Karl Pearson. "On the Terminology of the Mathematical Theory of Elasticity", in Nature, 19 March 1885, volume 31, pp 456-457, being two full columns or about 1,000 tightly-packed words. In the weekly issue, removed from a larger bound volume. Very good copy. $100
It begins: "THE late Dr. Todhunter left, in an incomplete state, a valuable “History of the Mathematical Theories of Elasticity,” which the syndics of the Cambridge University Press have intrusted to me to complete and edit. In reading the great number of memoirs relating to the subject I have been much struck by the want of a clear and accurate terminology in both theoretical and practical elasticity. I have been forced to the conclusion that the great discrepancy, which is often to be found between theoretical and practical results, is in some measure due to the want of this terminology (e.g. the extreme looseness of the term “limit of elasticity”). I find it needful for the purposes of the above work to adopt such a terminology, but before doing so it would be extremely valuable to have the opinion of some of our leading elasticians on the terms I venture to propose. I should be very glad of any suggestions, through the columns of NATURE, towards a definite and uniform terminology..."
