Dating Here of some of the well-tested methods of dating used in the study of early humans: Potassium-argon dating, Argon-argon dating, Carbon or Radiocarbon , and Uranium series. All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time. Thermo-luminescence, Optically stimulated luminescence, and Electron spin resonance. All of these methods measure the amount of electrons that get absorbed and trapped inside a rock or tooth over time. Since animal species change over time, the fauna can be arranged from younger to older.

Controversy[ edit ] Anthropologist Helen Fisher in What happens in the dating world can reflect larger currents within popular culture. For example, when the book The Rules appeared, it touched off media controversy about how men and women should relate to each other, with different positions taken by New York Times columnist Maureen Dowd  and British writer Kira Cochrane of The Guardian.

Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. All methods can be classified into two basic categories: Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.
These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials. This method includes carbon dating and thermoluminescence. The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope. Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope 14C.

Don’t leave drinks unattended; have an exit plan if things go badly; and ask a friend to call you on your cell phone an hour into the date to ask how it’s going. If you explain beautifully, a woman does not look to see whether you are handsome or not — but listens more, so you can win her heart.

New Telescope Observes Otherwise Invisible Terrestrial Entities with Intelligent Movement Read the article on one page A new report published in the latest edition of the American Journal of Modern Physics has revealed a startling finding — a newly developed telescope with concave lenses has observed, for the first time, entities in our terrestrial environment that are invisible to our eyes and to conventional Galileo telescopes with convex lenses.
Revolutionary New Santilli Telescope The discovery was made by Dr Ruggero Santilli, a highly-regarded expert in mathematics, cosmology, and physics, who has been nominated for Nobel Prizes in physics and chemistry. Dr Santilli developed a new type of telescope that was designed to observe antimatter-light. This form of light has a negative index of refraction, thus requiring concave lenses to focus it, rather than the traditional convex lenses used in conventional Galileo telescopes.
