An Appraisal of the Controversial Nature of the Oil Drop Experiment: Is Closure Possible?
Acceptance of the quantization of the elementary electrical charge (e) was preceded by a bitter dispute between Robert Millikan (1868–1953) and Felix Ehrenhaft (1879– 1952), which lasted for many years (1910–25). Both Millikan and Ehrenhaft obtained very similar experimental results and yet Millikan was led to formulate the elementary electrical charge (electron) and Ehrenhaft to fractional cha...
متن کاملThe Oil Drop Experiment: A Rational Reconstruction of the Millikan-Ehrenhaft Controversy and Its Implications for Chemistry Textbooks
Research in science education has recognized the importance of history and philosophy of science. Given this perspective, it is important to analyze how general chemistry textbooks interpret Millikan’s oil drop experiment. This study has the following objectives: (a) elaboration of a history and philosophy of science framework based on a rational reconstruction of experimental observations that...

layer is not altered by a five-hundred fold change in the surrounding pressure. Further evidence for believing that a condition characteristic of the metal itself has been reached is furnished by the fact that the photoelectric sensitivity of an outgassed specimen remains constant for twelve hours after heat treatment. The work of Davisson and Germer9 on electron reflection from nickel is also ...
متن کاملPresuppositions and Information Updating Presuppositions and Information Updating
Presupposition failures are errors occurring during the left-right processing of a computer program or natural language text. A general method for analysing such errors with dynamic logic is presented, based on the idea that sequential processing changes context dynamically and that this process of context change can be made the object of analysis in dynamic modal logic.
متن کاملPresuppositions, provisos, and probability
Theories of presupposition in the tradition associated with Karttunen, Stalnaker and Heim relate presupposition satisfaction to the content of conversational participants’ epistemic states, usually modeled as sets of worlds. However, converging evidence from recent work on modality and from other areas of cognitive science suggests that epistemic states are better thought of as having the riche...
