Ice-sheet dynamics Sampling the surface of Taku Glacier in Alaska. There is increasingly dense firn between surface snow and blue glacier ice. An ice core is a vertical column through a glacier, sampling the layers that formed through an annual cycle of snowfall and melt. At Summit Camp in Greenland, the depth is 77 m and the ice is years old; at Dome C in Antarctica the depth is 95 m and the age years. The bubbles disappear and the ice becomes more transparent. Ice is lost at the edges of the glacier to icebergs , or to summer melting, and the overall shape of the glacier does not change much with time.

Ancient jades, bronzes, paintings, calligraphies—previously the domain of a few academics and connoisseurs—captured the imagination of collectors worldwide. Chinese jades are a particularly fascinating area of Chinese decorative arts.

Potential of abundant, environmentally harmless energy technology , which already exists My strategy for manifesting that energy event for humanity’s and the planet’s benefit. I w as born in In that same year, I had my cultural and mystical awakenings. During my second year of college, I had my first existential crisis and a paranormal event changed my studies from science to business.

I s till held my energy dreams, however, and in , eight years after that first paranormal event, I had a second one that suddenly caused me to move up the coast from Los Angeles to Seattle, where I landed in the middle of what is arguably the greatest attempt yet made to bring alternative energy to the American marketplace. That effort was killed by the local electric industry , which saw our technology as a threat to its revenues and profits, and my wild ride began.

The owner of the Seattle business left the state to rebuild his effort. I followed him to Boston and soon became his partner. M y partner’s experiences in Seattle radicalized him.

The thermoluminescence technique is the only physical means of determining the absolute age of pottery presently available. It is an absolute dating method, and does not depend on comparison with similar objects as does obsidian hydration dating, for example. Most mineral materials, including the constituents of pottery, have the property of thermoluminescence TL , where part of the energy from radioactive decay in and around the mineral is stored in the form of trapped electrons and later released as light upon strong heating as the electrons are detrapped and combine with lattice ions.

How did Libby test his method and find out if it worked correctly? Libby tested the new radiocarbon method on carbon samples from prehistoric Egypt whose age was known. A sample of acacia wood from the tomb of the pharoah Zoser was dated for example. Zoser lived during the 3rd Dynasty in Egypt BC. The results they obtained indicated this was the case. Many other radiocarbon dates were conducted on samples of wood of known age. Again, the results were good. In , Libby and his team published their results.

By the early s there were 8 new radiocarbon laboratories, and by the end of the decade more than How much sample material do you need to date using radiocarbon? A new way of radiocarbon dating was developed in the late s called “AMS Radiocarbon dating”.

I have been waging a war on arrogant certitude in science, all my long life, and am fortunate to have lived long enough to see the cultural biases and politically correct conventional wisdom regularly blown out of the water! RobertPPruitt It says they had bigger brains than Neanderthals. Jebel Irhoud hominins should be judged against an indigene African braincase biometric baseline or Bloods and Crips vs. Then again, archeology is also subject to revision, so maybe at various times different groups of humans began the first steps towards what we would recognize as civilization, only to suffer catastrophic setbacks.

Always be prepared to accept that science involves revision and refinement, and sometimes complete paradigm shifts altogether.

The Limits of TL Thermoluminescence dating of a ceramic requires two steps. The first consists of gauging the accumulated radiation or ‘archaeological dose’ absorbed by crystals in the ceramic since its firing. Buried terra cottas are irradiated by radioelements in the objects themselves and by those in the soil in which they are buried. To measure accumulated radiation, one tracks the thermoluminescent properties of the crystals — when heated, they release stored radioactive energy in the form of light.

The Hou Hanshu states: They resemble the people of the Middle Kingdom and that is why this kingdom is called Da Qin. They say they originally came from China, but left it. Graf , pp. For the most part, such mythological elements are so strikingly evident that they represent only a minimal problem. According to the Hou-Han shu, the Roman Empire was so named precisely because its people and civilization were comparable to those of China.

Yu believes Daxia [dat-hea] stands for the Tochari pp. It is just possible that Da Qin represents some similar process though, if this is the case, it is difficult to imagine what name it was originally intended to represent. The latter identification led Pelliot to propose that it transcribed the name of Alexandria in Egypt, of which more will be said below. What is apparently missing is anything to correspond to Old Persian initial w-, represented in Greek by the syllable Hy- the letter upsilon with spiritus asper.

TL-tests to authenticate old pottery A TL-test could be made on all kinds of fired pottery such as earthenware, stoneware as well as true porcelain. Even antique bronzes could be dated this way provided they are made with a clay core which is sometimes the case. TL is short for “Thermoluminescence test” which is scientific method of calculating the age of antiques.

Luminescence Dating The Luminescence Dating Laboratory at the Research Laboratory for Archaeology and the History of Art, University of Oxford, has been actively involved in the development and application of luminescence dating for more than 50 years. The Laboratory has considerable experience in the dating of sediments and pottery and offers a service for luminescence dating of archaeological, environmental and Quaternary geological contexts.

