- Scientific revolution
The Scientific Revolution is an era associated primarily with the 16th and 17th centuries during which new ideas and knowledge in physics, astronomy, biology, medicine and chemistry transformed medieval and ancient views of nature and laid the foundations for modern science. According to most accounts, the scientific revolution began in Europe towards the end of the Renaissance era and continued through the late 18th century, the later period known as The Enlightenment. It was sparked by the publication in 1543 of two works that changed the course of science: Nicolaus Copernicus's De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) and Andreas Vesalius's De humani corporis fabrica (On the Fabric of the Human body).

Significance of the revolution
The science of the middle ages was significant in establishing a base for modern science. The Marxist historian and scientist J. D. Bernal asserted that "the renaissance enabled a scientific revolution which let scholars look at the world in a different light. Religion, superstition, and fear were replaced by reason and knowledge". James Hannam says that, while most historians do think something revolutionary happened at this time, that "the term 'scientific revolution' is another one of those prejudicial historical labels that explain nothing. You could call any century from the twelfth to the twentieth a revolution in science" and that the concept "does nothing more than reinforce the error that before Copernicus nothing of any significance to science took place". Despite some challenges to religious views, however, many notable figures of the scientific revolution—including Nicolaus Copernicus, Tycho Brahe, Johannes Kepler, Galileo Galilei, and Isaac Newton—remained devout in their faith.
This period saw a fundamental transformation in scientific ideas across physics, astronomy, and biology, in institutions supporting scientific investigation, and in the more widely held picture of the universe. The scientific revolution led to the establishment of several modern sciences.
Many contemporary writers and modern historians claim that there was a revolutionary change in world view. In 1611 the English poet, John Donne, wrote:[The] new Philosophy calls all in doubt,
The Element of fire is quite put out;Can well direct him where to look for it
The Sun is lost, and th'earth, and no man's wit
Mid-20th century historian Herbert Butterfield was less disconcerted, but nevertheless saw the change as fundamental:Since that revolution turned the authority in English not only of the Middle Ages but of the ancient world—since it started not only in the eclipse of scholastic philosophy but in the destruction of Aristotelian physics—it outshines everything since the rise of Christianity and reduces the Renaissance and Reformation to the rank of mere episodes, mere internal displacements within the system of medieval Christendom.... [It] looms so large as the real origin both of the modern world and of the modern mentality that our customary periodization of European history has become an anachronism and an encumbrance.
More recently, sociologist and historian of science Steven Shapin opened his book, The Scientific Revolution, with the paradoxical statement: "There was no such thing as the Scientific Revolution, and this is a book about it." Although historians of science continue to debate the exact meaning of the term, and even its validity, the scientific revolution still remains a useful concept to interpret the many changes in science.
The scientific revolution was not marked by any single change. The following new ideas contributed to what is called the scientific revolution:
- The replacement of the Earth as center of the universe by Heliocentrism
- Deprecation of the Aristotelian theory that matter was continuous and made up of the elements Earth, Water, Air, and Fire because its classic rival, Atomism, better lent itself to a “mechanical philosophy” of matter.
- The replacement of the Aristotelian idea that heavy bodies, by their nature, moved straight down toward their natural places; that light bodies, by their nature, moved straight up toward their natural place; and that ethereal bodies, by their nature, moved in unchanging circular motions with the idea that all bodies are heavy and move according to the same physical laws
- Inertia replaced the medieval impetus theory, that unnatural motion (“forced” or “violent” rectilinear motion) is caused by continuous action of the original force imparted by a mover into that which is moved.
- The replacement of Galen's treatment of the venous and arterial systems as two separate systems with William Harvey's concept that blood circulated from the arteries to the veins "impelled in a circle, and is in a state of ceaseless motion"
However, according to Galileo, the core of what came to be known as the scientific method in modern physical sciences is stated in his book Il Saggiatore to be the concept of a systematic, mathematical interpretation of experiments and empirical facts:
"Philosophy [i.e., physics] is written in this grand book—I mean the universe—which stands continually open to our gaze, but it cannot be understood unless one first learns to comprehend the language and interpret the characters in which it is written. It is written in the language of mathematics, and its characters are triangles, circles, and other geometrical figures, without which it is humanly impossible to understand a single word of it; without these, one is wandering around in a dark labyrinth."
