FOREIGN SCIENTISTS AND THEIR CONTRIBUTIONS
Aristotle
Student of Plato and a tutor to Alexander the Great, Aristotle was a genius Greek philosopher and scientist of the ancient age. Born on 384 BC, Aristotle was a biologist, a zoologist, ethicist, a political scientist and the master of rhetoric and logic. He also gave theories in physics and meta physics. Aristotle gained knowledge in different fields with his expansive mind and prodigious writings. However, only a fraction of his writings are preserved at present. Aristotle made collections to the plant and animal specimens and classified them according to their characteristics. He further gave theories on the philosophy of science. Aristotle also elaborated and estimated the size of earth which Plato assumed to be globe. Aristotle explained the chain of life through his study in flora and fauna where it turned from simple to more complex.
Archimedes of Syracuse
Regarded as the greatest mathematician ever, Archimedes developed profound and influential knowledge on mathematical physics and engineering that are widely used in machines as well as in constructions. Born on 287 BC, Archimedes is one of the finest scientist who broke through in both theories and practice. He introduced infinitesimals and laid the foundation for calculus. He gave descriptions on the first finite geometric progression, computed areas and volumes of sphere and parabolic segments. He also discovered the laws of lever, density, fluid equilibrium, buoyancy in different fields, statics and hydrostatics. He is regarded as the prophet to the formal science that was started in Ancient Greece.
Galileo Galilei
Born in Pisa, Italy in 1564, Galileo is called as the father of modern science because of his discoveries in astronomy and physics. He was sent to study medicine by his father, but he chose his career in science and mathematics and made the first telescope to observe stars and
