Physics Lab Practices: Reaction Time, Density, Energy, Pendulums, Inertia, and Oscillation
Practice 1: Random Errors, Determination of Reaction Time
We know that the fall of a body is accelerated motion, with a relationship between the distance traveled and time. So, it is possible to determine the time it takes to react to stimuli, trying to catch a falling body by measuring the area it runs through before catching it.
- Medium-haul space: The sum of all measures / number of measures +/- error.
- Absolute error: Given by the measurement equipment.
- Relative error: |Δe| / |e|.
- Random error: (1

Thomas Aquinas and Augustine
Saint Thomas Aquinas and Saint Augustine are part of both the scholastic and the patristic traditions. In the conflict between faith and reason, faith prevails in Saint Augustine, but two alternatives are presented. One is the *credo ut intelligam*: “I believe in order to understand.” First, I believe to understand later if I can demonstrate it with reason. The other is *credo ut intelligam*: reason to understand the truth given to us by faith.
Anselm and Aquinas
Both belong

Human Action: Freedom and Responsibility
Human Action
Approach to the Human Being
Operations are conscious and voluntary for the agent.
Specificity of Human Action
- Animal Behavior: The actions of animals are conditioned by their instincts.
- Behavior of a Computer: Their actions are defined by software.
-
Behavior: It is a voluntary agent because their behavior is spontaneous and not inherited. Therefore, the term “action” will address the human.
Individual Action and Collective Action

Neoclassical and Romantic Theater: From Moratín to Lorca
The Neoclassical Theater
Primary Function: To find forms of human behavior that are fairly straightforward. It reflects the current figure: having to accept everything that has happened for some reason, everything I do has to pass by reason, but we need to make things happen. Do not believe in fate, or letters, or chance, it must act reasonably.
Key Features of Neoclassical Theater
- Plausible: It is close to reality; it must reflect reality in environments close to the author or viewer.
- Separation of
Primary and Secondary Data Sources: Collection Methods
Primary and Secondary Data Sources
Primary Source
Definition: Data collected directly from the original source.
Description: First-hand data gathered specifically for the current investigation.
Example: Surveys, interviews, and experiments conducted by the researcher for their own research purpose.
Secondary Source
Definition: Data that already exists and was collected for a different purpose.
Description: Second-hand data gathered by others and used for a new analysis.
Example: Reports, academic papers,
Read MoreMarxism vs. Idealism: Understanding the Core Conflict
According to Marx’s theory, the basic problem of philosophy is the conflict between materialism and idealism. A simplified analysis allows us to separate objects and phenomena into material and ideal. For materialists, matter is primary, and awareness is a product of its complex development. Thus, reality can be explained in terms of matter in motion. Materialism asserts that the natural world can be explained without recourse to God or the Absolute, thus defending atheism. It believes that the

Max Weber’s Bureaucracy Model and Decision-Making
Weber’s Model of Bureaucracy
Weber’s model does not introduce formal variables of behavior or consider the human dimension in its framework. The bureaucratic model, according to Weber, is more efficient due to its accuracy, stability, discipline, and functionality. It facilitates control over complex organizations. Organizations require rules that must be enforced for effective functioning. Power is the ability to give orders, and legitimacy is the level of acceptance of those orders. These two concepts

Rhyniophyta
- The most primitive vascular plants.
- Extinct, grew in shallow waters in the Paleozoic era.
- They did not have true roots, but a rhizome – an underground stem (podzemok) with rhizoids (pakorienky).
- The stem was photosynthetic, lacking leaves.
- It branched into telomes (telómy).
- Isomorphic metagenesis: sporophyte and gametophyte looked alike.
Clubmosses
- Botanists first thought they resembled moss, which is why “moss” is in the name. The “club” part of the name comes from the club-like shape
