1, the achievement in mathematics is Thales' Geometry, and Thales' epoch-making contribution in mathematics is to introduce him.
The idea of proposition proof. It broke the tradition that knowledge is based on experience, and knowledge began to rise from experience to theory, which is a great leap in the history of mathematics. Logical proof is introduced into mathematics, which endows mathematical propositions with strong persuasiveness and makes mathematics a strict scientific system, providing guidance for the later development of mathematics. At this time, the famous mathematician Euclid accomplished this great achievement. He wrote an encyclopedia of ancient Greek mathematics, which is also his masterpiece "Elements of Geometry". Only now has geometry been theorized and systematized for the first time. Geometry has gradually become an independent and complete discipline system, which has promoted the progress of human mathematics history.
2. Medicine is a great rational medical school represented by Hippocrates. It liberates medicine from religious superstition, conducts medical research and medical behavior with a truly scientific attitude, systematizes the medical knowledge of human beings in the past, puts forward new concepts and theories, and lays the foundation of European medicine.
3. In physics, Aristotle was the first person to make a comprehensive and systematic study of physical phenomena. He systematically explored and studied the time and space of object motion. He called all the changes of objects motion, and mainly studied the motion of the spatial position of objects. Secondly, Archimedes made outstanding contributions to mechanics. Not only did he make amazing contributions to mathematics and mechanics, but his scientific research method combining experiments with logical argumentation also had epoch-making significance.
4. The earliest code "Twelve Copper Tables Law", the first official code of the Roman Empire "Dior Doce Code" and "Justinian Code" were the first systematic and complete codes in Europe, and later, the Collection of Doctrine and the Ladder of Law were promulgated, collectively called "The Complete Book of Justinian Civil Law".
