相信很多人的朋友圈,这两天都被这样一条消息刷屏了:
“NASA(美国国家航空航天局)说因为今天地球完美的重力角度,是唯一一个可以让扫把独自站立的日子。”
于是,很多人的微博和朋友圈的画风就变成了这样↓↓↓
一时间,全球网友都加入了这场#立扫把挑战“。
A viral tweet suggests that NASA said Monday was the only day the "standing broom" trick would work, because of the earth's gravitational pull.
一条广为流传的推文称,美国国家航空航天局表示,由于地球的引力,只有在本周一(2月10日)扫把才能立起来。
We couldn't find anything from NASA to support the tweet. But as with many things on the internet, people ran with it.
我们找不到任何来自美国国家航空航天局的消息来支持这条推文。但就像互联网上的许多东西一样,人们都在跟风。
Fun, right? Right.
很有趣,对吧?是的。
But the truth is, you can make a broom stand upright today... and tomorrow and the day after... and the day after that.
但事实是,今天,明天和后天,以及之后的每一天,你都可以让扫把立起来。
It has nothing to do with the earth's gravitational pull on a certain day. It also has nothing to do with the vernal equinox (another day of the year when this "magic" supposedly happens).
这与某一天的地球引力无关,也与春分无关(春分是传说中另一个扫帚站立这种“魔法”会发生的日子)。
vernal equinox:春分
Instead, it has everything to do with balance.
相反,这事儿与平衡有关。
The center of gravity is low on a broom, and rests directly over the bristles. Which means, if you can get the bristles positioned like a tripod, your broom will stand upright any day of the year.
扫把的重心很低,位于下方的扫把毛上。也就是说,如果你能把扫把毛像三脚架一样立好,你的扫把在一年中的任何一天都能立起来。
当地时间11日,NASA宇航员阿尔文·德鲁(Alvin Drew)和科学家莎拉·诺布尔(Sarah Noble)对#NASA立扫把挑战#做出了回应,表明让扫把立起来的基本物理学在每一天都有效。
人民日报微博也发文表示,“扫帚能立起来与今天的引力无关,每天都可以立,只要你找到平衡!你家的扫帚立起来了吗?”
还有人发现,岂止扫把能立住,简直万物皆可立,果然高手在民间啊!
