Study Notes
Goal of Science
- Science aims to understand the natural world through systematic study.
- Scientists make assumptions including that nature is governed by natural laws and that scientific ideas can be revised.
Understanding Nature
- Nature is seen as a unified system influenced by natural laws.
- Scientific laws describe consistent behaviors under specific conditions, such as the law of gravity, articulated by Sir Isaac Newton.
- Newton’s laws of motion and gravity explained numerous natural phenomena, including the motion of falling objects and lunar orbits.
Evolution of Scientific Ideas
- Science is dynamic; it evolves and adapts through ongoing testing and revision of ideas.
- New observations can challenge existing theories, transforming them rather than invalidating them.
- Albert Einstein’s theory of relativity expanded upon Newtonian physics without discarding it, illustrating the layering of scientific understanding.
Endurance of Scientific Knowledge
- Long-lasting scientific theories, such as John Dalton’s atomic theory, remain validated after centuries of scrutiny.
- Many foundational scientific concepts are routinely tested and reaffirmed within various branches of science, including biology.
Limitation of Science
- Science relies on observable evidence and logic, excluding questions regarding the unobservable, such as supernatural phenomena.
- Example questions:
- Observable: Did life on Earth evolve over time?
- Non-observable: Was life created through a different method?
Scientific Method
- The scientific method guides scientific investigations, providing a structured approach to inquiry.
- Investigations typically begin with making observations, followed by a plan to test hypotheses.
Types of Observations
- Quantitative Observations: Involve numerical data and measurements, yielding specific results (e.g., “the girl has 85 cents”).
- Qualitative Observations: Offer descriptive, non-numeric insights, often leading to vagueness (e.g., “the girl has very little money”).
