Well, but no.

The symbols K, k, K' and k' use two variations:
a) small and large letters
b) primed and not primed letters

Now 'small' means 'moving' (of k along the x-axis of K)

But 'primed' means what????

' was used to denote movement in subsequent chapters.

But here k' means the reverted movement of k along the x-axis of K with 
velocity -v.


To me these naming conventions were just terrible.
