Vacuum Physics and Technology, Volume 14
A vacuum is space devoid of matter. The word stems from the Latin adjective vacuus for "vacant" or " void ". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. Vacuum has been a frequent topic of philosophical debate since ancient Greek times, but was not studied empirically until the 17th century.
