# Explain how postulates are synthesized into Special Relativity?

## Homework Statement

[/B]
List two postulates of special relativity and then in your own words explain how these two statements are synthesized in Einstein's theory.

## Homework Equations

1. The laws of physics are the same in all inertial reference frames.
2. Light propagates through a vacuum with a speed C, no matter the state of motion other light source.

## The Attempt at a Solution

To my understanding Einstein's theory is already comprised of these two postulates. I am not understanding how to explain the synthesization.

Special relativity incorporates things such as time dilation, length contraction, etc. If I had to guess, I would say you are supposed to make the connection from (c is constant in all inertial frames) + (physics is physics in all inertial frames) ##\to## time dilation, for example.

C and the laws of physics are they same in all inertial frames BiGyElLoWhAt

If I say c is the same in all inertial frames, how does that lead to time dilation? Think light clock.

I was giving you the answer to my question, i found it. You were right as well. I'm lost when you mention time dilation
