The main focus of the scientific revolution during the Renaissance was the re-examination and questioning of traditional beliefs about the natural world, emphasizing observation, experimentation, and the scientific method. This period, spanning the 16th and 17th centuries, saw significant advancements in various fields, including astronomy, physics, biology, and mathematics. Notable figures such as Copernicus, Galileo, and Newton challenged established doctrines, leading to groundbreaking discoveries that laid the foundations for modern science. This shift in thinking encouraged a more systematic approach to understanding nature, ultimately paving the way for the Enlightenment and the development of contemporary scientific inquiry.
