Numerology is the belief in the divine or mystical relationship between a number and one or more coinciding events. It is also the study of the numerical value of the letters in words, names, and ideas. It is often associated with the paranormal, alongside astrology and similar to divinatory arts.
Despite the long history of numerological ideas, the word "numerology" is not recorded in English before c. 1907.
The term numerologist can be used for those who place faith in numerical patterns and draw pseudoscientific inferences from them, even if those people do not practice traditional numerology. For example, in his 1997 book Numerology: Or What Pythagoras Wrought, mathematician Underwood Dudley uses the term to discuss practitioners of the Elliott wave principle of stock market analysis.
Pythagoras and other philosophers of the time believed that because mathematical concepts were more "practical" (easier to regulate and classify) than physical ones, they had greater actuality. St. Augustine of Hippo (AD 354-430), wrote: "Numbers are the Universal language offered by the deity to humans as confirmation of the truth."[dubious ] Similar to Pythagoras, he too believed that everything had numerical relationships and it was up to the mind to seek and investigate the secrets of these relationships or have them revealed by divine grace.
In 325 AD, following the First Council of Nicaea, departures from the beliefs of the state church were classified as civil violations within the Roman Empire. Numerology had not found favor with the Christian authority of the day and was assigned to the field of unapproved beliefs, along with astrology and other forms of divination and "magic". Despite this religious purging, the spiritual significance assigned to the heretofore "sacred" numbers had not disappeared; several numbers, such as the "Jesus number" have been recognized and analyzed by Dorotheus of Gaza. Numerology remained in use in conservative Greek Orthodox circles. Despite the church's resistance to numerology, there have been arguments made for the presence of numerology in the Bible and religious architecture.
For example, the numbers 3 and 7 hold strong spiritual meaning in the Bible. The most obvious example would be the creation of the world in 7 days. Jesus asked God 3 times if he could avoid crucifixion and was crucified at 3 in the afternoon. 7 is the length of famine and other God-imposed events and is sometimes followed by the number 8 as a symbol of change.
Some alchemical theories were closely related to numerology. For example, Persian-Arab alchemist Jabir ibn Hayyan framed his experiments in an elaborate numerology based on the names of substances in the Arabic language.
Numerology is prominent in Sir Thomas Browne's 1658 literary Discourse The Garden of Cyrus. Throughout its pages, the author attempts to demonstrate that the number five and the related Quincunx pattern can be found throughout the arts, in design, and in nature - particularly botany.
Modern numerology has various antecedents. Ruth A. Drayer's book, Numerology, The Power in Numbers states that, around the start of the 20th century, Mrs. L. Dow Balliett combined Pythagoras' work with Biblical reference. Balliett's student, Juno Jordan, helped numerology become the system known today as Pythagorean numerology (although Pythagoras himself had nothing to do with the system), by publishing "The Romance in Your Name" in 1965, providing a system for identifying what he called key numerological influences in names and birth dates that remains used today.
Other numerologists including Florence Campbell (1931), Lynn Buess (1978), Mark Gruner (1979), Faith Javane and Dusty Bunker (1979), and Kathleen Roquemore (1985) expanded on the use of numerology for assessing personality or events. These different schools of numerology provide various methods for its use.
There are various numerology systems which assign numerical value to the letters of an alphabet. Examples include the Abjad numerals in Arabic, Hebrew numerals, Armenian numerals, and Greek numerals. The practice within Jewish tradition of assigning mystical meaning to words based on their numerical values, and on connections between words of equal value, is known as gematria.
There are various systems of numerology that use the Latin alphabet. Different methods of interpretation exist, including Chaldean, Pythagorean, Hebraic, Helyn Hitchcock's method, Phonetic, Japanese, Arabic and Indian.