Many of the important figures of the scientific revolution, however, shared in the Renaissance respect for ancient learning and cited ancient pedigrees for their innovations. Nicolaus Copernicus (1473–1543), Kepler (1571–1630), Newton (1642–1727) and Galileo Galilei (1564–1642) all traced different ancient and medieval ancestries for the heliocentric system. In the Axioms Scholium of his Principia Newton said its axiomatic three laws of motion were already accepted by mathematicians such as Huygens (1629–1695), Wallace, Wren and others, and also in memos in his draft preparations of the second edition of the Principia he attributed its first law of motion and its law of gravity to a range of historical figures. According to Newton himself and other historians of science, his Principia's first law of motion was the same as Aristotle's counterfactual principle of interminable locomotion in a void stated in Physics 4.8.215a19—22 and was also endorsed by ancient Greek atomists and others. As Newton expressed himself:All those ancients knew the first law [of motion] who attributed to atoms in an infinite vacuum a motion which was rectilinear, extremely swift and perpetual because of the lack of resistance... Aristotle was of the same mind, since he expresses his opinion thus...[in Physics 4.8.215a19-22], speaking of motion in the void [in which bodies have no gravity and] where there is no impediment he writes: 'Why a body once moved should come to rest anywhere no one can say. For why should it rest here rather than there ? Hence either it will not be moved, or it must be moved indefinitely, unless something stronger impedes it.'
As Newton attests, the Principia's first law of motion was known in antiquity, even by Aristotle, although its significance, as such, went unappreciated. This refutes Kuhn's thesis of a scientific revolution in dynamics.
The geocentric model was nearly universally accepted until 1543 when Nicolaus Copernicus published his book entitled De revolutionibus orbium coelestium and was widely accepted into the next century. At around the same time, the findings of Vesalius corrected the previous anatomical teachings of Galen, which were based upon the dissection of animals even though they were supposed to be a guide to the human body.
Andreas Vesalius (1514–1564) was an author of one of the most influential books on human anatomy, De humani corporis fabrica, also in 1543. French surgeon Ambroise Paré (c.1510–1590) is considered as one of the fathers of surgery; he was leader in surgical techniques and battlefield medicine, especially the treatment of wounds. Partly based on the works by the Italian surgeon and anatomist Matteo Realdo Colombo (c. 1516 – 1559), the anatomist William Harvey (1578–1657) described the circulatory system. Herman Boerhaave (1668–1738) is sometimes referred to as a "father of physiology" due to his exemplary teaching in Leiden and textbook 'Institutiones medicae' (1708).
It was between 1650 and 1800 that the science of modern dentistry developed. It is said that the 17th century French physician Pierre Fauchard (1678–1761) started dentistry science as we know it today, and he has been named "the father of modern dentistry".
Pierre Vernier (1580–1637) was inventor and eponym of the vernier scale used in measuring devices. Evangelista Torricelli (1607–1647) was best known for his invention of the barometer. Although Franciscus Vieta (1540–1603) gave the first notation of modern algebra, John Napier (1550–1617) invented logarithms, and Edmund Gunter (1581–1626) created the logarithmic scales (lines, or rules) upon which slide rules are based. It was William Oughtred (1575–1660) who first used two such scales sliding by one another to perform direct multiplication and division; and thus is credited as the inventor of the slide rule in 1622.
Blaise Pascal (1623–1662) invented the mechanical calculator in 1642. The introduction of his Pascaline in 1645 launched the development of mechanical calculators first in Europe and then all over the world. He also made important contributions to the study of fluid and clarified the concepts of pressure and vacuum by generalizing the work of Evangelista Torricelli. He wrote a significant treatise on the subject of projective geometry at the age of sixteen, and later corresponded with Pierre de Fermat (1601–1665) on probability theory, strongly influencing the development of modern economics and social science.
