Why is the complex number an integral part of physical reality?

In modern physics, the quantum wave distribution function necessarily uses complex numbers to represent itself. If physics defines the physical reality, then what we are saying by the statement above is that the reality is made up of immeasurable…

What are some arguments against the brain-in-a-vat thought experiment?

I read this article about how this guy in Switzerland did an experiment that he thought proved the Simulation Hypothesis of reality (link: http://arxiv.org/abs/1210.1847). I have also been reading the original philosophy paper by Nick Bostrom…

Are mathematical suppositions of physical theories determined uniquely according to Aristotle and Plato?

Does mathematics apply to physics in one way or multiple ways? What do Aristotle and Plato think? It would seem that Aristotle thinks mathematics can be applied to physics in one way only because, for him, mathematics is abstracted from physical…

Interpretation of the butterfly effect

It is said that in certain circumstances, a tiny change, like the flap of a butterfly's wings, can lead to enormous changes, like a tornado somewhere. However, it should be clarified what "change" means. If the constantly changing state of the…

Are infinities in physics (or in any other materalist philosophy) actually possible?

Aristotle made a distinction between infinities that were in potential (dunamis) and in actuality (energia); and stated that actual infinities did not obtain in the physical world. This is the basis of Kants antinomies of time and space. It has…

What is the "fabric" of spacetime if it is not a relational entity?

This is an interdisciplinary (philosophical physics) question. In Newton's absolute spacetime model, spacetime is described as a physical entity. However, in the relational spacetime model (supported by many including Plato, Aristotle, Descartes,…

Does Popper's theory of falsification apply to mathematics?

Mathematics is generally & popularly judged a science in the basic duality: science - humanities. As enemies and collaborationists. The border heavily & fiercely policed. However, it seems to me that Poppers theory, which entitles science-hood by…

What is the ontological status of information that is permanently inaccessible to any conceivable observer?

Rovelli & others, in Relational Quantum Mechanics (RQM) take the simple ontological picture of the Copenhagen Picture and relativise it. This is what I was suggesting in this question, though I was looking for a specific mathematical treatment. In…

Can the observer be the observed?

As a supplement to this question as to whether particles can be observers, supposing that the answer is yes. One could suppose a setup where particle A is observing particle B, but what to stop us switching viewpoints around here and supposing…

What do Philosophers think about the Many Worlds Interpretation of quantum mechanics?

One of the interpretations of quantum mechanics is the Many Worlds Interpretation which basically states that the universe as a whole develops like an unobserved quantum system, and any observation effects ("collapse of the wave function") are…

Is the idea of a causal chain physical (or even scientific)?

I am aware that the idea is venerable, going back through Lucretius to the Stoics and Epicurus, and even to Aristotle with his prime mover argument. But isn't this a pre-scientific notion? The Atomists thought that collisions cause motion. But…

How can we take the ontologies of our best physical theories seriously?

It seems to me that numerous features of our best physical theories thus far (most notably in my humble and near-meaningless opinion: the whole notion of renormalization in quantum field theory) themselves strongly hint at not taking the ontology of…

Best books on philosophy of physics

I'm looking for recommendations on graduate level books concerning philosophy and physics, or preferably the philosophy of physics. I'm currently reading 'After Physics' by David Albert, and 'The Philosophy of Space and Time' by Hans Reichenbach,…

Is there "empirical" distance without "mathematical" distance?

Mathematicians since antiquity have been thinking about length and angle, including doing things with straight-edges, rulers, compasses, and protractors. Fast-forward to modern physics, and you'll see everything from the Euclidean distance in…

Are "'why' questions" useful in or applicable to the study of science?

Based on the lively discussion of this question over at physics.stackexchange, I thought it might be useful to ask it here as well. The kernel of the debate is whether or not "why" questions are fundamentally metaphysical in nature and, therefore,…
