Two things: the somewhat random-looking picture above is from The Moon Is Blue, a film that’s the first known reference to the ‘dating rule’ discussed here. Secondly, I don’t make any judgement about the validity of the ‘dating rule’ – you might find it a useful rule of thumb or a ludicrous restriction; I find it a nice thing to do some algebra on. There is a so-called rule about dating: the youngest age you are supposed to date is half your age plus seven.

Why would we want to do this? Well, it means we can work out some other implications of the rule. For instance, you might want to know what the oldest age you could reasonably date would be. The rule doesn’t say anything about that, but it does also apply to the other person. How do we work that out? Well, we need to rearrange the equation.

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.

5) To use radiometric dating and the principles of determining relative age to show how ages of rocks and fossils can be narrowed even if they cannot be dated.

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.

The rule was so well-known by the s that even Malcolm X is quoted as being a staunch believer in half your age plus seven. Many decades later, the rule remains widespread. In the s, the online dating platform OkCupid also released data on age ranges that people entered when asked about their preferred partner.

Men, as it happens, roughly followed the half your age plus seven rule when it came to lowest age that they would consider in a partner … except for dudes in the mids, who were a little bit too interested in girls in the early 20s. Half your age plus seven has been used quite often over the years in dating and dating advice as an easy rule of thumb some like to follow to determine if it is a good idea—that is, appropriate or creepy—to hook up.

I’m Plagued by This Decades-Old Dating Equation

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.

At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues. When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death.

Love-hungry teenagers and archaeologists agree: dating is hard. But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes. Until this century, relative dating was the only technique for identifying the age of a truly ancient object.

By examining the object’s relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site. Though still heavily used, relative dating is now augmented by several modern dating techniques.

is used, or explore hundreds of other math, finance, fitness, and health calculators. One of the most well-known applications of half-life is carbon 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 Ask someone to take as many slips of paper as he pleases, and on each slip write a different positive number.

The numbers may range from small fractions of 1 to a number the size of a googol 1 followed by a hundred 0s or even larger. These slips are turned face down and shuffled over the top of a table. One at a time you turn the slips face up. The aim is to stop turning when you come to the number that you guess to be the largest of the series. You cannot go back and pick a previously turned slip. If you turn over all the slips, then of course you must pick the last one turned.

Back to dating. To demonstrate this Optimal Stopping Theory, the Science Vs team lays out an example: If a year-old would like to be married by age 35, she would therefore have 20 years of dating ahead of her. Or a year-old in a new dating scene might want to shift gears at

The Half Plus Seven Rule is an unwritten rule that asserts that it is creepy to date anyone who is younger than half your age plus 7 years. As the graph shows, there is a lower limit and an upper limit.

As age increases, the age range of potential non-creepy partners widens. At 26, the range of non-creepy partners is 18 years to year-olds. At 50, it is 54 years 32 to 86 years old. At age 14, you can only date people your own age.

The age of fossils can be determined using stratigraphy, biostratigraphy, and radiocarbon dating. Paleontology seeks to map out how life evolved across geologic time.
