The sun's energy can be used to pump water for irrigation, etc. But it is important not to lower the natural water table which could result in more drought. India, 2007  |

Confucius and the Sun#65281; Can you answer this question with which even the great saint Confucius was confused?   Quote:
A well known story "Two Children arguing about the sun" (From Lie Zi, ca. 500BC):
-------------------------
On the way traveling to the east, Confucius saw two children were arguing. One child thought that the sun is nearer to us at daybreak and far away from us at noon, because in the morning it is as big as the canopy of a carriage, but at noon only the size of a plate or a bowl. The other contended that the sun was far away at dawn and nearby at midday, because when the sun comes out, it is very cool, but at midday it is as hot as putting your hand in boiling water. Confucius was unable to settle the matter for them. The children laughed at him, saying, "Who decided that you were a wise man?"
-------------------------
I think the second kid should be correct. the question is: what is wrong with the first kid's argument or why the Sun in the morning looks bigger? https://physics.stackexchange.com/q...ed-confucius |

In the early days of the country, the flag of Peru used to carry a smiling sun. It was also on the early stamps of the country, 1870s.  (Idebee, The sun appears larger or smaller because of atmospheric conditions, right? K.) |

Hi, Kris, I think it's called optical illusion in English.  This is not a stamp, but I really like it, anyway! |

Looks like this is a popular design? Perhaps from Inca cilvilization?  |
