Meaning and Definition
The vacuum created in the space above the mercury column in a barometer, as first demonstrated by Evangelista Torricelli in 1643.
The near-perfect vacuum created in a sealed tube when a column of liquid is supported by atmospheric pressure; historically, a foundational concept in fluid mechanics and the study of atmospheric pressure.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. The term is equally rare and technical in both varieties.
Connotations
Connotes a specific historical scientific achievement and the principles of pneumatics.
Frequency
Extremely low frequency in both. Almost exclusively encountered in historical scientific texts, advanced physics education, or detailed histories of science.

- Incorrect pronunciation placing stress on the first syllable (/ˈtɒrɪkɛlɪən/).
FAQ
Frequently Asked Questions
No. It contains a very low pressure of mercury vapour, making it a partial or near-perfect vacuum, but not an absolute void.
Evangelista Torricelli (1608–1647) was an Italian physicist and mathematician, a student of Galileo, who invented the barometer and proved the existence of atmospheric pressure.
Rarely. It is primarily a historical term. Modern discussions of vacuum technology use more precise, quantitative terms (e.g., low, medium, high, ultra-high vacuum).
They are essentially synonymous. 'Torricellian' specifies the historical origin and classic experimental setup, while 'barometric vacuum' is a more general descriptive term.
The vacuum created in the space above the mercury column in a barometer, as first demonstrated by Evangelista Torricelli in 1643.
Torricellian vacuum is usually academic/scientific/historical in register.
