| ====Research Concepts / Definitions==== | ==== Science, Technology, Philosophy, Mathematics ==== |
| | |
| | | Philosophy | A systematic investigation into any phenomenon. Fundamental principle: Human reasoning and creativity. | |
| | | Science | A systematic investigation into phenomena in the natural world susceptible to physical experimentation. Fundamentally inductive. | |
| | | Technology | Tools and techniques for getting things done. Fundamental principle: Composition. | |
| | | Mathematics | A systematic study of quantity, numbers, patterns, and their relationships. Fundamentally deductive. | |

| | Theory (isl. kenning) | "A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena." [[http://dictionary.reference.com/search?q=theory|REF]] \\ A theory is a relatively big explanation, covering several phenomena, often through a single principle, or a set of simple principles. | | | Theory (isl. kenning) | "A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena."

| | Sorting out variables |Independent variables: These are factors that need to be controlled for the results to be more intelligible. Example: If we want to study the efficiency speedup seen by a new multi-cultural word processor we would want to have all or some of the cultures represented when we do the study. | | | Sorting out variables | Independent variables: These are factors that need to be controlled for the results to be more intelligible.
