See the cal BP discussion for additional information about radiocarbon calibration.Tree-ring dating works because a tree grows larger--not just height but gains girth--in measurable rings each year in its lifetime.When Muhammad reported receiving a divine revelation, Ali was the first child to accept his message and first to convert to Islam at the age of 12, dedicating his life to the cause of Islam.In Muslim culture, Ali is respected for his courage, knowledge, belief, honesty to Islam, deep loyalty to Muhammad, equal treatment of all Muslims and generosity in forgiving his defeated enemies, and therefore is central to mystical traditions in Islam such as Sufism. He is revered by Sunni Muslims as the last of the four Rightly Guided Caliphs and as a foremost religious authority on the Qur'an and Fiqh (Islamic jurisprudence).Shi'a Muslims consider him the First Imam appointed by the Islamic prophet Muhammad and the first rightful caliph.
How large the cambium's cells grow in each year--measured as the width of each ring--is dependent on seasonal changes such as temperature and moisture availability.During the latter half of the nineteenth century, the scientific study of tree rings and the application of dendrochronology began.In 1859, the German-American Jacob Kuechler (1823–1893) used crossdating to examine oaks (Quercus stellata) in order to study the record of climate in western Texas.Environmental inputs into the cambium are primarily regional climatic variations, changes in temperature, aridity, and soil chemistry, which together are encoded as variations in the width of a particular ring, in the wood density or structure, and/or in the chemical composition of the cell walls.At its most basic, during dry years the cambium's cells are smaller and thus the layer is thinner than during wet years.
