3 Principles of Success (Harford)

  1. Seek out and try new things.

  2. When trying something new, do it on a scale where failure is survivable.

  3. Seek out feedback (to determine your level of success) and learn from your mistakes as you go along.

@Öskå I don't know how to make Mathematica code nice-looking readable on this site, hence posting pictures and using external site. If you can say how to make it nicer and more readable, I will do my best.

@kguler could Defer or HoldForm work with the denominator of the solution "$1+\frac{k_{ro}\mu_{ro}}{\mu_ok_{rw}}$"? Vries solved the derivation to zero puzzle. Now I am trying to force Mathematica to have a certain denominator, could your tip work for that?

I like the fact that you are never giving up +1, real hxcker attitude! Sometimes it is muddy but always fighting to the goal. Thank you.

Update did the code in two different methods, MapThread just not working yet here, why?

Can you elaborate this with another function such as the ready CoordinateTransform where you don't specify the & explicitly? How to use MapThread with it? I am trying to do it with it now to replace the self-done function here. I must say that I am so confused to Mathematica, why on earth they cannot get the shxt out and design the syntax clean (sorry just frustrated in trying to understand a simple thing like tuple manipulation).

@Verbeia I wish I knew even myself: manipulating tuples requires to be just some super guru in Mathematica, syntax so hard in comparison to Python, cannot understand how to get inside that -- trying to do the same example Spherical-Cartesian now with the ready CoordinateTrasform and MapThread (not working), why? i.stack.imgur.com/M8dCh.png

Actually, you are right in this +1 -- took me a long time and Freenode gurus to hit me a little! Transpose is the equivalent to Python's Zip -- dxmn I got a new question here. The real challenge is how to operate the tuples in Mathematica by the Spherical-Cartesian function. Somehow with ## and &...ideas?

It is so much easier to write things in Pastie, I wrote a bit larger example that I want.
