Richard Feynman on Geometry - Dictionary of Arguments

I 247
Measuring/Geometry/Feynman: there are properties that are independent of the particular type of measurement. For example, the distance between two points in a rotated coordinate system when one of the two points is in the origin.
The square of the distance is x² + y² + z².
What about space-time?

Space-Time/Geometry/Feynman: it is easy to show that there is also an invariance here:
I 248
The combination c²t² x² y² z² is the same before and after the transformation:

c²t' ² x' ² y' ² z' ² = c²t² x² y² z².

Ontology/Feynman: this quantity is something that like distance is "real" in a sense. It is called the Def "interval" between two space-time points.
