{{Weasel}}
The Greek [[philosopher]] [[Aristotle]] ([[384 BC]] – [[322 BC]]) developed many '''theories on the nature of [[physics]]''' that are completely different from what are now understood as the [[laws of physics]]. These involved what Aristotle described as the [[Classical element|four elements]], as well as a variety of principles, most of which modern science has now disproved, and which provide no significant roots to any area of modern physics.


<!-- Commented out: [[Image:DSCN0585.JPG|right|thumb|300px|Picture of a Dell-branded Sony Trinitron, still bearing the Trinitron logo.]] -->
He spoke intimately of the relation between these elements, of their dynamics, and how they impacted on the earth, and were, in many cases, attracted to each other by unspecified forces. He also taught miscellaneous other aspects of his physics model, including his widely believed theory relating to moving energy.
'''Trinitron''' is [[Sony]]'s [[brand name]] for its line of [[aperture grille]] [[cathode ray tube]] [[television]]s and [[computer display|computer monitors]]. Sony patented the design, which was invented by E.O Lawrence at Autometric Laboratory, and called "Chromatron", in the 1960s and held the [[patent]] until 1996{{Fact|date=February 2007}}. See pg 42-48 of "SONY" by John Nathan for more info on the birth of Trinitron.


The name Trinitron was derived from ''[[Trinity (disambiguation)|trinity]]'', meaning the union of three, and ''tron'' from [[electron]] tube.<ref>[http://www.sony.net/Fun/SH/1-12/h7.html "You Guys Can Do It!"] - Sony Global - Sony History</ref>
== Aristotelian physics ==
Aristotle taught that the [[classical element|elements]] that composed the [[Earth]] were different from those that made up the heavens and [[Outer space]].<ref name="utk">{{Cite web|url=http://csep10.phys.utk.edu/astr161/lect/history/aristotle_dynamics.html|title=Physics of Aristotel vs. The Physics of Galileo|accessmonthday=26 March|accessyear=2007}}</ref>
He also taught that [[dynamics]] were mostly determined by the characteristics and nature of the [[substance]]s that the object that was moving was composed of.<ref name="utk" />


=== Elements ===
==Chronology==
"Trinitron" is sometimes used as a generic term for CRT monitors equipped with an aperture grille tube. After the expiration of Sony's Trinitron patent, manufacturers like [[Mitsubishi Electric|Mitsubishi]] (whose monitor production is now part of [[NEC Display Solutions]]) are free to use the Trinitron design for their own product line without license from Sony although they cannot use the Trinitron name; for example, Mitsubishi's are called ''Diamondtron''.
Aristotle believed that there were four main [[classical element|elements]] or [[compounds]] that made up the [[Earth]]: [[earth (classical element)|earth]], [[air (classical element)|air]], [[water (classical element)|water]] and [[fire (classical element)|fire]].{{Ref_label|A|a|none}}<ref name="edu">{{Cite web|url=http://www.hep.fsu.edu/~wahl/Quarknet/pepperlect/aristogalnewt.pdf|title=www.hep.fsu.edu|accessmonthday=26 March|accessyear=2007}}</ref>
He also held that all the heavens, and every particle of [[matter]] in the [[universe]], was formed out of another, fifth element he called '[[aether]]' (also transliterated as "ether")<ref name="edu" />, which was supposedly weightless and "incorruptible".<ref name="edu" /> Aether was also known by the name 'quintessence' - literally, "fifth substance".<ref name="ari">{{Cite web|url=http://aether.lbl.gov/www/classes/p10/aristotle-physics.html|title=Aristotel's physics|accessmonthday=27 March|accessyear=2007}}</ref>
[[Image:Aristotle Physica page 1.png|thumb|left|200px|Page taken from the 1837 edition of Aristotle's ''Physics'', a book written about a variety of subjects including philosophy and physics]]


