Is x Equal to x' and t Equal to t' in Lorentz Transformations?

Click For Summary
SUMMARY

The discussion centers on the confusion surrounding the application of the Lorentz transformations in special relativity, specifically regarding the values of x, x', t, and t'. Participants emphasize the need to clarify the source material, specifically referencing "The Special and General Theory" by Albert Einstein. The key formulas discussed include the length contraction and time dilation equations, with a focus on substituting values into the Lorentz transformation equations to derive corresponding time values. The conversation highlights the importance of showing work to facilitate better assistance in solving related problems.

PREREQUISITES
  • Understanding of Lorentz transformations in special relativity
  • Familiarity with time dilation and length contraction formulas
  • Basic algebra for substituting values into equations
  • Knowledge of the significance of variables x, x', t, and t' in physics
NEXT STEPS
  • Study the derivation of the Lorentz transformation equations
  • Learn how to apply the time dilation formula in practical scenarios
  • Explore the implications of the speed of light (c) in relativistic equations
  • Review examples of length contraction and time dilation in real-world contexts
USEFUL FOR

Students of physics, educators teaching special relativity, and anyone seeking to understand the implications of Lorentz transformations in theoretical and applied physics.

TL;DR
Very confusing indeed.. How should I use the First and fourth Lorentz equation to get the t and t’ ??

You will get better and more helpful answers if you would tell us what book you're working from (the historians among us will recognize it but that's not somethng you should count on)and what problem you're trying to solve (we can guess, but again you shouldn't count on us guessing right).

My guess is that you're trying to derive either the length contraction formula or the time dilation formula... but if so you should show your work up to where you got stuck and we can help you past the hard spot.
 
This book is available online. The photos in the OP are from https://www.bartleby.com/173/12.html. The first and fourth equations referred to are in the previous chapter, and are the ##x## and ##t## transforms. This is all information you really should have given in your first post.

All you are being asked to do is substitute the given values ##x## and ##t## into those formulae to get the corresponding ##t'## values. I don't see what's difficult about that. If that's not what you are trying to do, you need to explain more.

I’ve been looking for the value of x and t but in the passage they only give the value of x’ and t’. Or is it actually the same value for both x and x’, and, t and t’? So i cannot derive the formula and get the equation in the passage. My confusion is in the passage:
“The first and fourth equations of the Lorentz transformation give for these two ticks: t=0 and t’= one over square root of one minus v square over c square.”

I think its the time dilation formula because it involves the two ticks of a clock. But i’m new to this, so i was hoping that someone could give an explanation as to the purpose of the Lorentz Equation and the way to derive the formula to get the equation of the two ticks.

Its from the book “The special and general theory by Albert Einstein”

##x=0##, ##t=0## and ##x=0##, ##t=1##. It says so in your first picture.
