About Evangelista Torricelli

Evangelista Torricelli (1568-1647) was an Italian physicist and mathematician who made significant contributions to the fields of fluid dynamics, hydrostatics, and optics during the Scientific Revolution. Born in Faenza, Italy on October 15, 1568, Torricelli grew up in a family of modest means. His early education was focused on the classics, but his aptitude for mathematics and science soon became apparent. Torricelli's intellectual journey began under the tutelage of Cristofano Tibaldi, a local mathematician and engineer. He later moved to Bologna, where he studied at the University of Bologna and came under the influence of Galileo Galilei, who recognized his extraordinary talent. One of Torricelli's most famous works is the invention of the mercury barometer in 1643. This device, which measures atmospheric pressure using a column of liquid, was a groundbreaking achievement and is still used today. The Torricellian vacuum, or the space above the column of mercury in the barometer, demonstrated that there was indeed something beyond the earth's atmosphere – a concept that challenged contemporary understanding. Torricelli also made significant contributions to optics, including the study of refraction and the design of telescopes. He wrote several treatises on these subjects, including "Exercitationes Geometricae Sex" (1644), which contains his laws of refraction and is considered one of the most important works in the history of optics. Despite his significant contributions to science, Torricelli's life was marked by personal tragedy. He suffered from poor health throughout his life and lost both of his sons at a young age. He died in Faenza on October 25, 1647, having left an indelible mark on the scientific world. His legacy as a pioneer in fluid dynamics, hydrostatics, and optics continues to inspire scientists today.

Interpretations of Popular Quotes

"What nature has joined together, let no man put asunder."

This quote by Evangelista Torricelli underscores the idea that what nature has naturally formed or united should not be artificially separated or divided by humans. It emphasizes the importance of preserving natural phenomena and relationships, rather than interfering or disrupting them unnecessarily. In broader contexts, it can also imply respect for natural harmony, unity, and balance in various aspects of life, including science, ethics, society, and environment.


"The law of nature and of nations is, that whatsoever a body is in equilibrium with, it will remain at rest, provided the same conditions persist."

This quote from Evangelista Torricelli highlights the principle of balance and stability in both physical and societal systems. In a physical sense, it suggests that objects will remain stationary if they are in equilibrium with their environment, and changes in conditions could lead to motion or instability. In society, it can be interpreted as the idea that peace and stability are maintained when there is harmony between individuals and nations, and disruptions or conflicts may occur when conditions change or imbalances arise. It emphasizes the importance of maintaining equilibrium and balance for continued peace and stability in both physical and social environments.


"If we wish to find out the nature of anything, we ought first to shut the door on everything else."

This quote by Evangelista Torricelli emphasizes the importance of focused attention and eliminating distractions when investigating or understanding something new. In other words, to truly grasp the essence of any subject or phenomenon, it is essential to minimize external influences and distractions, so as not to be misled or confused. This approach encourages deep, systematic inquiry and fosters clearer insights and understanding.


"In nature, nothing is created, nothing is destroyed, and everything changes."

This quote by Evangelista Torricelli underscores the principle of conservation of matter in nature. It suggests that while physical materials may not be 'created' or 'destroyed', their forms, states, and compositions undergo continuous transformations as part of the larger natural cycle. This idea is fundamental to understanding the interconnectedness and sustainability within our natural world.


"The heavens themselves, as it were, must be weighed before they can be measured."

This quote by Evangelista Torricelli suggests that understanding or measuring the vastness and complexity of the universe requires a deep level of comprehension and precision. It implies that our knowledge and instruments must be as comprehensive as the celestial bodies themselves before we can accurately measure them. In other words, the task of exploring the universe is challenging, demanding extraordinary effort and insights to achieve meaningful measurement and understanding.


Many have argued that a vacuum does not exist, others claim it exists only with difficulty in spite of the repugnance of nature; I know of no one who claims it easily exists without any resistance from nature.

The Geometer has the special privilege to carry out, by abstraction, all constructions by means of the intellect. Who, then, would wish to prevent me from freely considering figures hanging on a balance imagined to be at an infinite distance beyond the confines of the world?

Is it a surprise that into the vessel, in which the mercury has no inclination and no repugnance, not even the slightest, to being there, it should enter and should rise in a column high enough to make equilibrium with the weight of the external air which forces it up?

Surprise, Which, Inclination, Vessel

We have made many glass vessels... with tubes two cubits long. These were filled with mercury, the open end was closed with the finger, and the tubes were then inverted in a vessel where there was mercury.
