Economics

Definition

Derived from the Greek word ‘oikonomos,’ meaning “one who manages a household,” economics studies how societies allocate scarce resources to satisfy unlimited wants and needs.

Core Principles

1. Trade-offs: Acquiring something necessitates forgoing something else (e.g., watching TV versus studying).
2. Opportunity Cost: The cost of something is the value of the next best alternative forgone.
3. Marginal Thinking: Rational individuals make decisions by comparing the additional benefits and costs of an action.
4. Incentives: People's behavior is influenced by incentives, such as price changes (e.g., lower prices may increase consumption).
5. Benefits of Trade: Specialization and trade allow individuals and nations to achieve higher levels

Constitution of 1956

Introduction

Pakistan came into being in 1947 after many sacrifices. After the independence of Pakistan, it was governed by the Government of India Act 1935. The constitutional history of Pakistan is quite unfortunate. However, the first Constituent Assembly introduced the Constitution of 1956 after long debates. The Constitution of 1956 was enforced on 23 March 1956. But unfortunately, it was abrogated after two years.

Salient Features of the Constitution of 1956

Following are the salient features of the Constitution of 1956:

The Rise of Plastic Surgery Among Teenagers

The prevalence of plastic surgery has significantly increased among teenagers. Nowadays, this type of surgery is sought by countless individuals aiming to fulfill their desired physical appearance.

Personally, I believe that you cannot expect plastic surgery to solve all personal problems. Plastic surgery will not make you a fundamentally different person.

Psychological Risks and Addiction

Moreover, surgery can be addictive. The compulsion to change one’s body is often a symptom of a deeper mental instability, especially because as time changes, so do the standards of beauty.

Key psychological factors include:

Heat vs. Enthalpy

Enthalpy is a property of a system, sometimes termed "heat content." It represents the system's internal energy (U) plus the product of pressure and volume (pV).

Heat is energy in transit, transferred between systems. Enthalpy (H) is a state function defining the system's state.

Hess's Law and Enthalpy

Hess's law states that the total enthalpy change for a multi-step reaction equals the sum of enthalpy changes for each individual step. This principle, grounded in the conservation of energy, allows for calculating ΔH even when direct measurement is impossible. It enables the determination of standard enthalpies of formation, useful for designing complex syntheses.

Enthalpy and Reaction Types

Enthalpy determines whether a reaction... Continue reading "Heat vs. Enthalpy, Hess's Law, Reaction Types, and Chemical Properties" »

Regressive Tax

A regressive tax is a tax that takes a larger percentage of income from low-income earners than from high-income earners. It is the opposite of a progressive tax, which takes a larger percentage from high-income earners. A regressive tax is applied uniformly to all situations, regardless of who is paying.

Regressive Tax vs. Progressive Tax

A progressive tax is a tax whose rate increases as the payer's income increases. The higher the income, the higher the proportion of their income is taxable. A regressive tax is the opposite. Its rate increases as the payer's income decreases. The progressive tax affects high-income earners, while the regressive tax affects the low-income class.
