what is glass field theory?
605419
The most coherent description I could find was at wikipedia under "spin glass". It's about the time-dependent magnetic characteristic of certain materials that can enter a spin glass phase above a critical temperature. Mean field theory (click the link to this on the referenced page) has been used in theorizing on these dynamics.

Awesome question.  I have no idea.  The first thing you would have to know is what the properites of glass are that could, if at all, slow the speed of light.  As well as at what thickness of glass, which, in a backwards loop hole sortof way, directly relates to my last sentance.  (if a piece of glass were doubly thick as a single piece of glass, would it cut the speed of light in half?--depends on how thick the original piece was and if the original piece did anything to slow light's speed at all--see where i'm goin?).  Please tell me what you find, I'm very curious, I love questions that make me think deep.  Peace out dude, rioedgebravo@yahoo.com

String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects (strings) rather than the zero-dimensional points (particles) that are the basis of the Standard Model of particle physics. For this reason, string theories are able to avoid problems associated with the presence of pointlike particles in a physical theory. Studies of string theories have revealed that they require not just strings but also higher-dimensional objects.

it is RAYLEIGHS THEORY

According to one theory there are particles, which are exchanged and travel between the objects, giving impression that objects attract or repel each other. Nothing is proved yet and it is just a theory, as far as my knowledge is concerned.

This question has been beaten to death here.  Proponents of the "glass is a liquid" theory point to old window glass which seems to have become thicker on one edge.  This is simply urban legend, perpetuated by teachers who don't know any better.  \n\nIF a material with the extremely high viscosity of glass flowed, then the materials holding the glass in the frame (lead, in the case of stained glass windows in old cathedrals) would also have flowed, but much more, since they have much lower viscosity - and this just hasn't happened.  The glass is simply thicker in some parts due to the manufacturing process used.\n\nAnd glass is NOT a supercooled liquid; although it doesn't exhibit a first order phase transition, it DOES exhibit a second order transition between the supercooled liquid state and the glass state.\n\nBy definition, glass is an amorphous solid.\n\n1.   "A glass is an amorphous solid which exhibits a glass transition"\n2. "A solid is a material whose shear viscosity exceeds 10^14.6 poise" \n\nEstimates of the viscosity of glasses at room temperature run as high as 10 to the 20th power.\n\nAnd my favorite debunking page: http://tafkac.org/science/glass.flow/amorphous_solid_more.html

It is sometimes said that glass in very old churches is thicker at the bottom than at the top because glass is a liquid, and so over several centuries it has flowed towards the bottom.  This is not true.  In Mediaeval times panes of glass were often made by the Crown glass process.  A lump of molten glass was rolled, blown, expanded, flattened and finally spun into a disc before being cut into panes.  The sheets were thicker towards the edge of the disc and were usually installed with the heavier side at the bottom.  Other techniques of forming glass panes have been used but it is only the relatively recent float glass processes which have produced good quality flat sheets of glass.\n\nTo answer the question "Is glass liquid or solid?" we have to understand its thermodynamic and material properties.\n\nThermodynamics of glass\n\nThere is still much about the molecular physics and thermodynamics of glass that is not well understood, but we can give a general account of what is thought to be the case.\n\nMany solids have a crystalline structure on microscopic scales.  The molecules are arranged in a regular lattice.  As the solid is heated the molecules vibrate about their position in the lattice until, at the melting point, the crystal breaks down and the molecules start to flow.  There is a sharp distinction between the solid and the liquid state, that is separated by a first order phase transition, i.e. a discontinuous change in the properties of the material such as density.  Freezing is marked by a release of heat known as the heat of fusion. \n...\nConclusion\n\nThere is no clear answer to the question "Is glass solid or liquid?".  In terms of molecular dynamics and thermodynamics it is possible to justify various different views that it is a highly viscous liquid, an amorphous solid, or simply that glass is another state of matter which is neither liquid nor solid.  The difference is semantic.  In terms of its material properties we can do little better.  There is no clear definition of the distinction between solids and highly viscous liquids.  All such phases or states of matter are idealisations of real material properties.  Nevertheless, from a more common sense point of view, glass should be considered a solid since it is rigid according to every day experience.  The use of the term "supercooled liquid" to describe glass still persists, but is considered by many to be an unfortunate misnomer that should be avoided.  In any case, claims that glass panes in old windows have deformed due to glass flow have never been substantiated.  Examples of Roman glassware and calculations based on measurements of glass visco-properties indicate that these claims cannot be true.  The observed features are more easily explained as a result of the imperfect methods used to make glass window panes before the float glass process was invented.

The universal field theory is still being attempted. You see the field theory which governs large things like planets doesn't cover things which are small. By small we are talking molecular. You see when Hawking first realized that black holes aren't persistant and that they do burn out he realized that the particles within them must act differently that those of larger size (planets) and now he and some others are trying to prove a universal field theory that covers all of them. \n\nThat's about as simple as I can make it man without filling page after page.

Well, probably easier to explain empirically -- I know that one of the equations that you would be looking for is Planck's law of black-body radiation.  That, along with other equations involved in transport phenomena could be used to model the system and let you know how much heat you lose from the glass.\n\nOff the top of my head, I can't remember every equation that one would want to use.  Good luck!\n\nThe link is to Wiki's entry for Transport Phenomena -- the first reference there would be an excellent -- if very heavy on the math -- reference for solving this problem.

Yes, Richard Feynman suggested this way back when. \n\nThe original paper is available here: http://prola.aps.org/abstract/PR/v76/i6/p749_1\n\nWithout a subscription you'll only be able to read the abstract.

It cant be just any piece of glass, it has to be a prism. The light comes out in the form of a rainbow because the prism separates the light into it's visible colors.

No, it is not.  Also, if you've heard that glass "flows" over time, you've been misinformed.\n\nhttp://www.glassnotes.com/WindowPanes.html

its not really a theory.  its more scientific fact.\n\ncollapse of the entire world economy is the theory part

If we put two smooth glasses together (without glue them), normally what is the distance in between? \nIn an ideal situation, let's say the two glass surfaces are perfectly smooth and 100% flat, and we superpose one of them onto the other, there should be an uniform distributed air-layer between the two pieces of glasses even though it looks we put them in direct contact, so what is the thickness of this air strip? round 10nm? or more than 1 μm?\nAny guess is welcomed :)\n\n\nif ur mentioning that it is an ideal situation - glass 100% smooth etc. then it is stupid of u to ask such a question. \n\nThere wud b no air gap b/w them.\n\n(ur quest included so u may not modify it later)\n\n\nArchitectural glass is made from three principal raw materials, easily found in nature: silica, lime and sodium carbonate.\nAvg size of molecular terrain would be approximately 300 - 3000A. (neglecting secondary composition of glass). Thus logically this has to be the thickness of this strip of air.
