Step 1 and 2 perfect , step 3 : at time t=t'=0 , a photon of light leave the Origin O and O', and the Frame F' leave too with velocity V , according step 1.To avoid all complicate Math, let's take real numbers : X' = 1 m. , distance between O and O' Vt' = 2 m . So X = a [ X' + Vt' ] will be equal X= 3a. From X = C t ...t = X : C = 3a:C=3a/C..t = 3a/C...from X' = C t'...t' = X' : C = 1:C=1/C...t' =1/C...From Vt' = 2...V = 2 : t' =2 : 1/C = 2C.... V = 2C . Something is wrong...I use formulas from Video, just take any real number for distance .

Can we really treat a clock which uses pulse of light as stationary clock? The pulse of light is a part of the clock and this pulse is not at rest in any frame; rather it is moving at c. So how can we say that this is a stationary clock?

Why do we assume there is an alpha in the form of these equations at the outset: Why do we assume length contraction at the outset? Isn't length contraction a result of, rather than a reason for the Lorentz equations. So is this a bit circular? Instead, why not assume a more general form i.e. x = Ax' + Bt' etc a priori (i.e. a form that assumes nothing except linearity) and go from there. And similarly for time: t = Cx' +Dt' etc. Then do step one, two and three (but you will need a fourth step where light travels along the y axis also to solve for A,B,C,D). The way you're doing it seems to be a bit of a cheat, because we shouldn't know anything at the outset about length contraction from the two postulates. We only find out about that when we have the Lorentz equations surely. Also, the explanation for x = alpha(x'+vt') from the diagram. I don't quite get this. Assuming the need for an alpha aside, I understand why it could be x' = alpha(x-vt) but not the other way from the diagram. And for the next diagram, I understand how that could be x = alpha(x'+vt') but not what is given here. Are you sure these are correct.

The biggest point in this derivation is in step 3, where you assumed that x'=ct'. I understand that this assumed from the postulate stating that light speed is constant in all inertial frames of reference. Hence x'=ct' and not (c-v)t'. But I fail to understand the basis behind this postulate. I've read on other forums that this proof can be elaborated back from Maxwell's EM equations where if you try to derive the speed of an EM wave in any inertial reference frame, it is constant. Can you please confirm/clarify regarding this?

The fact that the speed of light is constant in all inertial frames of reference has been proved experimentally ( Michelson-Morley Experiment). It is very well explained in Khan Academy videos. www.khanacademy.org/science/physics/special-relativity
@markkennedy97676 ай бұрын
The basis of c being universal is the failure of the Michelson Morley experiment to show the ether exists: Prior to this experiment it was assumed light travelled in a kind of absolute background medium (like mechanical waves do) which scientists called the ether. If this were true one could move through the ether relative to light and we would get a different value for the speed of light (not c). The Michelson Morley experiment tried to demonstrate this by having an apparatus move in different directions through the assumed ether and thereby show that the speed of light varied depending on this movement. It failed to do this. Also, Einstein was more interested in Maxwell's equations which said that Electromagnetic waves move with a speed c in a vacuum irrespective of the motion of the source or the observer.

@brendenglover28466 жыл бұрын
First i suggest looking at the derivation for time dilation, then use that to understand a length contraction derivation. Under the theory of relativity, two different inertial frames will measure lengths differently. So there must be a length contraction factor to translate between to frames. This video then solves for the factor.

What is the difference between lorentz transformation and galelian transformation
@StarShootex7 жыл бұрын
Galilean Transformation is for Newtonian Physics, where the object you're dealing with has a velocity that is no where near the speed of light (ie cars). Lorentz Transformation is for Special Relativity, where the object you're dealing with has a velocity that is very close to the speed of light (eg. A proton at 0.9c, or 90% the speed of light). If you use Galilean Transformation for Special Relativity calculations, you'll almost always end up with an answer that looks like 1.8c, which is impossible - Because nothing can travel faster than 1c. That's why Lorentz equations have a Gamma factor to compensate for this, to bring the answer back down to values below 1c.

@Music_Creativity_Science5 жыл бұрын
Partly agree with Eric Su. This is a very good video, but it does not fully relate to physics. Space is not a variable when moving, two planets do not actually come closer to each when moving fast between them. But time is a physical variable (rate of change in matter), and that Lorentz transformation equation calculates such time dilation correctly. Which means, concerning mathematical space contraction (if that is what he is describing), the moving observer instead physically measures a longer distance per time unit (slowed down rate of change, "longer seconds"), which means measuring a higher velocity. Space distances are the same (fixed for all observers), the measured velocity is higher for a moving observer, due to the physical time dilation effect. Ps. If he is just describing a length contraction in the moving object itself (not any space/distance contraction), that could be physically true during an acceleration/deceleration phase, such a force acting upon matter and deforming it. Trying to reach the speed of light, it would be totally flat in the moving direction, due to infinite acceleration force acting upon it...
