+### Lab #1 - Measurements of machining precision and accuracy
+
+[Lab 1 github files](https://github.uconn.edu/rcc02007/ME3263_Lab-01.git)

+**Outline and figures due in week 4 at beginning of lab**
+
+**Final report due day before lab by 11:59pm**
+
+**How can you measure something?** 
+
+All measurements have traceable standards. There are seven base units in SI -
+meter (length), second (time), Mole (amount of substance), Ampere (electric
+current), Kelvin (temperature), Candela (Luminous intensity), and kilogram
+(mass) 1. Any measurement you make should have some method to check against a
+reference. In this lab, we will use calipers that measure dimensions i.e.
+meter 1E-3 (length). Calipers can always be verified to work with gage
+blocks.
+
+**Sources of measurement variations**
+
+No measurement is exact. No surface is compeletely flat. Every measurement you
+make has two types of uncertainties, systematic and random. Systematic
+uncertainties come from faults in your assumptions or equipment.
