What is Science?

Physics – A Scientific World View What is Science? Discover and study nature’s rules

Physics – A Scientific World View What is Science? A body of knowledge The method to produce it Body of Knowledge Methods

Scientific Method

Physics – A Scientific World View Scientific Method Galileo Galilei & Francis Bacon are the principal founders of the scientific method

Physics – A Scientific World View During the Do. Now exercise, which steps have we taken to determine the contents of the bottle? Discuss it with your partner and share them with the class.

Physics – A Scientific World View Scientific Method

Physics – A Scientific World View Scientific Method Observe Develop Experiments Recognize a problem Formulate Rules Develop a Hypothesis Refine the Hypothesis Predict Consequences Publish Results

Physics – A Scientific World View Scientific Method Effective in gaining, organizing & applying new knowledge The method is only a guideline to a good scientific practice

Physics – A Scientific World View Scientific Method Einstein’s view of scientific processes Idea/Axiom Creative Leap Consequences The Real World

Physics – A Scientific World View Scientific Method Einstein’s view of scientific processes ☛ A scientist makes a creative leap based on intuition to explain physical phenomena ☛ The scientific process begins when the scientist develops consequences based on the idea/axiom ☛ A powerful idea/axiom has many consequences ☛ Test these consequences against the real world

Goal of Physics

Physics – A Scientific World View The Goal of Studying Physics To create a scientific world view

Physics – A Scientific World View The Goal of Studying Physics World view – A shared set of ideas that explain how the material world operates

Physics – A Scientific World View The Goal of Studying Physics Scientific world view vs. Common sense – sometimes the ideas might appear to be contrary to common sense Common Sense Scientific World View

Physics – A Scientific World View The Goal of Studying Physics Scientists use instruments to extend the range of human sensations

Scientific Attitude

Physics – A Scientific World View Scientific Attitude Fact – A close agreement by competent observers who make a series of observations of the same phenomenon Fact

Physics – A Scientific World View Scientific Attitude Hypothesis – An educated guess that is only presumed to be factual until demonstrated by experiment Scientific hypotheses must be testable Hypothesis

Physics – A Scientific World View Scientific Attitude Laws or Principles – Hypotheses being tested repeatedly and not contradicted Law/Principle

Physics – A Scientific World View Scientific Attitude Theory – A synthesis of a large body of information that includes well-tested hypotheses about certain aspect of the natural world Theory

Physics – A Scientific World View Scientific Attitude Concept – An intellectual framework that is part of a theory encompasses the overriding idea that underlines various phenomena Concept

Physics – A Scientific World View Scientific Attitude Not appealing to authority, personal preferences, popularity or selecting partial facts STOP
