Founding our analysis on the Geneva-Brussels approach to the foundations of physics, we provide a clarification and classification of the key concept of observation. An entity can be observed with or without a scope. In the second case, the observation is a purely non-invasive discovery process; in the first case, it is a purely invasive process, which can involve either creation or destruction aspects. An entity can also be observed with or without a full control over the observational process…

God May Not Play Dice, But Human Observers Surely Do
It is shown that by removing the randomness incorporated in certain of the authors' observational processes, acquiring over them a better control, they also alter these processes in such a radical way that in the end they do not correspond to the observation of the same property.
Heisenberg uncertainty principle and the strange physics of spaghetti
This is an article written in a popular science style, in which I will explain: (1) the famous Heisenberg uncertainty principle, expressing the experimental incompatibility of certain properties of
Understanding quantum mechanics: a review and synthesis in precise language
This review is broad in scope, and aims to reflect enough of the literature to be representative of the current state of the subject, and to contribute to achieving greater consensus on how to understand quantum mechanics.
A New Approach for Optimizing Highly Nonlinear Problems Based on the Observer Effect Concept
• Computer Science
• 2019
Performance analysis of the proposed meta-heuristic algorithms based on Observer Effect concepts for controlling memory usage per localities without pursuing Tabu-like cut-off approaches suggests that proposed algorithm is useful both solely and in hybrid Gradient Descent settings where problem's search space is nonhomogeneous in terms of local peaks density.
Comparison of two methodologies for occupational accidents pre-cursors data collection
• 2015
Unsafe acts (UA) and unsafe conditions (UC) are commonly considered as accidents pre-cursors. Several methods can be applied to collect accident pre-cursors in different working environment.
First derivatives at the optimum analysis (fdao): An approach to estimate the uncertainty in nonlinear regression involving stochastically independent variables
An important problem of optimization analysis surges when parameters such as $\{\theta_i\}_{i=1,\, \dots \,,k }$, determining a function $y=f(x | \{\theta_i\})$, must be estimated from a set of
Election Observers and Electoral Fraud
• Economics
• 2013
We use a randomized saturation design to investigate whether domestic election observers reduce electoral fraud in the 2012 presidential elections in Ghana. Results show that observers reduce the
Protecting the Polls: The Effect of Observers on Election Fraud 1
• Economics
• 2013
Do domestic election observers deter electoral fraud? And under what conditions do political parties respond to the presence of observers to negate their impact? We address these questions by

BEING AND CHANGE: FOUNDATIONS OF A REALISTIC OPERATIONAL FORMALISM
The aim of this article is to represent the general description of an entity by means of its states, contexts and properties. The entity that we want to describe does not necessarily have to be a
The entity and modern physics: the creation-discovery- view of reality 1
The classical concept of 'physical entity', be it particle, wave, fleld or system, has become a problematic concept since the advent of relativity theory and quantum mechanics. The recent
Generalization of the proof on the existence of hidden measurements to experiments with an infinite set of outcomes
We generalize Aerts' proof concerning the existence of hidden measurements for experiments withn outcomes to general experiments with an infinite set of outcomes. More specific we prove that, ifɛ is
The δ-Quantum Machine, the k-Model, and the Non-ordinary Spatiality of Quantum Entities
The main ideas at the basis of Aerts’ creation-discovery view and hidden measurement approach are presented: a fundamental explanatory framework whose importance has been seriously underappreciated by the physics community, despite its success in clarifying many conceptual challenges of quantum physics.

It is an unusual pleasure to present Professor Heisenberg’s Chicago lectures on “The Physical Principles of the Quantum Theory” to a wider audience than could attend them when they were originally
Construction of reality and its influence on the understanding of quantum structures
We present a view where the process of detection of existing reality and creation of new reality is considered explicitly, and that rests on the insight that “the present” is operationally connected
Quantum structures, separated physical entities and probability
We prove that if the physical entity S consisting of two separated physical entities S1 and S2 satisfies the axioms of orthodox quantum mechanics, then at least one of the two subentities is a
A possible explanation for the probabilities of quantum mechanics
It is shown that a lack of knowledge about the measurements of a physical system gives rise to a nonclassical probability calculus for this physical system. It is also shown that the nonclassical
Reality and Probability: Introducing a New Type of Probability Calculus ∗
A new type of probability theory is proposed that is a generalization of standard probability theory and makes it possible to define probability on the whole set of experiments within the GenevaBrussels approach to quantum mechanics, which was not possible with the current approach.
