I spent 25 minutes reading the biography on Thales. I made sure to read and understand what all he has done. Since I didn't know of him I took the time to read up on him and his work on mathematics. This site was about a man who is said to have some influence on mathematics, mainly in geometry. Because of the time he was living in, there isn't much work or writings he did on display. This time period many men have claimed to do have idea's but no real proof. I did find it interesting that some famous mathematicians did acknowledge his idea's so he was a starting factor to mathematics. I think the site used the information that it had and did show that Thales was a well respected mathematician. He did bring Geometry to the Greeks and is said to be one of the first Philosophers before Socrates. With the lack of information on Thales, the site did bring good examples of his work. I think this could only be used to a biography of Thales life and not necessarly for teaching of him and his work. Because there isn't a lot of documentation it is hard to follow his work. But they did talk about his geometry and his way of measuring pyraminds and shadows. They also talked of his ideas of the world, how Earth was flat and was on water. Although his ideas are well dated, he did have the knowledge to explain things and give reasons why things happen. I think this site was very easy to use, although like I said before, it is good for a history update on Thales, but to learn exactly what he did is a little tougher. Although there wasn't a lot from him written down, he was praised as a fine mathematician.