This includes optically stimulated luminescence OSL dating of sediments as well ceramics pottery, brick, tile, etc… , and burnt stones. Applications of Luminescence Dating Luminescence dating is particularly appropriate when radiocarbon dating is not possible either where no suitable material is available or for ages beyond the radiocarbon age limit or for applications affected by radiocarbon plateau effects e.

The particular advantage of luminescence dating is that the method provides a date for the archaeological artefact or deposit itself, rather than for organic material in assumed association. In the case of OSL sediment dating, suitable material sand or silt-sized grains of quartz and feldspar is usually available ubiquitously throughout the site. Age range and precision The age range for pottery and other ceramics covers the entire period in which these materials have been produced.

The typical range for burnt stone or sediment is from about to , years. We are also able to conduct sample collection outside of the UK if the client is willing to cover additional transport, accommodation and subsistence costs. Postgraduate students registered for a degree course within a UK university which does not house a luminescence laboratory may be eligible to apply for an award through a joint scheme set up with the Quaternary Research Association http: Likewise, projects central to the Laboratory’s research interests may be carried out at a reduced charge.

The typical turn-round time for providing a date is circa months, although, rapid dating circa weeks or sometimes less, depending on machine time and sample type using our fast track service can be undertaken.

Vedas and Motion of Planets The core foundation of Hindu belief is that Vedas contain source of all knowledge — physical or metaphysical. However in last odd years, this belief has come under scrutiny due to the advances that modern science claims to make. However in modern era of religious marketing, another group has come up which would go to any length to discover scientific errors in Vedas. This is the group which would want million Hindus to lose faith in Vedas and their religion and embrace what they believe is the final message of God.

The most common method for dating artifacts and biological materials is the carbon (14 C) r, it poses a serious problem for deep-time advocates because it cannot be used for dating anything much older than 50, years.

Should people lay off social psychologists with unreplicable ideas? After naming a number of psychologists whose work has come under criticism for overhyped claims and underpowered samples, she decries the level of public criticism that these scientists have received: Good science requires a spirit of collaboration, not domination. The debate in social psychology involves some essential criticism of past scientific practice, but revolutions can also lead to a bandwagon effect, in which bullies pile on and bystanders fearfully turn a blind eye.

There is a better way forward: Sabeti contrasts the current situation in social psychology with genomics. According to Sabeti, human genetics did not take the path of strong public criticism of underpowered studies, or of vilification of the researchers trying to find gene-trait associations with too little data.

Bosna i Hercegovina From the book “Politics of Genocide” author dr. Herman During the civil wars that accompanied the dismantling of the Federal Republic of Yugoslavia in the s, the United States, Germany, NATO, and the European Union EU all sided with the national groups seeking to break away from the unified federal state, and opposed the national group that held out for the longest time to preserve it, the Serbs; this placed the Western bloc solidly behind the Croats and Slovenes, then the Bosnian Muslims, and finally the Kosovo Albanians.

Because the wars were supported and even carried out by the NATO powers, and there was significant ethnic cleansing and ethnic killings, it goes almost without saying that not only “ethnic cleansing” but also the words “massacre” and “genocide” were quickly applied to Serb operations. The remarkable inflation of claims of Serb evil and violence and playing down of NATO clients’ violence , with fabricated “concentration camps, ” “rape camps,” and similar Nazi- and Auschwitz-like analogies, caused the onetime head of the U.

Popular perceptions pertaining to the Bosnian Muslim government have been forged by a prolific propaganda machine. A strange combination of three major spin doctors, including public relations PR firms in the employ of the Bosniacs, media pundits, and sympathetic elements of the US State Department, have managed to manipulate illusions to further Muslim goals.

Yes I am referring to Islamic and Christian evangelists. This is because a bulk of Islamic evangelists believe that Jesus will come again towards end of the world after which they would reach Paradise forever. I do not know the original source of this superstition, but this remains a primary motivator for most Islamic evangelists today. The typical pattern would be english translation of some mantra followed by a Veda Mantra reference.

But for layman, these create a lot of confusion and doubt over relevance of Vedas. While I would shy away from thrusting my personal faith on Vedas, I would like to provide some excerpts from Vedas that provide clues to deep scientific concepts hidden within them. Unfortunately, due to thousand years of slavery, burning of our universities and libraries by barbarians and then demands for tackling issues of survival first, there remains a lot of work to be done to rediscover the Vedic sciences.

However, sufficient clues exist to justify why this rediscovery would be worthwhile.

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.

Luminescence dating (including thermoluminescence and optically stimulated luminescence) is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past.

Different materials vary considerably in their suitability for the technique, depending on several factors. Subsequent irradiation, for example if an x-ray is taken, can affect accuracy, as will the “annual dose” of radiation a buried object has received from the surrounding soil. Where there is a dip a so-called “electron trap” , a free electron may be attracted and trapped.

The flux of ionizing radiation—both from cosmic radiation and from natural radioactivity—excites electrons from atoms in the crystal lattice into the conduction band where they can move freely. Often the gamma radiation field at the position of the sample material is measured, or it may be calculated from the alpha radioactivity and potassium content of the sample environment, and the cosmic ray dose is added in.

Once all components of the radiation field are determined, the accumulated dose from the thermoluminescence measurements is divided by the dose accumulating each year, to obtain the years since the zeroing event.
