+We use statistics to draw conclusions from limited data. No measurement is
+exact. Every measurement you make has two types of uncertainties, *systematic*
+and *random*. *Systematic* uncertainties come from faults in your assumptions or
+equipment. 
+*Random* uncertainties are associated with unpredictable (or unforeseen at the
+time) experimental conditions. These can also be due to simplifications of your
+model. Here are some examples for caliper measurements:
+
+In theory, all uncertainies could be accounted for by factoring in all physics
+in your readings. In reality, there is a diminishing return on investment
+for this practice. So we use some statistical insights to draw conclusions.
