Discussion Overview

The discussion revolves around the various associations and definitions of the term "light," encompassing both scientific and non-scientific perspectives. Participants are encouraged to contribute a wide range of thoughts related to light, including its properties, cultural references, and scientific implications.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants provide non-scientific definitions of light, associating it with concepts like weightlessness, superficiality, and cultural references.
  • Others propose scientific definitions, discussing light as electromagnetic radiation and its dual nature as both a wave and a particle.
  • One participant mentions the relationship between light and the electromagnetic spectrum, noting that visible light is a small part of it.
  • There are references to various phenomena associated with light, such as diffraction, interference, and reflection.
  • Some participants express curiosity about the philosophical implications of light, including its connection to time and perception.
  • Humorous and light-hearted contributions include cultural references and personal anecdotes related to light.

Areas of Agreement / Disagreement

Participants express a mix of non-scientific and scientific views on the concept of light, with no clear consensus on a singular definition or understanding. The discussion includes both serious scientific inquiry and playful interpretations, indicating a range of perspectives.

Contextual Notes

Some definitions and associations presented are subjective and may depend on personal experiences or cultural contexts. The scientific definitions vary in detail and complexity, reflecting different levels of understanding among participants.

Who May Find This Useful

This discussion may be of interest to individuals exploring the concept of light from both scientific and cultural perspectives, as well as those looking for a diverse range of associations related to the term.

When the word "light" is mentioned what comes into your mind?

When the word "light" is mentioned what comes into your mind? Not only the basic definition, list everything you can think of. No need to explain.

The purpose behind this is I'm creating a massive mind map and want to make sure I get everything included.

Let's try and keep this post as an excellent reference for people wanting to know what light is and what's associated with light :)

Good luck

What light is:

not heavy
type of beer or soft drink
kind of food that doesn't make one fat
what to do to your barbeque when it's time to cook (ignite)
frail
fickle
comic
superficial
trivial
easy
kind of person who thinks in shallow ideas (light-weight thinker)
 
^ I guess the above is enough for non-science definitions.

Can we get some real science definitions going? :D

A massive mind map of something that is massless? :confused:

(Cue one of our ever-popular debates about "rest mass / invariant mass" versus "relativistic mass." :rolleyes:)
 
Gentlemen prefer blondes because where there's light there's heat.
 
Light has dual nature, diffraction and interference, i.e. which is wave and particle nature.

Its a electromagnetic wave by Bohr.

PM for more help
 
light is something which gives us the sense of sight, having dual nature, a kind of radiation, a energy, which shows many phenomenas like differaction, interference, reflaction, scattering etc etc

Photons, aka electromagnetic radiation.
 
If you want a scientific definition, "light" is radiation and is just that part of the electromagnetic (EM) radiation spectrum which is naturally visible to humans. The term also may include the lower infrared frequencies and the higher ultraviolet frequencies that are not visible. The only difference between low frequency waves like radio waves, visible light and high frequency waves such as gamma radiation is the inversely related frequency/wave length. Long waves mean low frequency, short waves mean high frequency. All EM radiation travels at the "speed of light" in a vacuum. The energy of any EM radiation is a direct function of its frequency.

Dark because "all experiments on light must be done in the dark". Was it Goethe who said something like that?

Is that the same guy from "pride Goethe before a fall", or someone else?

Doesn't sound like it. So you may as well lighten up and have a lite beer.

Hence the name. A larger slice would be heavy.

I think of coca-cola light (but in my brain it's "coca light"), also known as Diet Coke in the USA.

The first thing that comes to mind is photons and then time. I am always impressed that when we look at stars we see light that came from the past in the present. This then leads me to think about worldlines and light cones.

This is really cute :biggrin: lol

I was taught that the speed of dark is actually faster than the speed of light because dark needs to get out of the way.