Trinitron televisions were regarded as the best available in terms of picture quality and were therefore more expensive than the equivalent [[shadow mask]] CRT screens. Trinitron designs provide vivid colors and high contrast with good across-the-screen electron focus. However, with the emergence of [[Plasma display|gas plasma]], [[liquid crystal display]] and other display technologies Trinitron and similar brands have been in decline. The remaining advantages of the Trinitron are a wide colour palette and dot pitch comparable to LCD and plasma screens. This ensures their continuing popularity in graphic design applications.
Heavy substances such as [[iron]] and metals were considered to be primarily consisting of the "element" of earth, with a limited amount of [[matter]] from the other elements. Other, less heavy and/or dense objects were thought to be less earthy, and composed of a greater mixture of the other elements.<ref name="ari" />
[[Human]]s were shaped with all of the substances, with the exception of ether, but the relative proportion of elements was unique to each person, and there was no standard amount of each within the human body.<ref name="ari" />


At the time of their introduction in the early 1950s, color CRTs included complicated dynamic convergence systems which were responsible for merging the three electron beams onto one triad of phosphors. Part of the revolutionary nature of the Trinitron's design was the virtual elimination of dynamic convergence circuits, replacing them with bonded permanent magnets on the bell of the tube. Another feature was a three cathode single electron gun arrangement, in contrast to the then-dominant (and still common) three gun arrangement. Single gun systems are easier to manufacture reliably, simplify beam focus and control, and are less prone to inter-electrode short circuits.
=== Dynamics ===


As a result, in the mid 1980s [[Eizo]] became well known as a successful manufacturer of CRT based computer monitors due to their use of grading; the company picked only the best performing and most consistent Trinitron tubes from the Sony production line for use in their products. Sony Trinitron computer monitors have also been rebranded and distributed by [[Apple Inc.]], [[Dell, Inc.|Dell]], [[Digital Equipment Corporation]], [[Mitsubishi]], [[Gateway 2000|Gateway]], [[IBM]], [[Silicon Graphics]], [[Sun Microsystems]] and others. The monitors have an identical chassis to the Sony-branded counterparts, and most bear the silver "Trinitron" logo upon the top-left corner of the bezel.
Aristotle held that each of the four worldly elements would each seek each other and cluster together, and that this seeking of other similar elements would have to be hindered to be stopped, as it was as natural as two [[magnet]]s rejecting each other, or rain falling from the clouds. For instance, because [[smoke]] was mainly air, it would rise to meet the air in the sky. He also taught that objects and matter could only move so long as a form of [[energy]] was forcing it in a given direction.<ref name="utk2">{{Cite web|url=http://csep10.phys.utk.edu/astr161/lect/history/aristotle_dynamics.html|title=Physics of Aristotle vs. The Physics of Galileo|accessmonthday=28 March|accessyear=2007}}</ref> Therefore, if all the applied forces on Earth were removed, such as the throwing of a rock, then nothing could move.<ref name="utk2">{{Cite web|url=http://csep10.phys.utk.edu/astr161/lect/history/aristotle_dynamics.html|title=Physics of Aristotle vs. The Physics of Galileo|accessmonthday=28 March|accessyear=2007}}</ref> This idea had flaws that were visible even at the time the concept was formulated. Many people questioned how an object such as an [[arrow]] could continue to move forward after it had left the power released by the string, and continue to sail forward. Aristotle proposed an idea that arrows, etc., created a type of [[vacuum]] behind them that forced them forward.<ref name="utk2" />, which was consistent with his interpretation of motion as an interaction of the moving object and the medium through which it moves. Since the turbulent motion of air around an arrow is very complicated, and still not fully understood, any discrepancy with observation could be swept under the rug.


