Particle Metaphysics: A Critical Account of Subatomic Reality [Hardcover]

Are the particles of modern physics real or are they virtual entities, their existence deduced merely by abstract theories? This book examines the continuing debate regarding the inner constitution of matter by exploring the particle concept in physics. It investigates if the particles of particle physics are real or not. Readers interested in the true meaning of such physical concepts will find this book informative and thought provoking.

Metaphysics, with which, as fate would have it, I have fallen in love but from which I can boast of only a few favours, o?ers two kinds of advantage. The ?rst is this: it can solve the problems thrown up by the enquiry of mind, when it uses reason to spy after the more hidden properties of things. But hope is here all too often disappointed by the outcome. And, on this occasion, too, satisfaction has escaped our eager grasp. [...] The second advantage of metaphysics is more consonant with the nature of the human understanding. It consists [...] in knowing what relation the question has to empirical concepts, upon which all our judgements must at all times be based. To that extent metaphysics is a science of the limits of human reason.[...] Thus, the second advantage of metaphysics is at once the least known and the most important, although it is also an advantage which is only attained at a fairly late stage and after long experience. 1 Immanuel Kant The tradition of the particle concept goes back to traditional metaphysics and ancient philosophy. The idea that matter is made up of microscopic constituent parts stems from ancient atomism. At the very beginnings of modern physics, it was taken up by Galileo, Descartes, and Newton. Newton thought that there are atoms of matter and light, but with the methods of Newtonian mechanics and optics they were beyond the reach of experiments.Scientific Realism.- Extending Physical Reality.- Particle Observation and Measurement.- Probing Subatomic Structure.- MeasurementlăI
