the
European laboratory for particle physics ner Geneva will have been operating
for more than a decade.

The very least thing that will be discovered is a single electrically
neutral scalar particle, It would be a disaster if this were all that were
found by 2020, though, because tht would leave us without a clue to the
solution of a formidable puzzle called the hierarchy problem.

The heaviest known particle of the Standard Model is the topo quark, with a
mass equivalent to an energy of 175 giga electron volts. One GeV is a little
more than the energy contained in a proton mass.

The not yed discovered Higgs particles are expected to have similar masses,
from 100 to several hundred GeV. But there is evidence of a much larger
scale of masses that will appear in equations of the not yet formulated
unified theory.

The gluon, W, Z and photon fields of the Standard Model have interactions of
rather different strengths with the other fields of this model; that is why
the forces produced by exchange of gluons are about 100 times as strong as
the others underd ordinary conditions.


Gravitation is vastly weaker: the gravitational force between the electron
and proton in the hydrogen atom is about 10^-39 the strenght of the electric
force.

Theorists have proposed several interesting ideas for a natural solution to
the hierarchy problem, incorporating a new symmetry principle known as
supersymmetry or new strong forces and so on.

So, you're right and I do agree with you, QM is too difficult to understand
than special relativity. Of course General Relativity is difficult to
understand too about his difficult maths.

Thank you a lot Bob
