Don't trust what you see :)

We always trust what we see from our own eyes, but after looking at some pictures below, i can make sure u won't trust your eyes again.

  • Illusions

Delightful illusions

Distortion illusions

The famous Cafe Wall Illusion was discovered by Richard Gregory, on a cafe wall in Bristol, England. It develops when a staggered arrangement of light and dark bricks are separated by thin lines of 'mortar' whose brightness is intermediate between the brightness of the light and dark bricks. This creates a powerful impression of criss-crossing 'slant' in the perfectly horizontal 'mortar' lines.

This is a perfectly round circle, but the slanting lines appear to distort it.
Distorted Circle
The vertical lines are straight and parallel, but they look as if they are bowed outwards. The slanting lines simulate perspective and create a false impression of depth. Discovered by the physiologist Ewald Hering (1861).
Hering's Illusion
Probably the most famous and most studied illusion was created by German psychiatrist Franz M�ller-Lyer in 1889. Which of the two vertical line segments is longer? Although your visual system tells you that the right one is longer, a ruler would confirm that they are equal in length.
Mueller-Lyer
The horizontal lines are parallel, but the slanting lines makes them appear to diverge. Discovered in 1860 by F. Z�llner. He described it in a letter to physicist and scholar J. C. Poggendorff, editor of Annalen der Physik und Chemie, who subsequently discovered the related Poggendorff illusion.

Ambiguous illusions
The white triangle looks very real, although there's no triangle per se.

Motion Illutions

Ouchi 
Akiyoshi Kitaoka "Rotating Snakes" illusion presents an example of radial drift illusion caused by line ambiguity in peripheral visual field. Even though this image has been downsized and reproduced in black and white, if you stare at the center of this image the illusion of rotational drift in the periphery is obvious. This illusion is most likely due to a bug in the cortical lateral line-resolution process which causes ambiguous data in the visual periphery to remain unresolved, thus lines cannot hold and instead creep and drift, creating the illusion of gradual radial movement. This creeping of line and shade in the periphery is similar to animated hallucinations seen on a light psychedelic trip.[
Rotating Snakes

Stare at the center and move your head forwards and backwards.

Unstable Illusions

Some two-dimensional figures can be interpreted as solid objects in more than one way. A well-known example of this is the flat representation of a wire-frame cube, which can be seen as if from above, or below.

墨二分钟7.4强震　1600幢房屋倒塌5伤

墨二分钟7.4强震　1600幢房屋倒塌5伤
嘿，又是天灾的发生，这个地球真的病了。世界末日会到来吗？如果会，那会是几时呢？这两个问题都没有实际的答案，就连下一秒钟会发生什么事情我们都无法预知。既然不能预先知道，我们就不必去烦恼，我们需要做的事是用一辈子的时间来完成我们想要完成和必须要完成的事情，那就足够了。

很多时候天灾发生都是因为人类的所作所为而发生的。人类是最聪明的动物，就因为聪明，所以我们无时无刻都在破坏周围的环境，造成灾难的发生。现在是时候我们该做些保护地球的活动，来展延和预防末日的到来。

SPM result released

Today is the date of SPM result released, this date will influence all SPM candidates who was taking SPM at the past year to become so nervous at the day before today and the day before tomorrow (means yesterday and today).

This date make me recall back last time when i was finished studied at secondary school and waiting for the SPM result, i am also very nervous to know hows my SPM result, is't flying color or getting grade around "elephant" although i already know my degree of standard.

My SPM result showed that i had no paying effort on study during secondary school. Now i am study at university and i feel regret why i am not work hard when i was in secondary school. I regret because i have no good knowledge base especially my English grammar. Now studying at MMU and i try to improve my English but it was so hard for me to achieve this target. I never get an A in the grade of English exam paper in MMU and even the MUET test, i had used twice time to only get a band 3.

In MMU, i was choose to studied mechanical engineering for my degree but i was fail this mission, haiz, this mission fail make my parents disappointed again. Now i transfer my course to marketing management and i hope i can pay full of my hard work on it to achieved the best result, i don't want to disappointed my parents and myself again.

Smartphone

智能手机（smartphone) 对现代的人类已成为了必需品，身边的朋友也一个个将基本手机升级至 智能手机 。朋友们也呼吁我把手机换了，因为他有多功能，还备有免费通话和简讯。 其实我也很想拥有它，但我还是做了决定，不换了。

为何我会选择这个决定，因为手机对我在中学时期留下了阴影。当时我犯下了一个很大的错，一个不能原谅的错，现在那个情景在我脑海里还是留下了深刻的印象，父母亲对我极大的绝望和失望。现在我不想再重复犯下了类似的错误，所以我决定不换电话了，等到哪天电话坏了才打算吧。

人缘

夜深人静的夜里，我独自一个人坐在电脑前，脑袋里出现了疑问，不懂大家有过相同的问题吗，也许问题很无聊，但我想了在想，也得不到真确的答案.

一些人，我们轻易地沟通就能成为好朋友，
一些人，长久的沟通才成为好朋友，
一些人，却只能够当普通朋友，即使在一起久了，
一些人，则不懂算不算朋友，碰面时就只是一个微笑，或者是挥一挥手，而可能不曾说过话，
还有一些人，就只是短暂的朋友，早前是朋友，之后则变成了陌生人。

这一切，可能是老天的安排，每个人与人之间都有不同阶层的缘分。
