-The ``arange`` function returns an array with range from 0 to 2000 in
-steps of 20.  It is necessary to say 2001 (or 2002, 2000.1 or whatever)
-and not 2000, if you want the range to be inclusive.  The ``hist``

+The ``linspace`` function returns an array with range from 0 to 2000 with a
+total number of 101 values. The first value is 0, the last is 2000. These are
+the *edges* of the bins. So, 101 values means exactly 100 bins between 0 and
+2000. The ``hist`` function will then plot a *stepped* histogram with a log
