Scientific Revolution
1543 (Copernicus) – c. 1700· Idea, religion or movement· Europe
Well documentedSolid records, physical evidence or scientific consensus.
Between about 1543 and 1700, European thinkers replaced ancient authority with observation, experiment and mathematics to explain nature.
See it on the History map →What happened
In 1543 Copernicus put the Sun, not Earth, at the center of the planets, and Vesalius corrected ancient anatomy by dissecting bodies. Kepler found that planets move in ellipses; Galileo turned a telescope on the sky; William Harvey showed the heart pumps blood in a circuit. Francis Bacon and René Descartes argued for new methods of finding truth. Societies like London's Royal Society (1660) shared results. Newton's Principia (1687) tied it together with laws of motion and gravity.
Why it matters
It created modern science's method: test ideas against evidence and express laws in math. That method later drove industrial technology, medicine and the Enlightenment's faith in reason.
How we know
The original books and letters survive, from Copernicus's On the Revolutions to Newton's Principia, along with notebooks, instruments and the published proceedings of scientific societies.
Still debated
Some historians question whether it was a single 'revolution' at all, and how much it owed to medieval, Islamic and craftsmen's knowledge.

Connections (3)
▸The Renaissance led to Scientific RevolutionMostly agreed
The connection
Humanists recovered and printed ancient scientific works by Ptolemy, Archimedes, Euclid and Galen, giving scholars texts to test and correct. Renaissance artists practiced anatomy, perspective and precise observation; Vesalius's 1543 anatomy book relied on artists' detailed drawings. Copernicus studied in Renaissance Italy, and patrons such as the Medici funded scientists, including Galileo.
When and how
Italy and central Europe, about 1450–1610; Leonardo da Vinci, Copernicus at Bologna and Padua (1496–1503), Vesalius at Padua, and Galileo under Medici patronage.
How sure are we?
Copernicus and Vesalius cite ancient texts recovered by humanists, and their training at Italian universities is documented.
Debates and open questions
Some historians stress the medieval and Islamic roots of science instead, and note that many humanists revered ancient authority more than experiment.
▸Galileo Galilei became a hero of the Scientific RevolutionMostly agreed
The connection
Galileo's telescope discoveries gave public, visible evidence for Copernicus, and his experiments showed that nature obeys mathematical laws. He wrote in Italian for a wide audience. His 1633 trial made him a symbol of free inquiry, and his work on motion fed directly into Newton's laws, published 45 years after Galileo died.
When and how
Padua, Florence and Rome, 1609–1642; Galileo, his Medici patrons, Pope Urban VIII and the Roman Inquisition.
How sure are we?
His books, The Starry Messenger (1610), the Dialogue (1632) and Two New Sciences (1638), were widely read; Newton credited him in the Principia.
Debates and open questions
His heroic image owes much to later writers; he was wrong on some points, such as the cause of tides, and ignored Kepler's ellipses.
▸Vaccines and germ theory grew out of the methods of the Scientific RevolutionMostly agreed
The connection
The Scientific Revolution taught that claims must be tested by observation and experiment, and supplied tools like the microscope; Antonie van Leeuwenhoek first saw bacteria with one in the 1670s. Jenner tested his cowpox idea on patients and published the cases. Pasteur and Koch proved germs cause disease through controlled experiments, putting medicine on a scientific footing.
When and how
Delft, Netherlands, 1670s (Leeuwenhoek); Gloucestershire, England, 1796 (Jenner); Paris and Berlin, 1860s to 1880s (Pasteur and Koch).
How sure are we?
Leeuwenhoek's letters to London's Royal Society, Jenner's 1798 report, Pasteur's swan-neck flask experiments, and Koch's postulates, his rules for proving a germ causes a disease.
Debates and open questions
About two centuries passed between first seeing microbes and linking them to disease; why medicine took so long to adopt experimental methods is debated.
