Discussion Overview

The discussion revolves around differing interpretations of the sun's position and apparent size at different times of the day, as illustrated by a story involving two children. Participants explore the implications of perception, atmospheric effects, and the nature of the sun's appearance in the sky.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant recounts a story where one child argues that the sun appears larger when it is closer to the ground in the morning, while another claims it should appear larger at noon due to proximity to the heat source.
  • Another participant suggests that both children are incorrect, proposing that the sun's appearance near the horizon is influenced by atmospheric refraction and optical illusions, which distort its shape and size.
  • This participant also mentions a psychological aspect, comparing the perception of distance to rungs on a ladder, suggesting that our brains misinterpret the sun's position.
  • A later post references an external source as a "correct answer," but does not clarify the content or reasoning behind it.

Areas of Agreement / Disagreement

Participants do not reach a consensus; there are multiple competing views regarding the children's arguments and the nature of the sun's appearance.

Contextual Notes

Participants express differing interpretations of visual perception and atmospheric effects, but do not resolve the underlying assumptions about the children's claims or the nature of the sun's appearance.

Recently, I have read a old book with an article about two kids arguing the problem of Sun.

One day, Confucius heard two kids arguing on the road.
One said "in the morning, the sun rises, it is closer to the ground and look as big as a roof of the carriage. In the afternoon , the sun is far from the ground and look like a dish. It is because an object at faraway place look smaller than the close."
Another said " It should be reversed. In the morning, it is cooler ,but at noon, we seem to be living in the hot water. Since we are nearing a heat source, we feel hotter."

Actually, who is right and why?

I think both are wrong...
 
The image of the sun near the horizon is part illusion and part due to atmospheric refraction. While the image is not really larger, it is distorted making the sun appear to be an oblate spheroid [oval] at the horizon. The illusory part can be blamed on the brain, which fools itself into believing the sun is closer when near the ground. I believe this is at least partly related to our instinctive fear of heights. Which appears more distant, the tenth rung of a ladder as it leans against your house, or the tenth rung of the same ladder lying flat on the ground? The other boy is also wrong for more obvious reasons [the sun has already been shining for half the day].
 
Confusious say " Man who sees sunrise, will live his life, and see sunset."
 
thx a lot
