Millikan’s oil-drop experiments are justly regarded as a major contribution to twentieth-century physics [1, 2]. They established the quantization of electric charge, the existence of a fundamental unit of charge, and also measured that unit of charge precisely. As Gullstrand remarked in his Nobel Prize presentation speech, “Millikan’s aim was to prove that electricity really has the atomic structure, which, on the base of theoretical evidence, it was supposed to have.... By a brilliant method… 
Millikan's Oil-Drop Experiment: A Centennial Setup Revisited in Virtual World
Early in the last century, Robert Millikan developed a precise method of determining the electric charge carried by oil droplets.1–3 Using a microscope and a small incandescent lamp, he observed the
A non-traditional fluid problem: transition between theoretical models from Stokes’ to turbulent flow
In the context of fluid mechanics courses, it is customary to consider the problem of a sphere falling under the action of gravity inside a viscous fluid. Under suitable assumptions, this phenomenon
The Strong and Weak Senses of Theory-Ladenness of Experimentation: Theory-Driven versus Exploratory Experiments in the History of High-Energy Particle Physics
This article introduces a three-fold distinction among the theories of high-energy particle physics (HEP) as background theories, model theories, and phenomenological models, and distinguishes between the “weak” and “strong” senses of TLE in the context of scattering experiments from the history of HEP.
Carving Nature at Its Joints: Natural Kinds in Metaphysics and Science
Contemporary discussions of the success of science often invoke an ancient metaphor from Plato's Phaedrus: successful theories should "carve nature at its joints." But is nature really "jointed"? Are
Rescuing the Assertability of Measurement Reports
It is wholly uncontroversial that measurements or, more properly, propositions that are measurement reports are often paradigmatically good cases of propositions that serve the function of evidence.
Matters of Fact, and the Fact of Matter
My remarks in this brief commentary focus on Chris Calvert-Minor’s (2014) article on Karen Barad’s philosophical writings, and are only indirectly relevant to an assessment of Barad’s work. I have
Information in an Industrial Culture: Walter A. Shewhart and the Evolution of the Control Chart, 1917–1954
Abstract:This study analyzes the factors that shaped Walter Shewhart’s 1924 development of the control chart at Bell Telephone Laboratories. The control chart is a graphical construct that uses
Communicating uncertain experimental evidence.
Considering the causes of unexpected experimental results in foresight may improve the evaluation and communication of those results in hindsight, according to the participants in four experiments.
Approximate Truth, Quasi-Factivity, and Evidence
The main question addressed in this paper is whether some false sentences can constitute evidence for the truth of other propositions. In this paper it is argued that there are good reasons to
