String (physics) - Types of Strings - Closed and Open Strings
... Strings can be either open or closed ... A closed string is a string that has no end-points, and therefore is topologically equivalent to a circle ... An open string, on the other hand, has two end-points and is topologically equivalent to a line interval ...

Type I String Theory
... In theoretical physics, type I string theory is one of five consistent supersymmetric string theories in ten dimensions ... It is the only one whose strings are unoriented (both orientations of a string are equivalent) and which contains not only closed strings, but also open strings ... understanding of the rules behind string spectra in cases where only closed strings are present via modular invariance but did not lead to similar progress for models with closed strings ...

Famous quotes containing the words strings and/or closed:
“Until, accustomed to disappointments, you can let yourself rule and be ruled by these strings or emanations that connect everything together, you haven’t fully exorcised the demon of doubt that sets you in motion like a rocking horse that cannot stop rocking.”
—John Ashbery (b. 1927)
“Night hath closed all in her cloak,
Twinkling stars love-thoughts provoke,
Danger hence good care doth keep,
Jealousy itself doth sleep;”
—Sir Philip Sidney (1554–1586)
