Optical Illusion

Optical Illusion 

Optical illusions also know as visual illusions  are tricks of how your brain preseves information  transmitted from your eyes for example creating multiple sets of visual information that other wise put together would not make logical sense.

There are three main forms of optical illusions, 

The First is literal illusions that make images from object that would not normally create these images.

The Second Physiological ones that play on the extent of information taken in by the eyes and brain 

this can be created by different things such as light,motion or color.

The Third is Cognitive Illusions more widely  know as "mind games" playing on sub-conscious
information concluded by small amounts information for example the motion of few circles
back and forth into one postilion if done correctly could look like a figure walking because we would relate the shape and motion to the that of human motion even though  the image is just a handful of circles moving back and forth into one position.

This is a literal illusion as in a actual version of this the three circles spin in different directions and at different speeds creating false movements like the circles inside expanding were as there actually just spinning

This is an example of a "Mind game" similar to the example in the description of
physiological illusions, it simulates human movement

because our brain recognizes the shape and musle movment of a human however the illusion is merely created by a few well caculated circles moving in a repeated pattern.

 

 

 

 

This is an example of psychological illusion when animated the two colored pass threw the vertical black  lines creating the illusion that one Square  is slower than the other however a short interval takes away the black lines to reveal that both squares are traveling in synchronization, the illusion comes from the fact that your brain is trying to proses the information consequently one of the squares appears to be slower or faster than the other.

Studies Of Advertisment and propaganda

many advertisements have both literal meanings as well has hidden messages both of which are created in the advertisement.

This advertisement's literal meaning  is evidential a group of fire men not responding to the obvious emergency situation which they are trained to deal with,
the hidden meaning within this is expected by the advertiser to be figured out by the viewer
as they expect you to conseve the same message but apply it to the situation of there company (the WWF
) sort of asking a moral question like the one displayed here asking if it would be accepted
if fire men just a let a fire burn in front of them following with the statement "you can't afford to be slow in emergency" this statement suggests to the viewer that there situation is an emergency.

 













this is an advertisement for Birm a brand of medicine
the literal meaning of this picture is shown in the glasses invulnerability and the hammer that struck it shattering  creating a role reversal as it would obviously be the other way around in a realistic
situation
However the hidden meaning is linked to the liter one by the phrase "no disease can get to you"
 which suggest to the viewer that thr product will give you the invisibility to diseases just as the
glass to the hammer.

03 The Alphabet 

the first alaphabet was used around 2000BC in ancient egypt during the bronze age it was the representation of the lungage developed by semetic workers around that time, today  most alaphabets have been directly molded from this one for example the greek and phoenician alaphabets.

the proto-canaantine much like it Ancient Egyptian prototype only represents consonants in a system called abjad linknig ever alphabet ever used to phoenician script, the aramatic script adopted as the official script of the persian empire is the bases of all modernised alphabets in asia.

   The Greeks

The Greek alpha adoptied phoenician lettering and became the sole source of all europeian lungages

the greek alphabet is also thought to be the first real modern alphabet as it exchanges cosnotants for vowels.

the literal meaning of this mosaic could be to describe something relating in context to the location it is in ,Greek mosaics were used to tell stories and depict the gods themselfs.

The Romans

several hundred years later the romans adoptied the greek wrighting and lungage and refined and modfied it creating several diffrent styles for diffrent purposes like creating formal and informal types for important and less signifiacant documentations,additionally the roman stonemasons used to hook

the letters to stop there chisels from slipping not only was this effective but also seemed to be aestheticly pleasing.

they also created the "baseline" a tool in typorgaphy were the letters sit on a line which allows it to become perfectly alligened and there fore more more aestheic and easier to depict.

the literall meaning could be the documentation of dates or historical events as it also includes several roman numeirals within the text

Roman chiselings were used for documentations for a variety of purposes.

The romans also largely developed books and creating informal handwrighting styles

these books were known from there Greek name a "Codex"(literally meaning block of wood or book in greek) these codices were a large change from there predesseors which were scrolls , the codex had many advantages over the scroll firstly they could be open flat on any page ,secondly they could be wrote in recto and verso formats and lastely the covers gave trhem versitiality and protection

for these reasons codexs were used from there on all the up threw the middle ages.

This codex is a roman codex it seems to tell a story or could be a historical documentations

as most roman codieses did ,this had been transferd from the earlyer greek codises which achived

a similar culturall use.
