路的盡頭是什麼?太陽。許多城鎮的道路都是東西走向,每年有兩天,太陽會從中間升起和落下。在世界上的某些地方,今天(在其他地方則是明天)就是這樣的一天:春分。 這不僅是黑夜("aequus"-"nox")和白天時間相等的一天,也是太陽準確地從東方升起並從正西方落下的一天。這裡展示的是加拿大艾伯塔省一條風景如畫的鄉村公路,這條公路大致呈東西走向。這張圖片拍攝於 2021 年的九月分,但每年的幾何形狀都是一樣的。 在許多文化中,三月分被認為是一個季節的第一天,通常是地球北半球的春天和南半球的秋天。您最喜歡的街道是東西走向的嗎?今晚,在日落時分,您只需匆匆一瞥,便可知曉。
原文:What's that at the end of the road? The Sun. Many towns have roads that run east-west, and on two days each year, the Sun rises and sets right down the middle. Today, in some parts of the world (tomorrow in others), is one of those days: an equinox. Not only is this a day of equal night ("aequus"-"nox") and day time, but also a day when the sun rises precisely to the east and sets due west. Displayed here is a picturesque rural road in Alberta, Canada that runs approximately east-west. The featured image was taken during the September Equinox of 2021, but the geometry remains the same every year. In many cultures, this March equinox is taken to be the first day of a season, typically spring in Earth's northern hemisphere, and autumn in the south. Does your favorite street run east-west? Tonight, at sunset, you can find out with a quick glance.