Gottfried Leibniz (1646–1716), building on Pascal's work, became one of the most prolific inventors in the field of mechanical calculators ; he was the first to describe a pinwheel calculator in 1685 and invented the Leibniz wheel, used in the arithmometer, the first mass-produced mechanical calculator. He also refined the binary number system, foundation of virtually all modern computer architectures.
John Hadley (1682–1744) was mathematician inventor of the octant, the precursor to the sextant. Hadley also developed ways to make precision aspheric and parabolic objective mirrors for reflecting telescopes, building the first parabolic Newtonian telescope and a Gregorian telescope with accurately shaped mirrors.
Denis Papin (1647–1712) was best known for his pioneering invention of the steam digester, the forerunner of the steam engine. Abraham Darby I (1678–1717) was the first, and most famous, of three generations with that name in an Abraham Darby family that played an important role in the Industrial Revolution. He developed a method of producing high-grade iron in a blast furnace fuelled by coke rather than charcoal. This was a major step forward in the production of iron as a raw material for the Industrial Revolution. Thomas Newcomen (1664–1729) perfected a practical steam engine for pumping water, the Newcomen steam engine. Consequently, he can be regarded as a forefather of the Industrial Revolution.
In 1672, Otto von Guericke (1602–1686), was the first human on record to knowingly generate electricity using a machine, and in 1729, Stephen Gray (1666–1736) demonstrated that electricity could be "transmitted" through metal filaments. The first electrical storage device was invented in 1745, the so-called "Leyden jar", and in 1749, Benjamin Franklin (1706–1790) demonstrated that lightning was electricity. In 1698 Thomas Savery (c.1650–1715) patented an early steam engine.
German scientist Georg Agricola (1494–1555), known as "the father of mineralogy", published his great work De re metallica. Robert Boyle (1627–1691) was credited with the discovery of Boyle's Law. He is also credited for his landmark publication The Sceptical Chymist, where he attempts to develop an atomic theory of matter. The person celebrated as the "father of modern chemistry" is Antoine Lavoisier (1743–1794) who developed his law of Conservation of mass in 1789, also called Lavoisier's Law. Antoine Lavoisier proved that burning was caused by oxidation, that is, the mixing of a substance with oxygen. He also proved that diamonds were made of carbon and argued that all living processes were at their heart chemical reactions. In 1766, Henry Cavendish (1731–1810) discovered hydrogen. In 1774, Joseph Priestley (1733–1804) discovered oxygen.
German physician Leonhart Fuchs (1501–1566) was one of the three founding fathers of botany, along with Otto Brunfels (1489- 1534) and Hieronymus Bock (1498–1554) (also called Hieronymus Tragus). Valerius Cordus (1515–1554) authored one of the greatest pharmacopoeias and one of the most celebrated herbals in history, Dispensatorium (1546).
In his Systema Naturae, published in 1767, Carl von Linné (1707–1778) catalogued all the living creatures into a single system that defined their morphological relations to one another: the Linnean classification system. He is often called the "Father of Taxonomy". Georges Buffon (1707–1788), was perhaps the most important of Charles Darwin’s predecessors. From 1744 to 1788, he wrote his monumental Histoire naturelle, générale et particulière, which included everything known about the natural world up until that date.
Along with the inventor and microscopist Robert Hooke (1635–1703), Sir Christopher Wren (1632–1723) and Sir Isaac Newton (1642–1727), English scientist and astronomer Edmond Halley (1656–1742) was trying to develop a mechanical explanation for planetary motion. Halley's star catalogue of 1678 was the first to contain telescopically determined locations of southern stars.
