Core Principles of Modern Physics: Relativity and Quantum Theory
Frames of Reference
- Inertial frame of reference: A frame at rest or moving with constant velocity where Newton’s First Law of Motion holds true and no extra forces are required.
- Non-inertial frame of reference: A frame that is accelerating or rotating where Newton’s laws require fictitious (pseudo) forces to explain motion.
Laws of Radiation
- Wien’s displacement law: The wavelength at which a body emits maximum radiation is inversely proportional to its temperature (λmax ∝ 1/T and λmaxT = Constant)
Game Development Essentials: Pygame and Unity Systems
Pygame Game Loop Fundamentals
Definition: The Game Loop in Pygame is a continuous cycle that keeps the game running by handling input, updating logic, and rendering output.
Core Steps
- Input: Get user input.
- Update: Update the game state.
- Render: Display the results on the screen.
Key Concepts
- Runs continuously until the game ends.
- Each cycle is referred to as a frame.
Explanation and Application
The loop keeps the game active and controls the overall flow. It is used in all Pygame projects to help create

A–C
- Assimilation: Migrants are expected to adopt the dominant culture and language completely.
- Authenticity: The idea that a language has value because it is strongly connected to a specific place, culture, or community.
- Centralization: The state controls language rules, education, and communication.
- Citizenship Language Requirement: A rule that migrants must learn the official language to become citizens.
- Complementary Signs: Signs where different languages give different pieces of information that
South American Regionalism and the United Nations Structure
Specific Features of South American Regionalism
South America is highly “over-organised,” with countries belonging to multiple overlapping groups (e.g., MERCOSUR, CAN, UNASUR, CELAC, ALBA, ALADI). This creates an “alphabet soup” of acronyms with no clear hierarchy. Unlike the EU, there is no single dominant organisation—only competing projects shaped by shifting political ideologies.

1. Basic Pygame Functions
Pygame is a Python library used to create games.
Common Functions
- pygame.init(): Initializes all Pygame modules
- pygame.display.set_mode((width, height)): Creates the game window
- pygame.display.set_caption(“Title”): Sets window title
- screen.fill(color): Fills screen with a color

Secularisation and Immigration in the NZ Catholic Church
The Impact of Secularisation on the Catholic Church
Secularisation, the process by which religion loses its social and cultural significance, has significantly influenced the Catholic Church in Aotearoa New Zealand by contributing to a decline in traditional affiliation among certain demographics. The 2013 Census data illustrates this trend, showing that while nationally 55 percent of the population had a religious affiliation, this represents a decline from previous years.

Classical Trade Theories
- Mercantilism: Dominated between the 16th and 18th centuries, viewing trade as a zero-sum game. The goal was to accumulate gold and silver by promoting exports and restricting imports.
