Length Contraction Documentary

Click For Summary

Discussion Overview

The discussion centers around the concept of length contraction in the context of special relativity, specifically seeking video resources that visually explain or demonstrate the phenomenon. Participants express a need for materials suitable for a documentary, exploring both theoretical and observational interpretations.

Discussion Character

  • Exploratory
  • Homework-related
  • Debate/contested

Main Points Raised

  • One participant requests videos that explain or prove the possibility of length contraction, emphasizing the need for visual interpretations.
  • Another participant shares a link to a video that includes content on Lorentz contraction, suggesting it may be relevant.
  • There is a mention of a Terrell-Penrose rotation as a way to understand what an observer sees regarding length contraction.
  • Some participants express skepticism about the usefulness of additional links, suggesting that watching existing videos and asking specific questions may be more beneficial.
  • A participant indicates a desire for videos that include interviews with physics professors or university lectures, rather than general content on relativity.
  • One participant discusses the relationship between time dilation and length contraction, noting that some recommended videos do not directly address length contraction.
  • A suggestion is made to use a specific program related to the topic, although its relevance is not fully explored.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best resources for understanding length contraction, with multiple competing views on what constitutes relevant material. The discussion remains unresolved regarding the specific types of videos that would be most helpful.

Contextual Notes

Some participants express uncertainty about the connection between time dilation and length contraction, indicating that the relationship may not be straightforward. There are also varying opinions on the appropriateness of certain video resources.

Who May Find This Useful

Individuals interested in the visual and theoretical aspects of length contraction, particularly those working on educational or documentary projects related to relativity.

I need help with length contraction.
I need videos that explains or proves that length contraction is possible even if it is just the visual interpretation of an observer.
pls help.

http://video.google.com/videoplay?docid=-6328514962912264988# video was recently posted in another thread. I have only seen a few seconds, but it appears to be what you need. There's some stuff about Lorentz contraction in it. Note that it's part of a series of videos. You might want to check out the others too.

Fredrik has helped with this.

For an explanation of what an observer actually sees (a Terrell-Penrose rotation), read

https://www.physicsforums.com/showthread.php?p=2320863#post2320863.

For images of what an observer sees, click on the two links given by A.T. in post #3 in the same thread.
 
wow, thank you, who is Fredrik? could you please post the link here?
 
See post #2 in this thread. The very first word is a link. :smile:
 
thank you everyone,

not being so demanding, could you please post more links here, i need them badly.

please.
 
I'm not trying to discourage anyone from posting more links to videos, but I don't think more of the same is what you need. You should probably just watch a video or two in that series and then ask questions here about specific details that you found hard to understand.

but, I'm actually looking for videos that i could use for the documentary that i will be making,
it will serve like a proof for the occurrence of length contraction.

i have seen these but i think it's not that related to length contraction, the video is about time dilation.

Fredrik said:


another familiar video, it's about simultaneity, and has almost no connection to length contraction,

Fredrik said:

this video is really a great help, it explains the connection between time dilation and length contraction. It's about the way they measure the length, right? if your clock ticks more slowly than that of the stationary observer, then, at a constant relativistic velocity, you cover a greater distance in a smaller period of time.

Fredrik said:

this explains how the world will look like when you travel at a velocity near the speed of light, it doesn't actually explains how time dilation happens.


Fredrik, thanks for these videos, but most of these are not the ones that I'm looking for, do you have a video wherein there is an interview of a physics professor or a lecture from a university?
thank you in advance.

excuse me, i need more help.
i don't know how to start the documentary.
but i actually thought of something.

i'll start with the introduction,
then after that, i'll be explaining length contraction even more
then, i'll show how the formula was derived
then, show length contraction in different perspectives
then, train paradox
then, the possibility of length contraction.

is this ok already?
please reply right away.
tnx.
