Relativity #37 - Length Contraction (Spacetime diagram intuition)

We are now one year after the introduction of this series. It is called Relativity. That includes General Relativity. But before we arrive at Einstein's field equation(s) you need to have some patience :-) P.S. I don't think Lula survives this series.

You are making a lot of videos on special theory of relativity when there are a lot of other video series on this topic. why dont you make videos on quantum field theory on which there are almost no video series which can be comprehended unless you are a trained physicist.

If you create a very very very simple geometric representation of the actual physical, meaning what truly is physically going on concerning space-time and the motion of objects that exist within it, you can then use this one piece of geometry alone to derive the time dilation equation, the length contraction equation, the velocity addition equation, and the Lorentz transformation equations, and complete this task in mere minutes. One may do so even if one knows nothing about physics, nor has ever seen any of the equations beforehand. Such a pity that in today's physics SR education, the actual "Physical" of what is going on, is always being 100% ignored. I find that funny, since the SR topic at hand, sits within what is referred to as "PHYSICS".

We can see how much Lula means to you, Whyb, and hope you both are doing well, while knowing she can't live forever. Wishing you all the best and thanks for your fabulous video series.
