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. Mid-century, the reason for the elevated age gap would’ve been economic. Women had little ability to earn income. Their husband was their access to social standing and economic stability. Obviously, an older man had more time to achieve a greater number of personal and financial goals. Relationship expert Rachel Russo also felt the rule had no basis in fact – but could see why it had endured.

U and Th are found on the extremely heavy end of the Periodic Table of Elements. Furthermore, the half life of the parent isotope is much longer than any of the intermediary daughter isotopes, thus fulfilling the requirements for secular equilibrium Section 2. We can therefore assume that the Pb is directly formed by the U, the Pb from the U and the Pb from the Th. The ingrowth equations for the three radiogenic Pb isotopes are given by: 5.

The corresponding age equations are: 5. This assumption cannot be made for other minerals, young ages, and high precision geochronology.

In a single decaying system, the age determined from the exponential decay law is directly related to its linear Maclaurin approximation. This relationship can be additively extended to several decaying systems resulting in the same daughter element, by using proportionality functions, thus allowing an explicit formulation of the age as a function of element concentrations. From the iteration data, the expressions of the two functions and the associated coefficients were determined by polynomial regression and mathematical programing on conveniently separated time and compositional intervals.

Additional time- and composition-dependent age corrections optimized by mathematical programming of the residuals lead to an accuracy of 0. The error propagation can be traced through all the operations defined by explicit formulas according to simple error propagation rules, finally allowing the calculation of the standard error of the result. The formulas and parameters derived can be used in a calculation spreadsheet. Tables, graphs and references.
