Whether it’s on a recipe, on a price tag, on a head count, or on a paycheck, numbers make us search for their meaning, and we trust that meaning to be dependable. We hope that number one means first place, and that having twins means there are two new babies rather than five. Numbers have inherent reliability. Sometimes, though, when sweat is pouring down your face, you might venture a guess and say, “Man, it must be degrees! The numbers in Gen 5 appear to be actual long ages of the antediluvian patriarchs. However, many have taken note of their atypically extensive size. Living over years?! This has caused many scholars and other curious people to plunge into finding out what these numbers actually mean. This paper is designed to present the various major issues regarding the interpretation of the numbers in Gen 5. Realistically, the issue must essentially include numerical, literary, rhetorical, cultural, historical, chronological, grammatical, geographical, and authorial issues besides many more, probably.

## Have scientists devised the formula for lasting love?

References Generic Radiometric Dating The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth. The equation is the one which describes radioactive decay: The variables in the equation are: Pnow – The quantity of the parent isotope that remains now.

This is measured directly.

How to use the Age Calculator Step 1: Select the month and day, and enter the 4-digit year of your date of birth. Or, if using this as an age difference calculator, enter the birth date of the oldest of the two persons on the first line. Select the month and day, and enter the 4-digit year of the date you would like to calculate your age as of that date. Or, if using this as an age difference calculator, enter the birth date of the youngest of the two persons on the second line.

If you would like to know on what date you will turn a certain age, enter that age in the field provided.

The formula can be applied to one week, one month or a year, but must be the same for each value of the formula. The formula for a manufacturer includes raw goods and unfinished product in inventory. The formula for a manufacturer includes raw goods and unfinished product in inventory.

This equation allows us to figure out how many radioactive atoms are left after any amount of time. There are many general forms of the equation that deal with chains of nuclides, but here we only worry about the basics. Number of atoms at any given time We start by noting that the speed of radioactive decays occurring in a sample is proportional to the number of radioactive atoms in the sample. Atoms that decay faster have larger decay constants, and so on.

Now that we know the rate at which our sample is decaying, we can integrate this rate to figure out the total number of atoms that have decayed at any given time. Here we go, step-by-step: Relating the half-life to the decay constant Excellent. The final equation there is the well-known radioactive decay equation. The blue curve represents a nuclide that has a year half-life. Compare this with the green curve, which represents a nuclide with a year half-life.

Decays of several example nuclides with different half-lives from 50 to years. The Python code to generate this image is available here. These may be useful for radiogenic dating of objects like the Earth , understanding nuclear waste behavior, etc.

## Homework Help: Radiometric Dating Equation Clarification

An important component of the Systemic Initiatives was the aggressive distribution of NCTM aligned curricula for classroom use. The NCTM Standards were vague as to mathematical content, but specific in its support of constructivist pedagogy, the criterion that mattered most to the NSF. It should be noted that the Systemic Initiatives sometimes promoted curricula not on the list above, such as College Preparatory Mathematics, a high school program, and MathLand, a K-6 curriculum.

For example, Methuselah at the age of years would instead be only months, or now, 81 years by the new figuring”a more reasonable age in today’s standards. Using this definition, though, places the numbers into even more severe problems than at the outset. 6 This issue loses weight, too, just by the context of Gen 6.

Roman poet Lucretius, intellectual heir to the Greek atomists, believed its formation must have been relatively recent, given that there were no records going back beyond the Trojan War. The Talmudic rabbis, Martin Luther and others used the biblical account to extrapolate back from known history and came up with rather similar estimates for when the earth came into being.

Within decades observation began overtaking such thinking. In the s Nicolas Steno formulated our modern concepts of deposition of horizontal strata. He inferred that where the layers are not horizontal, they must have been tilted since their deposition and noted that different strata contain different kinds of fossil. This position came to be known as uniformitarianism, but within it we must distinguish between uniformity of natural law which nearly all of us would accept and the increasingly questionable assumptions of uniformity of process, uniformity of rate and uniformity of outcome.

That is the background to the intellectual drama being played out in this series of papers. It is a drama consisting of a prologue and three acts, complex characters, and no clear heroes or villains. We, of course, know the final outcome, but we should not let that influence our appreciation of the story as it unfolds. Even less should we let that knowledge influence our judgment of the players, acting as they did in their own time, constrained by the concepts and data then available.

