He looks at her, and she looks away. She thinks he is staring at her flaws, but he is admiring the way the light hits her face. He watches her laugh, and she fidgets her feet. She thinks he sees crooked teeth, but he’s falling in love with the bright soul beneath.
The concepts ‘system’, ‘apparatus’, 'environment’, immediately imply an artificial division of the world, and an intention to neglect, or take only schematic account of, the interaction across the split. The notions of 'microscopic’ and 'macroscopic’ defy precise definition. So also do the notions of 'reversible’ and 'irreversible’. Einstein said that it is theory which decides what is 'observable’. I think he was right - 'observation’ is a complicated and theory-laden business. Then that notion should not appear in the formulation of fundamental theory. Information? Whose information? Information about what? On this list of bad words from good books, the worst of all is 'measurement’. It must have a section to itself.
