Prologue


The scientific method

The Scientific Method

  • A methodology for exploring phenomena

  • Terms:

    • Hypothesis – an educated guess that is testable.

    • Law (Principle) – a scientific hypothesis that has been repeatedly tested and has not been contradicted.

    • Fact - something that competent observers can observe and agree to be true.

    • Theory – a synthesis of facts and well-tested hypotheses.


The scientific method1

The Scientific Method

  • Recognize a question or a problem.

  • Make an educated guess – a hypothesis – to answer the question.

  • Predict what can be observed if the hypothesis is correct.

  • Do experiments to see if the predicted effects are present.

  • Formulate the simplest general rule that integrates the hypothesis, the predicted effects and experimental findings.


Scientific hypotheses

Scientific Hypotheses

  • The hypothesis must be testable.

  • A hypothesis can be wrong.

    • Aristotle thought that heavier objects would fall faster than light objects. It seemed to be logical – however:

    • Galileo was a skeptic. He dropped heavy and light objects from the Tower of Pisa. They all fell at the same speed.

  • If the hypothesis is proven wrong, a new hypo-thesis can be formulated (back to the drawing board!).


What is good science

What Is Good Science?

  • Scientists must be open to debate. Debate is a means of testing hypotheses.

  • Scientists must be willing to publish their experimental procedure so that others may have an opportunity to reproduce results.

  • Scientists must have integrity. They must publish experimental findings even if those findings do not support the hypothesis.

  • Consensus is not science! There was once consensus that the Earth was flat!


Technology

Technology

  • Science and Technology are not the same.

  • Science is concerned with gathering knowledge and organizing it.

  • Technology puts scientific knowledge to practical use.

  • Technology is a tool.
