Is measure here a plain english or the measure in measure theory?

Plain English... – Mauro ALLEGRANZA Dec 12 '19 at 07:00

1It's english. I do think that it is the best word to use in the context; it's unfortunate that it also happens to have a different technical meaning. – Rushabh Mehta Dec 12 '19 at 07:02

The cardinality is the number of elements in a set. So just plain english measure. – Edcookie274 Dec 12 '19 at 07:02

1@Edcookie274 I like the word measure better than number, personally. But yes, you are right. – Rushabh Mehta Dec 12 '19 at 07:03

In measure theory, we formalize the intuitive notion of "measure" of a geometrical shape. In set theory we formaluize the intuitive notion of "measure" of a collection of objects, i.e. the number of its elements. – Mauro ALLEGRANZA Dec 12 '19 at 07:39
