Discussion Overview

The discussion revolves around the etymology of the term "Red Sea" and includes a tangential exploration of color perception, particularly regarding the sky. Participants engage in a light-hearted exchange about the meanings and implications of color names.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant questions why the Red Sea is called the Red Sea, seeking clarification.
  • Another participant provides a link to a search engine as a response, suggesting that the answer can be found online.
  • A separate thread of conversation emerges regarding the color of the sky, with one participant questioning the meaning of "real" in this context.
  • Another participant explains the phenomenon of Rayleigh scattering as a reason for the blue appearance of the sky, detailing how light interacts with atmospheric particles.
  • A humorous exchange occurs involving the term "red herring," illustrating the playful nature of the discussion.

Areas of Agreement / Disagreement

The discussion does not reach a consensus on the original question about the Red Sea's name, and multiple viewpoints regarding color perception are presented without resolution.

Contextual Notes

Participants express differing interpretations of color and its meanings, but no definitive conclusions are drawn regarding the etymology of the Red Sea or the nature of color perception.

I guess it depends on what you consider "sky". It might be more informative to learn why you see blue in the sky:

A portion of the light coming from the sun scatters off molecules and other small particles in the atmosphere. It is this scattered light that gives the sky its brightness and its color. As previously explained, Rayleigh scattering is inversely proportional to the fourth power of wavelength, so that shorter wavelength violet and blue light will scatter more than the longer wavelengths (yellow and especially red light). The resulting color, which appears like a pale blue, actually is a "weighted average" of all the scattered colors, mainly blue and green (violet, though strongly scattered, is a minor component of the solar spectrum and is less efficiently detected by the human eye); its hue is intermediate between blue and green.[3] Conversely, glancing toward the sun, the colors that were not scattered away—the longer wavelengths such as red and yellow light—are visible, giving the sun itself a slightly yellowish hue. Viewed from outer space, instead, the sky is black and the sun is white.

Why is a red herring called a red herring? It is neither red, nor a herring.

A: What's green and is nailed to the wall?
B: I don't know.
A: A red herring.
B: But a red herring isn't green.
A: So paint it green.
B: But a red herring isn't nailed to the wall.
A: So nail it to the wall.
