Here is a little bit about the science we all love:
Numerology deals with the nine major planets of the Universe and their characteristic features. The planetary position at the time of a person's birth ascertains the personality of that individual. These planets are given numerical values depending on their vibrations in relation to the number. The characteristics of the individual, ranging from thinking, reasoning, emotions, philosophy, desires, aversions, health, career, etc. are all dominated by these numbers or their corresponding planets.
Pythagoras, the Greek mathematician who lived from 569-470 B.C., is generally accepted as the "father" of Numerology. But there is evidence that numerology was in use much before in China, Greece, Rome, and Egypt. The actual origins of numerology predate Pythagoras, the most popular being from the Hindu Vedas. Numerology is based on Pythagoras belief that reality is mathematical. For their readings, modern numerologists adopt the original Pythagorean system in which a number value ranging from one to nine is assigned to every letter of the alphabet: A is 1, B is 2, C is 3 and so on for interpretation purpose.
There is much more and I would like to learn it. Feel free to add.
