Study Notes
- Science is the study of humanity through observation, thought, experimentation, and validation.
Characteristics of Science
- Science aims to explain the natural world through evidence gathered via our senses.
- Scientific understanding relies on information from observations of nature.
- Real materials and observations are the true tests of any concept.
- Scientific ideas develop through reasoning, where inferences are logical conclusions based on observable facts.
- Science uses evidence and reasoning to reach conclusions based on data.
- Claims are tested against observations of the natural world and those that fail are rejected.
- Explanations are evaluated on evidence generated through experiments and observations.
- Scientific conclusions are reliable but tentative and subject to scrutiny and modification with new evidence.
- Scientific ideas are accepted or rejected based on evidence, not popular opinion.
- Accepted explanations and conclusions must be well-founded and continuously stand up to scrutiny.
- Science doesn't make moral or aesthetic decisions, but rather focuses on objective relationships and observations.
- Science makes moral and aesthetic judgments, but those judgements are separate from scientific fact.
- Scientific ideas can be inaccurate or incomplete and not a direct path to truth.
- Spontaneous Generation is an outdated theory where living organisms arise from nonliving objects.
- Science is self-correcting through challenging past "truths" and improved understanding from new technology.
Technology
- Defined as the "Science of Craft" which is applying scientific knowledge for practical purposes like industry and improving life.
- Greek origin: techne (art, skill) and logia (application of knowledge).
- It includes the techniques, skills, methods, and processes used in the production of goods or services.
- Technology can involve the simplest tools like controlling fire or agriculture.
- Technology now includes phones, internet, and the rise of the leisure class.
- Technology can produce unwanted by-products like pollution.
- Innovations influence societal values and ethics.
Non-Science
- Non-science lacks consistency, observability, testability, and predictability.
- Non-science includes religious beliefs, philosophy, personal opinions, aesthetics, or ethics.
Pseudoscience
- Pseudoscience presents itself as scientific, but lacks valid methodology, evidence, or testability.
- Pseudoscience is characterized by vague claims, over-reliance on confirmation, and a lack of openness to developing theories.
Scientific Method and Inquiry
- Scientific disciplines rely on evidence, hypotheses, theories, and logic.
- Scientists investigate different phenomena and have various approaches to the work.
- Scientists exchange techniques, information, and concepts.
- Valid scientific investigation consists of the following steps:
- Stating the problem
- Forming a hypothesis
- Testing the hypothesis
- Recording/analyzing data
- Forming a conclusion
- Replicating the work
- A repeatedly confirmed hypothesis can become a theory.
- A scientific theory is a time-tested concept that makes useful predictions about the natural world.
- Explanations do not always require experiments; common sense and logic can be sufficient.

Description
Science explores humanity through observation, thought, experimentation, and validation. It explains the natural world using sensory evidence. Scientific understanding relies on nature observations, tested with real materials, and developed through reasoning. Claims either pass the test against observations or are rejected.
