But what about age? And what about age as it relates to older women involved with younger men? Actress Robin Wright, 47, is engaged to fellow actor Ben Foster, Pop star Shakira is involved with a man 10 years her junior. She is 13 years older than her mate. A recent article in Oprah magazine looked at a handful of real-life May-December romances, focusing mainly on those between older women and younger men.

Radiometric dating In , shortly after the discovery of radioactivity , the American chemist Bertram Boltwood suggested that lead is one of the disintegration products of uranium, in which case the older a uranium-bearing mineral the greater should be its proportional part of lead. Analyzing specimens whose relative geologic ages were known, Boltwood found that the ratio of lead to uranium did indeed increase with age.
After estimating the rate of this radioactive change, he calculated that the absolute ages of his specimens ranged from million to 2. Though his figures were too high by about 20 percent, their order of magnitude was enough to dispose of the short scale of geologic time proposed by Lord Kelvin. Versions of the modern mass spectrometer were invented in the early s and s, and during World War II the device was improved substantially to help in the development of the atomic bomb.
Soon after the war, Harold C. Wasserburg applied the mass spectrometer to the study of geochronology. This device separates the different isotopes of the same element and can measure the variations in these isotopic abundances to within one part in 10, By determining the amount of the parent and daughter isotopes present in a sample and by knowing their rate of radioactive decay each radioisotope has its own decay constant , the isotopic age of the sample can be calculated.
For dating minerals and rocks, investigators commonly use the following couplets of parent and daughter isotopes: The SHRIMP Sensitive High Resolution Ion Microprobe enables the accurate determination of the uranium-lead age of the mineral zircon, and this has revolutionized the understanding of the isotopic age of formation of zircon-bearing igneous granitic rocks.
Another technological development is the ICP-MS Inductively Coupled Plasma Mass Spectrometer , which is able to provide the isotopic age of the minerals zircon, titanite, rutile, and monazite.

These sorts of artifacts had previously been linked to the San culture, which was thought to have emerged around 20, years ago. Take our quiz Hints of culture Traces of civilization have been found going back nearly 80, years in Africa, but these fragments — bone tools, carved beads — vanish from the archaeological record by about 60, years ago. In fact, almost nothing is known about what happened in Southern Africa between 40, and 20, years ago, Villa and his colleagues wrote online today July 30 in the journal Proceedings of the National Academy of Sciences.
The researchers brought the latest in dating technology to bear on a site on the border of South Africa and Swaziland called Border Cave.

Whether it’s legs or a moustache, the youth of every generation can’t wait to do it. There really isn’t a specific age at which girls should start shaving their legs [source: It’s one of those tough questions that parents have to answer on an individual basis. Some girls may show an interest in shaving their legs as early as the fourth or fifth grade, but most girls don’t begin shaving until they reach middle school [source: Some parenting experts suggest that you try to reach a compromise with your daughter based on the average age that girls in your child’s school or neighborhood begin shaving, your personal values, and the age when you first started shaving [source: And most parenting groups agree that as long as your daughter is old enough to not hurt herself, you should let her shave her legs [source: For some girls, shaving their legs is less about growing up and more about issues of self-esteem [source: When girls reach puberty, the increase in hormones causes darker hair to grow on the legs, under the arms and in the pubic area, which can make girls self-conscious about their body hair [source:

Nicola McDougal Nicky has taught a variety of chemistry courses at college level. Nicky has a PhD in Physical Chemistry. Ever wondered how scientists know the age of old bones in an ancient site or how old a scrap of linen is? The technique used is called carbon dating, and in this lesson we will learn what this is and how it is used. A quiz will test how much we have learned. Definition of Carbon Dating Carbon dating, or radiocarbon dating, is a method used to date materials that once exchanged carbon dioxide with the atmosphere.
In other words, things that were living. In the late s, an American physical chemist named Willard Libby first developed a method to measure radioactivity of carbon , a radioactive isotope. Libby was awarded the Nobel Prize in chemistry for his work in

Evolution Before about it was widely thought that distinctively hominin fossils could be identified from 14 to 12 million years ago mya. However, during the s geneticists introduced the use of molecular clocks to calculate how long species had been separated from a common ancestor. The molecular clock concept is based on an assumed regularity in the accumulation of tiny changes in the genetic codes of humans and other organisms.
Use of this concept, together with a reanalysis of the fossil record, moved the estimated time of the evolutionary split between apes and human ancestors forward to as recently as about 5 mya. Since then the molecular data and a steady trickle of new hominin fossil finds have pushed the earliest putative hominin ancestry back in time somewhat, to perhaps 8—6 mya. Possible pathways in the evolution of the human lineage.
Announced in , this specimen is dated to the period between 7 and 6 mya. The distinctive mark of Hominini is generally taken to be upright land locomotion on two legs terrestrial bipedalism. The skull of S. The most remarkable aspect of this skull is the broadness and flatness of its face—something previously associated with much more recent hominins—in conjunction with a smaller, ape-sized braincase.
This specimen also has small canine teeth compared with those of apes, thus aligning it with the hominins in an important functional regard. Sahelanthropus, then, emphasizes an evolutionary pattern that seems to have been a characteristic of the tribe Hominini from the very start—a pattern that aligns it with what is observed in most other evolutionarily successful groups of mammals.

How much conflict do you experience between you? We seldom or never fight at all We fight all the time, always arguing or bickering at each other We argue a bit, but we manage to talk about it after and seem to get through it alright We don’t really fight, but there’s a lot of critical comments and negative remarks between us Question 3 of 17 3.
We seldom or never fight, so it’s not applicable to us If something gets too hard and we realize that fighting about it a lot is going nowhere we just ignore it or don’t bring it up any more After we’ve both cooled down, we’ll eventually talk about what happened.
