The round trip as an instrument

SLOP8217 · Week 10

Every specimen so far was found.

Producing error deliberately to measure a system you cannot open

This week we make them.

Back-translation is old and mostly used for quality checking, which is not what we are doing with it.

That is a measurement, taken from outside, of something nobody will let us open.

Outline

  • back-translation, and why it is a bad quality check and a good probe
  • convergence: where the fixed point usually sits and why

Outline

  • reading register, length and vocabulary off a fixed point
  • the limits: what a probe from outside can never establish