Many historians of science have seen other ancient and medieval antecedents of these ideas. It is widely accepted that Copernicus's De revolutionibus followed the outline and method set by Ptolemy in his Almagest and employed geometrical constructions that had been developed previously by the Maragheh school in his heliocentric model, and that Galileo's mathematical treatment of acceleration and his concept of impetus rejected earlier medieval analyses of motion, rejecting by name; Averroes, Avempace, Jean Buridan, and John Philoponus (see Theory of impetus).
The standard theory of the history of the scientific revolution claims the 17th century was a period of revolutionary scientific changes. It is claimed that not only were there revolutionary theoretical and experimental developments, but that even more importantly, the way in which scientists worked was radically changed. An alternative anti-revolutionist view is that science as exemplified by Newton's Principia was anti-mechanist and highly Aristotelian, being specifically directed at the refutation of anti-Aristotelian Cartesian mechanism, as evidenced in the Principia quotations below, and not more empirical than it already was at the beginning of the century or earlier in the works of scientists such as Benedetti, Galileo Galilei, or Johannes Kepler.
Ancient and medieval background
The scientific revolution was built upon the foundation of ancient Greek learning and science in the middle ages, as it had been elaborated and further developed by Roman/Byzantine science and medieval Islamic science. The "Aristotelian tradition" was still an important intellectual framework in by the 17th century, although by that time natural philosophers had moved away from much of it.
Key scientific ideas dating back to classical antiquity had changed drastically over the years, and in many cases been discredited. The ideas that remained, which would be transformed fundamentally during the scientific revolution, include:
- Aristotle's cosmology which placed the Earth at the center of a spherical hierarchic cosmos. The terrestrial and celestial regions were made up of different elements which had different kinds of natural movement.
- The terrestrial region, according to Aristotle, consisted of concentric spheres of the four elements—earth, water, air, and fire. All bodies naturally moved in straight lines until they reached the sphere appropriate to their elemental composition—their natural place. All other terrestrial motions were non-natural, or violent.
- The celestial region was made up of the fifth element, Aether, which was unchanging and moved naturally with uniform circular motion. In the Aristotelian tradition, astronomical theories sought to explain the observed irregular motion of celestial objects through the combined effects of multiple uniform circular motions.
- The Ptolemaic model of planetary motion: Based on the geometrical model of Eudoxus of Cnidus, Ptolemy's Almagest, demonstrated that calculations could compute the exact positions of the Sun, Moon, stars, and planets in the future and in the past, and showed how these computational models were derived from astronomical observations. As such they formed the model for later astronomical developments. The physical basis for Ptolemaic models invoked layers of spherical shells, though the most complex models were inconsistent with this physical explanation.
It is important to note that ancient precedent existed for alternative theories and developments which prefigured later discoveries in the area of physics and mechanics; but in the absence of a strong empirical tradition, dominance of the Aristotelian school, and in light of the limited number of works to survive translation in an era when many books were lost to warfare, such developments remained obscure for centuries and are traditionally held to have had little effect on the re-discovery of such phenomena; whereas the invention of the printing press made the wide dissemination of such incremental advances of knowledge commonplace. Meanwhile, however, significant progress in geometry, mathematics, and astronomy was made in the medieval era, particularly in the Islamic world as well as Europe.
New approaches to nature
Historians of the scientific revolution traditionally maintain that its most important changes were in the way in which scientific investigation was conducted, as well as the philosophy underlying scientific developments. Among the main changes are the mechanical philosophy, the chemical philosophy, empiricism, and the increasing role of mathematics.
The mechanical philosophy
Aristotle recognized four kinds of causes, and where applicable, the most important of them is the "final cause". The final cause was the aim, goal, or purpose of some natural process or man-made thing. Until the scientific revolution, it was very natural to see such aims, such as a child's growth, for example, leading to a mature adult. Intelligence was assumed only in the purpose of man-made artifacts; it was not attributed to other animals or to nature.
