Revealed: The mathematical formula that predicts the best age to get engaged

The EDATE function is fully automatic, and will return a date xx months in the future or past, when given a date and the number of months to traverse. In this case, we want a date 60 years in the future, starting with a birthdate, so we can write a formula like this for the data in the example:. The date comes from the birth dates in column C. For months, we need the equivalent of 60 years in months. Since you probably don’t know how many months are in 60 years, a nice way to do this is to embed the math for that calculation directly in the formula:. You can use this same approach to calculate age from birthdate. What if you just want to know the year of retirement? In that case, you can format the date returned by EDATE with the custom number format “yyyy”, or, if you really want only the year, you can wrap the result in the YEAR function like this:.

Top definition. A convenient rule to define the youngest that a romantic interest can be before the relationship is indecent. Widely referred to and used, the rule has merit for usefulness. The full version states: “if you halve your years then add seven, you’ll have the youngest decent age for a partner; if you double your years then subtract seven, you’ll have the oldest decent age for a partner”. However it’s somewhat flawed thanks to the poor mathematical ability of its authors — it gives a different result depending on whether it is worked out for a younger or older partner.

Half your age plus seven rule.

The equation claims to predict the best age to get engaged with the promise of a long and happy marriage. Boffins in Australia have come up with a quirky equation they say will predict the best age to get engaged with the promise of a long and happy marriage. The formula is based on a similar equation used in the finance and medical sectors to pinpoint when to take action to maximise rewards and minimise costs. Choose the oldest age by which you want to get married, for example Call this number ‘n.

Decide the earliest age at which you’ll start to consider women as potential wives, for example, from 20 onwards. This number becomes ‘p’. Subtract ‘p’ from ‘n’ 20 from 39 then multiply the result by 0. This gives you 6. The result of 27 more or less is your Optimal Proposal Age.

Scientists Reveal How to Choose the Perfect Partner Before You Turn 35

Ever heard of the rule that men should date women who are half their age plus seven? Some celebrities – think Leonardo Di Caprio – take this to extremes with a roster of something models regularly appearing on their arm, but do you know where the saying comes from? But does it stand up to scrutiny, or is it just a baseless rule perpetuated by men who want to justify dating younger, and less mature, women? We asked three relationship experts to weigh in on the rule – and their responses were surprising.

Historically, a woman was to choose a man the same age, or five to 15 years older.

Your pet clearly ages faster than you do, but new research is giving us a much clearer The age you feel means more than your birth date That formula is: human equivalent age = 16 x ln(dog’s chronological age) + Christian Yates is a senior lecturer in mathematical biology at the University of Bath.

Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and it can be used to date a wide range of natural and man-made materials.

The best-known radiometric dating techniques include radiocarbon dating, potassium-argon dating, and uranium-lead dating. By establishing geological timescales, radiometric dating provides a significant source of information about the ages of fossils and rates of evolutionary change, and it is also used to date archaeological materials, including ancient artifacts. The different methods of radiometric dating are accurate over different timescales, and they are useful for different materials.

In many cases, the daughter nuclide is radioactive, resulting in a decay chain. This chain eventually ends with the formation of a stable, nonradioactive daughter nuclide. Each step in such a chain is characterized by a distinct half-life. In these cases, the half-life of interest in radiometric dating is usually the longest one in the chain. This half-life will be the rate-limiting factor in the ultimate transformation of the radioactive nuclide into its stable daughter s.

Systems that have been exploited for radiometric dating have half-lives ranging from only about 10 years e. However, in general, the half-life of a nuclide depends solely on its nuclear properties and is essentially a constant.

Lead–lead dating

Okay, go on. This led me on a rabbit hunt through the internet to understand where that number the 37 percent came from. This is also where the concept of e started to go a little over my head and I stopped Googling. I did enjoy this simplified example of the setup, though, which is also called the Secretary Problem , from Scientific American in

In this section we will explore the use of carbon dating to determine the age of decay to calculate the amount of carbon at any given time using the equation.