Sony's final update to the technology was the [[FD_Trinitron_WEGA|FD]] Flat Display in the Wega&trade; product line.
Because Aristotle placed the medium at the center of his theory of motion, he could not make sense of the notion of a void central to the atomic theory of [[Democritus]]. A void is a place free of anything, and since Aristotle asserted that motion required a medium, he came to the conclusion that a void was an incomprehensible idea. Aristotle's believed that the motion of an object is inversely proportional to the density of the medium. the more tenuous a medium is, the faster the motion. If an object is moving in void, Aristotle believed that it would be moving infinitely fast, so that matter would instantly fill up any void at the moment it formed.<ref>Land, Helen ''The Order of Nature in Aristotle's Physics: Place and the Elements'' (1998)</ref>


In 2007, Sony announced that it would no longer market or sell Trinitrons in the USA or Canada, but currently continue to sell the Trinitron in China, India, and regions of South America.
=== Gravity ===


==Visible Support Wires==
The '''Aristotelian theory of gravity''' was a theory that stated that all bodies move towards their natural place. For some objects, [[Aristotle]] claimed the natural place to be the center of the [[earth]], wherefore they fall towards it. For other objects, the natural place is the heavenly spheres, wherefore gases, steam for example, move away from the centre of the earth and towards heaven and to the [[moon]]. The [[speed]] of this [[Motion (physics)|motion]] was thought to be proportional to the [[mass]] of the object.


Monitors using this technology have one or more thin, obviously visible horizontal wires used to hold the aperture grille in place over the electron gun. Displays of 15" and below have one wire two thirds of the way down the screen. Monitors greater than 15" have 2 horizontal wires; the first between one quarter and one third of the way down and the second between two thirds and three quarters of the way down the screen. These wires are in similar positions on television screens using the Trinitron format. This is a minor drawback of the Trinitron standard which is not shared by similar shadow mask CRTs.
==Medieval criticisms==

==Partial list of other aperture grille brands==
During the [[Middle Ages]], the Aristotelian theory of gravity was first criticized and/or modified by [[John Philoponus]] and later by [[Islamic physics|Muslim physicists]]. [[Ja'far Muhammad ibn Mūsā ibn Shākir]] (800-873) of the [[Banū Mūsā]] wrote the ''Astral Motion'' and ''The Force of Attraction'', where he discovered that there was a [[force]] of [[Gravitation|attraction]] between [[Astronomical object|heavenly bodies]],<ref>K.

==End of Production Announcement==
[[Ibn al-Haytham]] (965-1039) also discussed the theory of attraction between [[mass]]es, and it seems that he was aware of the [[Magnitude (mathematics)|magnitude]] of [[acceleration]] due to [[gravity]] and he discovered that the heavenly bodies "were accountable to the [[Physical law|laws of physics]]".<ref>Duhem, Pierre (1908, 1969).

Sony has completed production of all Trinitron CRT models at its Singapore manufacturing plant. Trinitron CRT production ceased in Japan at the end of March 2008. Sony removed all Trinitron CRT models from the Japanese product catalogue [[as of 2006]].


Sony's estimated production of Trinitron screens is greater than 280 million units (incl. computer peripherals) since the Trinitron technology began shipping in 1968. The sales peaked at the turn of the 21st century with sale of more than 11 million units [[as of 2000]]. The yearly sales figure steadily declined to 2.8 million units [[as of 2007]]. Sony has subsequently shifted focus to the manufacture of LCD and EL based models; these can be considered successors.

In the 14th century, [[Jean Buridan]] developed the [[theory of impetus]], based on [[Avicenna]]'s theory of ''mayl'' and the work of [[John Philoponus]], as an alternative to the Aristotelian theory of motion. The theory of impetus was a precursor to the concepts of [[inertia]] and [[momentum]] in classical mechanics.

