Just trying to get my head around the very basics of the Higgs discovery. Could someone describe the relationship between the Higgs Field and the Higgs boson. A confusing point for a layman like myself is that if the particle decays so rapidly, how is it that there is an omnipresent Higgs...

Hello everyone, I have a question that I have spent many nights pondering and hours on my whiteboard considering. I apologize in advance if this question seems a bit elementary, but to me it is something that I believe is all important before I can understand all of calculus. How is...

Hi, I can't go out and measure this system up atm. But I have 36m^3/s flow rate at 400kpa. How would I go about predicting the flow rate at 500, 600, 700 and 800 kpa through the same pipe? I think it's a linear relationship but want to be sure. Thanks.

Hello, I am a general physicist, pursuing it for fun. I work in solar, and the other day while driving up to Sacramento I had a interesting train of thought. From the data we have collected, one interpretation could be that on average, the universe is expanding in every direction at an...

As I understand it, the absorption coefficient of a surface of material is the same as its emissivity (due to Kirchoff's law of thermal radiation), and that the net of this and the tranmissibility is emissivity + reflectivity + transmissibility = 1 Is this a general statement about...

If the product of pressure and volume over temperature is equal to some constant for a particular ideal gas. Let's say the volume is just a vessel and the pressure in the vessel is increased. So effectively the volume remains the same. Any increase in pressure must be canceled by an increase...

P = \left( \begin{array}{c} E/c \\ \bar{p} \end{array}\right) and U = \left( \begin{array}{c} \gamma c \\ \gamma \bar{v} \end{array}\right) right? But I frequently see in textbooks that P = m_0 U . Surely, m_0 U = \left( \begin{array}{c} \gamma m_0 c \\ \gamma m_0...

I'm looking into the stability of a system of ODEs, for which we've mannaged to extract a Jacobian matrix. Two of our eigenvalues are within our nummerical error tolerance, but they are close to zero. One of them is positive, which poses a problem for our stability analysis. We do know that...

I want to know why the moment could be represented as the product of the bending stiffness and the curvature. I do not quite understand the function of the curvature in the formula. http://en.wikipedia.org/wiki/Curvature

i have been given to understand that the standard model is not a "particle" theory (even though the only things listed there are particles), but rather a "field" theory. i also (somewhat) understand that particles are not actually "things", but rather manifestations of the underlying field...

Are there any special relationships between the column vectors of a matrix and the corresponding column vectors of its inverse?

F=GM1M2/r^2 The force of gravity without mass is 0. Wouldn't this imply that gravitons and higgs bosons come in pairs? Is there any evidence of gravitons and higgs bosons existing only in pairs?

The drag force can be affected by the velocity of the object relative to the fluid. Does that mean the wind affects the drag force, since it changes the velocity of air particles?

Hi all, I am in introductory physics and we are doing a self-designed lab. For my lab, I wanted to study the relationship between the wavelength of light and voltage. To do this, measured how much voltage drop there was in a single celled solar panel when I put colored filters over a light that...

So I feel like a complete moron for asking this. I have never been very strong in geometry so I wondered if a few math folks could help me out. I am just looking for the angle relationships of gamma, alpha, and beta. This is just a small piece of a much larger analysis that I am doing. I...

Is there a way to take a known path, all the existing forces/fields along it, and solve for a driving force function that results in an object moving along that path? but solving it without knowing the speed along that path, only the path itself, and maybe the total time taken from A to B along...

Sorry, If I couldn't reach out for the actual meaning of my question. Its my bad english. Q : What's the exact relationship between charge and the mass? I found that charge never exists without mass. It should have any amount of tiny mass associated with it to exist. So, why is it so? If there...

I understand everything up until: √MgL/m = L/t Why is that equal to L/t? I also don't understand this either: This is the problem itself however I don't feel it's that important since I am trying to figure out how they are arriving at their conclusions. An astronaut on a small...

Is it true that if an n by n matrix A has n-linearly independent eigenvectors, then it must also be invertible because these n-eigenvectors span n-space. But does this reasoning work the other way around: that is if A is invertible, does that imply n-linearly independent eigenvectors can be...

Hello, Does the column space of a matrix A always equal the column space of the rref(A)? i.e. are the solution sets to Ax=b, or even Ax=0 the same for A and rref(A)? When doing some examples of matrices that had some linearly independent columns it seemed the Span was preserved by row...
