Understanding Communication: Types and Levels

Communication is a process in which an individual interacts through verbal and nonverbal language, where information is exchanged.

  • Assertive: We speak of belief when we are sure of something but do not have enough evidence to prove it.

Knowledge is a belief that we are safe and we can prove. Rationally justifying something is characteristic

Karl Marx: Key Concepts and Theories

Karl Marx: A Summary of Key Ideas

1. Political Economy and Historical Materialism

Marx argued that the anatomy of civil society is found in political economy. Through the lens of historical materialism, he explained that the economic infrastructure is the key to understanding a given society and the changes it experiences throughout history. A society’s economic infrastructure (the functioning of its economy) shapes its superstructure, which includes legal, political, and ideological elements (laws,

Electronic Textuality: Semiotics, Cyborgs, and Literature

Electronic Textuality and Its Unique Characteristics

Since the advent of the information society, the modalities of reading and writing have fundamentally changed. The question of reading and writing, a crucial element of European self-consciousness since the development of vocalized alphabetical writing in the eighth century, has re-emerged, bringing with it new questions, paradoxes, and opportunities.

Three Dimensions of Electronic Textuality

When considering electronic textuality, it’s useful to

Human Interaction, Nervous and Endocrine Systems

1. The Interaction Process

This function includes a series of processes whose objectives are:

  • To adapt the body to changing conditions, in the internal as well as external environment.
  • To connect and coordinate the different parts of our body so that they work together.

1.1. Homeostasis

Homeostasis processes maintain the body’s stability when there are changes in the internal environment.

Homeostasis processes work like a feedback device. This means that when a variation is detected in a particular element,

Relativity, Quantum Theory, and Uncertainty

Relativity: Concepts and Postulates

The study of relativity establishes that time and space are relative. This means that they cannot be handled with an absolute reference system because the measurement of space and time will depend on the observer.

In 1905, Albert Einstein published the Special Theory of Relativity, based on two postulates:

Postulate 1

The laws of physics are the same for all referential frames that move at a constant speed compared to others.

Example: If you are sitting still on a

Calyces and Renal Pelvis

Calyces: These are smaller, cup-shaped structures where urine collection begins. Minor calyces surround each renal papilla (the tip of a renal pyramid). They are small membranous ducts that open into the major calyces.

Major Calyces: Typically, there are three major calyces: superior, middle,
