A Turing machine that is able to simulate any other Turing machine is called a universal Turing machine (UTM, or simply a universal machine). Another mathematical formalism, lambda calculus, with a similar "universal" nature was introduced by Alonzo Church. Church's work intertwined with Turing's to form the basis for the Church–Turing thesis.
This evidence that the Antikythera mechanism was not unique adds support to the idea that there was an ancient Greek tradition of complex mechanical technology that was later, at least in part, transmitted to the Byzantine and Islamic worlds, where mechanical devices which were complex, albeit simpler than the Antikythera mechanism, were built ...

Modern scholarship identifies three major stages in monumental sculpture in bronze and stone: the Archaic (from about 650 to 480 BC), Classical (480–323 BC ...
Ancient Greek technology developed during the 5th century BC, continuing up to and including the Roman period, and beyond.

Greek coins are the only art form from the ancient Greek world which can still be bought and owned by private collectors of modest means. The most widespread coins, used far beyond their native territories and copied and forged by others, were the Athenian tetradrachm , issued from c. 510 to c. 38 BC , and in the Hellenistic age the Macedonian ...
The disadvantages of using the pointing machine are a great loss of directness and the risk of loss of expression. Famous sculptors increasingly tended to use assistants. Sometimes a sculptor would run a large workshop with dozens of assistants and pupils. Art academies were formed where the skills of sculpture were taught in detail.
Today the formal patterns of classical Greek sculpture, its humanism and emphasis on the nude have found a new way to impress society, influencing the conception of beauty and practices regarding the body, resurrecting a cultivation of the physical that was born with the Greeks and influences various customs related to sexuality and the concept ...
The art of ancient Greece has exercised an enormous influence on the culture of many countries from ancient times until the present, particularly in the areas of sculpture and architecture. In the West, the art of the Roman Empire was largely derived from Greek models.
