  1. Introduction to special relativity and Minkowski spacetime …

    Including multiple observers in the "most obvious" way led to some problems. Let's see how we can start to solve those problems by introducing (what we'll later call) Minkowski spacetime …

  2. Angle of x' axis in Minkowski spacetime (video) | Khan Academy

    When you trace a path of an object moving at a constant rate in a Minkowski spacetime diagram you have a line. The angle of this line depends on the velocity of the object's velocity.

  3. Scale of the universe | Cosmology and astronomy - Khan Academy

    Starting to set up a Newtonian path–time diagram Visualizing multiple Newtonian path–time diagrams Galilean transformation and contradictions with light Introduction to special relativity …

  4. Measuring time in meters in Minkowski spacetime - Khan Academy

    This concept is central to Einstein’s theory of relativity, where space and time are part of a unified spacetime fabric, allowing time to serve as a meaningful measure of spatial separation under …

  5. Introduction to the Lorentz transformation - Khan Academy

    So we've got two coordinate systems from the perspectives of two observers. How can we convert spacetime coordinates between these? Enter the Lorentz transformation!

  7. Khan Academy

    Jan 18, 2016 · Including multiple observers in the "most obvious" way led to some problems. Let's see how we can start to solve those problems by introducing (what we'll later call) Minkowski …

  8. Galilean transformation and contradictions with light

    Jan 18, 2016 · So something has got to give. This is breaking down our classical, our Newtonian, our Galilean views of the world. It's very exciting. We need to think of some other way to …

  9. Въведение в Специалната теория на относителността и …

    Включването на няколко наблюдателя по „най-очевидния“ начин доведе до няколко задачи. Да видим как да започнем да решаваме тези задачи, като въведем (както ще ги наречем …

  10. Starting to set up a Newtonian path–time diagram - Khan Academy

    But now in the next video, we're gonna use this, what I just drew, to draw her frame of reference, to draw a coordinate system, or I guess you could say a space time diagram for her frame of …