This method is referred to as either Eastern Mediterranean numerology or Pythagorean numerology. Pythagoras, the Greek mathematician and philosopher who lived from 569 to 470 BC, is known as the father of Western numerology. Pythagoras began his theory of numbers by discovering the numerical relationship between numbers and musical notes. He found that the vibrations in stringed instruments could be mathematically explained. The Pythagorean method uses an individual's name and date of birth. The name number reveals the individual's outer nature. This is the personality that they present to the outside world. To start, one needs to use the individual's full name as written on their birth certificate. Then, each letter is assigned to a digit, based on the Pythagorean system. The numbers are assigned to letters of the Latin alphabet as follows:
Next, add together all of the numbers associated for each letter in the individual's full birth name. Then, the number is reduced until one obtains a single digit.
Example: James Duncan Helpert
Then, James Duncan Helpert's name number is 9.
A quicker way to arrive at a single-digit summation (the digital root) is simply to take the value modulo 9, substituting a 0 result with 9 itself. As mentioned before, the single digit then arrived at is assigned a particular significance according to the method used.
When someone changes their name they will receive a new name number. This is believed to change certain parts of the individual's personality and destiny. Next, the birth number is viewed as an extension of the name number. This number represents the traits/talents that the individual desires to have. It is believed that an individual's birth number reveals their inner nature and life purpose. To find the birth number, one adds together all the numbers in the month, day, and year the individual in question was born. Then, that number is reduced to a single digit number.
In the Pythagorean system, there are three master numbers (11, 22, 33) which do not get reduced to a single number. Hence, if one's name number or birth number comes out to one of these master numbers, then they shall not be combined to form a single digit. Finally, the single digit name number and birth number are assigned a particular meaning and significance based on the Pythagorean system.
The Chaldeans were ancient people who ruled Babylonia from 625 to 539 BC. Therefore, this system is also known as the Babylonian numerology system. Chaldean numerology is used to recognize the energy changes that occur when someone speaks or thinks. The sound of someone speaking comes out in vibrations of different frequencies that affect the speaker and those around them.
The Chaldean system uses the numbers 1-8. The number 9 is not used in the system because it is regarded as sacred due to its connection to infinity. The Chaldean system uses this 1-8 number system on the name that the individual is currently using because that is the energy that would currently be projected. Then, each letter is assigned to a number one to eight, based on the Chaldean numerology chart. The numbers are assigned to letters of the Latin alphabet as follows:
Example: Assume James Duncan Helpert normally goes by Jim.
Then, Jim Duncan Helpert's name numbers are 6, 6, and 5.
The Chaldean system recognizes the same master numbers that were present in the Pythagorean system (11, 22, 33), which do not get reduced to single digits. In the Chaldean system, an individual's first name is their social persona and how they present themselves in public and the energy that comes with that. The first name also indicates the individual's personal interests and habits. The middle name is the soul energy and it reveals the truth about an individual's inner soul and their deepest parts. The middle name shows the hidden talents, desires, and what one's soul is trying to reach for. The last name is related to the domestic influence of the family.
In the advanced Chaldean system, numbers higher than ten are considered. Here one looks at all the digits and the digital root. For example, if one analyzes the number 23, it is referred to as 23/5 (because 2 + 3 = 5). Then the influence of the single numbers 2, 3 and 5 is recognized, so it becomes more complex than Pythagorean numerology.
In advanced Chaldean numerology, one works with an advanced formula called the numeroscope which is divided into the "highest self", the "higher self" and the "human self". The "highest self" is a calculation of the person's full birthdate independent from his/ her name. The "human self" is a formula of the number combinations between the person's birth date and his/ her full legal name. The "higher self" is considered to be the gateway between the will of the soul to the human experience.
In advanced Chaldean numerology, one also works with a formula that is believed to be able to predict the past, the present and the future. This is called year ranks, and these are mathematical formulas that connect the sum number of the year with the individual's birth date, the sum number of his/ her names, and the sum of his/ her age that year. Here it's believed that these numbers can tell what happens or had happened in any given month.
