#JustinBieber[超话]#
“’ ”
I saw so many pretty faces before I saw you
Now all I see is you
I’m coming for you
Happy Birthday to Ulove of my life@JustinBieber
30 YEARS! Time goes by so fast.
It’s been amazing to see you become the man you are today
May you always be surrounded by love in the future
When I first met you, you were still the little boy sitting on the stairs playing guitar.
I didn't expect that I had spent half of your life with you in the blink of an eye.
Your voice has accompanied me like an angel for countless days and nights.
I’m so honored to be your belieber
As long as you love me
I’ll be your platinum
I’ll be your sliver
I’ll be your gold✨

印第安人传说中关于#彩虹乌鸦#的故事有两个关键点，（1）乌鸦是无私的，（2）乌鸦是彩色的。
第一点，乌鸦的确存在一定程度的利他主义，会给那些没找到吃的的同类分享食物，而且无私的乌鸦比自私的乌鸦更有可能得到有吸引力的配偶。乌鸦也被认为是鸟类王国中最聪明和最健谈的动物，以前有科学家做实验，带着面具捕捉某只乌鸦一段时间后把乌鸦放了，然后很快附近所有社区的乌鸦都通过聊天知道了带着面具那个人是大坏蛋。
第二点，鸟类的虹彩颜色通常是由羽毛中的分层纳米结构引起的，这些结构的间隔可以最强烈地反射特定波长的光。乌鸦羽毛的紫色和蓝色是离轴反射，许多鸦科动物在紫外线下具有高度反射性，展现出虹彩的颜色。但我们可怜的人类看不到鸟儿真正的颜色，在鸟儿眼里，鸦科动物在紫外线下可能会呈明亮的彩虹颜色。
既然人类只能看到黑色的乌鸦，那彩虹乌鸦的故事是怎么出现的呢？一种猜测是来自四色视觉的人。众所周知人类中有一部分女性拥有四色视觉，她们多出一种视锥细胞。因为女性有两条X染色体，她们可能携带两个不同版本关于视锥细胞的基因，每个版本都编码一个对光谱中略有不同部分敏感的视锥细胞（而男性携带这种基因变异时会导致色盲）。
所以需要测试一下四色视觉的人眼中的乌鸦是什么样子，就可以知道彩虹乌鸦的故事是不是来自很久以前某个印第安女性的四色视者。
