Archimedes

Archimedes’ research on machinery originated when he was studying in Alexandria. One day Archimedes was walking along the dry Nile River. Seeing that farmers struggled to lift water to irrigate their fields, after thinking about it, he invented a tool that used a spiral to rotate in the water pipe to suck up the water. Later generations called it the "Archimedes Spiral Water Lifter."

Egypt until modern times two thousand years later, there are still people using this instrument. This tool became the ancestor of later propellers.

Aristotle

Aristotle returned to Athens and established his own school there. The name of the academy (Lyceum) is named after the wolf-slayer (Lyceus) near the Temple of Apollo. During this period, Aristotle lectured and wrote many philosophical works. Aristotle had a habit of walking in the corridors and gardens while lecturing.

Because of this, the philosophy of the academy is called "the philosophy of leisure" or "the philosophy of wandering". Aristotle also wrote many works during this period, mainly about natural science and philosophy in nature and physics, and the language he used was much more obscure than Plato's "Dialogues".

Extended information:

Aristotle studied diligently throughout his life, and his academic research involved logic, rhetoric, physics, biology, education, psychology, He wrote a large number of works on politics, economics, aesthetics, natural history, etc. His works are ancient encyclopedias.

His thoughts have had a profound impact on mankind. He founded formal logic, enriched and developed various branches of philosophy, and made great contributions to science. He was the first person to demonstrate that the earth is spherical.

Archimedes made a huge contribution to the development of mathematics and physics, and made an indelible impact on social progress and human development. Even Newton and Einstein both learned from him. Drawing on wisdom and inspiration, he was "the ideal incarnation of theoretical genius and experimental genius in one person". Leonardo da Vinci and Galileo during the Renaissance used him as their role model.
