What innovations were achievements of the Hellenistic Age? By the time of Archimedes, **the principles of the lever, the pulley, and the screw** had been formulated with scientific precision and were known as the law of floating bodies or specific gravity.

Eratosthenes' experiment (205 BC) **gave the first estimation of the Earth's radius simply by observing the shadow of a vertical stick at noon local solar time**.

The two schools of thought that dominated Hellenistic philosophy were **Stoicism, as introduced by Zeno of Citium, and the writings of Epikouros**. Stoicism, which was also greatly enriched and modified by Zeno's successors, notably Chrysippos (ca. 280–207 B.C.), divided philosophy into logic, physics, and ethics.

Archimedes discovered **the law of floating bodies or specific gravity** and formulated with scientific exactness the principles of the lever, the pulley, and the screw. Among his memorable inventions were the compound pulley, the tubular screw for pumping water, the screw propeller for ships, and the burning lens.

Which Hellenistic achievement had the greatest impact? **Geometry** because it helped in astronomy, architecture and still applies to us today.

Important developments include **the basic rules of geometry, the idea of a formal mathematical proof, and discoveries in number theory, mathematical analysis, and applied mathematics**. Ancient Greek mathematicians also came close to establishing integral calculus.

A mathematician, astronomer and geographer, he **devised the first system of latitude and longitude, and calculated the circumference of the earth to a remarkable degree of accuracy**. As a mathematician, his greatest legacy is the “Sieve of Eratosthenes” algorithm for identifying prime numbers.

Ancient Greek philosophers endeared to an understanding of nature and its natural order. They were drawn to similarities and differences of natural objects and natural patterns. From this they embraced mathematics **for its ability to describe the natural, especially as geometric patterns**.

The Greek philosopher **Aristotle** (384-322 B.C.) is credited as the first person to try and calculate the size of the Earth by determining its circumference (the length around the equator) He estimated this distance to be 400,000 stades (a stadia is a Greek measurement equaling about 600 feet).

The study of mathematics as a "demonstrative discipline" began in the 6th century BC with **the Pythagoreans**, who coined the term "mathematics" from the ancient Greek μάθημα (mathema), meaning "subject of instruction".

Trigonometry is a branch of mathematics that uses variables to determine heights and distances. There are **four** types of trigonometry used today, which include core, plane, spherical and analytic. Core trigonometry deals with the ratio between the sides of a right triangle and its angles.

Influence. Grothendieck is considered by many to be the greatest mathematician of the 20th century. In an obituary David Mumford and John Tate wrote: Although mathematics became more and more abstract and general throughout the 20th century, it was **Alexander Grothendieck** who was the greatest master of this trend.
