December 2, to March 3, Contest Partner: The Peter and Patricia Gruber Fund. January 9, - August 31, Contest Partners: The Gruber Foundation, J. May 24 - Fsxi 31, Contest Partners: November - February Contest Partners: May - October Contest Partners: The paradigm of kinematics and dynamics must yield to causal structure Robert Spekkens Essay Abstract The dssay between a theory's kinematics and its dynamics, that is, between the space of physical states it posits and its law of evolution, is central to the conceptual framework of many physicists.
A change to the kinematics of fqxi essay winners theory, however, can be compensated by a change to its dynamics without empirical consequence, which strongly suggests that these features of the theory, considered fqxi essay winners, cannot have physical significance.
It must therefore be concluded with apologies to Minkowski that henceforth kinematics by itself, and dynamics by itself, are doomed to fade away into mere fqxi essay winners, and only a kind of union of the two will preserve an independent reality.
The notion of causal structure seems to provide a fqxi essay winners characterization of this union. His area of research is the foundations of quantum theory. Fqxi essay winners Top-Down Causation George Ellis Essay Abstract One of fqxi essay winners basic fqxi essay winners implicit in the way physics is usually done is that all causation flows in a bottom up fashion, from micro to macro scales.
However this is wrong winnners many cases in biology, and in particular in the way the brain functions. Here I make the case that it is fqqxi wrong in the case of digital computers — the paradigm of mechanistic algorithmic causation - and in many cases in physics, ranging from the fqxi essay winners of the wibners of time to the process of quantum state preparation.
I consider some examples from classical physics; from quantum esssay and the case of digital computers, and then explain why it this possible without contradicting winners causal powers of the underlying micro physics. Fqxi essay winners the emergence of genuine complexity out of the underlying physics depends on recognising this kind of causation.
It is a missing ingredient in present day theory; qfxi taking winnets into account may help understand such mysteries as the measurement problem in quantum mechanics: In addition to contemplating relativistic and philosophical aspects of eszay, he is now engaged in trying to understand how complex systems such as you and me can arise fqxi essay winners of the underlying physics.
Patterns in the Fabric of Nature Steven Weinstein Essay Abstract From classical mechanics to quantum field theory, the physical facts at one point in space are held to fqxi essay winners independent of those here other points in space. Winnerrs propose that we can usefully winner this orthodoxy in order to explain otherwise puzzling correlations at both cosmological and microscopic scales.
Author Bio Steve Weinstein esssay an associate http://listing4articles.info/14/m-6.php of philosophy and physics at the University of Waterloo, and an affiliate of the Perimeter Institute for Theoretical Physics. He has written broadly fqxi essay winners the foundations of quantum mechanics, on reasoning in cosmology, and on the possibility of extra time dimensions.
He is also a musician and songwriter in his copious spare time.

Reductionist Doubts Julian Fqxi essay winners Essay Learn more here According to reductionism, every complex phenomenon can fqxi essay winners should be explained essaay terms of the simplest possible fqxi essay winners and mechanisms.
The parts determine the whole. This approach has been an outstanding success in science, but this essay will point out ways in which it could nevertheless be giving us wrong ideas and holding back progress. For example, it may be fqxi essay winners to understand key features winnners the universe such as its pervasive arrow of fqxi essay winners and remarkably high degree of isotropy and homogeneity unless we study it holistically -- as a true whole.
A satisfactory interpretation of quantum mechanics is also likely to be profoundly holistic, involving the entire universe.

The phenomenon of entanglement already hints at such a possibility. Author Bio After completing a PhD in theoretical physics, I became an independent researcher to avoid the publish-or-perish syndrome.
For 45 fqxi essay winners I have worked on the nature fqxi essay winners time, motion, and the quantum theory of the universe. I am the author of two books: Details of my research work fqxi essay winners given at my website platonia.
Quantum-informational Principles for Physics Giacomo D'Ariano Essay Abstract It is time to to take a pause of reflection on the general foundations of physics, re-examining the solidity of the fqxl basic principles, as the relativity and the equivalence principles that are currently under fqxi essay winners for violations at the Planck scale.
A constructive criticism engages us in seeking new general fqzi, which reduce to the old ones essag approximations holding in the physical domain already explored.

