  Bosonic string theory - Wikipedia, the free encyclopedia
Another feature of bosonic string theory is that in general the theory displays inconsistencies due to the conformal anomaly.
This high dimensionality isn't a problem for bosonic string theory because it can be formulated in such a way that along the 22 excess dimensions spacetime is folded up to form a small torus.
In the early 1970s, supersymmetry was discovered in the context of string theory, and a new version of string theory called superstring theory (supersymmetric string theory) became the real focus.

 Theory Flux
Unfortunately, the usage of the term theory is muddled by cases such as string theory and various theories of everything, all of which are better characterized at present as a bundle of competing hypotheses for a protoscience.
In the humanities, theory is often used as an abbreviation for critical theory or literary theory, referring to continental philosophy's aesthetics or its attempts to understand the structure of society and to conceptualize alternatives.
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.

 Two cheers for string theory | Cosmic Variance
String theory, with all of its difficulties, is by far the most promising route to one of the most long-lasting and ambitious goals of natural science: a complete understanding of the microscopic laws of nature.
String theorists, arrogant as they are, ignored all of that and claimed that all of chemistry was an application of string theory.
String theory fails to provide any mechanism to generate the very small nonzero masses that are observed in nature, or to remove the exact spacetime supersymmetry, which is not observed in nature.

 Luboš Motl's reference frame
Physicists have known for two decades that the perturbative definition of string theory is not enough to understand various subtle issues that are important for the comparison with experiments - or for internal conceptual questions of the theory such as the vacuum selection problem.
Strings only look like "elementary" objects at weak coupling because they're the lightest objects, but at stronger coupling, a new kind of democracy between the strings and other objects such as branes emerges.
We should always consider the most general theory that respects the same symmetries and other principles and is equally consistent as the first idea in the class of theories that we have encountered, discovered, or invented.

 String Theory and Spirituality
String theory, also called superstring theory, is a fast-growing discovery in the field of physics.

Many philosophers and scientists, discussing the spiritual implications of string theory, suggest that Deity is the source of the vibrations of the universe.

 Not Even Wrong
This is the same kind of foolishness as the comment that “physicists may have to rethink what it means for a theory to explain experimental data” because of string theory (see here).
He begins with an historical analogy, comparing the present state of string theory to that of quantum mechanics in the period 1913-1926, and the Bohr model of the hydrogen atom to N=4 supersymmetric YM and AdS/CFT.
One topic is an abstract proposal for a metric on the “space of all CFTs”, the other is the classification of D-branes on a Calabi-Yau in terms of a derived category.

This is the ultimate reason that the Torah chooses the "perfect" number system to be the decimal system (as is said in the Torah: "The tenth shall be holy for God").
The letter yud is the first letter of God's essential Name Havayah (whose full value equals 26, the sole other possible number of dimensions of the universe according to string theory).
The "female" principle of reality is "revelation" whereas the "male" principle is concealed within the "female." So is the relation, according to string theory, of the 6 concealed dimensions of reality to the 4 revealed dimensions.

This list grew quite rapidly as others contributed, and it now includes many naturally occuring problems which cannot yet be solved in polynomial time.
A language L' is polynomial time reducible to a language L if there exists a polynomial time function f(x) from strings to strings such that x is in L' if f(x) is in L.
This means that if we can test strings for membership in L in time t, we can use f to test strings for membership in L' in a time polynomial in t.

 Kabbalah and String Theory
ne of the most recent theories in physics--able, in theory, to unify the four known forces of nature (and thereby achieve a "unified field theory") but as of yet unable to be validated by experiment--is "string theory." Its basic concepts and images bring to mind most evident correlations to the teachings of traditional Jewish Kabbalah.
We will here touch upon three basic concepts: Ten dimensions; the string; four forces from one.
