Abstract
The flux from a particular high-redshift galaxy, or the combined flux from some sample of galaxies, can be considered to be a stream of information about the distant Universe. The stream can be so diluted by the expansion of the Universe that random errors due to photon counting statistics become important and need to be accounted for in the comparison of models with data. Computing the photon statistics is elementary, but its elaboration is still worthwhile to support a number of arguments made in these lectures.
