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. >Space, >Time, >Space-time, >Space-time points, >Reality, >Absoluteness, >Invariance._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
