Study Notes

Science and Understanding

Science seeks to explain the natural world using evidence gathered from our senses and their extensions
Scientific ideas are developed through logical reasoning, drawing conclusions based on observable facts
Scientific claims are tested through repeated experiments and observations, and are either rejected, modified, or accepted based on the evidence
Science is always evolving and conclusions are always tentative, open to scrutiny and modification as new evidence appears
Science is not a democracy – ideas are accepted or rejected solely based on evidence, not on popularity
Science is non-dogmatic – explanations and conclusions are only accepted if they are well-founded and continue to withstand scrutiny
Science cannot make moral or aesthetic decisions – it can describe relationships but not assert personal preferences, while scientists, like everyone, still make personal judgments outside of science
Science is not always linear – some theories once accepted may later be found to be inaccurate or incomplete, as our understanding progresses over time
Science corrects itself – errors are identified and rectified over time with advancements in technology, perspectives, and understanding

Technology

Technology is the application of scientific knowledge for practical purposes – usually for industry and improving the human condition
Technology encompasses techniques, skills, methods, and processes used to produce goods, services, or achieve objectives
Basic tools, the control of fire, the wheel, the printing press, the telephone, and the Internet are examples of technology that have shaped human society
Technology has advanced economies, enabled global communication, and increased leisure, but also created pollution and depleted resources
Innovations often impact societal values and raise ethical questions, like efficiency and bioethics

Non-Science and Pseudoscience

Non-science refers to areas of knowledge that do not adhere to scientific criteria like consistency, observability, testability, and predictability
Non-science encompasses areas of knowledge that are logical, but not within the realm of science, such as belief systems, philosophy, opinions, aesthetics, or ethics
Pseudoscience presents itself as scientific, but lacks valid scientific methodology, supporting evidence, or testability
It often utilizes vague, exaggerated, or unprovable claims, relies on confirmation bias rather than refutation, and lacks openness to rational development of theories

Scientific Method and Inquiry

Across scientific disciplines, evidence, hypotheses, theories, and logic are fundamental
Scientists may investigate different phenomena and employ diverse approaches, but share an understanding of what constitutes a valid scientific investigation
Scientific inquiry is driven by curiosity and acceptance of explanations based on evidence and proof
The scientific method is a structured approach for proving hypotheses, consisting of:
- Stating the problem
- Forming a hypothesis
- Testing the hypothesis
- Recording and analyzing data
- Forming a conclusion
- Replicating the work
When a hypothesis is repeatedly tested and confirmed, and is unlikely to be disproven, it may become a theory
Theories are time-tested concepts that offer reliable and useful predictions about the natural world
Common sense and logic can also explain events or phenomena, not everything requires an experiment
