The trend is your friend 'til the bend at the end
A Fragment by Noah SmithIn the past, GDP and resources use have always been tightly correlated. But this is just drawing a line through some data — it’s not based on any deep theory. And in fact, these correlations can change very quickly. Just as one example, here’s energy use versus GDP since 1949.
If you were sitting in 1970, you could look at this curve and claim, very confidently, that economic growth requires concomitant increases in energy use. And you’d be wrong. Because the trend is your friend til the bend at the end.
The Interpretation of Microstructures of Metallic Artifacts
The meaning of objects
The meaning of objects is harder to grasp than that of words.
Something akin to style
My own attitude toward the microstructure of metals is not unlike that of an art historian regarding a painting or sculpture. There is something akin to style even in a photomicrograph. There are aspects of structure that are not immediately apparent to the untrained eye, and quite minor features may be clues to a deep meaning.
From the head of Jove
A complex structure is a result of, and to a large extent a record of, its past. Though a proton and an electron may, as a pair, be able to spring full-panoplied from the head of Jove, more complex things cannot, or at least do not.
Everything complicated must have had a history, and its internal structural features arise from its history and provide a specific record of it. One might call these structural details of memory “funeous,” after the unfortunate character in Borge’s story “Funes the Memorious” who remembered everything.
The objects themselves speak loudly
The written record is very little help in determining the techniques used by ancient metalworkers, though the objects themselves speak loudly to an educated ear.
The way it has been made
The internal structure of a work of art in metal can often throw as much, or more, light on its origin as can be derived from stylistic analysis. Moreover, the techniques employed can provide clues to the habits of mind of the people who originated them.
…Perhaps the most important reason for structural studies of museum objects is that the intimate knowledge so derived as to the way in which an object has been made adds so greatly to the aesthetic enjoyment of it. Very often some detail and sometimes the whole of an effective design arises directly in the exploitation of the merits and the overcoming of the difficulties of a specific technique, in the reaction between the artist’s fingers and his material.
Aesthetically motivated curiosity
It seems that the first and most imaginative use of practically every material was, before quite modern times, in making something decorative. People are experimentally minded when looking for decorative effects, but they can’t experiment with the established techniques on which their livelihood depends.

It is of basic significance for human history that, from the cave paintings on, almost all inorganic materials and treatments of them to modify their structure appear first in decorative objects rather than in tools or weapons necessary for survival. Aesthetically motivated curiosity, or perhaps just play, seems to have been the most important stimulus to discovery.
