Definition talk:Vector Quantity

There doesn't seem to be much consistency in vector notation on PW, $\bf x$ or $\vec x$. Is $\bf \vec x$ too heavy handed? Is it too minor a thing to care about? --GFauxPas 13:05, 15 November 2011 (CST)
 * Some contributors prefer one notation, some another. Some of them get cross if you change their favourite notation on the page they wrote for another notation. The answer is to recommend a house style, admit in the definition page that there are alternative notations, then when the offending editor has got bored and gone change them to the notation that is preferred by me defined as house style.
 * In short: in this case it doesn't really matter although, either $\mathbf x$ or $\vec x$ is usual, would prefer it didn't deviate from either one of those. Have we got any instances of $\vec {\mathbf x}$ or $\mathbf {\vec x}$? Oh, and it ought to be \mathbf not \bf, there's a technical reason why but I can't remember what that reason is. --prime mover 14:59, 15 November 2011 (CST)
 * No I haven't seen $\mathbf {\vec x}$, I just was suggesting it as a best of (worst of?) both worlds option. --GFauxPas 15:02, 15 November 2011 (CST)

Disambiguation
As suggested by Alecscooper on GFP's talk page, there should be a disambiguation here. Due to the large amount of discussion, I haven't proceeded immediately. Rather, find below a list of different pages called Vector I propose:


 * Definition:Vector: disambiguation
 * Definition:Vector (Physics) or Definition:Vector (Applied Mathematics), or both: What was described as 'directed line segment'
 * Definition:Vector (Vector Spaces): an element of a vector space
 * Definition:Vector (Euclidean Space): what we all know as a vector (i.e., something that a matrix acts on); or redirect to
 * Definition:Vector (Linear Algebra): alternative for 'Euclidean Space'

That's all I could think of. Be sure to use About. --Lord_Farin 11:10, 27 January 2012 (EST)
