Talk:Flexural strength

message: I'd prefer it if the introductory header denoted sigma as the symbol much earlier - e.g. 
Since I tend to find that I often end up skipping long introductory sentences to get to the equations, and without reading the final words of the introduction, the reader stands no chance of interpreting which part of the equation is the flexural strength. 86.146.54.124 (talk) 15:15, 20 January 2013 (UTC)

message: What is figure 2 supposed to mean? Is it a graph? If so where and what are the axes? On its own it's a meaningless picture and even reading the reference to it in the article doesn't particularly help unless, like most Wikipedia technical articles, you already know what it means.

thread_title:  At yield vs at break 

message: The phrase homogeneous in the chapter Flexural versus tensile strength is, as per my opinion, ambiguous. It is for me less clear to what property homogenous does qualify. From my experience (engineering) I am used to other phrases, like isotropy and anisotropy. For these are already wiki pages as well: [] and []. Please check the material science chapters in these pages. 
These two phrases do emphasize more that the material structure (crystals with metals, polymeric molecules with plastics and fibers with woods) in all directions is identical (isotropic material) or does differ from direction to direction (anisotropic material). In an isotropic material like steel can be expected that the tensile Elasticity-modulus (young's modulus) is equal to the bending Elasticity-modulus or Flexural modulus. The Young's modulus and Flexural Modulus will differ in anisotropic materials. Plastics can be isotropic, but due to production techniques (extrusion) the polymeric molecules are forced in the direction of the extrusion. In practical applications plastics are anisotropic. Natural wood is an anisotropic material because of the direction of its fibers. So for plastics, wood and composites with defined fiber orientations the Flexural or bending Modulus besides the Young's modulus is relevant.  
I've looked around a while on the internet while writing a blog involving this isotropy/anistropy topic as well, so I can tell it is very difficult to find a trustworthy and readable source for the general public about this. Enough research is to be found, but that is often dealing only with a facet of the matter is not readable enough for the general public.  — Preceding unsigned comment added by Teaglass (talk • contribs) 17:48, 21 November 2020 (UTC)

Talk:Floquet theory

message: I'm no expert in the matter, so I'm not editing anything. Having said that, I think that the top lines can be improved; e.g., making it clear in mathematical language that A(t+T)=A(t), and A\in{R^} as well as x\in{R^{{n\times{1}}}}, or whatever applies.

replies: text: The theorem is an existence proof; it places a very strict constraint upon the form of solution. Working from the solution in normal form, there are useful proofs of stability. AFAIK there is no general method of actually finding the solution. (CHF (talk) 18:58, 16 March 2009 (UTC)
replies: text:  While analytic solutions are usually not available, numerically Q and R are found from forward integration, repeated QR decomposition and renormalization of column vectors. It is the same procedure that is used in the determination of Lyapunov exponents and Lyapunov vectors for hyperbolic dynamical systems where A(t) is the Jacobian Matrix at a point r(t) of some trajectory (e.g. a periodic orbit). 141.89.116.54 (talk) 08:20, 30 July 2014 (UTC)

Talk:Flow (mathematics)

message: I elaborated this stub a little bit, adding some examples concerning flows of vector fields. There are also some empty subsections which I will probably work on later if no-one else is willing.
Then there is a question on whether this article should exist as a separate entity. I think it is justified IF there is enough material which is not covered by vector field articles. The point is of course that every flow on a manifold is generated by a vector field, so maybe this article should focus on evolution type PDE's or something.
I have to return to other duties, so there are no suitable references and links yet. Please do not delete on these grounds too soon. Lapasotka (talk) 11:43, 22 March 2011 (UTC)

replies: text: I'm not entirely convinced that having long sections in the article, elaborating these rather basic flows, is a good idea. After all, there are many many flows, and the lead paragraph mentions half of dozen of them, each of which already has it's own separate article.  If these examples are really worthwhile, they, too should get their own article, instead of being jammed in here.  I'm saying this because the article now feels cluttered: it has a whole lot of content, but doesn't say anything particularly deep.  So, for example, I would rather see content that echoes what the springer encyclopedia of math says about flows, and their different types and kinds. linas (talk) 01:53, 29 July 2012 (UTC)

message: There are two types of Fluidyne. The first type has a solid displacer and we have a good image for it. The second type uses a U-tube and a liquid displacer.

Talk:William Bullock (collector)

message: This is a good but rather basic article on an important collector who also wore many other hats: traveler, antiquarian, expert taxidermist, first creator of "habitat groups" in museum display, showman, participant in mining boom in Mexico, c. 1825, travel writer, promoter of panoramas, etc.  I'm a new user of Wikipedia, and thought I'd help out a bit by adding two recent references to the slim list this piece contains, one an article by Michael Costeloe, the other my book, Informal Empire: Mexico and Central America in Victorian Culture, (University of Minnesota Press, 2005), which has two lengthy chapters on Bullock.  Infrog removed the reference to my book without explanation.  This was also the case at a couple of other articles where I thought my book would be of use to others on Wikipedia.
I'm an academic researcher and am interested in contributing, but my first experience here leaves me a bit cold.  Wiki has been widely critized for containing erroneous information.  Here, it's simply out of date and scanty.  Having experts who've published in academic forums might help, but simply removing their contributions without explanation will only put them off.

thread_title: Notes & suggestions

message: William Henry Hall, author of Across Mexico in 1864-5, different guy? —Wiki Wikardo 11:32, 16 October 2009 (UTC)
replies: text: If you're talking about the cricketer and the author of Across Mexico in 1864-5 (and presumably not the subject of this article, the antiquities collector), then I would say that yes, there is a high probability that the cricketer and the author are one and the same person. Their birthyears are the same, the author is also sometimes indexed as "Hall-Bullock" (also Bullock-Hall), and one of the most notable things about his Mexico travelogue is an account of a game of cricket he saw played there. Contemporary reviews of his book that can be found highlight this and indicate that he (the author) was knowledgeable on the game, (without directly referring to any previous career as a first class cricketer, tho). Some contemporary source that mentions both in the one breath would be a clincher, but I'd say it'd be a reasonable assumption to make. But then again, assumptions can go wrong, might possibly be a remarkable coincidence.Were you asking for purposes of disambiguating from this Wm Henry Bullock?--cjllw ʘ TALK 06:17, 20 October 2009 (UTC)

Talk:Hadronization

message: This occurs after high-energy collisions in a particle collider in which free quarks or gluons are created. Due to postulated colour confinement, these cannot exist individually.
If I understand correctly, there is a threshold where a pair of quark-antiquark are so distant from each other that they become "free". Which means being paired again.
So what is this maximal distance between quarks?
Doesn't it yield a fundamental value about the energy density of vacuum, from which the quarks and antiquarks are created during the hadronization?82.236.239.36 (talk) 13:31, 29 September 2010 (UTC)
replies: text: Actually they behave like free quarks when they're close together (see Asymptotic freedom).
