This article sheds light on Aristotle's own understanding of philosophy. It tries to give an account of how Aristotle seeks to determine and to explain the origin of philosophy and to account for its early development. It focuses on his account of the history of philosophy from its beginnings down to his own time in Metaphysics 1.3–10, in particular 1.3–6. It derives a good deal of knowledge about early Greek philosophy directly from Aristotle. A great deal of the information provided by later ancient sources itself is derived from Aristotle and his students, like Theophrastus or Eudemus. The evidential value of this information is rather high. It also is clear that Aristotle had his own particular perspective on the history of early Greek philosophy, and that his students largely shared his general view of the early history of Greek philosophy.

Electron Microscopes

By 1940, a half dozen or so commercial or home-built transmission electron microscopes were in use for studies of the ultrastructure of matter. These operated at 30-60 kV and most pioneering microscopists were preoccupied with their search for electron transparent substrates to support dispersions of particulates or bacteria for TEM examination and did not contemplate studies of bulk materials. Metallurgist H. Mahl and other physical scientists, accustomed to examining etched, deformed or machined specimens by reflected light in the optical microscope, were also highly motivated to capitalize on the superior resolution of the electron microscope. Mahl originated several methods of preparing thin oxide or lacquer impressions of surfaces that were transparent in his 50 kV TEM. The utility of replication was recognized immediately and many variations on the theme, including two-step negative-positive replicas, soon appeared. Intense development of replica techniques slowed after 1955 but important advances still occur. The availability of 100 kV instruments, advent of thin film methods for metals and ceramics and microtoming of thin sections for biological specimens largely eliminated any need to resort to replicas.
