    Solving Bibtex Referencing Problem for Multiple Papers in Same Year

    I am having a problem with bibtex when I have a second paper by the same author (or at least the same lead author) in a single year. For example if I have two papers, with the following authors: Paper 1 - Author 1, Author 2, Author 3, Author 4 (2008) Paper 2 - Author 1, Author 5, Author...

    LaTeX Problem with LaTeX hyperref package

    Ok I managed to solve the problem. For anyone else that might be interested: I was including the package with: \usepackage{hyperref} However if I include it with: \usepackage[dvipdfm]{hyperref} Then it works when I use dvipdfm to convert to pdf.

    LaTeX Problem with LaTeX hyperref package

    I am having some trouble with the hyperref package in terms of it not actually providing links to my internal references. If I use the pdflatex command to compile my document to a pdf, the links work fine. However if I use the latex command to compile to a dvi and then dvi2pdf (or whatever...

    Deriving the continuity equation from the Dirac equation (Relativistic Quantum)

    Ok so it turned out I had multiplied the wrong function on the left. It worked out quite simply when I fixed that. The lecture notes had erroneously shown both functions multiplied on the right. Thanks, tiny-tim.

    Deriving the continuity equation from the Dirac equation (Relativistic Quantum)

    I tried that and got something else that didn't work. However I will try again because I was surprised that it didn't work so I may have made a mistake or missed something obvious...

    Deriving the continuity equation from the Dirac equation (Relativistic Quantum)

    So I am trying to derive the continuity equation: \frac{\partial}{\partial x^{\mu}}J^{\mu} = 0 From the Dirac equation: i\gamma^{\mu} \frac{\partial}{\partial x^{\mu}}\Psi - \mu\Psi = 0 And its Hermitian adjoint: i\frac{\partial}{\partial x^{\mu}}\overline{\Psi}\gamma^{\mu} -...

    Aperture Stops, Entrance Pupils & Exit Pupils

    I'm doing an assignment involving an optics question. There is a lens (diameter 4cm, focal length 5cm) an apeture (diameter 5cm, position 2cm in front of lens) and an object (1.5cm high, 8cm in front of lens). Now I have determined that the lens is the aperture stop. Now, because the lens...

    Velocity of mechanical waves

    Ok, so the velocity of mechanical waves through a medium is equal to the square root of some elastic property divided by some inertial property... I did a quick search on google and a couple of textbooks and cannot find any actual explanation as to why this is. It is intuitive, yes, but...

    Deriving Distance Modulus: m - M = 5log(d/10)

    Ahh yeah I worked it out now... m1 - m2 = 2.5log(F1/F2) Just needed to be reminded that absolute magnitude is what the apparent magnitude would be at a distance of 10 parsecs...

    Deriving Distance Modulus: m - M = 5log(d/10)

    Distance modulus derivation (I hope this is the correct subforum) I was wondering if anyone can help me, I am hoping to show a derivation of the distance modulus m - M = 5log(d/10) It looks very similar to the m = m(sun) - 2.5log((L/L(sun)).(r(sun)/r)^2) so I'm assuming that they...

    What is the resistance of R1 ?

    For a class I'm doing I have an assignment where we have to do a report on a Space Science Instrument. I am doing Cloud Profiling Radar. Part of the report has to involve some calculations which basically just apply out knowledge of physics to the properties of the instrument. The...

    Whether this statement is true or false

    (x^n - 1) = (x^(n/2) -1) (x^(n/2) - 1) = (x^(n/4) - 1)(x^(n/4) + 1)(x^(n/2) + 1) and so on, where the power of x is n/(2^k). Consider the case where n is odd, dividing n by 2^k will never equal 1.