One outstanding feature of this drama is the role played by those who themselves were not, or not exclusively, geologists. Most notable is William Thomson, ennobled to become Lord Kelvin in , whose theories make up an entire section of this collection.

## What’s the math equation to figure out if someone is too young for you?

Student View Task Carbon 14 is a common form of carbon which decays over time. The half-life of Carbon 14, that is the amount of time it takes for half of the Carbon 14 to decay, is approximately years. If there is currently one microgram of Carbon 14 remaining in the preserved plant, approximately when did the plant die? IM Commentary The task requires the student to use logarithms to solve an exponential equation in the realistic context of carbon dating, important in archaeology and geology, among other places.

Note that the purpose of this task is algebraic in nature — closely related tasks exist which approach similar problems from numerical or graphical stances.

If the epact is 27 xxvii , an ecclesiastical new moon falls on every date labeled xxvii. The ecclesiastical full moon falls 13 days later. From the table above, this gives a new moon on 4 March and 3 April, and so a full moon on 17 March and 16 April. Then Easter Day is the first Sunday after the first ecclesiastical full moon on or after 21 March. This definition uses “on or after 21 March” to avoid ambiguity with historic meaning of the word “after”. In modern language, this phrase simply means “after 20 March”.

The definition of “on or after 21 March” is frequently incorrectly abbreviated to “after 21 March” in published and web-based articles, resulting in incorrect Easter dates. In the example, this paschal full moon is on 16 April. If the dominical letter is E, then Easter day is on 20 April. The label “25” as distinct from “xxv” is used as follows:

This was as true of their mathematics as anything else, and they adopted elements of mathematics from both the Babylonians and the Egyptians. But they soon started to make important contributions in their own right and, for the first time, we can acknowledge contributions by individuals. By the Hellenistic period , the Greeks had presided over one of the most dramatic and important revolutions in mathematical thought of all time.

It was a base 10 system similar to the earlier Egyptian one and even more similar to the later Roman system , with symbols for 1, 5, 10, 50, , and 1, repeated as many times needed to represent the desired number. Addition was done by totalling separately the symbols 1s, 10s, s, etc in the numbers to be added, and multiplication was a laborious process based on successive doublings division was based on the inverse of this process.

Thales’ Intercept Theorem But most of Greek mathematics was based on geometry.

Carbon-dating evaluates the ratio of radioactive carbon to stable carbon Given the amount of carbon- 12 contained a measured sample cut from the document, there would have been about × 10 –12 grams of carbon- 14 in the sample when the parchment was new, assuming the proposed age .

Mar 30, Suzanne Hadley Gosselin For the sake of this article, we’ll define an age difference as five years or more. I felt the panic rising in my chest. I’d just done the math. After spending a few days trying to adjust to the fact that the handsome co-leader of my small group was seven years my junior, I had just realized that he was actually eight years younger! I don’t know why this one year made such a difference to me. I guess it was because I’d heard two or three stories of the woman being seven years older, so I’d sort of decided that was the outer limit of age difference acceptability.

But the fact was, I was 30, and he was And I would hit 31 a month before his next birthday. Feeling defeated, I sat at the small wooden table in Starbucks, where I was meeting Kevin for the first time since my startling discovery. My mind was reeling. This will never happen, I thought. What was I thinking? Eight years is just too big of a difference.

Then he approached the table with the same winning smile … and I thought, or is it?

## 4 Things to Consider When Dating With an Age Difference

Carbon Dating Carbon dating to determine the age of fossil remains 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 14C, a radioactive isotope of carbon with a relatively long half-life years.

A represents the amount at a given time t. Ao represents the initial amount of the growing entity. If the information for time is given in dates, you need to convert it to how much time has past since the initial time. You can use this formula to find any of its variables, depending on the information given and what is being asked in a problem.

For example, you may be given the values for Ao and t and you need to find the amount A after the given time. Or, you may be given the final amount A and the initial amount Ao and you need to find the time t.

Dinosaurs disappeared about 65 million years ago. That corn cob found in an ancient Native American fire pit is 1, years old. How do scientists actually know these ages? Geologic age dating—assigning an age to materials—is an entire discipline of its own. In a way this field, called geochronology, is some of the purest detective work earth scientists do.

There are two basic approaches: Here is an easy-to understand analogy for your students: Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old. To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones.

This is called the Rule of Superposition.
