The offprint contains the text of the First Baker Lecture, given by Thomson at Cornell on Tuesday, October 8, 1929. The Baker lectures are "The oldest and one of the most prestigious series of endowed lectures sponsored by a chemistry department at an American university."(Cornell website) Thomson took great pains to explain his work and the quandry's it posed in terms that the average person could understand.
"Prof. L. M. Dennis, head of the Department of Chemistry, in explaining the nature of Professor Thomson's lecture made the following statement: "If a speck of dust could be sufficiently magnified, the science of chemistry has shown that it would appear as a cloud of atoms. Physics has demonstrated that every atom has parts — electrons. What are these electrons? Are they Just points, or have they an extended form? Professor Thomson will explain some recent researches which try to answer these questions and which point to the curious result that waves form a fundamental basis for the structure of the world."
