Thanks CRS, it was novelty to me, you must be into Maths, for certain!

Further research on the subject:

 

http://en.wikipedia.org/wiki/Prime_(symbol)

The name "prime" is something of a misnomer. Through the early part of the 20th century, the notation x′ was read as "x prime" not because it was an x followed by a "prime symbol", but because it was the first in the series that continued with x″ ("x second") and x‴ ("x third"). It was only later, in the 1950s and 1960s, that the term "prime" began to be applied to the apostrophe-like symbol itself. Although it is now more common to pronounce x″ and x‴ as "x double prime" and "x triple prime", these are still sometimes pronounced in the old manner as "x second" and "x third".


In physics, the prime is used to denote variables after an event. For example, vA′ would indicate the velocity of object A after an event. It is also commonly used in relativity: The event at (x, y, z, t) in frame S has coordinates (x′, y′, z′, t′) in frame S′.

 

 

 

There´s this discussion about it, but I think CRS is right, so let´s not complicate it.   Anyway, I brought it up only for information´s sake.
