From a single print shop in Mainz, Germany around 1440, the movable type printing-press had spread to no less than around 270 cities in Central, Western and Eastern Europe and had already produced more than 20 million volumes by the end of the 15th century. Printing made scholarly books more widely accessible, allowing researchers to consult ancient texts freely and to compare their own observations with those of fellow scholars. Printing ended the manuscript culture of the Middle Ages, where facts were few and far between, and replaced it with a printing culture where reliable and documented facts rapidly proliferated and became the secure foundation for scientific knowledge.
In the 16th century, Nicolaus Copernicus formulated a heliostatic model of the Solar System, with the Sun positioned near the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular motions, modified by epicycles, and at uniform speeds. The Copernican model challenged the dominant geocentric model of Ptolemy, which had placed Earth at the center of the Universe. 16th-century astronomers believed that Copernicus' elimination of the equant was his chief achievement but his model never displaced Ptolemy's, which only fell out of favor 70 years later after Galileo's telescopic observations of 1610.

=== Scientific Revolution ===

Tycho Brahe's unprecedentedly accurate astronomical observations in the late 16th century and Galileo Galilei’s early 17th-century telescopic observations combined to turn astronomy into the first modern science. Galileo's observations ended a millenium of pre-modern astronomical orthodoxy while Johannes Kepler used Brahe's data to discover that planets have elliptical, not circular, orbits and develop the laws of planetary motion. Because of Kepler, astronomical phenomena came to be seen as being governed by physical laws. The "New Science" that ultimately emerged by the end of the 17th century broke sharply with the natural philosophy that had preceded it, departed from previous Greek conceptions and traditions, was more mechanistic in its worldview and more integrated with mathematics, and was obsessed with the acquisition and interpretation of new evidence.

=== Age of Enlightenment ===

At the start of the Age of Enlightenment, Isaac Newton formed the foundation of classical mechanics by his Philosophiæ Naturalis Principia Mathematica greatly influencing future physicists. Gottfried Wilhelm Leibniz incorporated terms from Aristotelian physics, now used in a new non-teleological way. This implied a shift in the view of objects: objects were now considered as having no innate goals. Leibniz assumed that different types of things all work according to the same general laws of nature, with no special formal or final causes.
During this time the declared purpose and value of science became producing wealth and inventions that would improve human lives, in the materialistic sense of having more food, clothing, and other things. In Bacon's words, "the real and legitimate goal of sciences is the endowment of human life with new inventions and riches", and he discouraged scientists from pursuing intangible philosophical or spiritual ideas, which he believed contributed little to human happiness beyond "the fume of subtle, sublime or pleasing [speculation]".
Science during the Enlightenment was dominated by scientific societies and academies, which had largely replaced universities as centres of scientific research and development. Societies and academies were the backbones of the maturation of the scientific profession. Another important development was the popularisation of science among an increasingly literate population. Enlightenment philosophers turned to a few of their scientific predecessors – Galileo, Kepler, Boyle, and Newton principally – as the guides to every physical and social field of the day.
The 18th century saw significant advancements in the practice of medicine and physics; the development of biological taxonomy by Carl Linnaeus; a new understanding of magnetism and electricity; and the maturation of chemistry as a discipline. Ideas on human nature, society, and economics evolved during the Enlightenment. Hume and other Scottish Enlightenment thinkers developed A Treatise of Human Nature, which was expressed historically in works by authors including James Burnett, Adam Ferguson, John Millar and William Robertson, all of whom merged a scientific study of how humans behaved in ancient and primitive cultures with a strong awareness of the determining forces of modernity. Modern sociology largely originated from this movement. In 1776, Adam Smith published The Wealth of Nations, which is often considered the first work on modern economics.
