In the sciences, it is important to distinguish between precision and accuracy.If we use the analogue of a clock we can investigate this further.Drilling a vertical hole through this ice involves a serious effort involving many scientists and technicians, and usually involves a static field camp for a prolonged period of time. Shallow ice cores (100-200 m long) are easier to collect and can cover up to a few hundred years of accumulation, depending on accumulation rates. And many of them "were amazingly good experimentalists,” says Lawrence Principe, a chemist and science historian at Johns Hopkins University.“Any modern professor of chemistry today would be more than happy to hire some of these guys as lab techs.” The alchemists counted among their number Irish-born scientist Robert Boyle, credited as one of the founders of modern chemistry; pioneering Swiss-born physician Paracelsus; and English physicist Isaac Newton.Alchemists have often been dismissed as pseudoscientific charlatans but in many ways they paved the way for modern chemistry and medicine.The alchemists of the 16th and 17th centuries developed new experimental techniques, medicines and other chemical concoctions, such as pigments.

The supposedly dense, waxy, red material was said to enable the process that has become synonymous with alchemy— the metamorphosis, or transmutation, of base metals such as lead into gold. Through analysis of ice cores, scientists learn about glacial-interglacial cycles, changing atmospheric carbon dioxide levels, and climate stability over the last 10,000 years. This picture shows a traversing field camp from December 2010. From top to bottom: * Levels of carbon dioxide (CO2). High rates of snow accumulation provide excellent time resolution, and bubbles in the ice core preserve actual samples of the world’s ancient atmosphere[6]. Your wrist watch may measure time with a precision of one second.

A stop watch may time your race with a precision of one hundredth of a second.

In this first chart, we have a radioactive substance with a half life of 5 years.
