Introduction to the Branches of Science

Study Notes

Definition of Science

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

Branches of Science

Natural Sciences
- Study of natural phenomena.
- Subdivisions:
  - Physics (study of matter and energy)
  - Chemistry (study of substances and their interactions)
  - Biology (study of living organisms)
Formal Sciences
- Study of abstract concepts.
- Includes:
  - Mathematics (study of numbers and shapes)
  - Logic (study of reasoning)
  - Computer Science (study of computation and information)
Social Sciences
- Study of societies and human behavior.
- Includes:
  - Psychology (study of the mind and behavior)
  - Sociology (study of social behavior and institutions)
  - Economics (study of production, distribution, and consumption of goods and services)
Applied Sciences
- Use of scientific knowledge for practical purposes.
- Includes:
  - Engineering (application of science for design and construction)
  - Medicine (application of biology and chemistry for health care)

Scientific Method

Observation: Gathering data through senses.
Question: Formulating a question based on observations.
Hypothesis: Proposing a testable explanation.
Experiment: Testing the hypothesis through controlled experiments.
Analysis: Evaluating data and results from experiments.
Conclusion: Drawing conclusions based on analysis.
Communication: Sharing results with the scientific community.

Characteristics of Scientific Inquiry

Empirical: Based on observations and experiments.
Repeatable: Experiments can be repeated with the same results.
Falsifiable: Hypotheses can be proven false.
Objective: Minimizes biases and relies on facts.

Importance of Science

Advances technology and medicine.
Informs public policy and environmental conservation.
Enhances understanding of the universe and our place in it.
Promotes critical thinking and problem-solving skills.

Scientific Method

Observation: Involves collecting data via the senses.
Question: Formulating inquiries stemming from observations.
Hypothesis: Proposing a testable explanation for the observations.
Experiment: Conducting controlled tests to evaluate the hypothesis.
Analysis: Reviewing data and results to assess the hypothesis.
Conclusion: Deriving conclusions based on data analysis.
Communication: Sharing findings with the scientific community for peer review.

Characteristics of Scientific Inquiry

Empirical: Relies on observations and experiments for validation.
Repeatable: Research methods can be replicated to yield the same results.
Falsifiable: Hypotheses must be able to be proven false through evidence.
Objective: Aims to minimize bias and relies solely on facts.

Importance of Science

Drives advancements in technology and medicine.
Informs public policy decisions and promotes environmental conservation.
Enhances comprehension of the universe and human existence.
Encourages critical thinking, analytical reasoning, and problem-solving capabilities.