In “mechanical philosophy” no field or action at a distance is permitted, particles or corpuscles of matter are fundamentally inert. Motion is caused by direct physical collision. Where nature substances had previously been understood organically, the mechanical philosophers viewed them as machines. As a result, Newton's theory seemed like some kind of throwback to “spooky action at a distance”. According to Thomas Kuhn, he and Descartes held the teleological principle that God conserved the amount of motion in the universe:
Gravity, interpreted as an innate attraction between every pair of particles of matter, was an occult quality in the same sense as the scholastics' "tendency to fall" had been.... By the mid eighteenth century that interpretation had been almost universally accepted, and the result was a genuine reversion (which is not the same as a retrogression) to a scholastic standard. Innate attractions and repulsions joined size, shape, position and motion as physically irreducible primary properties of matter.
Newton had also specifically attributed the inherent power of inertia to matter, against the mechanist thesis that matter has no inherent powers. But whereas Newton vehemently denied gravity was an inherent power of matter, his collaborator Roger Cotes made gravity also an inherent power of matter, as set out in his famous preface to the Principia's 1713 second edition which he edited, and contra Newton himself. And it was Cotes's interpretation of gravity rather than Newton's that came to be accepted. (See also Entropic gravity).
The Chemical Philosophy
Chemistry, and its antecedent alchemy, became an increasingly important aspect of scientific thought in the course of the 16th and 17th centuries. The importance of chemistry is indicated by the range of important scholars who actively engaged in chemical research. Among them were the astronomer Tycho Brahe, the chemical physician Paracelsus, the Irish philosopher Robert Boyle, and the English philosophers Thomas Browne and Isaac Newton.
Unlike the mechanical philosophy, the chemical philosophy stressed the active powers of matter, which alchemists frequently expressed in terms of vital or active principles—of spirits operating in nature.
The Aristotelian scientific tradition's primary mode of interacting with the world was through observation and searching for "natural" circumstances through reasoning. Coupled with this approach was the belief that rare events which seemed to contradict theoretical models were aberrations, telling nothing about nature as it "naturally" was. During the scientific revolution, changing perceptions about the role of the scientist in respect to nature, the value of evidence, experimental or observed, led towards a scientific methodology in which empiricism played a large, but not absolute, role.
By the start of the scientific revolution, empiricism had already become an important component of science and natural philosophy. Prior thinkers, particularly nominalist William of Ockham in the early 14th century, had begun the intellectual movement toward empiricism. Under the influence of scientists and philosophers like Francis Bacon, a sophisticated empirical tradition was developed by the 16th century. Belief of natural and artificial circumstances was abandoned, and a research tradition of systematic experimentation was slowly accepted throughout the scientific community. Bacon's philosophy of using an inductive approach to nature—to abandon assumption and to attempt to simply observe with an open mind—was in strict contrast with the earlier, Aristotelian approach of deduction, by which analysis of known facts produced further understanding. In practice, of course, many scientists (and philosophers) believed that a healthy mix of both was needed—the willingness to question assumptions, yet also to interpret observations assumed to have some degree of validity.
At the end of the scientific revolution the organic, qualitative world of book-reading philosophers had been changed into a mechanical, mathematical world to be known through experimental research. Though it is certainly not true that Newtonian science was like modern science in all respects, it conceptually resembled ours in many ways. Many of the hallmarks of modern science, especially in respect to the institution and profession of science, would not become standard until the mid-19th century.
Scientific knowledge, according to the Aristotelians, was concerned with establishing true and necessary causes of things. To the extent that medieval natural philosophers used mathematical problems, they limited social studies to theoretical analyses of local speed and other aspects of life. The actual measurement of a physical quantity, and the comparison of that measurement to a value computed on the basis of theory, was largely limited to the mathematical disciplines of astronomy and optics in Europe.
In the 16th and 17th centuries, European scientists began increasingly applying quantitative measurements to the measurement of physical phenomena on the Earth. Galileo maintained strongly that mathematics provided a kind of necessary certainty that could be compared to God's: "With regard to those few mathematical propositions which the human intellect does understand, I believe its knowledge equals the Divine in objective certainty."
Key ideas and people that emerged from the 16th and 17th centuries:
- First printed edition of Euclid's Elements in 1482.
- Nicolaus Copernicus (1473–1543) published On the Revolutions of the Heavenly Spheres in 1543, which advanced the heliocentric theory of cosmology.
- Andreas Vesalius (1514–1564) published De Humani Corporis Fabrica (On the Fabric of the Human Body) (1543), which discredited Galen's views. He found that the circulation of blood resolved from pumping of the heart. He also assembled the first human skeleton from cutting open cadavers.
- Franciscus Vieta (1540–1603) published In Artem Analycitem Isagoge (1591), which gave the first symbolic notation of parameters in literal algebra.
- William Gilbert (1544–1603) published On the Magnet and Magnetic Bodies, and on the Great Magnet the Earth in 1600, which laid the foundations of a theory of magnetism and electricity.
- Tycho Brahe (1546–1601) made extensive and more accurate naked eye observations of the planets in the late 16th century. These became the basic data for Kepler's studies.
- Sir Francis Bacon (1561–1626) published Novum Organum in 1620, which outlined a new system of logic based on the process of reduction, which he offered as an improvement over Aristotle's philosophical process of syllogism. This contributed to the development of what became known as the scientific method.
- Galileo Galilei (1564–1642) improved the telescope, with which he made several important astronomical discoveries, including the four largest moons of Jupiter, the phases of Venus, and the rings of Saturn, and made detailed observations of sunspots. He developed the laws for falling bodies based on pioneering quantitative experiments which he analyzed mathematically.
- Johannes Kepler (1571–1630) published the first two of his three laws of planetary motion in 1609.
- William Harvey (1578–1657) demonstrated that blood circulates, using dissections and other experimental techniques.
- René Descartes (1596–1650) published his Discourse on the Method in 1637, which helped to establish the scientific method. He also started the method of deductive reasoning.
- Antonie van Leeuwenhoek (1632–1723) constructed powerful single lens microscopes and made extensive observations that he published around 1660, opening up the micro-world of biology.
- Isaac Newton (1643–1727) built upon the work of Kepler and Galileo. He showed that an inverse square law for gravity explained the elliptical orbits of the planets, and advanced the law of universal gravitation. His development of infinitesimal calculus opened up new applications of the methods of mathematics to science. Newton taught that scientific theory should be coupled with rigorous experimentation, which became the keystone of modern science.
In 1543 Copernicus' work on the heliocentric model of the solar system was published, in which he tried to demonstrate that the sun was the center of the universe. Few were bothered by this suggestion, and the pope and several archbishops were interested enough by it to want more detail. His model was later used to create the calendar of Pope Gregory XIII. For almost two millennia, the geocentric model had been accepted by all but a few astronomers. The idea that the earth moved around the sun, as advocated by Copernicus, was to most of his contemporaries doubtful. It contradicted not only empirical observation, due to the absence of an observable stellar parallax, but also Aristotelian philosophy.
The discoveries of Johannes Kepler and Galileo gave the theory credibility. Kepler was an astronomer who, using the accurate observations of Tycho Brahe, proposed that the planets move around the sun not in circular orbits, but in elliptical ones. Together with his other laws of planetary motion, this allowed him to create a model of the solar system that was an improvement over Copernicus' original system. Galileo's main contributions to the acceptance of the heliocentric system were his mechanics, the observations he made with his telescope, as well as his detailed presentation of the case for the system. Using an early theory of inertia, Galileo could explain why rocks dropped from a tower fall straight down even if the earth rotates. His observations of the moons of Jupiter, the phases of Venus, the spots on the sun, and mountains on the moon all helped to discredit the Aristotelian philosophy and the Ptolemaic theory of the solar system. Through their combined discoveries, the heliocentric system gained support, and at the end of the 17th century it was generally accepted by astronomers.
Kepler's laws of planetary motion and Galileo's mechanics culminated in the work of Isaac Newton. His laws of motion were to be the solid foundation of mechanics; his law of universal gravitation combined terrestrial and celestial mechanics into one great system that seemed to be able to describe the whole world in mathematical formulae.
Not only astronomy and mechanics were greatly changed. Optics, for instance, was revolutionized by people like Robert Hooke, Christiaan Huygens, René Descartes and, once again, Isaac Newton, who developed mathematical theories of light as either waves (Huygens) or particles (Newton). Similar developments could be seen in chemistry, biology and other sciences, although their full development into modern science was delayed for a century or more.
Not all historians of science are agreed that there was any revolution in the sixteenth or 17th century. The continuity thesis is the hypothesis that there was no radical discontinuity between the intellectual development of the Middle Ages and the developments in the Renaissance and early modern period. Thus the idea of an intellectual or scientific revolution following the Renaissance is—according to the continuity thesis—a myth. Some continuity theorists point to earlier intellectual revolutions occurring in the Middle Ages, usually referring to either a European "Renaissance of the 12th century" or a medieval "Muslim scientific revolution", as a sign of continuity.
Another contrary view has been recently proposed by Arun Bala in his dialogical history of the birth of modern science. Bala argues that the changes involved in the Scientific Revolution—the mathematical realist turn, the mechanical philosophy, the atomism, the central role assigned to the Sun in Copernican heliocentrism—have to be seen as rooted in multicultural influences on Europe. Islamic science gave the first exemplar of a mathematical realist theory with Alhazen's Book of Optics in which physical light rays traveled along mathematical straight lines. The swift transfer of Chinese mechanical technologies in the medieval era shifted European sensibilities to perceive the world in the image of a machine. The Hindu-Arabic numeral system, which developed in close association with atomism in India, carried implicitly a new mode of mathematical atomic thinking. And the heliocentric theory, which assigned central status to the Sun, as well as Newton's concept of force acting at a distance, were rooted in ancient Egyptian religious ideas associated with Hermeticism. Bala argues that by ignoring such multicultural impacts we have been led to a Eurocentric conception of the scientific revolution.
A third approach takes the term "renaissance" quite literally. A closer study of Greek Philosophy and Greek Mathematics demonstrates that nearly all of the so-called revolutionary results of the so-called scientific revolution were in actuality restatements of ideas that were in many cases older than those of Aristotle and in nearly all cases at least as old as Archimedes. Aristotle even explicitly argues against some of the ideas that were demonstrated during the scientific revolution, such as heliocentrism. The basic ideas of the scientific method were well known to Archimedes and his contemporaries, as demonstrated in the well known discovery of buoyancy. Atomism was first thought of by Leucippus and Democritus. This view of the scientific revolution reduces it to a period of relearning classical ideas that is very much an extension of the renaissance, specifically relearning ideas that originated with somebody other than Aristotle and particularly those rooted in the schools of Plato and Pythagoras. This view of the scientific revolution does not deny that a change occurred but argues that it was a reassertion of previous knowledge (a renaissance) and not the creation of new knowledge. It cites statements from Newton, Copernicus and others in favour of the Pythagorean worldview as evidence.

An impetus is an inner force impressed into a moving body from without. It thus contrasts with purely external forces like the action of air on projectiles in Aristotle, and with purely internal forces like the nature of the elements in Aristotle and his followers. Internal forces are found in other schools too, e.g. the Stoics, and impetus theories would be very common if all these forces counted as impetus."
Impetus theories also contrast with theories of inertia which replaced them in the seventeenth to eighteenth centuries. Thomas Kuhn has seen the introduction of these two theories into dynamics as constituting scientific revolutions, although he was speaking about fourteenth century impetus theory; before it was fully recognized that impetus theory is found in Antiquity.
According to inertial theories, some motion needs no force to keep it in being. Thus, according to Newton, a body persists in the same state of rest or rectilinear motion unless there is a force acting on it to the contrary.
Such inertial ideas are merely sporadic in Antiquity and not consciously attended to as a separate option. Aristotle, for example, argues in Phys. 4.8 that in a vacuum a moving body would never stop, but the possible implications for inertia are not discussed.
