Logical Positivism, Falsificationism & Modern Science Critiques
Logical positivism and falsificationism are two influential philosophies of science that attempt to define how scientific knowledge is formed and validated.
Logical Positivism
Logical positivism (also called logical empiricism) emerged in the early 20th century, primarily associated with the Vienna Circle, a group of philosophers and scientists. It aimed to establish a rigorous, scientific approach to knowledge by emphasizing verification through experience and logic.
Core Principles

Workplace Safety Signals and Essential First Aid Procedures
Signaling Safety
Health and safety signaling refers to an object, activity, or specific situation. It provides an indication or obligation related to safety or health at work through a panel sign, a color, a light or acoustic signal, or gestural or verbal communication signals, as appropriate.
Usage Requirements (Royal Decree 486/97)
The height and placement of signs should be determined in relation to the visual angle and the location. The signal lights must be placed where they can be easily seen.

Evolution of the Spanish Industrialization Process
Delayed Start: 1855-1900
The beginning of Spanish industrialization between 1855 and 1900 occurred later than in other Western European countries due to several factors:
- Spain had a limited supply of certain essential raw materials and energy resources.
- Industrial investment was insufficient.
- There was a lack of strong entrepreneurship.
- Significant technological backwardness existed.
- The external situation was unfavorable (e.g., loss of colonies, instability)
Fundamental Fluid Mechanics Concepts and Definitions
Pascal’s Principle
When pressure is exerted on a liquid in equilibrium, this pressure is transmitted equally to all molecules throughout the fluid.
Turbulent Flow Regime
Characterized by unequal particle movement, where particles collide with each other and against the walls of the conductive element, bouncing off and losing energy.
Full Contraction in a Hole
Liquid streams (fillets) occupy the periphery of a hole and come close to the interior zones. They slide along the walls and have a very strong

IV. The Ambush
It was time to end the lives of the Englishmen. On a Friday in March, late at night, a dim light illuminated the place chosen for the ambush. The wait seemed interminable, but the time finally came. Alatriste and the Italian assassin Malatesta launched themselves upon the Englishmen. Malatesta was about to deliver the mortal blow to one of them but was prevented by Alatriste. He saved the Englishman’s life, disobeying the orders of

Understanding the Learning Portfolio
The portfolio is a personal document, promoted by the European Consensus, in which the user or student learning a language—either within a school context or outside of it—can record their learning experiences, reflect on them, and self-assess using the objective parameters of the European Framework for Languages.
University Competency Portfolio Implementation
The dynamics of using portfolios for competencies at the university level would generally follow these

Nietzsche’s Philosophy: Truth, Morality, and the Superman
Nietzsche’s Critique of Truth and Morality
Nietzsche proposes a critical history, condemning elements that hinder our performance. He argues that truth is a lie originating in language, which, as a social construct, defines what is considered true and false.
The origin of language and knowledge lies in the imagination. The mind creates metaphors, analogies, and models that are then taken as truth. This truth becomes a comfortable lie, accepted by all.
Nietzsche views the human being as precarious,