In the 16th century, [[al-Birjandi]] discussed the possibility of the [[Earth's rotation]]. In his analysis of what might occur if the Earth were rotating, he developed a hypothesis similar to [[Galileo Galilei]]'s notion of "circular [[inertia]]",<ref>{{Harv|Ragep|2001b|pp=63-4}}</ref> which he described in the following [[Experiment|observational test]]:

{{quote|"The small or large rock will fall to the Earth along the path of a line that is perpendicular to the plane (''sath'') of the horizon; this is witnessed by experience (''tajriba''). And this perpendicular is away from the tangent point of the Earth’s sphere and the plane of the perceived (''hissi'') horizon. This point moves with the motion of the Earth and thus there will be no difference in place of fall of the two rocks."<ref>{{Harv|Ragep|2001a|pp=152-3}}</ref>}}

== Life and death of Aristotelian physics ==

The reign of Aristotelian notions of physics lasted for almost two millennia, and provide the earliest known speculative theories of physics. After the work of [[Ibn al-Haytham|Alhacen]], [[Avicenna]], [[Ibn Bajjah|Avempace]], [[Hibat Allah Abu'l-Barakat al-Baghdaadi|al-Baghdadi]], [[Jean Buridan]], [[Galileo]], [[Descartes]], [[Isaac Newton]], and many others, it became generally accepted that Aristotelian physics were not correct or viable.<ref name="ari2">{{Cite web|url=http://aether.lbl.gov/www/classes/p10/aristotle-physics.html|title=Aristotel's physics|accessmonthday=28 March|accessyear=2007}}</ref>
Despite this, Aristotle's physics were able to live into the late [[seventeenth century]], and perhaps longer, as they were still taught in universities at the time. Aristotle's model of physics was the main academic impediment for the creation of the science of physics long after Aristotle's death.

In [[Europe]], [[Aristotle]]'s theory was first convincingly discredited by the work of [[Galileo Galilei]]. Using a [[telescope]], Galileo observed that the moon was not entirely smooth, but had craters and mountains, contradicting the Aristotelian idea of an incorruptible perfectly smooth moon. Galileo also criticized this notion theoretically &ndash; a perfectly smooth moon would reflect light unevenly like a shiny billiard ball, so that the edges of the moon's disk would have a different brightness than the point where a tangent plane reflects sunlight directly to the eye. A rough moon reflects in all directions equally, leading to a disk of approximately equal brightness which is what is observed <ref> Galileo Galilei ''Dialog On the Two Principle Systems of the World''</ref>. Galileo also observed that [[Jupiter]] has [[Galilean moons|moons]], objects which revolve around a body other than the Earth. He noted the [[phases]] of Venus, convincingly demonstrating that Venus, and by implication Mercury, travels around the sun, not the Earth.

According to legend, Galileo dropped balls of various [[Density|densities]] from the [[Leaning Tower of Pisa|Tower of Pisa]] and found that lighter and heavier ones fell at almost the same speed. In fact, he did quantitative experiments with balls rolling down an inclined plane, a form of falling that is slow enough to be measured without advanced instruments.

Since Aristotle did not believe that motion could be described without a surrounding medium, he couldn't treat [[air resistance]] as a complicating factor. A heavier body falls faster than a lighter one of the same shape in a dense medium like water, and this led Aristotle to speculate that the rate of falling is proportional to the mass and inversely proportional to the density of the medium. From his experience with objects falling in water, he concluded that water is approximately ten times denser than air. By weighing a volume of compressed air, Galileo showed that this overestimates the density of air by a factor of forty<ref> Galileo Galilei ''Two New Sciences''</ref>. From his experiments with inclined planes, he concluded that all bodies fall at the same rate neglecting friction.

Galileo also advanced a theoretical argument to support his conclusion. He asked if two bodies of different masses and different rates of fall are tied by a string, does the combined system fall faster because it is now more massive, or does the lighter body in its slower fall hold back the heavier body? The only convincing answer is neither: all the systems fall at the same rate<ref> Galileo ''Dialog Concerning the Two Principal Systems of the World''</ref>.

