What Is String Theory?Sen, Ashoke
String theory is the idea in theoretical physics that reality is made up of infinitesimal vibrating strings, smaller than atoms, electrons or quarks. According to this theory, as the strings vibrate, twist and fold, they produce effects in many, tiny dimensions that humans interpret as everythin...
“Fluctuating Geome-tries in Statistical Mechanics and Field Theory.” The first part is an introductionto conformal field theory and string perturbation theory. The second part dealswith the search for a deeper answer to the question posed in the title.1Electronic address: joep@sbitp.itp.ucsb....
The basic concept in string theory concerns tiny elementary particles. Normally, when you hearparticle,you think of a dot, like a point in space or the period at the end of the sentence. But in string theory, instead of a dot, a particle is seen instead as a tiny vibrating string that...
What presents theString theory? Quantum physics: Quantum mechanics can basically be thought of as a set of laws that are used to predict the behaviour of very tiny particles.Quantum mechanics can basically be thought of as a set of laws that are used to predict the behaviour of very tiny ...

String theory and number theory have common ground in a specific kind of elliptic curve from a torus. Toruses aren't just for compressing atoms: these curves represent torus cross-sections. The secret to the link is in modularity and invariance in the equations representing the curves.Scientists...
NASA's Chandra X-ray Observatory helped power an experiment that might refute string theory. What now?
There are links to the laws of physics too. String theory, known as "the theory of everything," which emerged from the work of numerous physicists, suggests that the building blocks of the universe are not particles but incredibly tiny strings. ...
So back to the point particle case, theψ(x)ψ(x)is a complex number assigned to the positionxx. So you can confuse it with, or think of it as, a function on physical space, even though it is a function on the possible results of measuring the position. In the case of a two pa...
