For all other nuclides, the proportion of the original nuclide to its decay products changes in a predictable way as the original nuclide decays over time.This predictability allows the relative abundances of related nuclides to be used as a clock to measure the time from the incorporation of the original nuclides into a material to the present.Since 2007 he is director of the "Corpus Coranicum" project of the Berlin-Brandenburg Academy of Sciences and Humanities.Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.

A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide.

Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.

Sure, you’re not just having sex, you’re hanging out as well. With all these different levels of togetherness that we’ve invented, it’s no surprise that many times we’ll find ourselves with a person and not know how to introduce him or her to friends or family.”A lack of defining what is and is not happening has caused great confusion and emotional turmoil from singles in their 20s up to their 60s and 70s.… continue reading »
