past the saddest day of the year. January 17: "Blue Monday"

Yes, again Mathematics justify if yesterday Monday January 17 you felt by Soil

"In 2005 the researcher Cliff Arnal of Cardiff University (United Kingdom), obtained with a formula in which combines climate, salary, time elapsed since Christmas and debts that the third Monday of each year is the saddest day the same.

W, indicates weather conditions, the D, debts incurred at Christmas, T, time since it finished the holiday and Q next pay . also took into account other factors such as the fact of that failure to successfully carry out New Year's resolutions and have low levels of motivation. "

would be interesting to see how this scientist would weigh in the formula the current crisis.
Although more interesting is to know who is behind this study: a travel company "Sky Travel" .

And if after this trip suggested, is that your marriage is wrong, again uses mathematics as a marriage counselor.

mathematician James Murray ensures that a simple mathematical model developed with colleagues the University of Oxford (UK) has been predicted divorce rates with an accuracy of 94 percent.

• For women, the formula is: w (t +1) = a + r1 * w (t) + IHW [h (t)] , in which: w = female, h = husband t = time, to = a constant representing the mood of women when not with her husband, r1 * w (t) = represents how easy is to change your mood when talking to her husband, IHW = " of the influence ", a measure of the influence that the husband has on women, h (t) = husband score after 15 minutes of conversation with her, w (t +1) = woman's reaction after the talk with her husband. After entering the parameters, the higher the resulting number is more likely to divorce marriage.

• As to husband, the equation is: H (t +1) = b + r2 * h (t) + IWH [w (t)] , which b constant that represents the mood of the husband when not with his wife, r2 * h (t) = represents how easy it is to change your mood when talking to his wife, IWH = " influence function, which measures the influence women have on the husband , w (t) = women score after 15 minutes of conversation with him, H (t +1) = how the husband reacts after the talk. As with the above equation, the higher the number the more likely result of failure.

So it is no surprise that a American psychologist John Gottman, applying the second law of thermodynamics to love is won good living since 2002 in a marriage consultancy in Seattle.

The Russian mathematician Lev Pontryagin died in 1988, never imagined that his theory of optimal control, lit to solve a contretemps with a Soviet fighter aircraft would be used to explain why in Spain there is a divorce every 80 seconds. But Professor José Manuel Rey, the Universidad Complutense de Madrid He has done. And mathematics has spoken: "To have a lasting and fulfilling romantic relationship is impossible, few exceptions."

King has put in a blender the second law of thermodynamics and Pontryagin equations to explain the so-called failure paradox: many people in love get married and commit to live together forever, but still and their marriage is a wreck.

needed a sacrifice, of course, but how has to be this effort to shore up a relationship forever? Its beautiful theoretical model, embodied in the scientific journal PLoS ONE an integral equation and unintelligible to anyone outside of mathematics, shows "a diabolical mechanism means that, although one case very much in love and very well designed effort, very easy to fail. "

By introducing variables such as positive feelings produced by the relationship and the cost of the effort to keep alive the flame, the machine spat out Pontryagin theoretical three conclusions not so obvious. The first, as King points out, is that among all the ways to strive to sustain a relationship, only one will work, but the equation does not say which. Second, the effort required will always be greater than expected. And finally, it is essential to maintain lifelong effort to overcome the natural inertia, as shown by equations Rey, leads inexorably to the neglect within the family.

formulas that, if we do not worth to explain our emotions, certainly entertain and make us forget this, since last Monday sad.

(I confess my particular secret: instead of having multiplied the defects, I count maximizing the virtues, so always get a positive difference, and if even then:! I apply an absolute value!. Always positivized.)
