Ten miles west of Cairo is the plateau of Giza. There, starkly dominating the skyline, stands the largest stone construction on the planet. Its structure shows a highly developed understanding of mathematics, astronomy, precision engineering, navigational theory, and geography. According to sci-fi author David McIlwaine, carbon 14 dating, the most reliable (though not infallible) scientific method of establishing age, places the construction at around 70,000 years BC, at least 60,000 years before man's discovery of these sciences. The Pyramid of Cheops is an almost total enigma. It is not a tomb, it does not appear to be a monument, yet it was built to endure the ravages of time. All conventional attempts to find a reason for the existence of the Great Pyramid - other than the simplistic one of a personal monument to Cheops - have failed conspicuously. A number of bizarre and fantastic alternative theories have been proposed and investigated. Some of the conclusions reached seem to bear more relation to science fiction than to science fact. They talk of strange and inexplicable forces, observed events that defy the laws of physics and molecular biology, and unknown energy fields that have an extraordinary effect on the human mind. Is this the stuff of what Egyptologists call "pyramidiocy"? Or is it something more? 1. Language: English. Narrator: Valentine Dyall, Blain Fairman, Carole Ann Ford, John Graham, Jacqueline Stanbury.

This work examines the ages of sambaquis through their deposits of malacological material. Its main objective is to implement a methodology to determine 14C in carbonate by its acid etching breakdown, releasing CO2 absorbed in Carbo-Sorb®, forming carbamate, determined by liquid scintillation. The methodology consisted of absorbing an average of 0.60 g of carbon in 10 mL of Carbo-Sorb® and 10 mL more of Permafluor® as scintillation cocktail. A Packard TR-LSC 3170 liquid scintillation spectrometer was used and an elapsed time of 1,000 minutes was employed. Using glass vials, the background radiation was an average of 3.99 ± 0.16 cpm, the detection limit was 3.77 x 10-4Bq/gC, and the age reached under these conditions was 22,400 BP. The sambaqui samples used for dating were collected in archaeological sites located in the embayment of the Guanabara Bay, in the Municipality of Guapimirim, State of Rio de Janeiro: Sambaquis from Sernambetiba, Imenezes, Rio das Pedrinhas, Amorins and Arapuan The sambaquis ages varied from 2,110 ± 250 BP to 3,690 ± 280 BP when using the CO2 absorption method.

Hot Carbon
45,90 CHF *
ggf. zzgl. Versand

There are few fields of science that carbon-14 has not touched. A radioactive isotope of carbon, it stands out for its unusually long half-life. Best known for its application to estimating the age of artifacts—carbon dating—carbon-14 helped reveal new chronologies of human civilization and geological time. Everything containing carbon, the basis of all life, could be placed in time according to the clock of radioactive decay, with research applications ranging from archeology to oceanography to climatology. In Hot Carbon, John F. Marra tells the untold story of this scientific revolution. He weaves together the workings of the many disciplines that employ carbon-14 with gripping tales of the individuals who pioneered its possibilities. He describes the concrete applications of carbon-14 to the study of all the stuff of life on earth, from climate science’s understanding of change over time to his own work on oceanic photosynthesis with microscopic phytoplankton. Marra’s engaging narrative encompasses nuclear testing, the peopling of the Americas, elephant poaching, and the flax plants used for the linen in the Shroud of Turin. Combining colorful narrative prose with accessible explanations of fundamental science, Hot Carbon is a thought-provoking exploration of how the power of carbon-14 informs our relationship to the past.

Beyond the Firmament

As debates within the Church over the scientific details of creation become more frequent, the 'experts' seem to grow more entrenched while the rest of us only become more confused. Somewhere between the endless arguments over distant starlight and Carbon-14 dating, calculating the mathematical improbabilities of things that already exist, and parsing ancient Hebrew and Greek, somebody needs to ask the simple question, 'If 3,500 years of scientific progress can't help modern Christians figure out Genesis, then how could the ancient Israelities possibly have understood it so well?' What secret did this newly liberated gaggle of Hebrew nomads take with them out of Egypt that holds the key to understanding God's telling of His own creation story? Beyond the Firmament challenges all creationist camps-whether Young-Earth, Old-Earth, or Theistic Evolutionist-to step outside of traditional paradigms and recognize how our modern, Western, post-Enlightenment scientific worldview actually blinds us from seeing the simple truth of Creation as it was originally intended, and how our failure to grasp the theological significance of the Biblical creation model puts science and faith on a collision course.
