More than one scholar has tried to apply physics and algebraic relations to love and its dynamics to get more information. It is a misconception: "Thanks to mathematics, we can predict a number of phenomena - from the time meteorological development of the cities - and understand the workings of nature in every level by the immensity of the universe to the subatomic particles , writes Hannah Fry, researcher of Mathematics and complexity theory at the Center of advanced spatial Analysis at University College London and author of the love math.

Several scholars have sought to better understand the love through mathematics. One of these is the English Hannah Fry mathematics. |

In search of the equation of life. "Fortunately, love is full of patterns of behavior, the number of sexual partners we have in the course of our lives the way we choose the people with whom to exchange messages on a dating website. These patterns change, they change over and over again and evolve just like love. Their description is within the reach of mathematics. "

So much so that many scholars, calculator in hand, tried to measure this universal feeling and answer the questions that frequently arise lovers. Knowing, for example, if what you feel for someone is a true feeling.

I thought it was love, but ... He did it, for example, Donn Byrne, a social psychologist at the State University of New York at Albany, United States: has developed a formula that allows anyone to check whether what we feel for the partner's true love or not. The formula is this:

In this formula, A is the attraction for the partner, B the psychological pleasure of her company, C desire for intimacy with him / her, the D need to be accepted by the partners, and the fear of being abandoned by him / her . At each of these variables must be attributed a value from 1 to 10 and then do the calculation.

Once performing the calculations, you get a number Y. must then repeat the operation thinking friend / a more expensive / a. According to Byrne, the relationship is much more stable as much as the difference between the two results Y is large (must be at least 15). That is, the more the partner is more important than friendship dear. The multiplication factors (the numbers in front of the variables) allow to compare many friendships and loves.

Snuggle-insults 5 to 1. Mathematics can also help to stabilize an idyll. At least according to John Gottman, now Emeritus Professor of Psychology at the University of Washington, who has dedicated his life to studying what can "hold" a couple and under what conditions. Gottman wrote these formulas:

The first means that the life together, the affection signals (S) that is, petting, cuddling, knowing glances, must be at least five times more numerous than those of resentment (G) that shouts, nasty comments etc ... The second means that, each 100 comments about the partners, negative (N) must be less than ten. If these conditions are met, the couple will stand. |

Parabola insecurity. And there are people who want to write a formula for love, but prefers to track its progress over time. Maybe to predict how it will stabilize the relationship. Sergio Rinaldi, Professor of System Theory at the Polytechnic of Milan, has transformed the various types of reports in differential equations similar to those used to describe the motion of planets. thus you can sum For him, love:

It means that love (A) you feel for your partner on any given day (t) is equal to the love of the previous day (t-1) decreased by forgetfulness (D), the tendency we all have to do mental space for ourselves, plus the reinforcement (R) given by a loving partner to us, the more charm (F) that the partner has on us. |

In reality, the mathematical model is much more complex, because both the forgetfulness both the charm both the reinforcement are also described by differential equations. "It can be shown mathematically that if the partner becomes beautiful or elegant dress, thus increasing its appeal, this does fall in love with the onlookers. If the total love of elegant partner grows by 2 percent, that of his Spouse / Partner grew by 5 percent, "continues Rinaldi. Even more complicated is to trace the progress of a love triangle: the scholar has even used the mathematics of chaos. For example, in the case of a woman tied to two men, preference oscillates like a wave between the one and the other.

The stable marriage. Other studies turn into figures marital relationships. According to Zick Rubin, Professor of Psychology at Harvard, you can estimate the chances of survival of a couple based on the number of looks that the partners exchange. The more, the more likely that the two will stay together.

The physicist Guido Caldarelli Institute for Advanced Studies Lucca, and Andrea Capocci, a researcher at the University Sapienza of Rome, have instead developed an algorithm called Stable Marriage Problem (problem of stable marriage), devised by the American mathematicians David Gale and Lloyd Shapley in the '60s: "We have introduced the beauty factor in the algorithm. Put simply, we have three men (Charles, Peter and Andrew) and three women (Anna, Laura and Mary). Each of these people have their own preferences. We have to find pairs that satisfy as many people as possible. If everyone married the preferred partner, discontent would be minimal. But if Anna, for example, was really cute, it would be the first or second on the list of many men and someone should be content. " So this is the mathematical proof that to build a solid relationship over time we must remain "at his level".

Quantum Physics. And there are those who wanted to see in an equation of quantum physics the definition of a loving relationship. The equation is the Dirac (British mathematician Paul Dirac wrote it in 1928), called "the most beautiful formula in the world." Here she is:

The equation also describes the phenomenon of quantum entanglement, hypothesized by Erwin Schrdinger in 1935 and which in simple words can be described as follows: if two microscopic particles interact with each other for a certain period of time with a certain mode, and then are separated , you can no longer be described as two distinct particles, but somehow "share" some properties. |

What happens to one of them continues to influence each other, but only as long as they are isolated. In the moment in which the two particles interact with the external environment, become again two independent particles. A little 'what happens to two people who meet and fall in love Even though life away, continue to have something from each other.

"Entanglement, one of the features of quantum mechanics, only applies to atomic and subatomic systems and photons, or at most in groups of very cold atoms, so you can not automatically extend to macroscopic objects, let alone to human relationships" , says Carlo Cosmelli, professor of the Physics Department of Sapienza University of Rome. In addition, to emphasize the relation between entanglement and love is mentioned especially the Dirac equation, but "although the Dirac equation is a very elegant extension of the relativistic Schrdinger" continues Cosmelli, "it is not necessary to describe this phenomenon".
