		The pattern is the result of the interference of two waves to produce these nodes and anti-nodes.) In this pattern, there is only one-half of a wave within the length of the string.
		The third harmonic of a guitar string is produced by adding two nodes between the ends of the guitar string.
		In order to create a regular and repeating pattern for this harmonic, the two additional nodes must be evenly spaced between the ends of the guitar string; this places them at the one-third mark and the two-thirds mark along the string.

	Quantum Gravity Theories - Physics Help and Math Help - Physics Forums
		Furthermore string theories only seem to work in a\nuniverse that is "super symmetric" and no experimental proof exist to back\nup any of it\'s claims.\n\nLoop quantum gravity and other so called canonical theories of quantum\ngravity are more like general relativity in that they look at gravity as\nbeing a consequence of the geometry of space time.
		In the view of string theory it is the action\nof theses stringgy gravitons which gives rise to gravity.\n\n* The reason that string theory has not been universally accepted as the\ntheory of everything including quantum gravity is that there is more than\none string theory.
		In string theory the background\nspace time is fixed and (usually) flat and has 11 or more dimensions.\nforces, fields and particles are all represented by vibrational modes of\nthe strings.

	Theoretical Elementary Particle Physics - Chicago
		The Particle Theory Group at the University of Chicago, part of the Enrico Fermi Institute, carries out research on a wide range of theoretical topics in formal and phenomenological particle physics, including field theory, string theory, supersymmetry, the standard model, cosmology, and mathematical physics.
		Two of the most relevant open questions in particle physics are the ones related to the origin of mass and to the existence of a unified theory of all known elementary particle interactions.
		With string theory, and with field theories on non-commutative spaces, there are now more explicit models, and we are studying their implications.

	Super G-String Field Theory (figures to appear)
		This includes anybody who still calls strings "dual models".) The super G-string can also be used to derive models of GUTS [5] cosmetology (gastronomy), through the use of string solitons known as "comic strings" [6], due to their comic proportions.
		All these results can be derived from a very general formalism which encompasses particle physics as well as string physics.
		As for all high-energy physics, all string physics (not to be confused with the old-fashioned topic of particle physics) can be classified into two types: (1) esthetic and (2) anesthetic.

	The Thin Line of Theory - The Daily Free Press - Science
		Strings All Around Us While the focus of research in high energy physics at BU is not directed toward string theory, Cohen said, there have been occasions when BU faculty have done work in the area.
		Although string theory is not grounded in empirical data, Vafa said, it has already greatly influenced the way we think about physics and that perhaps 15 years ago BU could have afforded not to give substantial attention to string theory.
		Glashow cautioned that particle theory, under which string theory and phenomenology fall, comprises only a small fragment of any physics department.

	AllRefer.com - centripetal force and centrifugal force (Physics) - Encyclopedia
		Thus, in twirling a mass on a string, the centripetal force transmitted by the string pulls in on the mass to keep it in its circular path, while the centrifugal force transmitted by the string pulls outward on its point of attachment at the center of the path.
		For a planet orbiting the sun, the force is gravitational; for an object twirled on a string, the force is mechanical; for an electron orbiting an atom, it is electrical.
		The centrifugal force is often mistakenly thought to cause a body to fly out of its circular path when it is released; rather, it is the removal of the centripetal force that allows the body to travel in a straight line as required by Newton's first law.

		Copyright 2001 by the Department of Physics at the University of Illinois at Urbana-Champaign.
		The study of D-branes is fundamental to modern string theory and, in particular, to string duality, where the strong coupling limit of one string is related to the weak coupling limit of another.
		Professor Rob Leigh received his bachelor's degree in Theoretical Physics from the University of Guelph in 1986 and his Ph.D. in Theoretical Particle Physics, from the University of Texas at Austin in 1991.

	Theoretical Physics
		The main area of interest is the derivation of properties of low energy supergravity that may have a bearing on particle physics at accelerator energies from compactifications of heterotic string theories.
		In the low energy limit (compared to the string scale) the string theory reduces to an effective N = 1 supergravity theory and it is possible in principle to derive information from the string theory concerning parameters which would otherwise be free parameters of the supergravity theory.
		Of these, orbifold compactification, ie compactification on a torus with points identified by a discrete group, is perhaps the best developed.

	Sum Over Histories Quantum Chaos Riemann Zeta Function
		The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3x3 Octonionic matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the following physical interpretation: 4-dimensional physical spacetime plus 4-dimensional internal symmetry space; 8 first-generation fermion particles; 8 first-generation fermion anti-particles.
		More precisely, we believe that bosonic string theory is the compactification on a line interval of a 27 dimensional theory whose low energy limit contains gravity and a three-form potential.
		As an aside, we note that there is also a brane solution of 26 dimensional bosonic string theory which has both electric and magnetic charge associated with the three-form H. It is a 21-brane with fundamental strings lying in it and smeared over the remaining 20 directions.

	String theory - Wikipedia, the free encyclopedia
		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.
		String theory as a whole has not yet made falsifiable predictions that would allow it to be experimentally tested, though various special corners of the theory are accessible to planned observations and experiments.
		String theory was originally invented to explain peculiarities of hadron (subatomic particle which experiences the strong nuclear force) behavior.

		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.
		Since string theory may not be tested in the foreseeable future, some scientists have asked if it even deserves to be called a scientific theory: it is not yet a falsifiable theory in the sense of Popper.
		Originally discussed in the 1980s, cosmic strings are a different type of object than the entities of superstring theories.
