  Applied innovation extended to commerce. At the end of the 15th century, Luca Pacioli published the first work on bookkeeping, making him the founder of accounting.
  
  The rediscovery of ancient texts and the invention of the printing press in about 1440 democratized learning and allowed a faster propagation of more widely distributed ideas. In the first period of the Italian Renaissance, humanists favored the study of humanities over natural philosophy or applied mathematics, and their reverence for classical sources further enshrined the Aristotelian and Ptolemaic views of the universe. Writing around 1450, Nicholas of Cusa anticipated the heliocentric worldview of Copernicus, but in a philosophical fashion.
  
  Science and art were intermingled in the early Renaissance, with polymath artists such as Leonardo da Vinci making observational drawings of anatomy and nature. Leonardo set up controlled experiments in water flow, medical dissection, and systematic study of movement and aerodynamics, and he devised principles of research method that led Fritjof Capra to classify him as the "father of modern science". Other examples of Da Vinci's contribution during this period include machines designed to saw marbles and lift monoliths, and new discoveries in acoustics, botany, geology, anatomy, and mechanics.
  
  A suitable environment had developed to question classical scientific doctrine. The discovery in 1492 of the New World by Christopher Columbus challenged the classical worldview. The works of Ptolemy (in geography) and Galen (in medicine) were found to not always match everyday observations. As the Reformation and Counter-Reformation clashed, the Northern Renaissance showed a decisive shift in focus from Aristotelean natural philosophy to chemistry and the biological sciences (botany, anatomy, and medicine). The willingness to question previously held truths and search for new answers resulted in a period of major scientific advancements.
  
  Some view this as a " scientific revolution ", heralding the beginning of the modern age, others as an acceleration of a continuous process stretching from the ancient world to the present day. Significant scientific advances were made during this time by Galileo Galilei, Tycho Brahe, and Johannes Kepler. Copernicus, in De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres), posited that the Earth moved around the Sun. De humani corporis fabrica (On the Workings of the Human Body) by Andreas Vesalius, gave a new confidence to the role of dissection, observation, and the mechanistic view of anatomy.
  
  Another important development was in the process for discovery, the scientific method, focusing on empirical evidence and the importance of mathematics, while discarding much of Aristotelian science. Early and influential proponents of these ideas included Copernicus, Galileo, and Francis Bacon. The new scientific method led to great contributions in the fields of astronomy, physics, biology, and anatomy.
