You won't see much info about me: I am a bit of a paranoid. Or at least that's what people think about me. They don't actually call me that, but I can tell from the way they stare at me.

Oh, by the way: I hate cookies, and I hate websites that won't work because they are invoking third party scripts and cookies without listing which domain should be enabled to allow for posting.

comment Mathematica notebook is corrupt
@YvesKlett , Any idea where to find the Corruption.m package? It appears it has been pulled off of the Web. (I just wanted to have a look at how it worked).

comment Mathematica notebook is corrupt
You probably already did it, but save a copy of the untouched file before trying anything on it. My experience with corrupted mma files is not good, but it should be possible to salvage user content by manually parsing the cell structures. And perhaps some gurus in here can help you recover - for instance - just the code, just the text without all that formatting overhead.

comment Why can't I import a file in the init.m file?
Could it be you have buried your import into a Private context? (EDIT) Mmm, no, you wouldn't have gotten Null...

comment Plotting Integral equation
Can't test the code now, but is it the same if you defined f[k_] = k^2 (d[k])^2 (p[l, k])^2 h[k] /. l -> 1 // FullSimplify, and then NIntegrated f[k]?

comment Plotting an orbit using first principles
Procedural programming is usually not the best way to go in Mathematica. I could show you how to implement the method of solution illustrated in Feynman's Lectures on Physics by using NestList. It uses position and velocities to compute the acceleration and velocities and position at subsequent instants of time. Interested?

comment How do you turn off the Dashed graphics directive?
Looks like a bug, but what happens if you invert Sin and Cos and the corresponding list of directives?

comment I can't Plot the equation -(π/4) + x - 1/2 Sin[2 x] == 0
Plot the function, not the equation! Just remove ==0 from eqn1 or use Plot[x - (Sin[2*x]/2) - (Pi/4), {x, -2, 2}] directly.
