Optical Illusions


Illusions of the senses tell us the truth about perception
-Teuber,1960
Illusions are fascinating to most people. Some of the illusions have been known since antiquity. The scientific study of illusions dates back to the beginning of the nineteenth century when scientists got interested in perception. Since then there has been enduring interest, and illusions have been used as tools in the study of perception. An important strategy in finding out how perception operates is to observe situations in which mis-perceptions occur. By carefully altering the stimuli and testing the changes in visual perception psychologists tried to gain insight into the principles of perception.

An optical illusion(also called a visual illusion) is characterized by visually perceived images that are deceptive or misleading.Most effects have their basis in the visual pathway, not in the optics of the eye.There are so many websites dedicated to optical illusions.Some pictures are here for reference and for detailed description you can check out the links given at the bottom of this post.

2. Jesus OR Jesus with followers
Anamorphism
An Anamorphoscope, a conical or cylindrical mirror is placed on the drawing or a painting to transform a flat distorted image into a three dimensional picture that can be viewed from many angles. The deformed image is painted on a plane surface surrounding the mirror. By looking uniquely into the mirror, the image appears undeformed. Anamorphoscopes were invented in China and brought to Italy in the 16th century, about the time Renaissance artists like Leonardo da Vinci were mastering 3D and discovering slant anamorphosis.Recently I have seen the movie ANAMORPH which inspired me to get a look at this field.Some anamorphisms...












Ambigram
An Ambigram is a sentance or a single word that is written in such way, that it becomes readable even if you rotate it. John Langdon is a father of ambigrams.He did work for The Da Vinci Code movie, and to my knowledge, he was an inspiration to Dan Brown for his main character called Robert Langdon. John's ambigrams apeared not only in the movie, but also in original David Brown's books: "Angels & Demons" and "The DaVinci Code".Check out these cool ambigrams..

Google Facts

The name Google is a spelling error. The founders of the site, Larry page and Sergey Brin , thought they were going for Googol .. Googol is the mathematical term for 1 followed by 100 zeros. Initially, Larry and Sergey Brin called their search engine BackRub , named for its analysis of the of the web's "back links." The reason the google page is so bare is because t he founder didn't know HTML and just wanted a quick interface. The company's first office was in a garage , in Menlo Park, California .

Digg Source Code has a "Secret Message"

Recently I came to know about this, the homepage of Digg contains a "Secret Message" . This secret message is in the source code of the Home Page of the website in the form of a comment at the very bottom .After analyzing the code it seems that some physics-lover has worked on the code of the website.The message is ::: This line is a comment and thus not visible on the website but can easily be seen in the source code of the homepage.These are not just random numbers but are a result of very smart physics work done at the Digg labs. What is the significance of these numbers ? Take a guess (Hint :: Relate these numbers to physics)... OK,here is the answer..... 2.01355321270u :: This is the atomic mass of the hydrogen isotope known as D euterium. 137.03599911 :: This is a complicated one and really a geek in physics can figure this out.This is I nverse of the Sommerfield fine-structure constant. 6.6742x10-11m3kg-1s-2 ::The last two numbers are the same.This one is v...
