The Catholic Monarchs established a dynastic union, developing a centralized government and an expansionist nature in both interior and exterior politics. They finalized the conquest of Granada in 1492 and supported the project of Christopher Columbus. During the last years of Henry IV, the peninsula was characterized by political instability because of the change of succession to his sister, Isabella (Pact of the Bulls of Guisando, 1468). However, this change was met by the marriage of Ferdinand and Isabella. Subsequently, Henry named his daughter, Joanna la Beltraneja (considered illegitimate by a large part of the nobility), as heiress after the Capitulation of Cervera. This caused a civil war...

The Dictatorship of Franco and His Personality

The end of the war forced Franco to better define the characteristics of his political regime. At the same time, he was the head of state, the Army, and the Falange, the only legal political party. For the regime's policy, Franco converged all anti-democratic groups into a new party: the Traditionalist Falange of the JONS.

Legislative power was reserved for the Parliament (Cortes), which was in charge of proposing and voting on laws, though Franco retained the power to veto them.

Fundamental Qualities of Sound

1. Intensity

Intensity refers to the amount of acoustic energy a sound contains, determining whether it is perceived as loud or soft. It is dictated by power and amplitude. For humans to perceive a sound, it must exceed the threshold of hearing (0 dB) without reaching the threshold of pain (140 dB). This quality is measured using a sound level meter, with results expressed in decibels (dB), named in honor of Alexander Graham Bell.

2. Pitch

Pitch indicates whether a sound is low (bass), medium, or high (treble). It is determined by the fundamental frequency of sound waves, measured in hertz (Hz):

• Low Pitch: Slow vibration = low frequency.
• High Pitch: Fast vibration = high frequency.

The human audible frequency range is... Continue reading "Understanding the Four Fundamental Qualities of Sound" »
