The purpose of this chapter is to explain the process of radioactive decay and its relationship to the concept of half-life. Remember that a radionuclide represents an element with a particular combination of protons and neutrons nucleons in the nucleus of the atom. A radionuclide has an unstable combination of nucleons and emits radiation in the process of regaining stability. Reaching stability involves the process of radioactive decay. A decay, also known as a disintegration of a radioactive nuclide, entails a change from an unstable combination of neutrons and protons in the nucleus to a stable or more stable combination. The type of decay determines whether the ratio of neutrons to protons will increase or decrease to reach a more stable configuration. It also determines the type of radiation emitted. How do radioactive atoms decay?

Introduction The methods used by archaeologists to gather data can be applied to any time period, including the very recent past. One archaeologist in the U. Over the past years archaeologists have developed many effective methods and techniques for studying the past. Archaeologists also rely upon methods from other fields such as history, botany, geology, and soil science.

In this section of Methods of Gathering Data you will learn how archaeologists gather and analyze information by utilizing historical research techniques, field methods for data recovery, and laboratory analyses.

Radiocarbon dating (also referred to as carbon dating or carbon dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.. The method was developed in the late s by Willard Libby, who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon (

Determining Age and Examining Quality Over the last years, thousands of ancient Greek manuscripts have been found in countries all along the Mediterranean. The majority has come from Egypt. Age As stated before, the earlier the manuscript, the more valuable they are. If there are fewer copies between themselves and the originals, the potential for error is reduced. How can we be sure of the age of ancient writing? Can we actually find conclusive evidence that proves their age?

First, we might think that scientific tests, examining archaeological evidence regarding the physical nature of the papyrus might be in order. But, such tests have been proven to be inaccurate. While external factors can help, most manuscripts cannot be dated this way because of the ambiguous circumstances Comfort P. So, scholars are left with more subjective methods to date the ancient writings. The best way to date a manuscript is to examine the style of handwriting.

I avoided commitment for a long time because I was scared it would get boring if I stuck with one girl. It actually made me happy to think about just being with her. I had a sudden health condition where I had to spend a week in the hospital. It was out of nowhere. My girlfriend came every single day and was extremely supportive during my recovery. My then girlfriend ordered pizza for me and my roommate after I broke a date with her because I realized I needed to spend the time studying for the bar my roommate and I had both just graduated law school.

Plate Tectonics is a theory developed in the late s, to explain how the outer layers of the Earth move and deform. The theory has caused a revolution in the way we think about the Earth.

Burk We no longer feel the social pressure to confine sex to committed relationships. Sex is now an accepted recreational activity. We may have overcome our fear and shame about sex, but many of us still have issues regarding intimacy. If we experience more intimacy than we can handle, we will feel threatened; our safety checklist will be triggered. When we experience an orgasm, we reveal ourselves more completely and more honestly than at any other time.

We let our egos die for a moment, and we have the chance to experience a true connection with another person. We still equate sex with love, and love with commitment. And we equate love and commitment with vulnerability, responsibility, and the fear that our needs will not be met. What most of us crave, however, is not sex, but intimacy. The challenge is that the only model most of us have for expressing or experiencing intimacy is sex.

Intimacy requires trust, and trust takes time.

The ratio of carbon to carbon at the moment of death is the same as every other living thing, but the carbon decays and is not replaced. The carbon decays with its half-life of 5, years, while the amount of carbon remains constant in the sample. By looking at the ratio of carbon to carbon in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing fairly precisely.

A formula to calculate how old a sample is by carbon dating is: So, if you had a fossil that had 10 percent carbon compared to a living sample, then that fossil would be:

What is the IPRA? The Internet Piracy Review Agency (IPRA) is a proposed non-profit corporation by a coalition of companies including Bell Canada, Rogers, Cineplex, CBC, Corus, Toronto International Film Festival, and Cinémas Guzzo (collectively known as Fair Play Canada) to maintain a list of websites that have hosted or distributed pirated material and force all Internet Service Providers.

The genome of the MA-1 revealed that an Upper Palaeolithic population from this region admixed with ancestors of present-day East Asians, giving rise to the First American gene pool. Niobe Thompson A Danish-led international research team has mapped the hitherto oldest genome of an anatomically modern human: Surprisingly, the genetic material reveals that the boy was European, which means that a European culture reached all the way east to Lake Baikal.

In other words, Native Americans have partly European ancestry. This paints a new picture of Native Americans and at the same time solves a number of puzzles regarding the colonisation of America. The study has just been published in the journal Nature ; however, the results started to leak out about a month ago, after Willerslev spoke about the discovery at a conference in the US. Burial of the MA-1 Mal’ta child redrawn from Gerasimov , with photos of the plaque and swan from the burial and a representative Venus figurine from the excavation.

The colonisation of America has for decades been a hotly debated topic among researchers, with one of the big questions being who the first Americans were and where they came from. Very few skeletons from the right time and location Genetic analyses can help find the answers in two ways: Either by mapping the genetic traces of living people and reconstructing how our geographical distribution may have taken place.

Or by going directly to the genetic material from prehistoric remains to identify their relations. The first method has the advantage that it is easy to get hold of samples, but the analysis is more complex. The second method provides definitive answers, but very few skeletons from the right place and location are available.
