Title: Time and its arrow: an empiricist's perspective
Authors: Stephen Boughn
Abstract summary: The paradox of the arrow of time arises because the laws of physics are invariably time reversal invariant. The implicit assumption is that time is an ontological property of nature. I conclude that the paradox of the arrow of time is an artificial problem that needs no resolution.

Abstract: The nature of time has beguiled philosophers for nearly three millennia. There are myriad types of time including cosmological time, biological time, psychological time, physical time, historical time, and even theological time. My brief essay concerns time in physics and I hope that the pragmatism of an experimental physicist might help provide a perspective that is often absent in treatises by contemporary philosophers and physicists. This is especially the case for the notion of the arrow of time. The paradox of the arrow of time arises because the laws of physics are invariably time reversal invariant, in which case we are led to ask what determines the direction of time. Investigations of time's arrow are usually framed in the context of a mathematical formalism where the parameter t represents time, and then proceed to logical analyses of how the direction of time emerges. The implicit assumption is that time is an ontological property of nature. On the other hand, for an empiricist like me, it is absolutely crucial to frame any such discussion in terms of direct human experience and not on a parameter in a mathematical model. This, in short, is the motivation for my essay and I conclude that the paradox of the arrow of time is an artificial problem that needs no resolution.

Extralonger: Toward a Unified Perspective of Spatial-Temporal Factors for Extra-Long-Term Traffic Forecasting [69.4265346261936]
We introduce Extralonger, which unifies temporal and spatial factors. It notably extends the prediction horizon to a week on real-world benchmarks. It sets new standards in long-term and extra-long-term scenarios.

Creative and geometric times in physics, mathematics, logic, and philosophy [0.0]
We propose a distinction between two different concepts of time that play a role in physics. The former is the time of deterministic physics and merely parametrizes a given evolution. The latter is instead characterized by real change, i.e. novel information that gets created when a non-necessary event becomes determined.

The Arrow of Time is Alive and Well but Forbidden Under the Received View of Physics [0.0]
The "Arrow of Time Problem" asserts that the empirically observed directionality of time is in conflict with physical theory. I argue that there is actually no necessary conflict between physics and the arrow of time.

Time and Evolution in Quantum and Classical Cosmology [68.8204255655161]
We show that it is neither necessary nor sufficient for the Poisson bracket between the time variable and the super-Hamiltonian to be equal to unity in all of the phase space. We also discuss the question of switching between different internal times as well as the Montevideo interpretation of quantum theory.

An Introduction to time generation on Algebraic Quantum Field Theory [0.0]
In the early 2000s, the study of time operators advanced as one of the methods to understand the problem of time as mathematical science. The starting point for the time operator is to understand time as a problem of observation. Regarding the generation of time, symmetry breaking in particle physics seems to be closely related.
