Heraclituswas a Greek philosopher who lived during the period of 6th Century B.C. He was able to calculate the diameter of the Sun and concluded it to be one third of a meter. Although he didn’t succeed his contributions had been able to inculcate the development of astronomy. Th precise data about the Sun says that the diameter is 1.4 Million Km (870,000 Miles) as per the modern technology-abled data.
However this is what wikipedia has to say about this ancient astronomer.
{ Heraclitus is known for his doctrine of change being central to the universe, and that the Logos is the fundamental order of all. Today, he is famous for his influence on Friedrich Nietzsche by the idea of every moment being its own universe; summarized in his famous quote, “You could not step twice into the same river; for other waters are ever flowing on to you” }
Thus I dedicate the IYA 2009 Astronomy Sri Lanka blog today for the ancient astronomer Heraclitus in honor of his outstanding contribution towards astronomy.