The Arabic system of numerology is known as Abjad notation or Abjad numerals. In this system each letter of Arabic alphabet has a numerical value. This system is the foundation of ilm-ul-cipher, the Science of Cipher, and ilm-ul-huroof, the Science of Alphabet:
?=9 ?=8 ?=7 ?=6 ?=5 ?=4 ?=3 ?=2 ?=1
?=90 ?=80 ?=70 ?=60 ?=50 ?=40 ?=30 ?=20 ?=10
?=900 ?=800 ?=700 ?=600 ?=500 ?=400 ?=300 ?=200 ?=100
Some Chinese assign a different set of meanings to the numbers and certain number combinations are considered luckier than others. In general, even numbers are considered lucky, since it is believed that good luck comes in pairs.
Traditional Chinese Medicine (TCM), and its associated fields such as acupuncture, base their system on mystical numerical associations, such as the "12 vessels circulating blood and air corresponding to the 12 rivers flowing toward the Central Kingdom; and 365 parts of the body, one for each day of the year" being the basis of locating acupuncture points.
Cantonese frequently associate numbers with the following connotations (based on its sound), which may differ in other varieties of Chinese:
Some "lucky number" combinations include:
1 = A, I, J, Q, Y
2 = B, K, R
3 = C, G, L, S
4 = D, M, T
5 = E, H, N, X
6 = U, V, W
7 = O, Z
8 = F, P
There is no assignment for the number 9. Numerologists analyze double-digit numbers from 10 to 99.  Ex: Number 29 is supposed to be the worst numbered-name a person can have.
Scientific theories are sometimes labeled "numerology" if their primary inspiration appears to be a set of patterns rather than scientific observations. This colloquial use of the term is quite common within the scientific community and it is mostly used to dismiss a theory as questionable science.
The best known example of "numerology" in science involves the coincidental resemblance of certain large numbers that intrigued such eminent men as mathematical physicist Paul Dirac, mathematician Hermann Weyl and astronomer Arthur Stanley Eddington. These numerical coincidences refer to such quantities as the ratio of the age of the universe to the atomic unit of time, the number of electrons in the universe, and the difference in strengths between gravity and the electric force for the electron and proton. ("Is the Universe Fine Tuned for Us?", Stenger, V.J., page 3).
The discovery of atomic triads, an early attempt to sort the elements into some logical order by their physical properties, was once considered a form of numerology, and yet ultimately led to the construction of the periodic table. Here the atomic weight of the lightest element and the heaviest are summed, and averaged, and the average is found to be very close to that of the intermediate weight element. This did not work with every triplet in the same group, but worked often enough to allow later workers to create generalizations.
Large number co-incidences continue to fascinate many mathematical physicists. For instance, James G. Gilson has constructed a "Quantum Theory of Gravity" based loosely on Dirac's large number hypothesis.
British mathematician I. J. Good wrote:
There have been a few examples of numerology that have led to theories that transformed society: see the mention of Kirchhoff and Balmer in Good (1962, p. 316) ... and one can well include Kepler on account of his third law. It would be fair enough to say that numerology was the origin of the theories of electromagnetism, quantum mechanics, gravitation.... So I intend no disparagement when I describe a formula as numerological.
When a numerological formula is proposed, then we may ask whether it is correct. ... I think an appropriate definition of correctness is that the formula has a good explanation, in a Platonic sense, that is, the explanation could be based on a good theory that is not yet known but 'exists' in the universe of possible reasonable ideas.
Numerology is a popular plot device in fiction and superstitions. Sometimes it is a casual element used for comic effect, such as in an episode titled "The Séance" of the 1950s TV sitcom I Love Lucy, where Lucy dabbles in numerology.
Sometimes it is a central motif of the storyline, such as the movie Pi, in which the protagonist meets a numerologist searching for hidden numerical patterns in the Torah; the TV show Touch which focuses almost entirely on the role of numerology in the events and coincidences of any person's life; and the movie The Number 23, based on claimed mysteries of the number 23 (itself based on the Law of Fives).
Numerology is a topic taught in the Arithmancy class in the Harry Potter series of books. In Harry Potter and the Prisoner of Azkaban, the third book of the series, Arithmancy is offered as an elective course. In Harry Potters world, Arithmancy was used as the practice of assigning numerical value to words in order to predict the future.
