Optical Illusions

                                                     The Things that “Blow” Your Mind

     Did you know that everything we see is an illusion? EVERYTHING tricks our brain any way it can. You will never know, anytime in your life, what is coming next. An illusion could be found in nature, military, and even in people! There is also more than five different types of illusions, such as cognitive illusions, distorting illusions, ambiguous illusions, or paradox illusions (those are my favorite.) After that their is what is going on in the brain when we see illusions.

                                                                         In Nature

     Have you ever wandered into a creek, woods, or forest and then see something then all of a sudden it’s gone? Well, if you think that something is wrong with you, then you are wrong because that’s normal. Nature is filled with optical illusions. Plus, maybe you will see a random ball floating, but you are actually are just seeing tree branches making out objects. Also, hidden pictures in objects test your attention to detail and your object-recognition abilities.

                                                                  Creepy Crawlies

     When you go into the woods do you see weird things? Well if you do then you are normal because actually, if you didn’t see weird things like that then you wouldn’t be human. Maybe you’ll see a moving piece of dung. Maybe you’ll even see a leaf with gooey stuff all over it. Well those are just little creepy crawly bugs. The moving piece of dung is probably just a caterpillar and the “dead” leaf is probably a dead leaf bug (they look like leaves.)

     When you are in a forest, woods, or a creek and you are collecting sticks and then you pick up one and it has a bunch of little twigs attached and they start moving! Do you freak out? Well if you do, don’t because it is just a stick bug. They can camouflage into a stick to get away from birds or other predators. Also, maybe you’ll see a beautiful moth or butterfly then look at it again but this time you think you see a tiny flying monster with huge eyes. Actually, what you see is a moth or butterfly with fake eyes on it's wings. Some butterflies and moths have those to scare off predators.



                                                                          You Yourself

     Did you know when you are using your sense of sight your brain sees more than your eyes. Why does that happens, you ask, well we have blind spots at the edge of our eyes so we can’t see as much as our brain does. Those blind spots take up 15% of our view! Also 30% of our binocular vision is stone-blind. Like I said before, everything we see is an illusion, but there is also tons of optical illusions that we come by every day. Maybe, if you get knocked out you’ll see stars above your head.

     Whenever you are taking a walk do you ever feel that someone is watching you? Well it is most likely just face illusions, like in clouds or cities or even the landscape around you. When you go to an art museum, do you ever see a painting of a bunch of fruit shaped as a man? Well, that is just an purposely optical illusion made by us humans.

     Maybe just not you but animals can be optical illusions. Animals also camouflage into their surroundings to hide from predators or hunt down their prey. Some animals will make funny illusions like if birds will make a smiley face in the sky. Stingrays change into a different color to hide in the sand at the bottom of the ocean. Also a lot of other sea life does the same thing, change colors to blend in with their surroundings. Not just sea life but a lot of other animals too.

                                                  Different Kinds of Optical Illusions?

     Do you know any types of illusions? Well, their more than four of different kinds of optical illusions! The main one you may have heard of is cognitive illusions. They are like the big picture of illusions. All the other illusions are in the category of cognitive illusions and cognitive illusions are the category. Then there is ambiguous illusions which are pictures or objects that can be seen in more than one way such as Rubin’s vase for example. Also, distorting illusions are illusions that use different techniques to make objects of similar size, length or curves appear distorted. Paradox illusions are my favorite. They are pictures or objects that are completely impossible to exist.

                                                   Impossible and Secret Images

     As you heard befor Paradox illusions are impossible and Distorting illusions have “secrets” hidden within them. Distorting illusions use distortions of size, length, or curvature to change or to hide their “secrets.” Also, they use objects that our brain can not recognize. Plus, did you know that distorting illusions (information from the outside world, including sensations from the rest of the body) are constantly compared to a "virtual" world within the brain, which includes conceptual map of the body? I bet you didn't! Paradox illusions are a result of pictures or objects that cannot exist or are physically impossible. Paradox illusions are popular in works of art, such as those made by a famous artist, M. C. Escher (at Science City in Mr. E's Hotel.) His Waterfall illusion is a classic example of a paradox illusion.

                                                                 More Than One Way

     Ambiguous illusions are a big thing in our life. Ambiguous pictures make it past our eyes so they look normal to us. They can look like two different things. If your friend tells you something that can be interpreted in different ways, than that is called ambiguity. All through the world, even universe, there is tons of ambiguous illusions. Ambiguous illusions always have at least two potential ways of being seen, but they can certainly have more than that! Also, all aspects of an ambiguous illusion share the same space.

