Introduction What is Science? o Text presents a generic view of science and how it works o It is measureable, empirical, not value judgements o Quantification o Learning about things- our attempt to understand and explain the universe and all that is in it o Understanding is gained through research o Empirical - relies on observation and experience Measureable, must be reproducible Major Areas of Science: o Physical sciences (physics, chemistry- heavy on lab work) o Biological sciences o Behavioral sciences (observations outside of lab) o Earth sciences o There is an interdisciplinary focus on sciences now Look at the "big picture" and how things interact Research: Basic and Applied: o Basic - understanding a certain phenomenon; "pure", curiosity driven Ex.: understand fundamental nature of matter o Applied - real-world application of basic research; tries to solve a problem Ex.: studies of nuclear weapons, medicine, etc. o Both are intertwined!!! o We never know what we need to know so research simply for curiosity should be encouraged Scientific Statements: o Attempts to explain or understand real phenomena Ex.: F = ma or pv = nRT o For a statement to be scientific it must be testable, measureable, and reproducible o Scientists must consider the probability of a scientific statement being false There are no "absolute truths" Scientific Knowledge: o An on-going process where knowledge is gained and built upon through research Scientific Methods: o Has evolved in to a system in which the likelihood of being wrong is reduces by methods used by scientists
