Hi everyone, I tried many times, but still having a big trouble with one of the modelling questions regarding differential equations. Your help will be greatly appreciated. Known as isotopic dating, another substance with a longer half life is considered.

Archaeologists use the exponential, radioactive decay of carbon dating math 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.

More about dating math:
You might not think that finding your true love and mathematics have much in common, however increasingly you would be wrong. Just like the fact that more people are shopping online every year, more people are also dating online. This means that online dating is big business and consequently the sites that are best at helping people to meet their future partners are going to succeed in the market. This means that online dating sites need to have the best method for matching people and this is where the mathematics comes in. Assuming an online dating site has a large group of members, you need a way for people to be matched to others who they have a chance of being compatible with. Users are asked to input data into the site, typically answering questions about their likes, dislikes and hobbies. The search is then on to create the best algorithm which can use this data and match people successfully. Different sites have different methods for matching people, but the American dating site OKCupid particularly likes to boast about its use of mathematics in order to match people.

In this section we will explore the use of carbon dating to determine the age of fossil remains. Carbon is a key element in biologically important molecules. During the lifetime of an organism, carbon is brought into the cell from the environment in the form of either carbon dioxide or carbon-based food molecules such as glucose; then used to build biologically important molecules such as sugars, proteins, fats, and nucleic acids. These molecules are subsequently incorporated into the cells and tissues that make up living things. Therefore, organisms from a single-celled bacteria to the largest of the dinosaurs leave behind carbon-based remains. Carbon dating is based upon the decay of 14 C, a radioactive isotope of carbon with a relatively long half-life years. While 12 C is the most abundant carbon isotope, there is a close to constant ratio of 12 C to 14 C in the environment, and hence in the molecules, cells, and tissues of living organisms. This constant ratio is maintained until the death of an organism, when 14 C stops being replenished. At this point, the overall amount of 14 C in the organism begins to decay exponentially. Therefore, by knowing the amount of 14 C in fossil remains, you can determine how long ago an organism died by examining the departure of the observed 12 C to 14 C ratio from the expected ratio for a living organism.

The mathematics of dating is a series of formulae of increasing comlpexity, designed to describe various variables involved in dating and romance. The Standard Creepiness Rule states that if we define an individual's age as x , said individual should not date anyone under:. Now, this boring graph shows only the ages available. However does not take into account either the population of each age bracket something which would require individual research , nor the percentage of those who are single in each age bracket. It has been suggested however that graphing these equations will help boost your self-esteem, and generally give you something nice to put on your wall. A commonly noted problem however is that environmental factors often decrease the ability of individuals to find someone with mutual interest; so that despite the fact that the estimated dating pool only increases with age, the experienced dating pool seems to be much smaller. As such there are a variety of new variables to factor into any attempt at predictive equations, and thus we require a more detailed equation to handle this.