Followers of Aristotle were aware that the motion of falling bodies was not uniform, but picked up speed with time. Since time is an abstract quantity, the [[peripatetic]]s postulated that the speed was proportional to the distance. Galileo established experimentally that the speed is proportional to the time, but he also gave a theoretical argument that the speed could not possibly be proportional to the distance. In modern terms, if the rate of fall is proportional to the distance, the differential equation for the distance y travelled after time t is
:<math>
{dy\over dt} = y
</math>
with the condition that <math>y(0)=0</math>. Galileo demonstrated that this system would stay at <math>y=0</math> for all time. If a perturbation set the system into motion somehow, the object would pick up speed exponentially in time, not quadratically <ref> Galileo ''Two New Sciences''</ref>.

On the surface of the [[moon]], [[David Scott]] famously repeated Galileo's experiment by dropping a feather and a hammer from each hand at the same time. In the absence of a substantial [[atmosphere]], the two objects fell and hit the moon's surface at the same time.

With his [[Newton's law of universal gravitation|law of universal gravitation]] [[Isaac Newton]] was the first to mathematically codify a correct theory of gravity. In this theory, any mass is attracted to any other mass by a force which decreases as the inverse square of their distance. In 1915, Newton's theory was modified, but not invalidated, by [[Albert Einstein]], who developed a new picture of [[gravitation]], in the framework of his [[General relativity|general theory of relativity]]. See ''[[gravity]]'' for a much more detailed complete discussion.

Revision as of 05:57, 11 October 2008

Trinitron is Sony's brand name for its line of aperture grille cathode ray tube televisions and computer monitors. Sony patented the design, which was invented by E.O Lawrence at Autometric Laboratory, and called "Chromatron", in the 1960s and held the patent until 1996[citation needed]. See pg 42-48 of "SONY" by John Nathan for more info on the birth of Trinitron.

The name Trinitron was derived from trinity, meaning the union of three, and tron from electron tube.[1]

Chronology

"Trinitron" is sometimes used as a generic term for CRT monitors equipped with an aperture grille tube. After the expiration of Sony's Trinitron patent, manufacturers like Mitsubishi (whose monitor production is now part of NEC Display Solutions) are free to use the Trinitron design for their own product line without license from Sony although they cannot use the Trinitron name; for example, Mitsubishi's are called Diamondtron.

Trinitron televisions were regarded as the best available in terms of picture quality and were therefore more expensive than the equivalent shadow mask CRT screens. Trinitron designs provide vivid colors and high contrast with good across-the-screen electron focus. However, with the emergence of gas plasma, liquid crystal display and other display technologies Trinitron and similar brands have been in decline. The remaining advantages of the Trinitron are a wide colour palette and dot pitch comparable to LCD and plasma screens. This ensures their continuing popularity in graphic design applications.

At the time of their introduction in the early 1950s, color CRTs included complicated dynamic convergence systems which were responsible for merging the three electron beams onto one triad of phosphors. Part of the revolutionary nature of the Trinitron's design was the virtual elimination of dynamic convergence circuits, replacing them with bonded permanent magnets on the bell of the tube. Another feature was a three cathode single electron gun arrangement, in contrast to the then-dominant (and still common) three gun arrangement. Single gun systems are easier to manufacture reliably, simplify beam focus and control, and are less prone to inter-electrode short circuits.

As a result, in the mid 1980s Eizo became well known as a successful manufacturer of CRT based computer monitors due to their use of grading; the company picked only the best performing and most consistent Trinitron tubes from the Sony production line for use in their products. Sony Trinitron computer monitors have also been rebranded and distributed by Apple Inc., Dell, Digital Equipment Corporation, Mitsubishi, Gateway, IBM, Silicon Graphics, Sun Microsystems and others. The monitors have an identical chassis to the Sony-branded counterparts, and most bear the silver "Trinitron" logo upon the top-left corner of the bezel.

Sony's final update to the technology was the FD Flat Display in the Wega™ product line.

In 2007, Sony announced that it would no longer market or sell Trinitrons in the USA or Canada, but currently continue to sell the Trinitron in China, India, and regions of South America.
