The Lorentz Transformation

(I don't know if this is enough to 'find' the pdf I'm quoting from or not . . . )

The Lorentz Transformation - UC Santa Barbara

During the fourth week of the course, we spent some time discussing how the
coordinates of two dfferent reference frames were related to each other. Now
that we know about the existence of time dilation and length contraction, we
might suspect that we need to modify the results we found when discussing
Galilean coordinate transformations. Indeed, we will find out that this is the
case, and the resulting coordinate transformations we will derive are often known
as the Lorentz transformations.

To derive the Lorentz Transformations, we will again consider two inertial
observers, moving with respect to each other at a velocity v. This is illustrated
in Figure 1. This time, we will refer to the coordinates of the train-bound
observer with primed quantities. We will assume that the two observers have
synchronized their clocks so that t = t' = 0, and at this point in time, the
two origins coincide.

I'm about a third of the way through 'Relativity' by Albert Einstein, but while I'm understanding what he's saying at a cursory level, at least half sails way over my head. As I told my book club buddy, "I think you and I should read it eight or nine times before we meet for a discussion!"

The fact is, I don't know what a Lorentz Transformation is. Statements such as "This theory was of a purely electro-dynamical nature, and was obtained by the use of particular hypotheses as to the electromagnetic structure of matter" abound and leave me tugging at my hair.

So I'll finish the book and then put it onto my reading list to be read again... and again... and again. Eventually, if I've done the required background work, I'll get it.

For the bookclub, the next book I'll be reading is called 'The Emperor of All Maladies: A Biography of Cancer' by Siddhartha Mukherjee. It won a Pulitzer Prize in 2013 and was the subject of a Ken Burns documentary.
