Ο Χρόνος που Χάθηκε: Η Υποβάθμιση της Ποιότητας Ζωής μας
Καθημερινά γίνεται λόγος για τους γρήγορους ρυθμούς, τον ανταγωνισμό και το άγχος που χαρακτηρίζουν τη σύγχρονη εποχή. Στον βωμό των πολλών και επειγουσών επαγγελματικών υποχρεώσεων, ο άνθρωπος θυσιάζει τον προσωπικό
Mirror/lens formula: 1/f = 1/v + 1/u
Magnification: m = v/u = h_{i}/h_{o}
Power of lens: P = 1/f (f in metre)
Combination of lenses: P eq =P 1 +P 2 +***
Refractive index: n= sin x sin(i/r) = c/v
Critical angle: sin C = 1/n
Direct numerical tips:
Always use sign convention.
Convert focal length in cm to metre for power.

1- State and explain first law in thermodynamics.
The First Law of Thermodynamics is a specific application of the Law of Conservation of Energy. It establishes that energy cannot be created or destroyed, only converted from one form to another. In a thermodynamic system, it describes the relationship between heat, work, and the internal energy of the system.
1. Statement of the Law
The law states that the change in the internal energy of a closed system is equal to the amount...
famous work The Republic Plato believed that the state is a natural and moral institution created to ensure justice and harmony in society.
His central idea: “Justice in the state =everyone doing their own proper work.”
He compared the state with the human soul.
Basis of Plato’s State (Soul Analogy)
Soul Part: quality, class in state;
Reason:Wisdom,Rulers (PhilosopherKings); Spirit:Courage,Soldiers(Auxiliaries);
Appetite:Desire,Producers(Farmers,artisans)

Business ethics isn't just about "being nice"—it’s the strategic application of moral standards to the complexities of modern commerce. It’s the difference between a company that survives a scandal and one that thrives because of its reputation.
Here is a breakdown of the core pillars of Business Ethics.
## 1. Meaning and Concept
Business ethics refers to the system of moral principles and rules of conduct applied to business activities. It involves a "value-based" approach to decision-making,
The **G20/OECD Principles of Corporate Governance** are the international benchmark for policy makers, investors, and corporations. Originally issued in 1999, they were most recently updated in **2023/2024** to address modern challenges like climate change, digitalization, and the rise of institutional investors.
The principles are organized into six key chapters:
### I. Ensuring the Basis for an Effective Corporate Governance Framework The framework should promote transparent and fair markets and
