new Vector3(x, y, z)

-This is how specify positions in 3D space
-Creates a new Vector3 object
-First number is the x coordinate
-Second number is the y coordinate
-Third number is the z coordinate

Quaternions
-How Unity handles 3D rotations
-Better for simulations than Euler angles
-Unity handles all the complicated math

Comments
-Great way to write programming notes to yourself and others
-Also useful for saving code for later reference
