[Moderator's note: I have set followups to the poster. -P.H.] Hi there, From a personal passion for science and technology I have created a self organizing website where you can post your most interesting science video's and books. The adres is [link]. As the site is relatively new I would like to request your feedback to... more »

Virtual Photons and the Infinite Range of Electromagnetic Interaction
|
| |
Virtual Photons are responsible for electromagnetic interactions which extend for an infinitely large distance.When these virtual photons are shot out of charged particles the process conforms to the principle of momentum conservation but energy conervation is violated. They move with "borrowed energy" which is accommodated with the help of the... more »

Why does the renormalization group work?
|
| |
Why does the renormalization group work so well? In fact, why does it even work at all? Before you think this is a dumb question on my part, please consider this for a moment. The renormalization group involves "decimating", i.e. integrating away the ultraviolet degrees of freedom. The basic idea of the renormalization group is that as long... more »

QM Tunneling & CoE

...ar represent the left side of the tunneling barrier, the < char is ...This is a poor choice of newsgroup for this question. I will repost it in sci.physics.foundations separately, as they do not permit cross- posting. I am also posting to sci.physics.research, as there are some brains operating there. Both newsgroups are moderated, so your... more »

spacetime curvature and Unruh's effect
|
| |
Hi to you all! below, ~ stands for "proportional to" , and R stands for Riemann's spacetime curvature tensor. Here is my question: 1) According to Unruh, a rocket with proper acceleration A feels a thermal bath with temperature T ~ A 2 ) the thermal bath has energy density D ~ T^4 (Stefan law).... more »

Though Experiment - Density and Bouyancy
 
|
| |
I have attempted a simple thought experiment with buoyancy and density changes and have attempted to model the situation mathematically. The main objective have been to investigate the relationship between applied work and energy potentially harvested from the system by changing the density of an object with with one mechanism and... more »

Charged or Neutral Strong Nuclear Force Exchanges?
|
| |
I note that, at [link] the strong nuclear force (now re-christened nuclear force or residual strong force) is currently illustrated as a neutral pi meson exchange (itself further complicated by representation of such a neutral meson exchange as a residual consequence of the standard model)... more »

M-theory on the sphere S2??
|
| |
Hello, can anyone point to preprints on compactification of M-theory down to 9 dimensions, via the sphere S2? I am curious about: - how should this compactification be different of a compactification first in S1/Z2 and then in S1? - is it the same that heterotic compactification in a circle S1? - would a Kaluza Klein SU(2) group appear in this compactification of... more »
