POTENTIAL HISTORY: READING ARTIFICIAL INTELLIGENCE FROM INDIGENOUS KNOWLEDGES*

open access: yesHistory and Theory, Volume 62, Issue 1, Page 3-29, March 2023., 2023
ABSTRACT Until the beginning of the twentieth century, history, as a core concept of the political project of modernity, was highly concerned with the future. The many crimes, genocides, and wars perpetuated in the name of historical progress eventually caused unavoidable fractures in the way Western philosophies of history have understood change over ...

Interesting Examples of Violation of the Classical Equivalence Principle but Not of the Weak One

open access: yesAdvances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
The equivalence principle (EP) and Schiff’s conjecture are discussed en passant, and the connection between the EP and quantum mechanics is then briefly analyzed. Two semiclassical violations of the classical equivalence principle (CEP) but not of the weak one (WEP), i.e., Greenberger gravitational Bohr atom and the tree‐level scattering of different ...

Classical and Quantum Exact Solutions for a FRW Multiscalar Field Cosmology with an Exponential Potential Driven Inflation

open access: yesAdvances in Mathematical Physics, Volume 2018, Issue 1, 2018., 2018
A flat Friedmann‐Robertson‐Walker (FRW) multiscalar field cosmology is studied with a particular potential of the form V(ϕ,σ)=V0e-λ1ϕ-λ2σ, which emerges as a relation between the time derivatives of the scalars field momenta. Classically, by employing the Hamiltonian formalism of two scalar fields (ϕ, σ) with standard kinetic energy, exact solutions ...

Cosmologies with Scalar Fields from Higher Dimensions Applied to Bianchi Type VIh=−1 Model: Classical and Quantum Solutions

open access: yesAdvances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
We construct an effective four‐dimensional model by compactifying a ten‐dimensional theory of gravity coupled with a real scalar dilaton field on a time‐dependent torus. The corresponding action in four dimensions is similar to the action of K‐essence theories.

Time‐Dependent Toroidal Compactification Proposals and the Bianchi Type I Model: Classical and Quantum Solutions

open access: yesAdvances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016
We construct an effective four‐dimensional model by compactifying a ten‐dimensional theory of gravity coupled with a real scalar dilaton field on a time‐dependent torus. This approach is applied to anisotropic cosmological Bianchi type I model for which we study the classical coupling of the anisotropic scale factors with the two real scalar moduli ...

Entre el futuro que ya llegó y el pasado que nunca pasó: diplomacias chaqueñas en el antropoceno [PDF]

open access: yesMana, 2020
Resumen Desde que Crutzen y Stoermer (2000) propusieron llamar “antropoceno” a la época actual, los debates en torno a dicho término han reverberado. Las filosofías y prácticas indígenas chaqueñas y amazónicas que presentaremos en este artículo traslucen
