The Silurian hypothesis is a thought experiment, [1] which assesses modern science's ability to detect evidence of a prior advanced civilization, perhaps several million years ago. The most probable clues for such a civilization could be carbon , radioactive elements or temperature variation.
[3] The history of knowledge's subject matter is undefined and critics contend the field's vague scope. [3] One reason for this is the specializations of academics working within this discipline are broad. [3] In contrast, drawing knowledge from other disciplines is considered advantageous to the field as it encourages cooperation between ...
Babylonian astronomy was "the first and highly successful attempt at giving a refined mathematical description of astronomical phenomena." [2] According to the historian Asger Aaboe, "all subsequent varieties of scientific astronomy, in the Hellenistic world, in India, in Islam, and in the West—if not indeed all subsequent endeavour in the exact sciences—depend upon Babylonian astronomy in ...
The Ptolemaic system of celestial motion as depicted in the Harmonia Macrocosmica (1661). Science in classical antiquity encompasses inquiries into the workings of the world or universe aimed at both practical goals (e.g., establishing a reliable calendar or determining how to cure a variety of illnesses) as well as more abstract investigations belonging to natural philosophy.
This article includes the advances in technology and the development of several engineering sciences in historic times before the Middle Ages, which began after the fall of the Western Roman Empire in AD 476, [1] [2] the death of Justinian I in the 6th century, [3] the coming of Islam in the 7th century, [4] or the rise of Charlemagne in the ...
The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature.
The ancient Mesopotamians had extensive knowledge about the chemical properties of clay, sand, metal ore, bitumen, stone, and other natural materials, and applied this knowledge to practical use in manufacturing pottery, faience, glass, soap, metals, lime plaster, and waterproofing. Metallurgy required knowledge about the properties of metals.
Byzantine scientists preserved and continued the legacy of the great Ancient Greek mathematicians and put mathematics in practice. In early Byzantium (5th to 7th century) the architects and mathematicians Isidore of Miletus and Anthemius of Tralles developed mathematical formulas to construct the great Hagia Sophia church, a technological breakthrough for its time and for centuries afterwards ...
