Lecture #2 Flashcards
(42 cards)
Define science
A process of gaining knowledge about the natural world
What is the scientific method?
The use of experiments and observations to explain something in nature
Define hypothesis
Proposed (tentative) explanation of a phenomenon that can be tested (normally based on a prediction that follows from the hypothesis)
What is a theory?
Widely accepted and tested (confirmed) explanation for a phenomena
What is a law?
Description of how behaves under certain conditions (often mathematical formula, rare in natural sciences)
What fields of study are considered natural sciences?
Physics, geology, biology, and chemistry
Who is associated with Holism?
*He also co-developed island biogeography
Wilson
What is Holism?
Emphasizes a ‘complex systems’ approach to science that focuses on a ‘top-down’ approach by studying higher organizational levels: “The whole is more than the sum of its parts”
Define emergence
Properties of groups that can’t be entirely explained by their individual components (across scales)
Who is associated with Reductionism?
“Explain all biology in terms of physics and chemistry”
Crick
What is reductionism?
Describes systems by dividing them into smaller units to understand them through their elemental properties; bottom-up approach: “the whole is simply the sum of it’s parts”
What is normative science?
Information is developed or interpreted on an assumed, usually insinuated, preference for a particular outcome or policy; applied science; produces facts and measurements
What is a descriptive science?
Studying nature for the sake of understanding how nature worlds without an a priori application; basic science
___ reasoning is common in the basic sciences; starts with the theory -> hypothesis -> observation -> confirmation
Deductive
___ reasoning is common in the applied sciences; starts with an observation -> pattern -> hypothesis -> theory
**Natural sciences
Inductive
Define deductive reasoning
Building up to a specific principle through a chain of increasingly narrow statements
Define inductive reasoning
Proves a general principle by highlighting a group of specific events, trends, or observations
Who is associated with falsification of hypothesis?
Popper
How is a single hypothesis disproved?
By confirmation of data; be able to test
Who is associated with the following key phrase: paradigms, normal science, scientific revolutions
Kuhn
What hypothesis starts with 1 theory until evidence proves otherwise?
Single hypothesis
Republic of science is associated with who?
Polanyi
What did Polanyi believe when it comes to studying science?
Multiple views of the world allowed according to the different opinions of scientists; confrontation between these views and data judged on: 1) plausibility 2) value 3) interest
The confrontation of multiple hypotheses with data as an arbitrator (scientific research program) is associated with who?
Lakatos
