I. The Aristotelianism of Aquinas
The works of Aristotle, lost to the West for centuries, gained prominence in the Middle Ages thanks to the appearance of Arab and Jewish thought. This caused a great stir in European thought, which at the time was dominated by a Platonic interpretation of the world and humanity. With the rediscovery of the full Aristotelian work and the commentaries of Averroes (Ibn Rushd, 1126-Córdoba, Morocco 1198), a philosophically connected movement known as Latin Averroism

Inflation
Inflation refers to a situation in the economy where there is a general and sustained increase in prices, measured in terms of indices.
Price stability is crucial for governments to achieve all their macroeconomic objectives, so the control of inflation has been their main priority in the past 20 years.
A few important points:
- An increase in a small number of prices does not constitute inflation. The key thing is for the increase to be measured across a wide range of items that affect the

Induction Motor Formulas
COSy = R2/R1+SN / %((R1+R2/SN)^2+(X1+X2)^2)
Apparent Power
SN = (%3) * V1L * I1L
Reactive Power
QN = SN * SENy
Active Power
PN = SN * COSy
Motor Input Power
3 * (R2/S) * IF2
If Connected in Delta
IN,F = VF / %((R1 + R2/S)2 + (X1 X2 )2)
IN,F = IN,L = (%3) * IN,F
If Connected in Star
IN,F = VF/(%3) / %((R1 + R2/S)2 + ( X1 + X2 )2)
Efficiency
REND = P2 / (P2 + Pcu,1 + Pcu,2 + PFe + Pm) * 100
Pcu,1 = 3 * R1 * I1F2
Pcu,2 = 3 * R2 * I1F2
PFe = 3 * RFe * I1F2
P1 = (%) * V1,L * I1L * COSy

Campbell’s Hero’s Journey: 5 Key Stages
Campbell’s Hero’s Journey: Five Stages
In Joseph Campbell’s book, The Hero with a Thousand Faces, the author uses stories from different cultures, religions, and myths to explore the hero’s journey. He identified a common pattern of 15 stages in stories of heroes across cultures and religions. In the classic Greek sense, a hero means a person of distinguished courage and noble character who serves as a role model for behavior. Heroes exemplify the values of a culture. Myth is from the Greek word

Understanding Gross Domestic Product (GDP) and Macroeconomic Concepts
Understanding Gross Domestic Product (GDP)
The Gross Domestic Product (GDP) represents the market value of all final goods and services produced within an economy during a specific period. It can be calculated by summing the value of all final goods and services produced, or by totaling all expenditures within the economy. GDP can be measured as the total final expenditure on the economy’s production. This expenditure is divided into consumption expenditure (C), government expenditure (G), investment

Saint Augustine of Hippo: Life and Faith
Saint Augustine (354 AD) was born in Tagaste to a pagan father and a Christian mother. He lived during the decline of the Roman Empire, a period marked by significant cultural and religious transformation. Christianity, initially a persecuted religion, was gaining acceptance. In 313 AD, it was officially recognized, and by 380 AD, it became the state religion.
This shift led to a blending of two distinct traditions: Greek culture, the initial foundation of

Cost-Volume-Profit Analysis
Cost-volume-profit (CVP) analysis is used to determine how changes in costs and volume affect operating income and net income.
Assumptions of CVP Analysis
- Sales price per unit is constant.
- Variable costs per unit are constant.
- Total fixed costs are constant.
- Everything produced is sold.
- Costs are only affected because activity changes.
- If a company sells more than one product, they are sold in the same mix.
- CVP analysis requires costs (manufacturing, selling, and admin) be identified
