Section 11.1 What are dimensions, really?
Objectives
Interpret dimension as the number of values needed to describe a state.
Identify real-world contexts that naturally give rise to additional dimensions.
Apply spatial intuition to conceptualize non-spatial dimensions such as time.
Dimensions are just a measure of how many numbers you need to specify a state.

Give multiple real-world examples
Don’t have to be spatial dimensions, but our spatial intuition can give us insight on how we can understand non-spatial variables (e.g. using a time axis)
