Why did the new physics force out the old?

The aim of my paper is to demonstrate that Special Relativity and the early quantum theory were created within the same programme of statistical mechanics, thermodynamics and Maxwellian electrodynamics. I shall try to explain why classical mechanics and classical electrodynamics were “refuted” almost simultaneously or, in other words, why the quantum revolution and the relativistic one both took place at the beginning of the 20th century. I shall argue that the quantum and relativistic revolutions were simultaneous since they had a common origin—the clash between the fundamental theories of the second half of the 19th century that constituted the “body” of classical physics. The revolution's most dramatic point was Einstein's 1905 photon paper that laid the foundations of both special relativity and the old quantum theory. Hence the dialectic of the old theories is crucial for theory change. Later, classical physics was forced out by the joint development of quantum and relativistic sub‐programmes. The title of my paper can be reformulated in Bruno Latour's terms: The Einstein Revolution or Drawing Models Together.     

The fundamental laws of physics can tell the truth

Nancy Cartwright's arguments in favour of phenomenological laws and against fundamental ones are discussed. Her criticisms of the standard covering‐law account are extended using Vyacheslav Stjopin's analysis of the structure of fundamental theories. It is argued that Cartwright's thesis (that the laws of physics lie) is too radical to accept. A model of theory change is presented which demonstrates how the fundamental laws of physics can, in fact, be confronted with experience.
