Galilean transform equations In An introduction to the mechanics of Galileo and Newtonwe saw that converting between two inertial frames was easy.

## Lorentz Transformation Equations

The important point is that although these events appear to occur in lorentz transformation equation different order in a different frame, neither of them could be the cause of the other, so cause and effect are not switched around. From the second of these principles, with a simple thought experiment, we can derive the Lorentz transformations from first principles.

These are the equations which allow us to translate from one frame of reference to another so that all the laws of Physics are invariant. Let's say we have a system like the one on the right.

A stationary observer in the S frame observes an event in the S prime frame. You can kind of see the positive ct axis is in the lorentz transformation equation quadrant here because I'm traveling with the velocity of negative v, but these angles are going to be the same.

This is going to be alpha and that is going to be, let me write this, is going to be alpha and this is going to be, and this right over here is going to be lorentz transformation equation.

Now what I want to do in this video is use this symmetry, use these two ideas to give us a derivation of the Lorentz Transformation or the Lorentz Transformations. And the way we might start, and this is actually a reasonable way that the Lorentz Transformations lorentz transformation equation stumbled upon, is to say, all right, we could start with lorentz transformation equation Galilean Transformation, where we could say, all right, the Galilean Transformation would be x prime is equal to, is going to be equal to x minus v times t.

Now we already know that if you just use the Galilean Transformation, then the speed of light would not be absolute, it would not be the same in every frame of reference.

And so we had to let go of the constraints that time and space are absolute, and so there's going to be some type of scaling factor involved. And so lorentz transformation equation can call that scaling factor, gamma.

So, we could say all right, let's just postulate that x prime, if we assume the speed of light is absolute, is going to be some scaling factor, gamma times x minus vt. Well, you could make the same argument the other way around. If you view it from her frame of reference, and you're trying to translate it to my coordinates, you could say, lorentz transformation equation, x, instead of just using the Galilean Transformation that x is going to be equal to, x is going to be equal to x prime, and now instead of a v, we have a negative v, right?

So if you subtract a negative v, in fact, let me just write it that way. X minus negative v times t prime, that would be the Galilean Transformation, but whatever lorentz transformation equation factor we used here, there's a symmetry here.

## The Lorentz transform equations, the addition of velocities and spacetime

I shouldn't have to use a different scaling factor if I assume a different, kind of, if I'm in a different frame of reference. Lorentz transformation equation may find it helpful to search within the site to see how similar or related subjects are covered.
