Introduction to Science

Science

• Science is a systematic enterprise building and organizing knowledge in the form of testable explanations and predictions about the universe.
• It involves observation, experimentation, and the formulation of hypotheses and theories to explain natural phenomena.
• Key branches of science include physics, chemistry, biology, and earth science.
• Physics studies matter, energy, and their interactions.
• Chemistry focuses on the composition, structure, properties, and reactions of matter.
• Biology explores living organisms and their interactions with each other and their environments.
• Earth science investigates the Earth's physical structure, processes, and history.
• The scientific method involves formulating a hypothesis, designing and conducting experiments, analyzing data, and drawing conclusions.
• Scientific laws describe observed patterns in nature, while scientific theories explain those patterns and provide a deeper understanding of underlying mechanisms.

Mathematics

• Mathematics is a formal system of logic and reasoning used to quantify and model the world around us.
• It involves the study of numbers, shapes, quantities, and patterns.
• Key areas of mathematics include arithmetic, algebra, geometry, calculus, and statistics.
• Arithmetic deals with basic operations on numbers.
• Algebra involves using symbols and variables to represent quantities and relationships.
• Geometry studies shapes and their properties and relationships.
• Calculus deals with rates of change and accumulation.
• Statistics deals with collecting, organizing, analyzing, and interpreting data.
• Mathematical concepts are widely used in other fields such as science, engineering, and computer science.
• Mathematical models and equations are used to solve problems, make predictions, and understand phenomena.

General Knowledge (GK)

• General Knowledge (GK) encompasses a wide range of information about current events, history, geography, culture, and other subjects.
• GK includes facts, figures, and details about various aspects of the world.
• GK is important for developing critical thinking, problem-solving skills, and communication abilities.
• GK enables individuals to understand and relate to the world around them.
• GK often involves understanding historical events, prominent figures, and significant developments related to various cultures.
• GK includes an awareness of geographical locations, landmarks, and political systems.
• Remaining updated on current events and social issues is an important component of GK.
• GK builds on a framework of understanding.
• Sources of GK include news articles, books, documentaries, discussions, and more.
