 If one feels that statements about inaccuracy of measurement, or the possibility of simultaneous measurements, belong to any satisfactory formulation of the uncertainty principle, one will need to look for other formulations of the uncertainty principle. Some candidates for such formulations will be discussed in  Section 6.  First, however, we will look at formulations of the uncertainty principle that stay firmly within the minimal interpretation, and differ from  (9)  only by using measures of uncertainty other than the standard deviation.
