- What are events and spacetime?
- What are world lines?
- Simple spacetime diagrams
- How does the inseparability of space and time influence their perception by observers?
Most of the illustrations in the last article used rotations, but it turned out eventually that rotations aren't the correct transformations that would let us look at the spacetime from the point of view of different observers. Now we will take a look at transformations that actually describe reality - the Lorentz transformations.
