All models are not the system that they model.
Original: 'a model is a simplified representation of some part of reality'
All results are provisional.
At sub-atomic level, all models asymptote to Alice-in-Wonderland.
Oh, by the way, we'll need a few more mega-millions to:
- repeat the experiment
- repeat the experiment in different locations
- go back and do the experiment we meant to do in the first place
But we're 'high science', and you'll pay.
All scientists have something loose, and only sometimes is it a cable.
And it's almost Friday.
