鬼打墙

求助编辑百科名片

所谓鬼打墙，就是在夜晚或郊外，会在一个圈子里 走不出去。这种现象首先是真实存在的。有很多人经历过。

试验

　　那么 这种现象是怎么造成的呢，其实生物学已经有了明确的答案。
　　首先做一个实验。把一只野鸭的 眼睛蒙上，再把它扔向天空，它就开始飞
  
鬼打墙
　　，但如果是开阔的天空，你会发现，它肯定是飞出的一个圆圈。
　　你不信，可以自己再试一下，把自己的眼睛蒙住，在学校的操场上，凭自己的感觉走直线，最后你发现 你走的也是一个大大的圆圈。
　　一言概括，生物运动的本质是圆周运动。如果没有目标，任何生物的本能运动都是圆周。
　　为什么呢？ 因为生物的身体结构有细微的差别，比如鸟的翅膀，两个翅膀的力量和肌肉发达程度有细微的差别。人的两条腿的长短和力量也有差别，这样迈出的步的距离会有差别，比如左腿迈的步子距离长 ，右腿迈的距离短，积累走下来，肯定是一个大大的圆圈，其他生物也是这个道理。
　　但是为什么生物能保持直线运动呢，比如人 为什么走出的是直线呢。因为我们用眼睛在不断的修正方向，也就是我们大脑在做定位和修正。不断的修正我们的差距，所以就走成了直线。

解决方法

　　1.如遇到鬼打墙的事件，不要慌张，集中一切注意力，睁开眼睛。
　　2.夜间行路带把手电筒就行了。
　　3.迷了路要问人。
　　4.根据北极星的位置来辨别方向。

Recluse

Once every so often, I like to withdraw into myself and shut out the world- whimsically. Just stop talking. No real reasons. Not really the first time. Perhaps, perhaps, perhaps, this is a part of me that needs some getting used to. Perhaps, the people who knows me, knows this happens. Perhaps, the people who do, doesnt exist. Perhaps i'm wrong- Perhaps this is selfish. But once, just once, every so often- i'd like to claim my leave from social behaviors. Just once every so often, i'd like to disappear. Take the phone off the hook- for ages. -I'm sorry though, if my habits hurt. And i do so appreciate the concern too. But, like my daddy says: ourself knows best. sk

this is really bad.

I have officially lost interest in sleep. (Or work, for that matter.) Came across an old blog post where i did this huge list of personality tests and decided to do sth immensely useless: hahha THEN & NOWW! XD so here we go, really quick! 1) THEN: Your Brain is 47% Female, 53% Male Your brain is a healthy mix of male and female You are both sensitive and savvy Rational and reasonable, you tend to keep level headed But you also tend to wear your heart on your sleeve What Gender Is Your Brain? NOW:  Your Brain is 67% Female, 33% Male Your brain leans female You think with your heart, not your head Sweet and considerate, you are a giver But you're tough enough not to let anyone take advantage of you! 2) THEN:   You Are Pretty Logical You're a bit of a wizard when it comes to logic While you don't have perfect l...

End of exams.

i don't feel much about the end of exams actually- i guess that is a signal that perhaps i didn't work hard enough and build up the hunger for relaxation while mugging, hence i don't feel the surge of relief. Ah- i miss that feeling much actually. next sem will be a better sem. YES IT WILL BE. -------------------------- Preceptorship will commence on the coming Monday. I am rather excited about it, and I look forward to a time of learning and actually applying the knowledge that i have learnt in school. I believe if you ever meet a pharmer undergrad, you will hear the same unanimous complain about how there doesn't seem to be a meaning in doing what we are doing. How it feels like we are simply dead memorising the cold, hard, facts. How we all disagree with the system and feel that university education should be about thinking- and how it's been a long time since we last did more of that. For me, the curriculum has honestly entrenched certain doubts in this career p...