The “creepiness rule” states that the youngest you should date is “half your age plus seven. According to this rule, society should accept a 50 year old man dating a 32 year old woman. A quick poll of my friends says otherwise. This made me wonder, does the creepiness rule actually reflect what is socially acceptable when it comes to age differences in dating? In other words, does the creepiness rule actually reflect what society finds…creepy? The internet is divided on the topic.

The researchers approached random people in public and asked them to imagine themselves in a romantic relationship with an attractive person of the opposite sex. The researchers then presented different types of relationships- sexual fantasies, casual affairs, long-term relationships, marriage – and asked the participants what the minimum and maximum age of their partner is for each scenario. Women want men around their own age regardless of the type of relationship.

Men want much younger women for less committed, more private relationships e. For those types of relationships, men looked for women younger than the lower limits of the creepiness rule. For more committed and public relationships, men looked for women closer to their own age.

A mathematical theory says the perfect age to get married is 26 — here’s why

Many radioactive dating methods are based on minute additions of daughter products to a rock or mineral in which a considerable amount of daughter-type isotopes already exists. These isotopes did not come from radioactive decay in the system but rather formed during the original creation of the elements. In this case, it is a big advantage to present the data in a form in which the abundance of both the parent and daughter isotopes are given with respect to the abundance of the initial background daughter.

The incremental additions of the daughter type can then be viewed in proportion to the abundance of parent atoms. In mathematical terms this is achieved as follows. When some daughter atoms are initially present designated D 0 , the total number D is the sum of radiogenic and initial atoms, so that.

The basic technique involves modifying the Drake Equation, an acceptable age range of women for you to date is between and

The ‘Dating Rule’

This formula determines whether a year is a leap year. For standard quarters, you can determine which quarter a date falls in using this formula. This formula returns the number of the quarter that date falls in 1—4 by dividing the current month by three the number of months in each quarter and taking the ceiling. The formula for shifted quarters is similar, but shifts the month of the date by the number of months between January and the first quarter of the fiscal year.

To find the current week number, determine the days to date in the current year and divide that value by 7.

To have the highest chance of picking the very best suitor, you should date and reject the first 37 percent of your total group of lifetime suitors. (If you’re into math,​.

Love can be glorious, life-affirming and blissful. The issue isn’t just the parade of less-than-promising partners many daters confront. The problem is also figuring out what constitutes “good enough. In a world of some nine billion or so people, how can you know when the nice guy or gal you’re currently dating is the best you’re going to find? Are you settling down — i. For some lucky percentage of lovers, violins play, the heart beats fast, and the decision is blazingly obvious.

You simply know you’ve found “the one. Wait, what?

Subscriber Account active since. At that point in a selection process, you’ll have gathered enough information to make an informed decision, but you won’t have wasted too much time looking at more options than necessary. A common thought experiment to demonstrate this theory — developed by non-PC math guys in the s — is called “The Secretary Problem.

In the hypothetical scenario, you can only screen secretaries once. If you reject a candidate, you can’t go back and hire them later since they might have accepted another job. The question is: How deep into the pool of applicants do you go to maximize your chance of finding the best one?

Is the math formula to determine the appropriate age differential in dating a younger person reasonable? (Take your age, divide by two and add 7, any younger.

According to this rule, the age of the younger person should not be less than half the age of the older person plus seven years, so that for example no one older than 65 should be in a relationship with anyone younger than 39 and a half, no one older than 22 should be in a relationship with anyone younger than 18, and no one under 14 years of age should be in a relationship at all From another point of view, the chart can be interpreted as saying that there should not be an age disparity of as much as five years unless the younger person has an age of 19 or more, a ten-year disparity should exist only if the younger person has an age of 24 or more, and a twenty-year disparity should occur only if the younger person has an age of 34 or more.

And people only slightly older than 14 should only be involved with those almost exactly the same age as themselves. To read the chart, go to the position along the x-axis which corresponds to your age, and the green range between the black and red lines directly above that position corresponds to the range of your partner’s ages which is deemed acceptable by the rule. The area between the blue and red lines shows where you are the older partner in the half-age-plus-seven calculation, while the area between the black and blue lines shows where you are the younger partner.
