On early US patriotism to choose quark color charge labels

According to the best source, "red, white, and blue" were proposed in honour of France, not the United States. As discussed in the answer to "Quantum chromodynamics - an origin of the ...

Historically how it was discovered that we need fields to describe matter?

The Wikipedia coverage of the history is pretty spot on, and there is hardly a point in exactly dating the incremental formal developments of the second quantization picture of Dirac, Jordan, Wigner, ...

On the naming of quantum chromodynamics

The use of color to refer to the "color charge" characteristic of QCD is present in Gell-Mann, Fritzsch and Bardeen's original work from 1972. This terminology was apparently due to Gell-Mann: "...

Does anyone know the physics student who passed a quantum mechanics oral exam without taking quantum mechanics?

H.E. Stanley's 2002 interview has Harvard, taking quantum field theory ahead of quantum mechanics, Schwinger and a tough lecturer (Coleman), Wendell Furry, the electromagnetism course, and an exam. ...

The origin of Renormalization Group

I think the quote (a reference would be good) is more about the OPE than the RG although they are very closely related and must have germinated in Wilson's mind concurrently. About Wilson's priority ...

How has the modelling of classical electrodynamics changed since Maxwell?

We will take the cutoff to be 1873, the publication date of the first edition of Maxwell's treatise. I'm not an expert in electrodynamics by any stretch, but here are some of the things that come to ...

Origin of the term "field" (in "vector field")

From Mathword "Earliest Known Uses of Some of the Words of Mathematics" VECTOR FIELD is found in 1905 in “The Present Problems of Geometry” by Dr. Edward Kasner in Congress of Arts and ...

Original derivation of the Dyson equation

It is equation (63) in his epochal second paper, Dyson, F J (1949). "The S matrix in quantum electrodynamics", Phys Rev 75 (11), 1736. He refers to his first one, but the systematics in ...

How did Schrödinger do quantum mechanics with wave functions?

I don't think Heisenberg and Schrödinger calculated probabilities at the beginning, as the role of probabilities in quantum mechanics was not known then. Schrödinger initially interpreted the squared ...

Were Feynman diagrams motivated by the cosmological constant problem?

The first Feynman diagram in print appeared in Fig 1 , p 772 of "Space-Time Approach to Quantum Electrodynamics", R P Feynman, Phys Rev 76 (1949) 769 – 789, published 15 September 1949, not ...

What is the history of $T\neq 0$ quantum field theory?

An important early work is L. Dolan and R. Jackiw, Phys. Rev. D 9, 3320 (1974), which unfortunately is behind a paywall. In their introduction they refer to earlier work by Kirzhnits and Linde, Phys. ...

Looking for the source of a quote in QFT history

@Oбжорoв answered this in the PSE: a source is Robert J. Sciamanda, Am. J. Phys. 81, 645 (2013); doi: 10.1119/1.4812316, By extending some of Hobson’s ideas, I arrive at the conclusion that in ...

Historically how it was discovered that we need fields to describe matter?

The development of concept of "Field' to describe the events happening around us in connection with various interactions which operated at "action at a distance' has very early beginning. ...

History of the fock space based quantization of fields

It's a long story, and students are constantly confused about the point even today. The basic appreciation that a quantized field is an infinite collection of quantum oscillators suitably organized is ...
