The questions in this compilation range from the general (e.g., that religion has typically impeded the progress of science) to the specific (e.g., that the Millikan
oil-drop experiment was simple and straightforward) and are organized into four sections: Medieval and Early Modern Science, Nineteenth Century, Twentieth Century, and Generalizations.
One such example is the famous Millikan
oil-drop experiment. This experiment requires the combination of several components that can be dangerous and expensive.
Harvard mathematician Scott Hotton produced a model based on Douady and Couder's
oil-drop experiment. The model shows how the forces in that experiment--designed to mimic the motion of primordia--indeed produce golden-angle spirals.
