Abstract Who’s the greatest of them all? A non-technical explication of Newton’s method in the Principia accompanied by some philosophical reflections In this essay, I seek to explicate the methodology which Newton used in the Principia in a non-technical way. Close attention will be paid to some important results in Books I and III of the Principia and to Newton’s argument for universal gravitation. Based on their discussio Read More

Abstract Alfred Wegener’s Theory of Continental Drift and its Rivals. Rational Disagreement and Rational Consensus in the Earth Sciences Alfred Wegener launched the idea of continental drift (lateral motion of continents on the earth) early in the 20th century. In the period 1915-1930 he did not succeed to convince his fellow earth scientist to leave behind their old permanentist or contractionist theories and adopt his new the Read More

Abstract Promises and disappointments of artificial intelligence for scientific discovery Recent successes within Artificial Intelligence with deep learning techniques in board games gave rise to the ambition to apply these learning methods to scientific discovery. This model for discovering new scientific laws is based on data-driven generalization in large databases with observational data using neural networks. In this study Read More

Abstract How Galileo Galilei discovered the law of fall, and the difference that this makes Galileo’s law of fall is one of the crucial building blocks of classical mechanics. The question how this law was discovered has often been a topic of debate. This article offers a reconstruction of the developments within Galileo’s research that led to the discovery of the law. This reconstruction is offered to make a philosophical point r Read More

Abstract Gregor Mendel, Thomas Hunt Morgan and experiments in classical genetics In the middle of the 19th century, Gregor Mendel performed a series of crosses with pea plants to investigate how hybrids are formed. Decades later, Thomas Hunt Morgan finalized the theory of classical genetics. An important aspect of Mendel’s and Morgan’s scientific approach is that they worked in a systematic, experimental fashion. B Read More

Abstract How certain is Heisenberg’s uncertainty principle? Heisenberg’s uncertainty principle is at the heart of the orthodox or Copenhagen interpretation of quantum mechanics. We first sketch the history that led up to the formulation of the principle. Then we recall that there are in fact two uncertainty principles, both dating from 1927, one by Werner Heisenberg and one by Earle Kennard. Finally, we explain that recent Read More

Abstract Kurt Gödel’s incompleteness theorems and the limits of knowledge In this paper a presentation is given of Kurt Gödel’s pathbreaking results on the incompleteness of formal arithmetic. Some biographical details are provided but the main focus is on the analysis of the theorems themselves. An intermediate level between informal and formal has been sought that allows the reader to get a sufficient taste of the te Read More
