relationship between physics and philosophy

Some physicists are drawn into their profession from the beginning because they have been convinced by a few revealing examples that the procedures of physical investigation help to achieve perspective, connections, and depth of explanation. For instance, in his recent NYT review, Albert seems to have a realistic interpretation according to which a quantum field is a kind of “stuff” over and above its particles; I found this odd, and struggle to understand how someone who knew, say, Weinberg’s QFT textbook, could just assume this. He just did not see how to make progress on them. So which is it? But without an answer, we really have no understanding of the vacuum state, or the status of “virtual particles”. A few thoughts from a nonphilosopher who went to philosophy grad. the relation between philosophy and science.1 I will start by outlining a general view of philosophy, and afterwards consider philosophy of science. Change ), You are commenting using your Google account. a complex function on another mathematical object called “configuration space”—that is employed in physics as a representation of a physical system. Come to think of it, I remember once talking to a famous string theorist about John Norton’s “Dome.” He genuinely thought it was “sad” (his word) that someone would “waste their time” thinking about this issue when there were so many more interesting things to do (e.g. ( Log Out /  And that’s not to mention all the many metaphysicians who seem to assume a roughly Newtonian world (“imagine all the electrons in my body were replaced with the electrons in your body”). Once the photon has been detected, its red shift can be viewed as a purely relativistic effect produced by the difference in motion between the rest frames of the emitting particle and the detector, and is thus energy conserving. 1. But it is a sociological fact that while it is perfectly acceptable and even expected to discuss questions like this in a philosophy department, or a philosophy course, it can be rare, or even frowned upon, to discuss them in a physics department or physics course. My sense is that at least some of the figures you mentioned are more involved with Algebraic QFT than with the standard QFT that physicists use. The philosophical idea here is something like fallibilism, or that our current best theories are merely provisional. 3) My own sense is that physicists are very open to speculative ideas that I would consider philosophical: for instance, the idea (not provable at present) that local gauge invariance explains why we have the photon field, or the laws of electromagnetism; or the idea that we have the particles we do because of some SO(10) GUT group, or the shape of some extra dimensions. © 2020 Springer Nature Switzerland AG. I (and I hope others) would be interested in some discussion of issues in the history of philosophy/physics where collaboration did pay off (even if is just Einstein collaborating with himself!) I hold graduate degrees in physics, in theoretical economics, and in philosophy, and I have graduate-level familiarity with models of mathematical population genetics. Philosophy of science focuses on metaphysical, epistemic and semantic aspects of science. Where virtual particles account for static fields or near-field effects, the particles are observed by the other systems affected by the fields or effects. The Axioms of Induction, Part 1.

Anyway, the blog is open for successful past and current collaborations (and also unsuccessful ones). An unfortunate controversy has been unfolding the last few weeks over the relationship (or lack thereof) between physics and philosophy. The status of the quantum state of the universe as mathematics or “stuff” questioned above by Barry Loewer and the issue of the nature of the vacuum state raised by Tim Maudlin are two such examples. For example, there is no unique vacuum state, since the state of the vacuum is only defined relative to its potential observing systems, including any particles that might be created and annihilated. The basic relationship between philosophy and education can be analysed as follows. That may arise from studying logic, and indeed be traced to a philosophy background. The issue was raised by Carroll and Smolin and Krauss himself  of exactly what the relationship between physics and philosophy of physics can be and should be. For me it’s easy to see what philosophers often lack, and it’s something like: a working knowledge of the content of field theory textbooks (along with the associated math). These are philosophers from the start. Thus, while interesting in its own right, RQM also serves as a good example of the synergy between philosophical and physical reasoning in advancing our understanding of the universe. As for the apparent non-conservation of energy for CMB photons, in RQM the photon is not considered to have a unique QM state unless it is observed. Others, while surely familiar with QFT, manage to convey a fairly idiosyncratic understanding of the subject. Dirac appreciated the Class One problems, and saw that they are problems. Humanities, sciences and math are the main components of the modern theoretical and practiclal world. A physicist could, for example, believe that philosophy is irrelevant to physics, but not to ethics. But where physics … Create a free website or blog at WordPress.com. This discipline overlaps with metaphysics, ontology, and epistemology, for example, when it explores the relationship between science and truth. Take the case of the “nature of the wavefunction”, for example. I propose the following: philosophy is the systematic search for perspective, for connections among aspects of the world, and for depth of explanation. This is where the lines between philosophy, theoretical and mathematical physics can get most blurry. For example, Einstein’s great interest in the philosophy of Mach was hugely important, yet Mach’s trenchant opposition to atomism on philosophical grounds cannot be denied, nor indeed his opposition to relativity (which became clear after his death, much to Einstein’s dismay).

It would be really good to see more collaboration between physicists and philosophers on this issue. (As an example of the latter, should the physical state of the system correspond to vector or a ray in a Hilbert space? Every state in RQM defines the relationship between two physical objects, the system and the observer. Science has a massive impact on everyone.

Philosophy of physics is just a continuation of physics by different means. For example, physicists make proposals about what laws and chances there are while philosophers of physics are interested in what laws and chances are. > > Albert Einstein, Letter to Robert Thornton, 1944 … These jobs properly belong to philosophy. It aims to explain what happens in our “black box” and how these events affect our way of acting, considering the stimuli we receive too. But somehow it seems like this is not what you’re looking for — perhaps the sense of “philosophy” that’s relevant to your question is not “grand speculative ideas” but something more like “the careful drawing of distinctions taught in philosophy grad. , there are some particular questions that interest philosophers the product of philosophy grad ”! the results experiments!
