But the hourglass, measuring time by dripping sand, comes late in our story. Sand was, of course, less fluid than water, and hence less adapted to the subtle calibration required by the v...

 Do Not Extrapolate Macro-Philosophy from Quantum Phenomena

Many scientists have tried to make determinism and complementarity the basis of conclusions that seem to me weak and dangerous; for instance, they have used Heisenberg's uncertainty principle to bolster up human free will, though his principle, which applies exclusively to the behavior of electrons and is the direct result of microphysical measurement techniques, has nothing to do with human freedom of choice. It is far safer and wiser that the physicist remain on the solid ground of theoreti...

Globed from the atoms falling slow or swift I see the suns, I see the systems lift Their forms; and even the systems and the suns Shall go back slowly to the eternal drift.
