“立扫把挑战”,你试了吗?

导读

 

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。”

 

A viral tweet suggests that NASA said Monday was the only day the standing broom trick would work, because of the earths 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(210日)扫把才能立起来。

 

 

 

We couldnt 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 earths 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)。

 

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。

 

除了科学之外,周一的#立扫把挑战#确实产生了一些让人印象深刻的视频和照片。一个Twitter用户成功地一次立起了三个扫把,一把刀和一根拐杖。

 

 

 

 

网友评论:

 

 

A brooms center of gravity is low and rests directly over its bristles, CNN explains. This means, if you can get the bristles positioned like a tripod to support the broom handle, your broom will stand upright, no matter what day it is.

美国有线电视新闻网解释说,扫帚的重心很低,直接停在它的鬃毛上。这意味着,如果你能把扫帚的鬃毛像三脚架一样固定在扫帚柄上,那么不管什么日子,你的扫帚都会直立起来。

 

The standing broom is not new to 2020, either. The trick, which dates back to the 90s, went viral most recently in 2012. Back then, the viral explanation was not gravitational pull, but that the planets are aligned, Wired reported at the time.

“站着的扫帚”在2020年也不是什么新鲜事。这个可以追溯到上世纪90年代在2012年风靡一时的魔术。当时,《连线》杂志报道,那时有点荒谬的解释不是“引力”,而是“行星是对齐的”。

 

Similar hoaxes periodically circulate the web, such as the Earths equinoxes affecting an eggs ability to balance and the Coriolis effect determining which direction water spirals down drains and toilets in different hemispheres.

类似的恶作剧周期性地在网络中传播,例如地球的春分点影响鸡蛋的平衡能力,而科里奥利效应则决定了水在不同半球的排水方向和抽水马桶的旋转方向。

 

Although they are entertaining and, for the most part, harmless, all the aforementioned theories have been proven unequivocally false.

尽管这些理论很有趣,而且在很大程度上是无害的,但上述所有理论已被明确证明是错误的。

 

你是不是也在家“立扫把”了?
