I work for Wolfram and oversee Wolfram Community. I am a physicist, Mathematica enthusiast and faculty member at Wolfram Science (NKS) Summer School. I am an author at the Wolfram Demonstration Project and sometimes write for Wolfram Blog. I enjoy creating applications and art with Mathematica, some can be found on my website. I also collecting Mathematica graphics at a Pinterest board and organized a video group Mathematica Render on Vimeo.

comment FindFit with parameters which are simultaneously in initial conditions
@Krzysiek In such case I would try using ParametricNDSolve - look through the examples HERE to grasp the scope.

comment Find patterns in a list
@b.gatessucks very nice +1 but i'd put a___ and b___ - BlankNullSequence - to include boundary cases for more general situations.

comment Speed up ContourPlot3D
@Stephen I know that ;) I was trying to share a general useful trick. And as you can see even Kuba adopted it for his code - in addition to his idea. Because it often makes things better.

comment Speed up ContourPlot3D
@Stephen i've seen it - it is a nice idea working in this case. but that's not the point of my post. in some situation you will not be able to replace ContourPlot3D with Plot3D.

comment System of differential equations - solving for a constant
And please correct all system symbols like E and N in text and in code. If symbol turns black color from blue and is not defined it means it is a system symbol. Do not use them for variables.

comment Any way I can solve this integral?
@seismatica I wanted to remind people it exists ;-) - rarely used. Smoothness is an illusion - there is sampling anyway: Plot[NIntegrate[1/(Sin[s/2]^b + 1), {s, 0, Pi}], {b, 0, 3}, Mesh -> True, MeshStyle -> Red] It is faster - because you control sampling.

@belisarius this time you really cracked me up... and i thought it's the children for whom the trees are taller.

Well "it is not V9" says it all ;-) You can actually get same thing now on Raspberry Pi.

Welcome to Mathematica.SE! I suggest the following: 1) As you receive help, try to give it too, by answering questions in your area of expertise. 2) Read the FAQs! 3) When you see good Q&A, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. ALSO, remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign
