An introduction to the life of archimedes

Science as natural philosophy Precritical science Science, as it has been defined above, made its appearance before writing. It is necessary, therefore, to infer from archaeological remains what was the content of that science.

Science as natural philosophy

From cave paintings and from apparently regular scratches on bone and reindeer horn, it is known that prehistoric humans were close observers of nature who carefully tracked the seasons and times of the year. About bce there was a sudden burst of activity that seems to have had clear scientific importance.

Great Britain and northwestern Europe contain large stone structures from that era, the most famous of which is Stonehenge on the Salisbury Plain in England, that are remarkable from a scientific point of view.

Not only do they reveal technical and social skills of a high order—it was no mean feat to move such enormous blocks of stone considerable distances and place them in position—but the basic conception of Stonehenge and the other megalithic structures also seems to combine religious and astronomical purposes.

Their layouts suggest a degree of mathematical sophistication that was first suspected only in the midth century. Stonehenge is a circle, but some of the other megalithic structures are egg-shaped and, apparently, constructed on mathematical principles that require at least practical knowledge of the Pythagorean theorem that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

This theorem, or at least the Pythagorean numbers that can be generated by it, seems to have been known throughout Asia, the Middle Eastand Neolithic Europe two millennia before the birth of Pythagoras.

This combination of religion and astronomy was fundamental to the early history of science. It is found in Mesopotamia, Egypt, China although to a much lesser extent than elsewhereCentral Americaand India. The spectacle of the heavens, with the clearly discernible order and regularity of most heavenly bodies highlighted by extraordinary events such as comets and novae and the peculiar motions of the planets, obviously was an irresistible intellectual puzzle to early humankind.

In its search for order and regularity, the human mind could do no better than to seize upon the heavens as the paradigm of certain knowledge. Astronomy was to remain the queen of the sciences welded solidly to theology for the next 4, years.

Science, in its mature form, developed only in the West. But it is instructive to survey the protoscience that appeared in other areas, especially in light of the fact that until quite recently this knowledge was often, as in China, far superior to Western science. China As has already been noted, astronomy seems everywhere to have been the first science to emerge.

Its intimate relation to religion gave it a ritual dimension that then stimulated the growth of mathematics. Chinese savantsfor example, early devised a calendar and methods of plotting the positions of stellar constellations.

Since changes in the heavens presaged important changes on the Earth for the Chinese considered the universe to be a vast organism in which all elements were connectedastronomy and astrology were incorporated into the system of government from the very dawn of the Chinese state in the 2nd millennium bce.

As the Chinese bureaucracy developed, an accurate calendar became absolutely necessary to the maintenance of legitimacy and order.

The result was a system of astronomical observations and records unparalleled elsewhere, thanks to which there are, today, star catalogs and observations of eclipses and novae that go back for millennia.

In other sciences too the overriding emphasis was on practicality, for the Chinese, almost alone among ancient peoples, did not fill the cosmos with gods and demons whose arbitrary wills determined events.

Order was inherent and, therefore, expected. It was for humans to detect and describe this order and to profit from it. Chemistry or, rather, alchemymedicine, geologygeographyand technology were all encouraged by the state and flourished.

Practical knowledge of a high order permitted the Chinese to deal with practical problems for centuries on a level not attained in the West until the Renaissance. India Astronomy was studied in India for calendrical purposes to set the times for both practical and religious tasks.

Primary emphasis was placed on solar and lunar motions, the fixed stars serving as a background against which these luminaries moved. Indian mathematics seems to have been quite advanced, with particular sophistication in geometrical and algebraic techniques.

This latter branch was undoubtedly stimulated by the flexibility of the Indian system of numeration that later was to come into the West as the Hindu-Arabic numerals. America Quite independently of China, India, and the other civilizations of Europe and Asia, the Maya of Central America, building upon older culturescreated a complex society in which astronomy and astrology played important roles.

Determination of the calendar, again, had both practical and religious significance. Solar and lunar eclipses were important, as was the position of the bright planet Venus.

No sophisticated mathematics are known to have been associated with this astronomy, but the Mayan calendar was both ingenious and the result of careful observation.

The Middle East In the cradles of Western civilization in Egypt and Mesopotamiathere were two rather different situations. In Egypt there was an assumption of cosmic order guaranteed by a host of benevolent gods. Unlike China, whose rugged geography often produced disastrous floods, earthquakes, and violent storms that destroyed crops, Egypt was surpassingly placid and delightful.

Egyptians found it difficult to believe that all ended with death. Enormous intellectual and physical labour, therefore, was devoted to preserving life after death. Both Egyptian theology and the pyramids are testaments to this preoccupation. All of the important questions were answered by religion, so the Egyptians did not concern themselves overmuch with speculations about the universe.

None of this required much mathematics, and there was, consequently, little of any importance.I have a love/hate relationship with calculus: it demonstrates the beauty of math and the agony of math education.

Precritical science

On the simplest level, science is knowledge of the world of nature. There are many regularities in nature that humankind has had to recognize for survival since the emergence of Homo sapiens as a species.

The Sun and the Moon periodically repeat their movements.
