PHYC 101 Lecture
August 23, 2016
Points of Focus:
What is science?
What is physics?
The metric system
Notes:
What is science?
oMost definitions of science include action words (e.g. study, discover,
etc.)
oScience explains everything that we observe in our lives and help us
to predict the universe’s behavior.
oWe need models to explain phenomena & science is the process of
creating these models.
Types of models:
physical
gestural / visual
verbal / written
pictorial
numerical
graphical
mathematical (equations, etc.)
Potential problems with models
1. No model can represent a phenomenon EXACTLY, so it
made lead to assumptions.
You have to make compromises in how you
construct models.
2. Many people confuse scientific models with reality.
For example: ray model of light, flat maps of Earth,
etc.
Parallels between scientific models and teaching
