|barometer. A barometer measures changes in the pressure of the atmosphere. Evangelista Torricelli invented the barometer in the 1640s. Torricelli filled a glass tube with a heavy liquid called mercury. Then he placed the tube upside down in a dish.
Over the next few days, Torricelli watched the tube. He saw that the height of the mercury did not stay the same. The column of mercury moved up and down as the pressure in the atmosphere changed. The barometer soon proved to be a valuable tool in studying and predicting the weather.
Galileo likely made the first thermometer. In the early 1700s, a German scientist, Daniel Gabriel Fahrenheit, made thermometers more accurate. He put mercury in a glass tube. As the mercury grew warmer, it expanded and rose up the tube. The height of the mercury provided a measure of temperature. Fahrenheit also designed a new temperature scale. In the United States, we still measure temperature using Fahrenheit degrees.
With new tools and the scientific method, scientists made rapid advances in their understanding of nature. Their work had many practical results, such as the invention of the steam engine. As new technologies developed, Europeans used them to become the commercial and industrial leaders of the world. Science is one of the most powerful forces shaping our world today.
Antonie van Leeuwenhoek observed microorganisms through microscopes that he designed.

34.8 Chapter Summary
In this chapter, you learned about the Scientific Revolution. This movement marked a major shift in the way people thought about the natural world.
Several factors contributed to the Scientific Revolution. Renaissance thinkers questioned traditional learning and observed nature for themselves. Translations of classical texts exposed scholars to new ideas. Discoveries by explorers showed that accepted ideas could be wrong.
The Scientific Revolution began when Copernicus proposed the daring idea that Earth and the other planets traveled around the sun. Kepler built on this work by correctly describing the planets’ orbits. Galileo’s discoveries supported the Copernican theory.
Newton took all this work a giant step forward. His law of gravity explained why planets orbited the sun. Newton also showed that the same laws applied everywhere in the known universe.
The ideas of Bacon and Descartes helped to shape the scientific method, which proved to be a powerful way of testing ideas about nature. New tools like the microscope and the thermometer also aided scientific progress.
Europeans were dazzled by rapid advances in science. Many were inspired to take a similar approach to problems of human life and society. You’ll learn about these thinkers in the next chapter.
Today’s high-powered microscopes are based on the first designs from the 1600s. Scientific research would not be possible without such inventions.
