di Pisa. There he was taught by Dini and Bianchi‚ who quickly influenced Guido to undertake research in geometry. He presented his doctoral thesis Clifford’s Parallelism in Elliptic Spaces in 1900. Most young doctoral students take a few years to make themselves well know in their area. However‚ Guido was lucky for his teacher Bianchi was about to publish an important work on differential geometry. Bianchi discussed the results of Guido’s thesis in his treatise‚ which appeared in 1902. Guido remained

Bees know that the hexagon is superior to the square and the triangle because this shape will hold more honey and requires the least amount of energy and material. Bees have not studied tessellation theories‚ however some of their behavior patterns can be explained mathematically. A commonly asked question is‚ why do bees build hexagonal honeycombs? Through this unit I have seen the importance tessellations contribute to bees livelihood‚ as well as their success as insects. Bees not only use their

relationship between the legs and the hypotenuse of a right triangle."1 From this‚ he derived the Pythagorean Theorem. This contribution mainly influenced architecture and geometry today. Equally‚ Eratosthenes also influenced architecture and geometry. He developed a method of determining the circumference of the Earth by using geometry. Developed by Archimedes‚ the Archimedes Principle contributes greatly to the field of science. The principle states that "a body immersed in a fluid is buoyed up by a

lived in the time of the first Ptolemy; for Archimedes‚ who followed closely upon the first Ptolemy makes mention of Euclid‚ and further they say that Ptolemy once asked him if there were a shorted way to study geometry than the Elements‚ to which he replied that there was no royal road to geometry. He is therefore younger than Plato’s circle‚ but older than Eratosthenes and Archimedes; for these were contemporaries‚ as Eratosthenes somewhere says. In his aim he was a Platonist‚ being in sympathy with

Scope of mathematics This article will provide an overview of the NCTM process and content standards. Educators first studying the standards may feel overwhelmed with the amount of content addressed within each grade-level span. State frameworks that dictate standards for each grade level exacerbate this situation. However‚ a longitudinal view will show how the same topics are developed over several years in a spiral and interconnected pattern. For example‚ the
