Study Notes
Introduction to Science
- Science is a systematic and logical approach to understanding the natural world.
- It uses observation, experimentation, and data analysis to develop explanations and models of how the natural world works.
- Science encompasses various disciplines, each with its own methods and focus areas.
- Key characteristics of science include:
- Empiricism: Reliant on observable evidence.
- Objectivity: Seeking unbiased interpretations.
- Testability: Hypotheses must be able to be tested.
- Repeatability: Experiments should be reproducible by others.
- Falsifiability: Hypotheses can be proven wrong with evidence.
Branches of Science
- Natural sciences study the natural world, both living and non-living.
- Physics: Focuses on matter, energy, motion, and forces.
- Chemistry: Studies the composition, structure, properties, and reactions of matter.
- Biology: Investigates the structure, function, growth, and evolution of living organisms.
- Earth science: Explores the Earth's structure, processes, and history.
- Social sciences study human society and behavior.
- Psychology: Investigates the mind and behavior of individuals.
- Sociology: Studies the development and functioning of human society.
- Economics: Examines production, distribution, and consumption of goods and services.
- Anthropology: Explores the origins, development, and diversity of human cultures.
- Formal sciences investigate abstract concepts.
- Mathematics: Studies numbers, quantities, shapes, and patterns.
- Logic: Examines arguments and reasoning.
- Computer Science: Studies computation and information processing.
The Scientific Method
- A systematic approach used to answer scientific questions.
- Steps involved:
- Observation: Recognizing a phenomenon.
- Question: Formulating a question about the observation.
- Hypothesis: Proposing a testable explanation for the phenomenon.
- Prediction: Formulating specific predictions based on the hypothesis.
- Experimentation: Designing and conducting an experiment to test the hypothesis.
- Data Analysis: Interpreting the results of the experiment.
- Conclusion: Determining whether the hypothesis is supported or refuted.
- Communication: Sharing the results with the scientific community.
Scientific Reasoning and the Nature of Evidence
- Scientific explanations are based on evidence, not belief.
- Scientific theories are explanations of natural phenomena that are supported by a large body of evidence. Theories are subject to change as new evidence emerges.
- Laws are concise statements about the relationships between variables in nature. They describe what happens, not why.
- Models are simplified representations of complex objects, systems, or phenomena.
- Crucial characteristics of scientific evidence:
- Empirical: Based on observation and experience.
- Reputable: Collected and analyzed following sound scientific methods.
- Consistent: Reproducible in various situations by various researchers.
Scientific Ethics and Practices
- Scientists adhere to ethical principles, especially honesty, integrity and avoiding bias.
- Data must be accurate, reliable, and documented.
- Experiments must be conducted responsibly and ethically.
- Scientific misconduct, including fabrication, falsification, and plagiarism, is unacceptable.
- Peer review process ensures scientific quality and honesty among scientists.
- Appropriate safety measures must be taken in all scientific endeavors, especially laboratory work.
Limitations of Science
- Scientific knowledge is constantly evolving.
- Science cannot answer all questions.
- Some phenomena may be beyond the scope of scientific inquiry.
- Science relies on measurable and observable phenomena, meaning not all aspects of reality can be studied.
- Subjectivity and human biases can influence research at different stages.
- Defining "truth" in science must consider the complexity of the scientific process and the potential for error.
- Science can only provide insights about the material world; it may not address fundamental questions concerning existence and meaning.