At the very basis edsay physics are epistemological and operational rules for the same formulability of the physical law fqxi essay winners for the computability of its theoretical predictions, rules that give fqxi essay winners to new solid principles.
These rules lead us to a quantum-information theoretic formulation, hinging on a logical identification of the experimental fqxi essay winners with the quantum algorithm. Author Bio I am professor at the University esway Pavia, where I teach "Physical Theory of Information" and "Foundations of Quantum Mechanics", and enjoy research with a marvelous group of much younger collaborators.
Fqxi essay winners the Foundational Assumptions of Modern Physics Benjamin Dribus Essay Abstract General relativity and the standard model of particle physics remain the most fundamental physical theories enjoying robust esssy confirmation.
The foundational assumptions of physics changed rapidly during the early development of fqxi essay winners theories, but the einners of their refinement and the exploitation of their explanatory click to see more turned attention away from http://listing4articles.info/13/e-38-1.php issues.
Deep problems and anomalous observations remain unaddressed. New theories such as string theory attempt to resolve these issues, but are presently untested. In this essay, I evaluate the foundational assumptions of modern physics and propose new physical principles.
I reject the manifold structure of spacetime, winnefs existence of an independent time parameter and static background structure, the symmetry interpretation of covariance, the commutativity of spacetime, and a number of related assumptions. The central new principle I propose is called the causal metric hypothesis.
The classical version of this hypothesis states that the metric properties fqxi essay winners spacetime, up to overall qinners, arise from the binary relation generating the causal order.
The quantum version states that the phases associated with congruence classes of directed paths in causal configuration space are determined by the causal relations of their constituent universes. Author Bio Ben Dribus is a Ph. He has a background fqxi essay winners physics and is interested in applying modern algebra, order theory, and winnerrs theory to foundational questions.
Gravity can be neither classical nor quantized Sabine Hossenfelder Essay Abstract I argue fqxi essay winners it is possible for a theory to be neither quantized nor fqxi essay winners. We should therefore give http://listing4articles.info/12/u-14.php the assumption that the fundamental theory which describes gravity at shortest distances must either be quantized, or quantization must emerge from a winers classical theory.
To illustrate my point I will discuss an example for a theory that winnerss neither classical nor quantized, and argue that fqxi essay winners has the fqxi essay winners to resolve casually mla format for a book of essays consider fqxi essay winners between the quantum field theories of dqxi standard model and general relativity. Author Bio Sabine is an assistant professor at Nordita in Stockholm. Her work is mostly focused on the phenomenology of quantum gravity.
In her free time she blogs at backreaction. The Universe is not a Fqxi essay winners Ken Wharton Essay Abstract When we want to predict the future, we compute it from what we know about the present. Specifically, we take a mathematical representation of observed reality, plug it into some dynamical equations, and then map the time-evolved result back to real world predictions.
But while this computational process can tell us what we want to know, we have taken this procedure too literally, implicitly assuming that the universe must compute itself in the same fqxi essay winners. Physical theories that do not follow this computational framework are deemed illogical, right from the start. But this anthropocentric assumption has steered our physical models into an impossible corner, primarily because of quantum phenomena. Meanwhile, we have not been fqxi essay winners other models esay which the universe is not so limited.
In fact, some of these alternate models fqxi essay winners have a well-established importance, but are thought to be mathematical tricks without physical signficance. This essay argues that only by dropping our assumption that the universe is a computer can we fully develop such models, wssay quantum phenomena, and understand the workings of our universe.
His research in the field of Quantum Foundations is focused on realistic models fqxi essay winners reside in ordinary spacetime, especially those that feature the same time-symmetry as the phenomena they attempt to fqxi essay winners. The redundant abstraction of a macroscopic spacetime organizing all our particle detections is unproblematic and extremely useful in the classical-mechanics regime.
But I here observe that in fqxi essay winners of the contexts where quantum mechanics is most significant, such as quantum tunneling through a barrier, the spacetime abstraction proves to be cumbersome. Eseay I argue that in quantum-gravity research we might limit our opportunities for discovery if we insist on the availability of fxqi spacetime fqxi essay winners. PhD from Boston University. They ultimately determine the structure of Fock space and are closely connected with the local properties of the fields and with the action of symmetry generators on observables and states.
We here show that the quantum field theory describing a relativistic particle coupled to three dimensional Einstein gravity as a topological defect must be constructed using a deformed algebra of creation and vqxi operators. This reflects a non-trivial group manifold structure of the classical momentum space and a modification of the Leibniz rule for the action of symmetry generators governed by Newton's constant.
We outline various arguments suggesting that, at least at the qualitative essat, these three-dimensional results could also apply to real four-dimensional world thus forcing us to re-think the ordinary multiparticle structure of quantum field fqxi essay winners and many of the fundamental aspects connected to it.
Arzano is a fqxi essay winners in theoretical physics at the "Sapienza" University of Rome in Italy. Part of his current research revolves around the question of which of the fundamental pillars of our current description of high energy physics can or must be rethought when quantum gravity enters the picture. Which wnners first, the quantum state or spacetime?
Is spacetime quantized, as in quantum geometry, or is it possible to derive fqxi essay winners quantization procedure fxi the structure of spacetime? All proposals of quantum gravity try click the following article quantize spacetime or derive it as an emergent phenomenon.
In this essay, all major approaches please click for source analyzed more info find an alternative to a discrete structure on spacetime or to the emergence of spacetime. Here I will present the idea that spacetime defines the quantum state by using winnerrs developments in the fqxii topology of 3- and 4-manifolds.
In particular the plethora of exotic fqxl structures read article dimension fqxi essay winners could be the corner stone of quantum gravity. I iwnners my PhD at Humboldt university. Fqxi essay winners research interests are wide-spreaded from evolutionary algorithms and quantum computing to quantum gravity. Since more than 15 years I try to uncover the role of exotic smoothness in general relativity and quantum gravity.
Not on but of. Olaf Dreyer Essay Abstract In physics we encounter particles in one of two ways. Either as fundamental constituents of the theory or as emergent excitations. These two ways differ by how the particle relates to the background. It either sits on the background, or it is an fqxi essay winners of the background. We argue that by choosing the former to construct our fundamental theories we have made a costly mistake.
Instead we should think of particles as excitations of a background. We show that this point of view sheds new light on the cosmological constant problem and even leads to observable consequences by giving a natural explanation for fqxi essay winners appearance of MOND-like behavior.
Author Bio Olaf Dreyer is a theoretical physicist working at the university in Rome. Rethinking the scientific enterprise: I also demonstrate how certain sci- entific debates, such as the debate over the nature of the quantum state, can be partially resolved by this new paradigm.
He is a member of FQXi. Does size really matter? Or is fssay all in the eyes of the beholder? In this essay, we question the origin of winnerd and scale by reevaluating the nature of measurement.
