Science - attempt to discover patterns in nature and apply that knowledge to predict how those patterns will work in future scenarios.
There are many specific branches of science that deal with one ad hoc issue, EG biological science, environmental science, etc.
Scientific data - facts obtained through repeated observations and measurements.
This type of data can be about almost anything, as long as it is collected in a methodic, precise way.
Scientific hypotheses - an attempt at explaining something that scientists have observed in nature.
Hypotheses will undergo rigorous testing to see if they are or aren't true, they will be constantly revised until an accurate statement can be agreed upon.
Scientific theory - a hypothesis that has been repeatedly tested and verified.
While a theory has been heavily tested, and mostly agreed upon, they are still subject to change, and not necessarily correct.
Scientific law - a description of a pattern that is found happening in nature over and over again.
Though repeatedly observed and agreed upon, laws can be wrong, and are subject to change if any different observations are made in the future.
Scientific methods - The techniques scientists use to collect and gather data in an accurate way so as to test hypotheses, theories, and laws.
The general method is this, observe something, ask a question about it, attempt to answer the question based on what you already know, test to see if you're correct, revise hypothesis as necessary.
Inductive reasoning - Reasoning that because what you observed happened, it will happen again under different circumstances.
This sort of reasoning can never be one-hundred percent correct, it can at best have a strong probability of being right.
Deductive reasoning - Reasoning that applies general rules to specific situations.
This sort of reasoning, if the premises are true, will always be accurate.
Frontier science - Science based off of new findings that have not undergone rigid testing yet.
This is the sort of science that is usually on the news for still being controversial.
Consensus science - Science that has been accurately tested time and time again, and is universally agreed upon.
Very reliable science that most experts will agree upon, rarely newsmaking due to its neutral level.
System - A set of mechanisms that interact in a predictable fashion and can be isolate for individual observation.
Systems are generally made up of the following parts; inputs, flows, stores, and outputs. Each part will interact to make the next part work.
Feedback loop - When a system's output is placed back into the system as an input to change the system.
Feedback loops are in place to keep the system from leaning too far in one direction and so straining the system until it breaks.
Positive feedback loop - A feedback loop that causes the system to gain more of what was put back in.
An example of this would be investing money in stocks, you put more money in the system so you can receive more money.
Negative feedback loop - A feedback loop that causes the system to use less of what was put back in.
Reusing glass bottles is an example of this, you use the same glass bottles over and over again, so you don't need to buy more.
Synergistic interaction - interaction in which 2 parts work together to do more work than they could do in their combined individual efforts.
It's basically instead of adding 2+3 to get five, you multiply 2 and 3 to get 6, you use them together instead of individually.
