Fascism originated in Italy after World War I and later spread to other countries of Europe. There are three key characteristics:

Authoritarianism

This is the supremacy of the state, which means the state comes before individual rights. Propaganda was used to gain people's loyalty.

Ultra-Nationalism, Imperialism, and Militarism

This was an aggressive foreign policy of territorial expansions that sought to provide the state with more living space. It had a lot of racism and xenophobia because the nation was defined by race.

Economic Control

Capitalism is allowed, but the main goal is to achieve national self-sufficiency through extreme protectionism. The state establishes corporations of business owners and workers, cooperation is encouraged, and... Continue reading "The Origins and Characteristics of Fascism in Europe" »

Programming Fundamentals

What is a Constant?

A constant is a data value that remains unchanged during the execution of a program.

Three Programming Constructs

The three fundamental programming constructs are: selection, iteration, and sequence.

Logical Operators

One example of a logical operator is AND.

• Operator: and
• Description: Logical AND: True if both operands are true.
• Syntax: x and y

Functions vs. Procedures

Difference: A function is typically used to calculate a value from a given input, while a procedure is a set of commands executed in a specific order.

Similarity: Functions must return a value, but in stored procedures, it is optional. Procedures can return zero or multiple values. Functions usually have only input parameters, whereas procedures... Continue reading "Programming Concepts: Constants, Constructs, and Operators" »

The Impact of Reading vs. Television on the Mind

Some people subscribe to the belief that reading helps enhance language skills and creativity, whereas watching television does very little for these abilities. Personally, I support this opinion for several reasons, which will be detailed in this essay.

How Books Stimulate the Imagination

As we all know, books use text to convey ideas, and quite often there are no images or illustrations to picture the scenes described. Therefore, we must use our own imagination while reading. For example, when reading a fantasy novel containing mythical creatures, one typically visualizes the appearance of those characters in their mind while following the plot. In contrast, movie heroes on a TV screen are usually... Continue reading "Why Reading Beats Television for Language Learning" »

Nowadays, online learning is becoming increasingly prevalent. Many traditional universities have started to share their courses online, often for free.

Human Nutrition and Body Systems

The digestive, respiratory, excretory, and circulatory systems all play a role in nutrition.

• Digestive system: Introduces foods into the body, and prepares and transforms it to enable its use by cells.
• Respiratory system: Obtains the oxygen cells need and eliminates carbon dioxide produced during cell metabolism.
• Circulatory system: Transports nutrients and oxygen to cells and releases waste substances.
• Excretory system: Releases waste substances outside the organism.

The Digestive System: Function and Structure

The digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair. It is made up of the gastrointestinal (GI) tract and the accessory glands:... Continue reading "Human Digestive System: Organs, Functions, and Processes" »

The Pancreas

Long, greyish-white organ behind and underneath the stomach. Functions: Produces hormones (insulin & glucagon) that regulate the amount of glucose in the bloodstream. Secretes pancreatic juice which contains digestive enzymes & sodium bicarbonate.

How Digestion Works

Most digestive processes take place in the small intestine. Digestion produces nutrients that cells need:

• Monosaccharides (simple sugars): obtained from complex carbohydrates.
• Glycerol & fatty acids: obtained from fats.
• Amino acids: obtained from proteins.

Nutrient Absorption

Nutrients pass from the small intestine into the bloodstream through absorption and then are delivered to cells by the blood. The inside wall of the small intestine is covered in folds that... Continue reading "Understanding the Pancreas and Respiratory System" »

What was the social structure of cities? As during all the Middle Ages, there were big differences among the population.

The Upper Classes

The upper classes were formed by two groups.

• The upper nobility continued having their privileges, and some moved to the cities and lived in palaces.
• A new social class emerged: the wealthy bourgeoisie. These were the rich merchants, bankers and leaders of the important guilds. This group normally formed the city government.

The Lower Classes

The lower classes were formed by the rest of the population.

• The commoners formed the majority. There were small craftsmen, merchants and servants. They lived modestly.
• The lower nobility also belonged to this group. As they didn't work and didn't possess any land, they were
