The romanticism was the movement during the 19^th Century.

This period was focused in the representation of the self, the philosophy represented in society and the mind as the main source of thinking.

Poetry was the maxim exponent of Romanticism, it represented Literature. Poets considered themselves as leaders that helped to understand society. The poet taught, guided and lead the rest to the truth. They teach them how the world works.

Each poet interpreted Romanticism in his own way; the romantic elements were observed and discussed in different points of view. All of them structured their “romanticism”.

There were two generations of romantic poets. The first generation composed by W. Wordsworth and Coleridge (which is the main interest in... Continue reading "The Romanticism Movement: Poetry, Language, and Society" »

Angular Momentum Conservation

The law of conservation of angular momentum states that when no external torque acts on an object, its angular momentum remains constant.

Inverse Square Law

The inverse-square law dictates that a physical quantity's intensity is inversely proportional to the square of the distance from its source.

Energy Conservation

The law of conservation of energy states that energy cannot be created or destroyed, only transformed or transferred.

Momentum Conservation

In an isolated system, the total momentum of two objects before a collision equals their total momentum after the collision.

Energy Degradation

The first law of thermodynamics asserts that the universe's total energy is constant. The second law states that this energy's... Continue reading "Fundamental Physics Laws: Momentum, Energy, and Motion" »

mww27-narrative texnique:

Verbal economy and precision supplemented with a psychology of impersonality - uses a classical style to redeem the fragmentation, loss of value, and chaos from the war. He uses writing to produce clarity, simplicity, and strength of statement and expression, learned from his journalistic practice.

• Clean and hard prose, with simple declarative sentences built on nouns without adverbial or descriptive excess.
• Mostly coordination, rarely subordination.
• Style emphasized dialogue and vivid description.
• Eyipsis, stripping away any excess.

TWL22

The whole point of the poem is to show the meaninglessness of modern culture.

• This poem shares many characteristics with the cantos.
• It's not an imagist poem because it has 5 sections.

Simple Microscope

A simple microscope, commonly used by watch repairers, allows for the observation of minute details by magnifying an object placed within its focal length. The convex lens of the microscope produces an erect image on the same side of the lens as the object. By adjusting the distance between the object and the lens, the image can be obtained at the distance of distinct vision, enabling clear observation without straining the eyes.

Dispersion of Light

The phenomenon of splitting light into its component colors is known as dispersion of light. The band of colored components of a light beam is called a spectrum. The different colors of light in the spectrum of white light are violet, indigo, blue, green, yellow, orange, and red.

Petroleum Reservoir Classification

Petroleum reservoirs are broadly classified as oil or gas reservoirs. These classifications are further subdivided depending on:

• The composition of the reservoir hydrocarbon mixture
• Initial reservoir pressure and temperature
• Pressure and temperature of the surface production

Key Phase Behavior Definitions

1. Key Terms in Kinematics

• Motion: Change in position of an object over time.
• Position (x): The location of an object in space, often relative to a reference point.
• Displacement (Δx): Change in position, taking into account direction.
• Speed (v): The rate of change of distance with respect to time (scalar quantity).
• Velocity (v): The rate of change of displacement with respect to time (vector quantity).
• Acceleration (a): The rate of change of velocity with respect to time.
• Deceleration: Negative acceleration (slowing down).

2. Fundamental Physics Equations

• Average Speed (v_avg): v_avg = Δx / Δt (where Δt is the time interval).
• Average Velocity (v_avg): v_avg = Δx / Δt (with direction).
• Instantaneous Velocity (v): v = dx/dt (the derivative of displacement

Electrical Charge and Magnetic Field

Electrical charge is a property of matter related to the proportion of protons and electrons in its atoms. Positive electrical charge: this is produced when atoms lose some of their electrons. Negative electrical charge: this is produced when atoms gain some of their electrons. A magnet forms around itself a magnetic field, which is the area in space where its force can be felt.

Energy: Definitions and Internal Energy

Energy is the capacity bodies have to produce changes in themselves and other bodies. Electrical energy is produced by the movement of charges in and through a conductor. Electromagnetic energy is transported by electrical and magnetic waves. Chemical energy is produced during chemical processes....

Mechanisms of the Vestibular System

Vestibular System Sensitivity to Acceleration: Mechanism

The vestibular system is sensitive to acceleration (linear or rotational) through the following mechanism:

• Semicircular Canals: There are three semi-circular canals, rotated 90 degrees relative to each other.
• Each canal is sensitive to acceleration in a different plane.
• The canals are filled with fluid (endolymph), which lags behind head movement, stimulating sensory hair cells.

Detecting Head Orientation (Tilt) via the Vestibular System

If the vestibular system is sensitive to acceleration, it can also detect the orientation (tilt) of the head because of its sensitivity to gravity. The otolith organs (utricle and saccule) contain dense structures (otoconia)... Continue reading "Mechanisms of Sensory Perception: Vestibular and Auditory Systems" »
