Other well-known beliefs about leprechauns include the pot of gold that they are said to keep at the end of the rainbow, and their mischievous nature.

Whilst many are familiar with this general depiction of the leprechaun, there are other aspects of these Irish creatures that are less well-known.

Radiocarbon dating may only be used on organic materials.

Typically (6): The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left.

Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.

But new research shows that commonly accepted radiocarbon dating standards can miss the mark -- calling into question historical timelines.

It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.

In 1979, Desmond Clark said of the method “we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation” (3).

Though their initial calculations were slightly incorrect thanks to the contaminants of extensive nuclear testing of the age, scientists soon discovered the error and developed methods that were more accurate, including a date of calibration to 1950.Stone and metal cannot be dated but pottery may be dated through surviving residue such as food particles or paint that uses organic material (8).There are a number of ways to enter into a career in studying radiocarbon dating.These standard calibration curves assume that at any given time radiocarbon levels are similar and stable everywhere across each hemisphere. "We went looking to test the assumption behind the whole field of radiocarbon dating," Manning said."We know from atmospheric measurements over the last 50 years that radiocarbon levels vary through the year, and we also know that plants typically grow at different times in different parts of the Northern Hemisphere.Typically, a Master's Degree in chemistry is required because of the extensive lab work.
