Branches of Science and Scientific Method

Study Notes

Definition

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Branches of Science

Natural Sciences
- Focus on the natural world (e.g., physics, chemistry, biology).
Formal Sciences
- Deal with abstract concepts (e.g., mathematics, logic, statistics).
Social Sciences
- Study human behavior and societies (e.g., psychology, sociology, anthropology).
Applied Sciences
- Use scientific knowledge for practical applications (e.g., engineering, medicine).

Scientific Method

Observation
- Identifying a phenomenon or problem.
Hypothesis
- Formulating a testable statement or prediction.
Experimentation
- Conducting tests to gather data.
Analysis
- Interpreting data to determine if the hypothesis is supported.
Conclusion
- Drawing conclusions and communicating results.
Replication
- Other scientists repeat the experiment to verify results.

Types of Research

Descriptive
- Observes and describes characteristics of the subject.
Analytical
- Digs deeper into the reasons behind phenomena.
Experimental
- Involves controlled experiments to test hypotheses.

Importance of Science

Advances technology and medicine.
Informs public policy and environmental decisions.
Enhances understanding of natural phenomena.

Concepts in Science

Theory
- A well-substantiated explanation based on evidence (e.g., theory of evolution).
Law
- A statement based on repeated experimental observations (e.g., laws of thermodynamics).
Model
- A simplified representation of complex systems to help understand and predict behaviors (e.g., atomic models).

Ethical Considerations

Scientific integrity and honesty in research.
Consideration of the societal impact of scientific advancements.
Ethical treatment of research subjects (human and animal).

Current Trends

Interdisciplinary research combining multiple fields.
Emphasis on sustainability and addressing climate change.
Use of technology and big data in science (e.g., bioinformatics, AI in research).
