World War I: Key Phases and Turning Points 1914-1918
The Phases of World War I
The Schlieffen Plan and the Outbreak of War
The German General Staff had a war plan, called the “Schlieffen Plan,” with which they sought a quick victory based on the speed of movement, avoiding the danger of a war on two fronts, which would be catastrophic for a central power like Germany. It was based on the idea that the Russians would take longer to mobilize, as their level of technological development was much lower. The plan was launched on the French front through

Diodes: An Introduction
A diode (Greek: two roads) is a semiconductor device that allows the passage of electric current in one direction, with characteristics similar to a switch. In simple terms, the characteristic of a diode (IV) consists of two regions: below a certain potential difference, it behaves like an open circuit (no leads), and above it as a closed circuit with a very small electrical resistance.
Because of this behavior, diodes are often referred to as rectifiers. They are devices that

Literature of Exile
After the War of 36, many Galician writers, artists, and intellectuals went into exile to escape Franco’s repression and strengthen Galicianism.
In poetry, the theme was addressed through the complaint and relief of social drama, Galician patriotism, and reflection on the state of exile.
Authors in Exile:
- Luis Seoane: A Galeguista party member, exiled to Argentina. Notable works include Fardel exile, Fog Sant-Iago, and Ascicatrices Valume. His poetry has a realistic style with social
Kant and Weber: Ethics in Politics and Morality
Kant: Morality, Freedom, and Reason
The Interplay of Morality and Freedom
Kant argues that the existence of morality is intrinsically linked to freedom. To justify the demands of morality, one must demonstrate the reality of freedom. Kant distinguishes between two uses of reason, with the practical use being the focus of his works, *Groundwork of the Metaphysics of Morals* and *Critique of Practical Reason*. Reason draws a clear line between duty and desire, morality and self-interest. Moral standards,

How Do Stars Release Energy?
The core of a star is an intense environment. The pressures are enormous, and the temperatures can be greater than 15 million Kelvin. These are the kind of conditions you need for nuclear fusion to take place. Once these conditions are reached in the core of a star, nuclear fusion converts hydrogen atoms into helium atoms through a multi-stage process.
To complete this process, two hydrogen atoms are merged together to form helium. This whole reaction is exothermic, and

Native Americans & Spanish Explorers
They first arrived 30,000 years ago or before. It is believed that the first settlers came from Asia and crossed the land bridge that united the 2 continents (The Bering Strait – between Russia & Alaska).
Native American Cultural Regions
In the mid 1500s, 10 million Indians lived in North America with several hundred languages and varying social structures.
- Maize Regions – in Eastern half (NE & SE). Depended on hunting, fishing, farming, and gathering.
American and French Revolutions: Causes and Impacts
The American Revolution: Causes and Consequences
The American Revolution was a conflict between the settlers of New England and Great Britain. The source of the problem was economic. The colonies had developed their own economic system and began to see the metropolis as a barrier to their development. The colonies were ruled by the colonial pact, which granted enough freedom to the colonists, and there were some meetings where part of the taxes were collected. This ended with conflict-generating

Thomas Hobbes and the Leviathan
Thomas Hobbes, a prominent 17th-century English philosopher, is best known for his work Leviathan. This work explores his theory of absolutism. Hobbes posits that in a natural state, humans would be entirely free, with no limitations. He argues that society restricts individual freedom. In this natural state, there is no society, and therefore, no impediment to freedom. However, this natural state is governed by the law of the stronger or more intelligent. Man’s nature

The Parthenon: A Doric Temple
The Parthenon, built in the Greek Doric order, is an octastyle temple, featuring eight columns on each facade. It’s a peripteral structure, with columns surrounding the building—17 on the longer sides. The entire structure rests on a stylobate and two stereobates. The columns lack bases and have longitudinal grooves. A slight widening of the shaft towards the center creates the illusion of inward tilting. The shafts terminate in a necking, topped by a capital composed

Prime Numbers, GCD, and Congruence
Prime Numbers: Numbers > 1 with no divisors other than 1 & itself.
GCD: Largest positive integer dividing 2 numbers without a remainder.
Congruence: 2 numbers are congruent modulo N if they have the same remainder when divided by N (A ≡ B mod N).
Classical vs. Modern Cryptography
Classical Cryptography:
- Based on secrecy of the encryption algorithm.
- Key distribution was physical & therefore not as secure.
- Encryptions like the Caesar cipher were susceptible
