Introduction to Science and Its Branches

Study Notes

Definition and Purpose

Science is the systematic study of the structure and behavior of the physical and natural world through observation and experimentation.
Its primary purpose is to understand and explain phenomena in a repeatable and testable way.

Branches of Science

Natural Sciences
- Focus on the study of the natural world.
- Includes:
  - Physics: study of matter and energy.
  - Chemistry: study of substances and their interactions.
  - Biology: study of living organisms.
  - Earth Science: study of the Earth and its systems.
Formal Sciences
- Concerned with abstract concepts and systems.
- Includes:
  - Mathematics: study of numbers and relationships.
  - Logic: study of reasoning and arguments.
  - Computer Science: study of algorithms and data.
Social Sciences
- Focus on human behavior and societies.
- Includes:
  - Psychology: study of mind and behavior.
  - Sociology: study of social behavior and structures.
  - Economics: study of production, distribution, and consumption.

Scientific Method

A systematic approach to inquiry involving:
1. Observation: Gathering data and noticing phenomena.
2. Hypothesis: Formulating a testable explanation.
3. Experimentation: Conducting tests to validate or invalidate the hypothesis.
4. Analysis: Interpreting data and results.
5. Conclusion: Drawing conclusions based on analysis.
6. Replication: Repeating experiments to ensure reliability.

Key Concepts

Theory: A well-substantiated explanation of an aspect of the natural world, based on a body of evidence.
Law: A statement describing a consistent relationship observed in nature (e.g., laws of motion).
Variable: Any factor that can change in a controlled experiment; includes independent (manipulated) and dependent (measured) variables.

Importance of Science

Drives technological advancement and innovation.
Informs policy decisions and societal issues (e.g., climate change, healthcare).
Enhances understanding of the universe and human existence.
Promotes critical thinking and problem-solving skills.

Current Trends in Science

Interdisciplinary research (e.g., bioinformatics, environmental science).
Emphasis on sustainability and ethical considerations.
Advancements in technology (e.g., artificial intelligence, genomics).

Definition and Purpose

- Sociology: Analyzes social behavior and organization.
- Economics: Studies production, distribution, and consumption of resources.

Scientific Method

A structured approach for inquiry consisting of:
- Observation: Collecting data and recognizing phenomena.
- Hypothesis: Developing a testable explanation for observations.
- Experimentation: Performing tests to verify or refute the hypothesis.
- Analysis: Interpreting the gathered data and results.
- Conclusion: Making inferences based on the analysis performed.
- Replication: Repeating experiments to confirm findings and ensure reliability.

Key Concepts

Theory: A robust explanation of a natural phenomenon, supported by extensive evidence.
Law: A consistent relationship observed in nature, such as the laws of motion.
Variable: Any factor that can change in a controlled experiment, categorized as independent (manipulated) or dependent (measured).

Importance of Science
