1897 Proc. Royal Soc. 61 397 Micro-physical structure of pure gold.

1902 C. R. Mann & R. A. Millikan tr. P. Drude Theory of Optics p. vii Pure electromagnetic experiments lead to conclusions in what may be called the domain of macrophysical properties only. For the explanation of optical dispersion a hypothesis as to the microphysical properties of bodies must be made.

1962 S. E. Toulmin in Quanta & Reality 16 In the macroscopic world, all statistical statements..report the overall aggregates or averages of large numbers of individual events..; but the microphysical statements of quantum mechanics were statistical in a more absolute sense.

1990 J. Gribbin & M. Rees Cosmic Coincidences (1992) p. xiii The dark matter that dominates the Universe is probably in the form of myriads of tiny particles whose individual properties can be understood only in microphysical terms.
