In this lesson, our instructor Bryan Cardella gives an introduction on the scientific method. He explains the origin and steps of the scientific method, inductive and deductive reasoning, theories and models, uncertainty and accuracy, and pseudoscience.
The scientific method has its origins in Babylonia and Ancient Egypt. Much of its influence in modern science comes from Ancient Greece. The Scientific Revolution (Galileo, Gilbert, Harvey, Bacon) helped make it what it is today. Scientific investigation is a process that involves testability and disprovability
The steps of the scientific method include: observe, question, hypothesize, experiment (with a control and experimental group, involving independent and dependent variables), interpret data, and draw conclusions
Science is based on inductive reasoning. Proof with inductive reasoning is not absolute, but it has a high degree of probability
Scientific research leads to theories and theories can lead to more research. Models (such as computer simulations) can make sense of data and even project future data based on extrapolation
Science has a fair degree of confidence but it does not explain everything 100% of the time. Objectivity is the goal with data. Data is measured with a degree of uncertainty (in order for it to be meaningful.) Accuracy and precision are important to consider
Pseudoscience is false science not based on reliable data.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
