This rules states that by dividing your own age by two and then adding seven you can find the socially-acceptable minimum age of anyone you want to date. Take your age, subtract 7, and double it. So for a year old, the upper age limit would be 34 i. With some quick math, the rule provides a minimum and maximum partner age based on your actual age that, if you choose to follow it, you can use to guide your dating decisions. But how legitimate is this rule? Does it match our scientific understanding of age-related preferences for dating? Does it always apply? How well does the rule reflect scientific evidence for age preferences?

Does Age Bring Wisdom

Such concepts would have been part of everyday life in hunter-gatherer societies. The idea of the “number” concept evolving gradually over time is supported by the existence of languages which preserve the distinction between “one”, “two”, and “many”, but not of numbers larger than two. For example, paleontologists have discovered in a cave in South Africa , ochre rocks about 70, years old, adorned with scratched geometric patterns.

Moreover, hunters and herders employed the concepts of one, two, and many, as well as the idea of none or zero, when considering herds of animals.

Oct 01,  · This is the British International School Phuket’s IB maths exploration (IA) page. This list is for SL and HL students – if you are doing a Maths Studies IA then go to this page instead. The authors of the latest Pearson Mathematics SL and HL books have come up with ideas for students doing their maths explorations. I have supplemented these with some more possible areas for investigation.

Age of the Universe How old is the world? Ancient commentators propose that the world may be simultaneously young and old. Gerald Schroeder One of the most obvious perceived contradictions between Torah and science is the age of the universe.

Mathematics, the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. It deals with logical reasoning and quantitative calculation, and its development has involved an increasing degree of .

The underlying question is why Euclid did not use this proof, but invented another. One conjecture is that the proof by similar triangles involved a theory of proportions, a topic not discussed until later in the Elements, and that the theory of proportions needed further development at that time. The large square is divided into a left and right rectangle. A triangle is constructed that has half the area of the left rectangle. Then another triangle is constructed that has half the area of the square on the left-most side.

These two triangles are shown to be congruent , proving this square has the same area as the left rectangle. This argument is followed by a similar version for the right rectangle and the remaining square. Putting the two rectangles together to reform the square on the hypotenuse, its area is the same as the sum of the area of the other two squares.

Let A, B, C be the vertices of a right triangle, with a right angle at A. Drop a perpendicular from A to the side opposite the hypotenuse in the square on the hypotenuse.

What Vedas say about the age of the Universe

Probability and its engineering uses by Thornton C Fry, Radiometric dating Suppose you want to know how long ago something happened. For example, a forensic analyst might want to know how long ago a dead person ate breakfast. Or an astrophysicist might want to know the age of the solar system. Or an archeologist might want to now how old the dead-sea scrolls are, or how long ago did we evolve a desire for art.

Use the age equation below and your knowledge of radiometric age dating to answer the following questions The age equation Where t age of the rock or mineral specimen D = number of daughter product atoms P number of parent atoms A = appropriate decay constant In2 1/2 4) Use the equations above to determine the ages of rock units G & D from the.

Pollution resolution If I replace my old diesel car with a less polluting new petrol one, how long will it take for the reduced pollution of the new car to outweigh the increased pollution caused by the manufacture of the new car and the disposal of the old, assuming average usage? It seems such a waste of energy. I read that a supermarket won an award for its two-year-matured puddings. So, what happens over two years to bring out the flavour?

Where I live, I use five different bins and the collections are fortnightly. Unlike many people I observe, I squash things like aluminium cans and plastic milk bottles.

Explaining the “whys” of mathematics Engaging students: Half-life In my capstone class for future secondary math teachers, I ask my students to come up with ideas for engaging their students with different topics in the secondary mathematics curriculum. In other words, the point of the assignment was not to devise a full-blown lesson plan on this topic. Instead, I asked my students to think about three different ways of getting their students interested in the topic in the first place.

For example, two tablets found at in , dating from BC, give lists of the squares of numbers up to 59 and the cubes of numbers up to The Babylonians used the lists of squares together with the certain formulas to assist in multiplication.

The Nora Ephron Theorem of Soulmates: Through this theorem, x will spend her lifetime alone because y is an imaginary expectation of perfection and absolute satisfaction embodied in a human as demonstrated by the CW network and it will never exist, let alone come to New York to save x from herself. In this case, 24x is divided by the number of males that x has encountered within the age span, keeping in mind the exception to this rule, The Billy Loomis factor.

Following the logical schematic exclusions of social interaction with males who plot to murder x in a Freudian revenge model like Billy Loomis in Scream , we must subtract the sum total of the Billy Loomis Factor from overall male-interactions, i. When this is complete, we can divide using the new value of males. Cannot divide by zero. This equation can be graphed thusly: As evidenced by the graph, x is approaching her limit.

Radioactive Carbon Dating

The equation[ edit ] Cumming defines the equation [1] as is the frequency of the hydrogen fine transition line — the frequency emitted by a neutral hydrogen atom when the spin of the electron in the ground state flips from parallel to the spin of the proton to antiparallel to the spin of the proton. It is equal to Actually, it equals It is defined to be either 0.

Errors in the equation[ edit ] There are several errors in Cumming’s equation.

Posted on July 21, by The Physicist Physicist: When things die they stop getting new carbon and the carbon they have is free to radioactively decay without getting replaced. Carbon has a half-life of about 5, years, so if you find a body with half the carbon of a living body, then that somebody would have been pretty impressed by bronze.

Of course none of that helps when it comes to pottery and tools except wooden tools. Generally speaking, archaeologists make the assumption that if the grains in and around of a clay pot are, say, 8, years old, then the pot itself is roughly the same age. If you had an ancient amphora sitting around, would you use it for fresh strawberry preserves? And before you answer: A life spent potentially confusing future archaeologists is a life well spent.

There are many different kinds of radiometric dating that are used to date things that are non-organic which is part of how we determine the age of the Earth.

Planning Process Campus Announcement February 5, at If your daughter is recruited by Stanford, she should go. If she desires to go to ASU, she should go, and not wait for someone else to ask. She determines her future, not college recruiters. And btw, we are all ELL in this country. Nothing special about it.

11) Carbon Dating: the formula (t in years) is used to estimate the age of organic material. The ratio of carbon 14 to carbon 12 in a piece of charcoal found at an archaeological dig is R = 1/10

This is great stuff on Prenups. I have no intention of going into Family Law, but I think maybe we can combine efforts and create an article on Prenups. Not legal advice, of course, but a crash-course on Prenups. I already started on the article for RoK on prenups, but you seem knowledgeable on the topic and maybe we can combine efforts?
