Hello, I want to solve the 1-D stationary Boltzmann transport equation where the collision integral consists of electron-electron interactions. The boundary conditions are...

Dear Physics Gurus and others I have a question about statement that I read on a website about a year ago. The statement was about that when symmetry is broken, that which...

Have you ever seen a scientific related image and thought "wow, that's just beautiful!"? I came across a couple of university internal "art of science" competitions where...

http://groups.google.com/group/sci.physics.research/browse_thread/thread/b49bf2890b24e27f# Like many physicists, I am not too worried about black holes at LHC. But what if...

Recently I happened to read two papers that pretend that the quadratic divergence of the Higgs mass is not a problem. The first is "From Quantum Hydrodynamics to Quantum...

What's the difference b/t a "density profile" or "temperature profile" etc and just a basic density graph, temperature graph, etc? (Cosmological simulations). Is a profile...

I'm a retired Ph.D. physics with a publication record of around 18 papers in nuclear and particle physics from work I participated in a few labs (CERN, Fermi, UCLA, IUCF,...

What is the best argument as to why a gluon could not be considered as a composite of two quarks of differing (anti-) colors?

What's the difference b/t a "density profile" or "temperature profile" etc and just a basic density graph, temperature graph, etc? (Cosmological simulations). Is a profile...

Good Morning, I was wondering if one would dispose several levers in parallel (having the same length), having them communicate the force between the successive levers by...

I have noticed that recent issues of the journal Chaos, Solitons and Fractals have the same author for more than 10% of the published papers, and that author also happens to...

Like many physicists, I am not too worried about black holes at LHC. But what if we did have a small black hole somewhere on earth. What would happen? Most non-physicists...

A few simple questions: 1) Whats the exact value of Hydrogen line? 2) And under what condition(s) is this value holds true? Regards, Jay Bala.

This isn't exactly a research-level question, but it seems too technical for sci.math or sci.physics. I'm trying to learn differential geometry from a book by John Baez and...

If dark matter can't even escape the surface of the earth then why don't scientists include dark matter into their models and calculations of the mass of planets and...

Hi, I am reading in the introduction of hep-th/0208013: "the low entropy starting point is the ultimate reason that the universe has an arrow of time, without which the...

Hello, I'm trying to understand the difference between Adiabatic Quantum Computation and "traditional" Quantum Computation. I'm not a physicist, my background is in computer...

Hello, When each component of the stress-Energy tensor is divided by a mass density, the result is a tensor object in which each component has the same units as velocity...

Hi Galieo's Dialogues on two world systems has just been translated and published in Turkish. I know this group has an international audience, can you tell me if and when...

In Kerr spacetime there exists CTC's (t,r, theta constant and phi varying from 0 to 2pi) located in the negative space time (r 0). It is tempting to compute the holonomy of...
