Introduction to Science

Definition of Science

• Systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Branches of Science

1. Natural Sciences

   • Study of natural phenomena.
   • Key fields: Physics, Chemistry, Biology, Earth Science.

2. Formal Sciences

   • Study of abstract concepts.
   • Key fields: Mathematics, Logic, Statistics, Computer Science.

3. Social Sciences

   • Study of human behavior and societies.
   • Key fields: Psychology, Sociology, Anthropology, Economics.

Scientific Method

• A systematic approach to research and experimentation.

1. Observation: Gather information through senses.
2. Question: Formulate a question based on observations.
3. Hypothesis: Propose a testable explanation.
4. Experimentation: Conduct tests to validate or invalidate the hypothesis.
5. Analysis: Interpret data and results.
6. Conclusion: Draw conclusions and report findings.
7. Replication: Repeat experiments to confirm results.

Key Concepts

• Theory: A well-substantiated explanation of an aspect of the natural world.
• Law: A statement based on repeated experimental observations that describes an aspect of the world.
• Variable: Any factor that can change in an experiment (Independent, Dependent, Controlled variables).

Importance of Science

• Advances understanding of the universe and life.
• Drives technological innovation and societal development.
• Informs policy decisions and addresses global challenges (e.g., climate change, health crises).

Ethics in Science

• Responsibility to conduct research honestly and ethically.
• Importance of peer review and reproducibility.
• Consideration of the impact of scientific research on society and the environment.

Current Trends in Science

• Data Science: Use of statistical and computational techniques to analyze large datasets.
• Sustainability Science: Focus on the interactions between human systems and natural systems.

Notable Scientists

• Isaac Newton: Laws of motion and universal gravitation.
• Albert Einstein: Theory of relativity.
• Marie Curie: Research on radioactivity.

Scientific Literacy

• Understanding basic scientific concepts and processes.
• Ability to critically evaluate scientific information and claims.
• Importance in making informed decisions in everyday life.
