假期到了,当你兴致勃勃的坐在电视机前舔屏时,背后突然传来一声老妈的怒吼:“离电视那么近,眼睛还有要不要啦!”那么,坐得离电视太近真的更伤眼睛吗??事实上,对于如今的电视机来说,这并没有什么用。
下面给大家科普几个颠覆常识的“冷姿势”,拿好小本本,知识点来啦!
Sitting too close to the TV won't harm your eyes more
坐得离电视太近更伤眼睛?多虑啦!
While watching a lot of TV can cause eye fatigue and potentially harm your vision, sitting too close doesn't make much of a difference, if any. However, this myth was true back before the 1950s, when companies made televisions that emitted dangerous levels of radiation...up to 100,000 times more than what federal officials deemed safe.
虽然整天沉迷电视确实会导致眼疲劳并且可能损伤你的视力,但坐得离电视近一点并不会对眼睛危害更大。但是,这个在江湖上的传说在20世纪50年代之前的确是真的,因为当时生产的电视机会放射出大量危险级别的辐射——远比美国联邦官员们所声称的安全放射量高出10万倍。
There's no such thing as an alpha wolf
头狼??不存在的~
A wildlife biologist by the name of L. David Mech published a book based on his observations of wolves in the wild. In it, he mentioned that he noticed "alpha wolves" leading small packs, and the popularity of the book made that term a common one. However, what Mech observed was actually just wolf parents and their grown cubs, so the concept of an "alpha wolf" as we know it is almost entirely wrong. Mech has tried to take his book out of print, and even wrote a paper correcting it.
