100% Greek Philosophy, Science and Mathematics

The tradition of philosophy in Ancient Greece also added to the literary works. Greek learning has had a profound influence on Western and Middle Eastern civilisation. The works of Socrates, Plato, Aristotle, and other Greek philosophers profoundly influenced Classical thought, the Islamic Golden Age, and the Renaissance.
In medicine, doctors still refer to the Hippocratic oath, instituted by Hippocrates, who is also credited with laying the foundations of medicine as a science. Galen built on Hippocrates' theory of the four humours, and his writings became the foundation of medicine in Europe and the Middle East for centuries. The Greek physicians Herophilos and Paulus Aegineta were pioneers in the study of anatomy, while Pedanius Dioscorides wrote an extensive treatise on the practice of pharmacology.
Thales of Miletus is regarded by many as the father of science; he was the first Greek philosopher to seek to explain the physical world in terms of natural rather than supernatural causes. Pythagoras was a Greek mathematician who is known as the "father of numbers"; it is believed that he had the pioneering insight into the numerical ratios that determine the musical scale, and the Pythagorean theorem is commonly attributed to him. Diophantus of Alexandria is sometimes called the "father of algebra", and much of modern geometry is based on the work of Euclid. Eratosthenes was one of the first scientific geographers, calculating the circumference of the earth and making the first maps based on scientific principles. Hipparchus is considered to be the greatest astronomical observer of the ancient world, and was probably the first to develop an accurate method of predicting solar eclipses. Aristarchus was the first known astronomer to propose a heliocentric model of the solar system, though the geocentric model of Ptolemy was more commonly accepted until the sixteenth century. Ptolemy also contributed much to cartography and to the science of optics. Archimedes was the first to calculate the value of ð and the first to calculate a geometric series; he also was the first mathematical physicist, discovered the law of buoyancy, and invented the irrigation device known as Archimedes' screw.
Greek contributions to science continue in modern times. Mathematician Constantin Caratheodory worked in the fields of real analysis, the calculus of variations, and measure theory in the early 20th century. Professor John H. Argyris, a Greek mathematician and engineer, is credited with the invention of finite element analysis. Dr. Dimitris Nanopoulos is a noted theoretical physicist, having made significant contributions to the fields of particle physics and cosmology.
