Introduction to Science

Definition of Science

• Systematic enterprise that builds and organizes knowledge.
• Focuses on understanding the natural world through observation and experimentation.

Key Characteristics

• Empirical: Based on observation and experimentation.
• Testable: Hypotheses can be tested and validated or falsified.
• Replicable: Experiments can be repeated to verify results.
• Falsifiable: Scientific claims must be able to be proven false.

Branches of Science

1. Natural Sciences: Study of the natural world.
   • Examples: Biology, Chemistry, Physics, Earth Science.
2. Social Sciences: Study of human behavior and societies.
   • Examples: Psychology, Sociology, Economics, Anthropology.
3. Formal Sciences: Study of abstract concepts.
   • Examples: Mathematics, Logic, Computer Science.

Scientific Method

1. Observation: Gathering data and noticing phenomena.
2. Question: Formulating a question based on observations.
3. Hypothesis: Proposing a testable explanation.
4. Experimentation: Conducting experiments to test the hypothesis.
5. Analysis: Evaluating data and results from the experiments.
6. Conclusion: Drawing conclusions based on the analysis.
7. Communication: Sharing findings with the scientific community.

Importance of Science

• Advances human knowledge and understanding.
• Drives technological innovation and development.
• Informs policy and decision-making.
• Addresses societal challenges and global issues (e.g., climate change, health).

Major Scientific Theories

• Theory of Evolution: Explanation of biological diversity through natural selection.
• Germ Theory: Understanding that diseases are caused by microorganisms.
• Theory of Relativity: Concepts of time, space, and gravity introduced by Einstein.
• Quantum Theory: Describes the behavior of matter and energy at atomic and subatomic levels.

Ethics in Science

• Importance of integrity and honesty in research.
• Ethical considerations in experimentation, particularly with human and animal subjects.
• Responsibility to communicate results accurately and transparently.

Current Trends in Science

• Interdisciplinary research combining multiple fields.
• Increasing role of technology and data science in research.
• Focus on sustainability and environmental issues.
• Advancements in biotechnology and health sciences.

Definition of Science

• Systematic process for building and organizing knowledge.
• Aims to understand the natural world through observation and experimentation.

Key Characteristics

• Empirical: Relies on observation and experimentation for data collection.
• Testable: Allows for hypotheses to be validated or disproven through experiments.
• Replicable: Ensures outcomes can be repeated by others to confirm findings.
• Falsifiable: Scientific claims must have the potential to be proven false.

Branches of Science
