quora网友:这里有个诀窍:当屏幕想要瞒过你的眼睛骗你说屏幕的颜色是白色时,屏幕会亮起这三种颜色。这会刺激你眼睛中的三个RGB传感器,就好比这三个传感器是被真白光刺激到的一样。这就是你大脑所知道的一切——因为三个颜色传感器都检测感应到了光线——传译给你大脑的信息是这道光是白光。你的大脑被愚弄了......

Your color TV uses one of the greatest optical illusions of all. It makes red green and blue dots appear to be white.
你的彩色电视机采用了最伟大的光学错觉原理之一。它可以让红、绿、蓝三种颜色的点变成白色的。
Look up really close at TV or computer screen that is displaying the color white and all you’ll see are red green and blue dots no white ones. (You may need a magnifying glass to see the tiny individual dots.) But if you sit back they blur together and make white.
凑非常近去看明明显示白色的电视或电脑屏幕时,你看到的却全是红、绿和蓝点,完全没有白点。(你可能需要放大镜才能看到这些微小的单个点。)但是如果你坐在后面看时,那些点就会模糊成一片然后变成白色。
[In a comment Tim Volkov made an excellent suggestion: No magnifying glass needed - just a drop of water on the screen! That acts an an excellent high power magnifying glass.]
在一个评论回复中,蒂姆·沃尔科夫(Tim Volkov)提了一个很好的建议:不需要用到放大镜——只需要在屏幕上滴一滴水。其使用效果跟用高倍放大镜一样。
Your eye has three color sensors: one each for red green and blue (RGB). True white light from the sun contains all the colors of the rainbow not just RGB. True white makes all three RGB sensors respond.
你的眼睛有三个颜色传感器:每一个各能看到红绿蓝三种颜色(RGB)。来自太阳的真白光包含了彩虹的所有颜色,不仅仅是红绿蓝三色。这三种红绿蓝颜色传感器都能感应到真正的白色。
Here’s the trick: when the screen wants to deceive your eye into thinking the color is white it lights up all three colors. That excites all three RGB sensors in your eye in exactly the same way they would be excited by true white sunlight. Since that is all your brain knows – that all three have detected light – it interprets it as white light. Your brain is fooled.
这里有个诀窍:当屏幕想要瞒过你的眼睛骗你说屏幕的颜色是白色时,屏幕会亮起这三种颜色。这会刺激你眼睛中的三个RGB传感器,就好比这三个传感器是被真白光刺激到的一样。这就是你大脑所知道的一切——因为三个颜色传感器都检测感应到了光线——传译给你大脑的信息是这道光是白光。你的大脑被愚弄了。
Some people are reputed to have four sensors not three so they would not be fooled by false TV white. What would it look like to them? We don’t have the words to describe the colors they see because so few of us have that ability. They probably would call us “colorblind” for getting TV White confused with True White.
有些人被认为有四个传感器,而不是三个,所以他们不会被虚假的电视白光所愚弄。那么他们看到的会是什么样子的呢?我们无法描述他们所看到的颜色是什么,因为只有极少数人有这种能力。他们或许会叫我们“色盲”,因为我们无法辨别电视白光和真正的白光。

Bill Hewlett and Dave Packard tossed a coin yes they had to toss a coin to decide the name of the company. Both the founders were dubious about the name for the company. Packard-Hewlett or Hewlett-Packard. Packard won the toss but instead they named it as Hewlett-Packard.
比尔·休利特和戴夫·佩克德抛硬币,没错,他们通过抛硬币来决定公司的名称。两位创始人都对公司的名称争执不下,到底是叫佩克德-休利特还是休利特-佩克德。佩克德猜对了硬币正反面,但他们二人最终却将公司命名为休利特-佩克德。
PH would be so weird.
如果惠普公司是叫HP的话那实在是太怪了。
Initially Skype was named as Sky-Peer-to-Peer. Then it was minimized and named as Skyper. Again they skipped the alphabet ‘r’ and changed it to Skype when they realized that ‘skyper.com’ domain was already taken!
Skype软件起初是叫“Sky-peer-to-peer”。之后,被缩减成了“Skyper”。后来,当他们了解到“Skyper.com”的域名已经被人注册之后,再一次进行缩减,舍弃了字母“r”,变成“Skype”。
Thank you for reading
