CERN's LHC is scheduled to start operation in 2007.
Our Final Century, a 2003 book by Sir Martin Rees
(http://www.ast.cam.ac.uk/IoA/staff/mjr/), a scientist with impeccable
credentials, describes the following extreme risks:

I wish to notify the readers of my solution to a problem that has
regularly been discussed in this newsgroup.

This Week's Finds in Mathematical Physics - Week 221

Anybody knows how to prove, or at least knows the reference that shows,
that the special pseudo orthogonal group has exactly two connected
components?
By special pseudo orthogonal i mean, the group of all linear

As has been discussed at length recently here, Lorentz ether theory is
almost universally regarded as equivalent to special relativity. In
mathematical form, namely in the form of the lorentz transform, this is
a necessary truth, since the interpretation of an equation is really

Most textbook treatments of gauge transformations do it in
position space. So far, I haven't found any that discuss
in detail what they look like in momentum space, and what
issues arise in the QFT Fock space.

I'm trying to find graphs or measurement data of the Molar extiction
coefficient of IR-dyes, such as:
Gallium(III) 2,3-naphthalocyanine chloride
Vanadyl 2,3-naphthalocyanine

I am well aware that a number of physical models contain or predict
singularities. My question is: Is there any experimental evidence that
any singularity actually exists or are they all artifacts of the
models?

I would like to point out,once again,that the definition of proper
time in General Relativity needs to be modified/corrected. Even
though the present definition  dTau = ds/c for timelike geodesics
(Tau = proper time, ds = infinitesimal interval), gives correct

I've been trying to 'get' spinors, and I would appreciate a little help
with a question on chirality.
In two dimensions the two component spinor is mapped onto the vector
space via the Pauli matrices sigma_1 and sigma_2. Eg x = psi^{dagger}

I would like to prove here that Maxwell's electrodynamics
is not Poincare (= relativistically) invariant. In particular,
I would like to show that inertial transformations in this theory
do not form the Poincare group. I just need to provide one

Dear Sir,
Now I am studying about NiP2 crystal structure especially electron
density distribution. One thing I would like to know is that I couldn't

Some time ago I got worked into the idea ([1],[2]) that all physical
instances of probabilities are just squared moduli of quantum
amplitudes, which the observer is often unable or unwilling to track.
This was the result of some deconstructive  argument on the distinction

What is known of the quantum function of mirrors?
I mean, forget 'beams' and 'rays' of light and geometric angles etc., what
are the photonic considerations?
Any insights welcome, (pun intended -- though I am serious, well, mostly).
