About the physical meaning of second qautization30 Apr 2005 10:13 GMT3
Unfornunately the physical meaning of the second quatization in the
literature stays a little obscured (at least) for me.
As far as I understand (by analogy with quantum mechanics - when one
quantizes the classical variables by replacing them with operators on
Particle Accelerator29 Apr 2005 14:40 GMT1
Back around about the same time of the demise of the Texas Super Collider
(TSC) a decade ago I ran across an article which pointed out that an even
more powerfull particle collider could be built using a laser with the
apparatus the size of a football field. Not only would it be ...
Elementary Particles25 Apr 2005 12:54 GMT2
Some time ago, when I was about 20, I suggested that elementary particles
are actually photons that get stuck by their own gravity.
If the energy of an element of a electromagnetic wave is E^2/c where E is
the local electric field then the equivalent elemental mass is given by the ...
Settling a bet: is the smallest action h-bar or h-bar/2 ?22 Apr 2005 12:32 GMT89
My cousin and I are fighting (well, discussing intensely)
over an issue which is not often discussed. We now
have a bet ongoing; who wins is allowed a trip
to the Einstein tower in Berlin paid by the other.
h bar and Lorentz transformation18 Apr 2005 20:16 GMT52
The constancy of the speed of light is usually mentioned as one of the
corner stones of special relativity.
How about the constancy of h bar, it is like c, a universal constant
too but it is never mentioned as a corner stone of quantum mechanics!!!

Evidence of the Existence of the Aether
"Great spirits have always encountered violent oppositions from mediocre
minds." - A. Einstein
    It is the currently accepted "truth" that there is no experimental
What it takes to be a revolutionary thinker07 Apr 2005 17:37 GMT216
I had a high school student come into my office on campus one day. He
had been encouraged by his mother to come visit the physics department
to discuss his ideas because she thought he was brilliant. The
department chair, in his infinite wisdom, sent the young man to me.
Sub-atomic particle structures04 Apr 2005 14:42 GMT13
To study sub-atomic particles, physicists have to use devices like
SuperColliders and other particle accelerators. What if there's another way
other than dumping in loads of kinetic energy?
Most things, at least on a macroscopic scale, that have a mostly consistant
Just do it!04 Apr 2005 05:42 GMT19
One of the big failures of modern science is
failing to confront the existing and coming Energy crisis.
for instance:
the failure to produce cheap fusion
Do photons have temperature?02 Apr 2005 10:04 GMT11
They have mass they have energy, momentum... but do they have classical
thermodynamic properties?(For example, temperature, entropy,
enthalpy,etc)
If true, doesn't that mean a electromagnetic field has a temperature??
