Early Mathematicians

Hello everyone.. Its been a long back i have updated my blog.. Almost i have forgot that am maintaining a blog too.. But i will try to update regularly from now on..

I have come up with a new topic which discusses about the history of great mathematicians.. I will keep posted about this for few weeks..

1. Thales
            
             Thales was an ancient philosopher who lived between 624 and 526 BC, in Miletus, a city in Ancient Greece that now forms a part of Turkey. Thales is regarded as the first true mathematician, because of the many important contributions he made to the field of mathematics, especially geometry.
             Thales used geometry to calculate the distance of a ship from the shore. He also figured out a way to measure the height of one of the Egyptian pyramids. He waited until the time of day when his own shadow was the same height that he was, and then, he measured the shadow of the pyramid, at the same time, to get its height.
              Thales was able to prove several interesting mathematical ideas. He proved that a circle is bisected-or cut into halves- by its diameter, and that the angles at the base of an isosceles triangle are equal.
              Thales has proved that if two straight lines cut one another, the opposite angles are equal and that if two triangles have two angles and a side in common, the triangles are identical.
