    Is there a short form for this equation?

    This is not homework, I believe it is the simplest form, some people might even recognise the equation (it's a famous one), I just wanted it to fit in 1 line on a double column publication

    Is there a short form for this equation?

    D is supposed to be there, I had ignored the square in the first post, in which case D is not neccessary. Now it is. Any ideas how to simplify it now?

    Is there a short form for this equation?

    I have simplified it too much in the minimal working example, the denominators is actually more complicated, let me elaborate: S=A+\frac{L}{D+(B+C)^{2}}+\frac{L}{D+(B-C)^{2}} Any ideas?

    Is there a short form for this equation?

    I am trying to write down a compact form of S = A+L/(B+C)+L/(B-C), does it make sense in general to write down S = A+L/(B\pmC)? Update: I have simplified it too much in the minimal working example, the denominators is actually more complicated, let me elaborate...

    Frame - Frame Grabber and SimplePCI Compatibility for Microscope Imaging

    The truth is I don't know, our system hasn't been used for a while and nobody knows how to work it, the driver is certainly something to try, can you please tell me where should I go to download it? Thanks a lot for helping! Ising

    Frame - Frame Grabber and SimplePCI Compatibility for Microscope Imaging

    Has anyone used the Simple-PCI program to couple with the Meteor-II Digitcal PCI card for imaging from a commercial microscope like the Nikon Eclipse? Our version of the Simple-PCI does not recognise the frame grabber at all. Any help is appreciated. Ising

    Fortran How Can I Define and Use Very Small Numbers in Fortran 90?

    how do I define and use small numbers for computations? on the scale of 10^-30? e.g. Program A implicit none double precision a,b,c,d c = (a*b)/(a+b) d = etc... End program The above has an overflow error when I give a,b the values 3.345 * 10^-27 Can anyone help? Thanks Ising

    Numerical Integration in 3D Space: Fortran 90 Help and Insights | TheIsingGuy

    Thanks. I have figured it out anyways. I already knew about the recipes book and NAG libraries but what I had in about 8 lines of code it took them about 2 pages...

    Numerical Integration in 3D Space: Fortran 90 Help and Insights | TheIsingGuy

    I want to integrate a function in 3D space, and then plot the integrated function, to compare with my analytical solution, I am using Fortran 90, I have no problem integrating, I am just not sure how I can plot the resulting function out. I am currently thinking about piecewise integration...

    Accelerating a space ship to light speeds

    Homework Statement This question basically tries to investigate the feasibility of using a rocket engine to acclerate a spaceship to relativistic speeds, as with any rocket engine fule is ejected at high velocity and spaceship accelerates to conserve momentum. only that in this situation, the...

    Have you encountered this famous matrix before?

    nope, but just wondering what special properties does it have?

    What is the Wedge Product in Theoretical Physics?

    It's a dot product, but for functions rather than for vectors, it might help if you read upon melnikov analysis, a rather useful tool to analyse bifurcation boundaries on the parameter space, it involves the wedge product in its definition.
