ABSTRACT
Whenever physicists think about a perfect set of experimental values, they dream of something called the normal distribution curve, as illustrated in Figure 13.1.
In this case we are supposed to imagine that Figure 13.1 represents the results of identical measurements made on a collection of objects. We are not just talking about quantum systems being measured here. e normal distribution applies to the experimental results found in classical physics as well, although for di erent physical reasons.
