per unit length
The "per unit length" term is used for quantities that depend on length in the limit as length goes to zero. That is, in general impedance is not a property of the whole system (cable), but of each tiny section. Reflections occur at impedance discontinuities. The impedance of a (limit as the length goes to zero) section of cable is the square root of the ratio of the inductance per unit length and capacitance per unit length. As both can vary along the cable, it isn't inductance/length but d(inductance)/d(length). Gah4 (talk) 17:45, 10 August 2015 (UTC)

Langevin equation
Hi Rdengler, you reverted the edit in the article about the Langevin equation. In the book that I referenced the Langevin equation is employed for each particle in a N-particle system and still called Langevin equation. So there is no need to revert the edit. PS: Please provide a reference for the correlation function so that readers may check it directly. This was the reason I cited the book. --Biggerj1 (talk) 16:11, 7 April 2016 (UTC)

Langevin equation
Hi Rdengler, You insist that the coordinate is 3-D and reverted my edit. In theory you are right, but it wasn't explained anywhere in the text. So please consider modifying the text AS WELL AS the formula, or revert my edit. Thanks

>> Added Aug 30. Dear Rdengler, Please motivate your reversion of the page without referring to my mental skills or the age of the article. Otherwise I will have to call for arbitration. As I already indicated you, the indices i and j are not defined anywhere above or right after the formula we are talking about, so they don't have any meaning. I don't mind your version, but you have to specify that the indices correspond to the components of the vector. In the present form the page is mathematically incorrect.
