Radiocarbon dating is one such type of radiometric dating.Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence.The method of reading the order is called stratigraphy (layers of rock are called strata).Relative dating does not provide actual numerical dates for the rocks.One of the earliest was the Padua botanical garden.These gardens facilitated the academic study of plants.This matching process is called correlation, which has been an important process in constructing geological timescales.

A botanist or plant scientist is a scientist who specialises in this field.When an atom varies in the number of neutrons, the variation is called an isotope. During radioactivity, the unstable isotope breaks down and changes into a different substance.A new, more stable isotope, called the decay or daughter product, takes its place.Efforts to catalogue and describe their collections were the beginnings of plant taxonomy, and led in 1753 to the binomial system of Carl Linnaeus that remains in use to this day.

In the 19th and 20th centuries, new techniques were developed for the study of plants, including methods of optical microscopy and live cell imaging, electron microscopy, analysis of chromosome number, plant chemistry and the structure and function of enzymes and other proteins.Within the nucleus, we find neutrons and protons; but for now, let's just focus on the neutrons.
