Introduction to Science

Study Notes

Definition of Science

Systematic study of the natural world.
Based on observation, experimentation, and evidence.

Branches of Science

Natural Sciences
- Focus on the physical world.
- Includes:
  - Physics: Study of matter, energy, and their interactions.
  - Chemistry: Study of substances and their reactions.
  - Biology: Study of living organisms and life processes.
Formal Sciences
- Concerned with abstract concepts.
- Includes:
  - Mathematics: Study of numbers, shapes, and patterns.
  - Logic: Study of reasoning and inference.
Social Sciences
- Study of human behavior and societies.
- Includes:
  - Psychology: Study of the mind and behavior.
  - Sociology: Study of social structures and relationships.
  - Economics: Study of production, distribution, and consumption.

Scientific Method

Observation: Gather information through the senses.
Question: Formulate a question based on observations.
Hypothesis: Propose a testable explanation.
Experiment: Test the hypothesis through experimentation.
Analysis: Analyze data and results.
Conclusion: Draw conclusions based on the analysis.
Communication: Share findings with the scientific community.

Key Concepts

Theory: A well-substantiated explanation of an aspect of the natural world.
Law: A statement based on repeated experimental observations that describe some aspects of the universe.
Variable: Factors that can change in an experiment; includes independent, dependent, and controlled variables.

Importance of Science

Facilitates technological advancements.
Informs public policy and health decisions.
Enhances understanding of the universe and our place in it.
Encourages critical thinking and skepticism.

Ethics in Science

Importance of integrity, transparency, and accountability.
Ethical considerations in research, particularly involving human and animal subjects.

Interdisciplinary Science

Research that combines methods and insights from different scientific disciplines.
Examples include biochemistry, environmental science, and neuroeconomics.

Definition of Science

Systematic exploration of the natural world grounded in observation and experimentation.
Relies on empirical evidence to support findings and conclusions.

Branches of Science

Natural Sciences: Explore the physical universe.
- Physics: Investigates matter, energy, and their interplay.
- Chemistry: Examines substances, their properties, and reactions.
- Biology: Studies living organisms, including their structure and processes.
Formal Sciences: Deal with abstract constructs.
- Mathematics: Analyzes numbers, shapes, and patterns.
- Logic: Focuses on reasoning and inferential processes.
Social Sciences: Analyze human behavior and societal dynamics.
- Psychology: Investigates mental processes and behaviors.
- Sociology: Looks at social structures and interpersonal relationships.
- Economics: Studies the production, distribution, and consumption of goods and services.

Scientific Method

Observation: Initial step to gather data using senses.
Question: Development of a query prompted by observations.
Hypothesis: Creation of a testable explanation for the question.
Experiment: Execution of tests to evaluate the hypothesis.
Analysis: Examination of data collected during experiments.
Conclusion: Drawing insights based on data analysis results.
Communication: Dissemination of findings to the scientific community for review.

Key Concepts

Theory: Comprehensive explanation supported by substantial evidence.
Law: Description based on consistent, observable phenomena.
Variable: Elements in experiments that can alter outcomes; includes independent, dependent, and controlled types.

Importance of Science

Drives technological progress and innovation.
Guides informed decision-making in policy and healthcare.
Deepens understanding of the universe and human existence.
Fosters critical thinking and scientific skepticism.

Ethics in Science

Vital to maintain integrity, transparency, and accountability in research.
Ethical considerations are paramount in studies involving human and animal subjects.

Interdisciplinary Science

Integrates methodologies and perspectives across scientific fields.
Examples include:
- Biochemistry: Merges biology and chemistry.
- Environmental Science: Combines natural and social sciences to address ecological issues.
- Neuroeconomics: Blends neuroscience with economic theory to explore decision making.
