活动内容摘要:

Around 200 B.C. Greek geometer Apollonius of Perga in his work Tangencies stated the problem of drawing circles that are simultaneously tangent to three lines, or two lines and a circle, or two circles and a line, or three circles. As the years past, the topic attracted attention of Descartes, Princess Elizabeth of Bohemia, Leibniz, Nobel laureate Frederick Soddy, researches from AT&T lab working on an early GPS system, and connected number theory, geometry, and dynamics. Many captivating questions are still open.
