The numbers
are magical. Pythagoras was the Greek mathematician of the VI century before
Christ, who collected and systematized certain teachings that inspired in part
what is currently known as traditional numerology. For Pythagoras, numbers make
up the universe and govern the existence: everything that exists in the world
is governed by a number that describes its nature and constitutes its essence.
The traditional Numerology looks for a numerical sense to everything and tries
to explain this sense with associations that are based on the primitive
Pythagorean explanations. With the passage of time it has been enriched, with
other meanings of diverse origin.
Cardinal numbers and ordinals
In linguistics, the natural integers one, two, three, four, five… are called adjectives cardinal numerals. In mathematics a cardinal number is an extension of this notion to name certain sets, even the infinite sets.
For
example, 7 days a week, 7 capital sins, the 7 hills of Rome, are three sets
that share an attribute that is not shared with the 5 fingers of the hand, the
5 senses or the 5 geographic continents. You can put in evidence this quality
by matching one by one to the respective elements of these sets. It can be said
that "seven" is the cardinal number that corresponds to the days of
the week, the capital sins and to the hills of Rome. As the cardinal number
"five" is a quality that corresponds to the fingers of the hand to
the senses and the geographic continents. "Seven" and
"Five" are in this case an essential property of these sets.
Each of the
fingers of the hand can be matched with an element of the whole of the
continents: America, Antarctica, Africa, Eurasia, Oceania. There is a certain
one-to-one correspondence between each item in the set of the fingers of the
hand with the set of the continents. To each one of the five fingers of the
hand we can match one of the continents. In this sense one can say that there
is an equivalence relation between them. In mathematics can be said that it
establishes a new relationship between them bijective, or also that these sets
are equipotential.In Mathematics is called ordinal number to a logical object that allows you to set a certain type of order in a set. As in linguistics the words "first, second, third, fourth, fifth, sixth…," are called numerals ordinal adjectives and serve to clarify the range of an item in a collection or the order of an event in a succession. The finite ordinal numbers can be identified with the natural integers, who identify themselves with the cardinal numbers finite. But this identification is not true in the case of infinite sets, since the cardinal numbers correspond to the ordinal numbers but the reciprocal is false.
