Introduction to Science and Its Branches

Study Notes

Definition of Science

Systematic study of the natural world through observation and experimentation.
Aims to explain natural phenomena and develop theoretical models.

Branches of Science

Natural Sciences
- Physics: Study of matter, energy, and the fundamental forces of nature.
- Chemistry: Study of substances, their properties, reactions, and transformations.
- Biology: Study of living organisms and their interactions with the environment.
Formal Sciences
- Mathematics: Study of numbers, quantities, shapes, and patterns.
- Logic: Study of reasoning principles and arguments.
- Computer Science: Study of algorithms, data structures, and computational processes.
Social Sciences
- Psychology: Study of behavior and mental processes.
- Sociology: Study of society, social institutions, and social relationships.
- Economics: Study of the production, distribution, and consumption of goods and services.
Applied Sciences
- Practical application of scientific knowledge to solve real-world problems.
- Includes fields like engineering, medicine, and environmental science.

Scientific Method

Observation: Identifying a phenomenon or problem to study.
Questioning: Formulating questions based on observations.
Hypothesis Formation: Proposing explanations that can be tested.
Experimentation: Conducting experiments to test hypotheses.
Data Analysis: Analyzing data collected from experiments.
Conclusion: Drawing conclusions based on data; accepting or refuting hypotheses.
Communication: Sharing results with the scientific community.

Importance of Science

Fosters critical thinking and problem-solving skills.
Drives technological advancement and innovation.
Contributes to the understanding of health, environment, and society.
Informs public policy and decision-making through evidence-based research.

Key Concepts

Theory: A well-substantiated explanation of an aspect of the natural world.
Law: A statement that describes an observable phenomenon or a set of observations.
Experiment: A controlled method of testing a hypothesis.
Peer Review: The process of subjecting scientific work to scrutiny by others in the field before publication.
