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. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call vacuum or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object that is surrounded by a vacuum. 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. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 2. Much higher quality vacuums are possible. Ultra high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth 1. Pa, and can reach around 1. Outer space is an even higher quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average. According to modern understanding, even if all matter could be removed from a volume, it would still not be empty due to vacuum fluctuations, dark energy, transiting gamma rays, cosmic rays, neutrinos, and other phenomena in quantum physics. In the study of electromagnetism in the 1. IXL High Performance Dry Vacuum Pumps. The Blood By Benny Hinn Pdf. The iXL family of dry pumps cover the entire range of pumpdown requirements encountered in the flat panel display FPD. In modern particle physics, the vacuum state is considered the ground state of a field. Vacuum has been a frequent topic of philosophical debate since ancient Greek times, but was not studied empirically until the 1. Evangelista Torricelli produced the first laboratory vacuum in 1. Vacuum is space devoid of matter. Alaska Big Game Records'>Alaska Big Game Records. The word stems from the Latin adjective vacuus for vacant or void. An approximation to such vacuum is a region with a gaseous. At Gamma Vacuum, we have grown to be an industry leading ion pump supplier through superior quality, delivery, and service. Our products include Ion Pumps. A torricellian vacuum is created by filling a tall glass container closed at one end with mercury, and then inverting the container into a bowl to contain the mercury. Vacuum became a valuable industrial tool in the 2. The recent development of human spaceflight has raised interest in the impact of vacuum on human health, and on life forms in general. EtymologyeditThe word vacuum comes from Latinan empty space, void, noun use of neuter of vacuus, meaning empty, related to vacare, meaning be empty. Vacuum is one of the few words in the English language that contains two consecutive letters u. Historical interpretationeditHistorically, there has been much dispute over whether such a thing as a vacuum can exist. Edwards EDP Series chemical vacuum pumps offer a clean and robust pumping solution for chemical and pharmaceutical industries. Learn more here.

Ancient Greek philosophers debated the existence of a vacuum, or void, in the context of atomism, which posited void and atom as the fundamental explanatory elements of physics. Following Plato, even the abstract concept of a featureless void faced considerable skepticism it could not be apprehended by the senses, it could not, itself, provide additional explanatory power beyond the physical volume with which it was commensurate and, by definition, it was quite literally nothing at all, which cannot rightly be said to exist. Aristotle believed that no void could occur naturally, because the denser surrounding material continuum would immediately fill any incipient rarity that might give rise to a void. In his Physics, book IV, Aristotle offered numerous arguments against the void for example, that motion through a medium which offered no impediment could continue ad infinitum, there being no reason that something would come to rest anywhere in particular. Although Lucretius argued for the existence of vacuum in the first century BC and Hero of Alexandria tried unsuccessfully to create an artificial vacuum in the first century AD,8 it was European scholars such as Roger Bacon, Blasius of Parma and Walter Burley in the 1. Eventually following Stoic physics in this instance, scholars from the 1. Aristotelian perspective in favor of a supernatural void beyond the confines of the cosmos itself, a conclusion widely acknowledged by the 1. Almost two thousand years after Plato, Ren Descartes also proposed a geometrically based alternative theory of atomism, without the problematic nothingeverything dichotomy of void and atom. Although Descartes agreed with the contemporary position, that a vacuum does not occur in nature, the success of his namesake coordinate system and more implicitly, the spatialcorporeal component of his metaphysics would come to define the philosophically modern notion of empty space as a quantified extension of volume. By the ancient definition however, directional information and magnitude were conceptually distinct. With the acquiescence of Cartesian mechanical philosophy to the brute fact of action at a distance, and at length, its successful reification by force fields and ever more sophisticated geometric structure, the anachronism of empty space widened until a seething ferment1. The explanation of a clepsydra or water clock was a popular topic in the Middle Ages. Although a simple wine skin sufficed to demonstrate a partial vacuum, in principle, more advanced suction pumps had been developed in Roman Pompeii. In the medieval Middle Eastern world, the physicist and Islamic scholar, Al Farabi Alpharabius, 8. He concluded that airs volume can expand to fill available space, and he suggested that the concept of perfect vacuum was incoherent. However, according to Nader El Bizri, the physicist Ibn al Haytham Alhazen, 9. Mutazilitheologians disagreed with Aristotle and Al Farabi, and they supported the existence of a void. Using geometry, Ibn al Haytham mathematically demonstrated that place al makan is the imagined three dimensional void between the inner surfaces of a containing body. According to Ahmad Dallal, Ab Rayhn al Brn also states that there is no observable evidence that rules out the possibility of vacuum. The suction pump later appeared in Europe from the 1. Medieval thought experiments into the idea of a vacuum considered whether a vacuum was present, if only for an instant, between two flat plates when they were rapidly separated. There was much discussion of whether the air moved in quickly enough as the plates were separated, or, as Walter Burley postulated, whether a celestial agent prevented the vacuum arising. The commonly held view that nature abhorred a vacuum was called horror vacui. Speculation that even God could not create a vacuum if he wanted to was shut downclarification needed by the 1. Paris condemnations of Bishop. Etienne Tempier, which required there to be no restrictions on the powers of God, which led to the conclusion that God could create a vacuum if he so wished. Jean Buridan reported in the 1. The 1. 7th century saw the first attempts to quantify measurements of partial vacuum. Evangelista Torricellis mercurybarometer of 1. Blaise Pascals experiments both demonstrated a partial vacuum. In 1. 65. 4, Otto von Guericke invented the first vacuum pump2. Magdeburg hemispheres experiment, showing that teams of horses could not separate two hemispheres from which the air had been partially evacuated. Robert Boyle improved Guerickes design and with the help of Robert Hooke further developed vacuum pump technology. Thereafter, research into the partial vacuum lapsed until 1. August Toepler invented the Toepler Pump and Heinrich Geissler invented the mercury displacement pump in 1.
