This book is the first documentation of ancient Thamizh (Tamil, as it’s known) Vallhuvam—viz, astronomy; calendars followed in other parts of the world; brief historical notes on Asia, wherever necessary; anthropology from creation of nature from the core; evolution of basic particles; and evolution of neutron star leading to the creation of stellar system. In addition are interlinked subjects, such as various stages of evolution of Earth from the core of sun; its age, as mentioned in Vallhuvam; and also evolution of the life system on Earth. The contents can be understood by all, and in particular, it is a useful reference book for students, scholars, and for researchers who are interested in Oriental studies.
