I found this formula : $G-G_0=\frac{-nkT}2\delta^2$ on this Site and I'd like to ask what does the $\delta$ stand for?

The next line right beneath the equation you copied says:

...where $\delta=\frac{V-V_0}{V_0}$ is the condensation (e.g. relative volume variation).

Is it too difficult to read one more sentence?

And can you tell me what does it stands for in Czech ? My problem was that when I translate it then it gives no sense for me... – Dávid Kaya Jun 21 '13 at 14:46
Dear user, I don't quite follow whether your question is serious. AFAIK none of the physics terminology or notation is derived from Czech. The Greek letter $\delta$ which is the Greek counterpart of "d" is used for a big fraction of quantities that look like a difference because the word difference starts with a "d" and "differentia" means "difference" in Latin, see - Well, the more accurate story is that delta actually comes from Greek word διαφορά, diaphorá - also "difference". – Luboš Motl Jun 22 '13 at 6:22
I haven't said that it is derived from Czech, I asked because I'm from Czech rep... – Dávid Kaya Jun 22 '13 at 15:37
