The History of String Theory: Debates and Discoveries in the 1960s

Click For Summary

Discussion Overview

The discussion centers on the historical development of string theory, particularly its origins in the 1960s. Participants explore various contributions to string theory, including key figures and their findings, as well as the theoretical implications of these developments.

Discussion Character

  • Historical, Debate/contested

Main Points Raised

  • Some participants recall that string theory first emerged around 1968, with debates surrounding its connection to Euler's equations and their implications for the strong and weak forces.
  • One participant mentions Gabriele Veneziano's role in the initial discovery of string theory and references Brian Greene's "The Elegant Universe" for further context.
  • Another participant outlines the evolution of string theory, highlighting contributions from Michael Green, John Schwarz, Yoichiro Nambu, Holger Nielsen, and Leonard Susskind, culminating in the development of superstring theory in 1984.
  • Details are provided about the nature of strings, their dimensions, and the concept of supersymmetry as an attempt to unify fundamental forces, though it is noted that the correctness of string theory remains uncertain.
  • One participant suggests a resource for a capsule history of string theory, mentioning Patricia Schwartz's website as a source of information.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the exact timeline and details of string theory's origins, indicating that multiple competing views and interpretations exist without a clear consensus.

Contextual Notes

Some statements rely on specific interpretations of historical events and contributions, which may vary among participants. The discussion does not resolve the complexities surrounding the development and acceptance of string theory.

I was just trying to remember didn't String theory first come up in like 1968 when it was debated whether someone found something from oilers equations that happened to describe the strong and weak force? Or was that when it was making its first comeback... ah I can't remember.

Just trying to figure out how string theory was started.

See Gabriele Veneziano (page 136 of Brian Greene's The Elegant Universe) and even Susskind's contribution

Michael Green and John Schwarz continued development of string theory – discovered in 1968 by Gabriele Veneziano and improved on in 1970 by Yoichiro Nambu, Holger Nielsen and Leonard Susskind – and in 1984 they released superstring theory. It suggests that matter is made from incredibly small one-dimensional quantum strings 10^-35 m in length that exist in a 10-dimensional environment – six hidden and four visible to us.
These strings have no mass – like light; they spin, vibrate and rotate, yielding different quantum energy states. Their energy states or harmonics correspond to different fundamental particles within the same family. The extra invisible dimensions can be regarded as mathematical artefacts.
David Gross later added 16 extra dimensions to account for bosons – the transmitters of force. A total of 10 dimensions are needed for fermions, and 26 dimensions are needed for bosons in order to be consistent with quantum theory.
Superstring theory (string theory for short) has incorporated supersymmetry in an attempt to unify the four fundamental forces of nature. But physicists are still a long way from being able to say whether string theory is correct.

There's a good capsule history of string theory at superstringtheory.com. That site is maintained (slowly!) by Patricia Schwartz, who was (is?) married to John Schwartz one of the key figures in the development of string physics.
 
thank you for your responses
