The 17th century, also referred to as the 1600s, spanned the years 1601 to 1700.
During the 17th century major changes in philosophy and science took place. Before the 17th century began, science and scientists were not truly recognized. In fact, at first people like the 17th century genius Isaac Newton were called natural philosophers, since there was no concept of the word scientist for most of the 17th century.
The intrusion of newly invented machines became part of the daily and economic lives of 17th century folk. During the 17th century, the science of chemistry developed from medieval alchemy, and the 17th century science of astronomy evolved from astology.
By the end of the 17th century, a scientific revolution had occurred and science had become an established mathematical, mechanical, and empirical body of knowledge. Galileo Galilei, René Descartes, Blaise Pascal, Isaac Newton, and others had become noted scientists.
