indefinite, and vector can have - in general - nonpositive length." Lurco (talk) 08:34, 11 February 2012 (UTC) I changed a = 1, 2, 3, 4 to 0, 1, 2, 3 because...

B) 16:06, 29 January 2012 (UTC) A four-position isn't a four-vector because it doesn't transform like a like vector under a general transformation e.g...

and mechanics. While it is true that a vector is simply an element of a linear space, it is also true that vectors are very useful, and such uses can be...

28 July 2006 (UTC) For the sake of correctness. The * was used in the vector space axioms both as a map * : F x F -> F and as a map * : F x V -> V. I...

a 1st year University level Physics vector (i.e., a Gibbs-Heaviside Vector) is absolutely a quantity. Vectors are neither numbers nor quanities. They...

I am a little surprised that the first example of a vector (in the introduction) is force. I think the idea of velocity as a quantity with magnitude and...
