Physically Observable Cryptography [PDF]
, 2004 Complexity-theoretic cryptography considers only abstract notions of computation, and hence cannot protect against attacks that exploit the information leakage (via electromagnetic fields, power consumption, etc.) inherent in the physical execution of any cryptographic algorithm.

Scientific Reports, 2022 A signature invariant geometric algebra framework for spacetime physics is formulated. By following the original idea of David Hestenes in the spacetime algebra of signature $$(+,-,-,-)$$ ( + , - , - , - ) , the techniques related to relative vector and ...

An epistemological and bio-physical point of view on complex systems
Science & Philosophy, 2021 In this article, after a historical introduction, we give an epistemological point of view of the physics of complex systems. Complex systems are epistemologically interesting because of the fundamental interaction experiment/observer and physicists in ...

The Observer Is, by Necessity, the Complete Foundation to Physics
, 2021 While there exist in the wild a process to derive the laws of physics ---namely, the practice of science--- it has never been completely formalized within mathematics. Here, we understand this lack as an unrealized opportunity to source the foundations of physics while remaining mathematically precise.

The Minkowski metric in non-inertial observer radar coordinates
, 2004 We give a closed expression for the Minkowski (1+1)-dimensional metric in the radar coordinates of an arbitrary non-inertial observer O in terms of O's proper acceleration.

Observational and Physical Classification of Supernovae [PDF]
, 2016 This chapter describes the current classification scheme of supernovae (SNe). This scheme has evolved over many decades and now includes numerous SN Types and sub-types. Many of these are universally recognized, while there are controversies regarding the definitions, membership and even the names of some sub-classes; we will try to review here the ...

Quantum-mechanical twin paradox
New Journal of Physics, 2016 In the twin paradox of special relativity, an observer that travels along an accelerated trajectory at a high velocity will experience a smaller amount of elapsed time than an observer that remains at rest. This illustrates the fact that time is relative

Features and new physical scales in primordial observables: Theory and observation [PDF]
International Journal of Modern Physics D, 2015 All cosmological observations to date are consistent with adiabatic, Gaussian and nearly scale invariant initial conditions. These findings provide strong evidence for a particular symmetry breaking pattern in the very early universe (with a close to vanishing order parameter, ϵ), widely accepted as conforming to the predictions of the simplest ...

A Relativistic Theory of Consciousness
Frontiers in Psychology, 2022 In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental
