Visualization of Einstein's special relativity [HD]

This is a remake of my video from 2008, rendered in HD, with narration and minor changes.

This video demonstrates the effects of Einstein's special relativity on objects that move at high velocities due to the Lorentz transformation.

The Lorentz transformation was already known a few years before relativity, but mostly in attempts to justify the classical conception of Ether and absolute space.

The theory of relativity was created based on two principle:
* The principle of relativity: there's no absolute space, and physics works equally correct for different observers.
* Light speed is a fundamental property of physics.
From these two the Lorentz transformation follows as the only possible transformation.

The video shows a 3-dimensional view containing 2 dimensions of space and one dimension of time.

One thing i would recommend to videos like this with slow stable panning animations is to render it at 120fps and encode the video as 60fps to avoid jitter and trembling. It's hard to watch certain parts of it at low framerate. Since this is all simple 3D renders i don't think i changes anything about the workflow other than having to wait a bit longer for the video to export.

This was a topic that took me longer than I'd like to admit to understand the first time I was learning it, and this video makes spacetime diagrams so easy to comprehend. 10/10

I've never been more excited to see a 14 year old video, now in HD

[jaydenchan]

I never expected anyone to visualise special relativity in such concise way and you have blown my mind away !

Back again. Now that I'm deeper into SR at uni, I realise how good this explanation is. At 2:42, the way the animation is used to describe length contraction and time dilation AND relative simultenaity is frankly perfection

Awesome. A static spacetime diagram is so hard to wrap your head around, but this animation makes it feel obvious. Wish this was included in every video I had watched on the matter before..

Only true udiprod fans know that this video is a remastered version of one they uploaded almost 15 years ago! Amazing work guys, keep it up ❤

[alboris]

This channel is crazy bruh how do you make such complicated concepts so simple. Amazing

[SkyGrel]

I just don't understand why noone in my school can explain things like this, and i have to figure out everything by myself. Thank you for this amazing visualization!!

[Ascyt]

Was wondering about something similar before, can't stress enough how thankful I am for you posting this video!!

[TimJSwan]

I am so glad that you redid this video in HD! Your old one was actually still my "go to" for explaining SR to people and I found this while looking it up. Great!!

[terminallywell]

This was one of my favorite videos of yours, I'm glad you guys did a remake!

[SciStone]

awesome stuff, only the last overlayed animation was a little hard to look at

I wonder if the drummer is getting tired of carrying that drum kit yet.

[ghostpoint]

i dont care about science at all, but i just find a lot of joy in these videos.

Don't know how to break it to you guys but the concept of something being different in every case yet somehow the same to each observer, from their "relative" point of view, is a video game thing.

This is how simulated worlds works.

Also notice that from the ground's frame of reference, over time, the amount of photons reaching both detectors is the same. Is the same to throw more balls at lower speed, & throw less balls at higher speeds. These videos are hidden gems of the internet, & we should treasure them as such :D

[eudnen]

Nicely done! This fascinates me not only about the topic itself, but how this channel easily breaks down meticulous topics.

[Tylorean]

How can it be that you explained something to me in 4½ minutes my teachers couldn’t in ¼ year?

[Poptartg]

Oh man, It's been a long time since I saw this! Glad you got to clean it up a bit.