     Did you know that aspects of an ambiguous illusion share the same space? Well they do and sometimes it isn’t fun “dealing” with them. Also, sometimes ambiguous illusions are called bi-stable figures. Our brain sees things inside of pictures, but hardly are eyes do. Plus, your brain can only return one message at a time

                                                                 The Big Picture

     The main type of illusion is cognitive illusions. They are the heading and ambiguous, paradox, and distorting are the subheadings. These ones are even sometimes called “MinD Games.” All illusions occur when sensory DATA clashes with our assumptions about the way things are. Cognitive illusions make-up optical illusion which are based on the process through which the brain creates a visual world in one's mind using either or both these two sources: previous memory stored in it and the current presentation of the object in the environment. If there are any gaps once the percept is created, the brain attempts to fill in such gaps. The percept may not represent or interpret the real, physical measurement of the stimulus.

     Cognitive/optical illusions can use color, light and patterns to create images that can be deceptive or misleading to our brains. The information gathered by the eye is processed by the brain, creating a perception that in reality, does not match the true image. Different illusions occur because our brain is trying to interpret what we see and make sense of the world around us. Also, perception refers to the interpretation of what we take in through our eyes.

                                                                             The Brain

     There's a lot of things about our brain that we don’t know. We will soon find out about those ups and downs., but that is in a long time. We also know a lot about our brain like, for example, what it does and what it is for. We hope to know more. On the other hand, we know a lot about the human brain.



                                                Where Did That Come From?

     If you ever wondered how are brain works and what it sees? Well you’re in luck because I know the answer to that question. In our eyes we have something called blind spots. They are block out other things when you are staring at something else. An illusion is "a mismatch between the immediate visual impression and the actual properties of the object. Also, visual illusions occur due to properties of the visual areas of the brain as they receive and process information. Plus, an illusion is proof that you don't always see what you think you do because of the way your brain and your entire visual system perceive and interpret an image. Our brain is trying to make sense of the illusion so thats what makes it an illusion.

                                                           Facts About the Brain

     An illusion is "a mismatch between the immediate visual impression and the actual properties of the object. Also, Optical illusions firmly map our place within colors or dimensions of everyday life and sharpen our focus. Plus, did you know that optical illusions help us understand reality? Our brains can do 3D calculations that a nimble person may dash into a room and reach the other side by twisting, dodging and leaping without slowing down. Also, did you know the word “illusion” comes from the Latin word illudere, which means “to mock?” Plus, our brains work quickly to make a “whole” image from separate pieces.

     Put another way, optical illusions occur when our eyes send information to our brains that tricks us into perceiving something that does not match reality. In fact, clever artists can use these tendencies to trick our eyes and brains into seeing what’s not really there. As a matter of fact, optical illusions are images or pictures that we perceive differently than they really are. Did you know that scientists believe optical illusions are possible because our brains are so good at recognizing patterns and “seeing” familiar objects? Plus, optical illusions are visual trickery contrived to cajole our brains into reaching erroneous conclusions, based on erroneous visual assumptions.

     Did you know that, optical illusions can be highly social? An optical illusion suggests that the illusion arises because of some properties of the eye. Also, everything that enters the senses needs to be interpreted through the brain. Furthermore, although people popularly call some brain teasers "optical illusions," this might not be the best term for them, as scientists make a distinction between optical illusions and what they call visual illusions. The definition for illusion is: a distortion of the senses, revealing how the brain normally organizes and interprets sensory stimulation. While illusions distort reality, they are generally shared by most people. Also illusions trick our brain and eyes when seeing something that is not really there or something that is not really happening. Optical illusions make our minds sharper for it makes us think on what can be on that picture or how could that happened.

     Just as we measure the quality of goodness against a villain in a favorite movie, we can measure the character of reality against the quickness of optical illusions. Did you know that floaters are small specks, spots or shadowy shapes that seemingly float in your field of vision? To some, they look like a bright white snow or flashes of light. Plus, floaters are caused by tiny irregularities in the fluid that fills the eye. In other words, they're real. They become more common as one gets older. Although people popularly call some brain teasers "optical illusions," this might not be the best term for them, as scientists make a distinction between optical illusions and what they call visual illusions.

     For now we humans can easily target obvious assumptions that the brain will almost always make. Or we may, with further thought, change our minds, but we have to start somewhere. Optical illusions can use all our senses: taste, smell, hearing, sight, touch. An optical illusion will do anything it wants to do. In our life we are confronted by a deliberate illusions, it piques our curiosity. Although people popularly call some brain teasers "optical illusions" or optical illusions “brain teasers,” this might not be the best term for them. In the illusions we see or taste or hear or smell or even touch they all have to go through the brain for us to see, taste, hear, ect. Visual illusions occur due to properties of the visual areas of the brain as they receive and process information. Last but not least, optical illusions simply trick our brains into seeing things which may or may not be real.

     If you go to a magic show you should now find out the optical illusions they are using to trick your brain. So from now on, be careful!!
