Introduction to Science

Definition of Science

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

Key Features of Science

• Empirical: Based on observable and measurable evidence.
• Testable: Must be able to be tested and potentially falsified.
• Repeatable: Experiments must yield consistent results when repeated.
• Predictive: Capable of making predictions about future events or phenomena.

Scientific Method

1. Observation: Noticing and describing phenomena.
2. Question: Formulating a question based on observations.
3. Hypothesis: Proposing a tentative explanation or answer.
4. Experimentation: Testing the hypothesis through controlled experiments.
5. Analysis: Interpreting the data collected to determine if it supports the hypothesis.
6. Conclusion: Drawing conclusions based on analysis; may lead to further questions.

Branches of Science

• Natural Sciences: Study of the physical world (e.g., physics, chemistry, biology).
• Formal Sciences: Study of abstract concepts (e.g., mathematics, logic).
• Social Sciences: Study of human behavior and societies (e.g., psychology, sociology).
• Applied Sciences: Practical application of scientific knowledge (e.g., engineering, medicine).

Importance of Science

• Advances technology and medicine, improving quality of life.
• Promotes critical thinking and problem-solving skills.
• Helps to understand and address global challenges (e.g., climate change, health crises).

Ethical Considerations in Science

• Responsible conduct of research (e.g., honesty, integrity).
• Ethical treatment of human and animal subjects.
• Awareness of environmental impact and sustainability.

Notable Scientists and Contributions

• Isaac Newton: Laws of motion and universal gravitation.
• Charles Darwin: Theory of evolution by natural selection.
• Marie Curie: Research on radioactivity; first woman to win Nobel Prize.
• Albert Einstein: Theory of relativity, fundamentally changed our understanding of space and time.

Current Trends in Science

• Interdisciplinary research combining various scientific fields.
• Biotechnology and genetic engineering revolutionizing medicine.
• Artificial intelligence and machine learning in data analysis.
• Climate science focusing on sustainability solutions.

Definition of Science

• Science is a systematic process of building and organizing knowledge about the natural world through observation and experimentation.

Key Features of Science

• Scientific knowledge is based on empirical evidence, meaning it's observable and measurable.
• Scientific hypotheses and theories are testable and potentially falsifiable.
• Scientific findings are repeatable; consistent results are expected when experiments are repeated under similar conditions.
• Science aims to be predictive, forecasting future events or phenomena based on established knowledge.

Scientific Method

• The scientific method is a cyclical process starting with observation, followed by questioning, developing a hypothesis, conducting experiments, analyzing data, and drawing conclusions which may lead to further investigation.

Branches of Science

• Natural sciences study the physical world, including physics, chemistry, and biology.
• Formal sciences deal with abstract concepts like mathematics and logic.
• Social sciences investigate human behavior and societies, such as psychology and sociology.
• Applied sciences involve practical application of scientific knowledge, encompassing engineering and medicine.

Importance of Science

• Science drives advancements in technology and medicine, improving people's lives.
• It fosters critical thinking and problem-solving skills.
• Science helps us address global challenges such as climate change and health crises.

Ethical Considerations in Science

• Responsible conduct of research necessitates honesty and integrity.
• Ethical treatment of human and animal subjects is paramount.
• Scientists must be mindful of environmental impact and promote sustainability.

Notable Scientists and Contributions

• Isaac Newton formulated the laws of motion and universal gravitation.
• Charles Darwin developed the theory of evolution by natural selection.
