Unformatted text preview: Resources Geology 22/01/2008 07:02:00 The goal of science is to attempt to understand the natural world around us Based on the assumption that natural events occur in an orderly pattern Understanding those patterns allows us to provide explanations of natural phenomena and to try to predict the occurrence of such phenomena Model- an approximation, simplification, or simulation of something that is being Hypothesis- a tentative explanation or educated guess that needs further evaluation Scientific method- Problem or question Do experiments, make observations, collect data Interpret data Formulate hypothesis to explain observations/data, Make predictions Test Hypothesis (A hypothesis must always be able to be tested!!!) Revise hypothesis if necessary Scientific theory- shit that has withstood testing over time Scientific law- shit that works exactly the same wherever you are (gravity etc.) Scientific Law- a concise but general statement about how nature behaves (something that occurs over and over in the same way) Scientific Theory- a certain or nearly certain, widely accepted scientific conclusion Science is not black and white. Scientists cannot prove that their theories, laws, models are absolutely true Scientists can: 1. Disprove something 2. establish a high probability of something An important part of science is communication. Presentation and publication of new data, models, and theories is important so that they can be peer reviewed (a.k.a. hypotheses can be tested!!!) The very nature of the scientific method is that scientific theories are constantly being revised and refined. SCIENCE IS NOT ABSOLUTE!! Scientific method and Geology One important thing that distinguishes geology from most other sciences is the consideration of time Geology often involves extremely large time units which are not easy to conceptualize for most people Natural processes and material are commonly very complex and cant always be easily tested or reproduced in a laboratory setting o Ex. You cant come up with a life size simulation of an erupting volcano Systems System- any part of the universe that we wish to select for study. We define what the boundaries are. Systems are made up of components that interact with each other in some manner Models are frequently used to simulate or approximate some systems Types of Systems Isolated system Completely separated from the surrounding universe. No exchange of mass ore energy between the system and the surroundings. True isolated systems do not exist-...
