I've been a professor of mathematics at The University of North Carolina - Asheville since 1997. I've been using Mathematica since I started graduate school in mathematics at Ohio State in 1989. At that time, we used version 1.1 (as I recall) to teach calculus in our Calculus and Mathematica classes. I've used it pretty much continuously in my teaching and research since then.

In addition to my posts on SE, you can find some of my papers, teaching notebooks and other Mathematica based oddities strewn throughout my website.

In recent years, I've also worked as a part-time consultant to Wolfram Research focusing on development of mathematical content for WolframAlpha.

comment Cellular Automata Neighborhood as Node connections
@Schwarz The Mod[Total[Table[value[gen - 1, v], {v, adjacentVertices[u]}]], 2, 1] business sets the new value to either 1 or 2, depending on whether the sum of the adjacent nodes is even or odd.

comment How to solve an operator form of an integral equation by iteration method?
I've rolled back your question to it's original version, as I think your change of dimension is significant enough to warrant a new question. Feel free to open such a new question! Furthermore, no one can really answer this one, as it's closed anyway! (Not that I agree with the closure.)

comment How to solve an operator form of an integral equation by iteration method?
@JavadKazemi I think the same basic idea should work, though it would be nice to have a specific example in mind.

I win - by 10 seconds! :)

comment HoldForm doesn't hold form
@MikeHoneychurch I've updated my answer to address the first example as well.

comment HoldForm doesn't hold form
I agree that you should consider contacting support. I'm not convinced that this is not by design, however. I've always found ThisForm[ThatForm[expr]] to be a bit awkward.

comment HoldForm doesn't hold form
@Jens Does the edit help? I guess that you've got to selectively apply Inactive to Set but not to InputForm. So Inactivate is a bit too coarse.

comment Game of Life in 3D
Since I put some effort into answering your question (and, in fact, read a research paper on the topic) and since the question is just one vote away from being reopened, I've gone ahead and edited the question to make it a bit more specific. Hopefully, it will be reopened. Your original question also mentioned the possibility of playing the game on a network, in the sense of graph theory. If you'd like further discussion on that topic, you might ask another question. Note, however, that's there's nothing a about a graph that is intrinsically 3D, other than it's visualization.

comment Mathematica unable to solve equation numerically while Wolfram|Alpha can
Try Solve[2 x == Sinh[x], x, Reals]. This is a common question - here's a similar example.

comment Strange message appearing when using Wolfram Alpha in Mathematica
I recommend that you restart Mathematica and see if this behavior persists.

@eldo And thank you. It is definitely more life like, now. :)

@Schwarz You should upvote this, if you found it useful. I did.

comment Is this a bug in FunctionDomain (V.10)?
I don't think your Maple comparison is quite fair. You've explicitly asked Maple to solve an inequality, rather than asked for the domain of a function. That doesn't account for more complicated examples, as I've placed in my answer.

Well, I vote to reopen.

comment Rough mesh lines in partially opaque 3D plots
I don't have a windows machine handy to try this at the moment but you might try rasterization. Something like Rasterize[pic,RasterSize->1000,ImageSize->500]. The result is non-rotatable but, in my experience, yields a very nice image which is quite suitable as a standalone image or for export.

@Chenminqi Or, perhaps \[Pi]^2, as it now appears in the code block.
