The final illusion is the Checker Shadow Illusion. This illusion shows two squares that are the exact same color. You mind thinks that the squares are two different colors, but your brain thinks that because of their background. It mainly has to do with how our brain interprets the drawing. The image is described as two specific checker squares, labeled A and B, are drawn on a grid. The checker square that is labeled “B” is being cast over by a shadow from a large cylinder. We are expecting the cylinder to cast the shadow onto the checkerboard. Because we are used to making sense of shadows in real life, we become aware of the shadow, and we think that we know how to interpret it. However, the person who made this illusion, Edward H. Adelson, …show more content…
Optical illusions reveal the way that your vision alters images before you are even aware that the alternation is happening. People made optical illusions before anyone could even understand how they work. Today, the study of nervous system, also known as neuroscience, have pinpointed the process in your eyes that fool your brain in order to create the optical illusion. Some optical illusions are still in need of an explanation. We use moving optics, light, in order to make a general illusion so that a random object would appear to become an object of our …show more content…
The first cone cell responds the most to long lightwaves. The first cone cell can receive lightwaves almost 560 nanometers away. This is usually labeled L for "Long”. the second type of cone cell responds to medium-length lightwaves, about 530 nm away. This is labeled M for “medium”. The final cone cell is the cell that receives the shortest lightwaves. The third cone cell can only receive lightwaves that are a very short distance away, only 420 nm. These are labeled as “short”, or just S. Colors that we see are just reactions of the cone cells in your eyes. Take red, for example. The way that we see the color red is because the L cone cells are stimulated much more than the M cones. We see yellow because the L cone cells are stimulated just slightly more than the M cone cells. Blue and violet are similar to comprehend. They are seen when the S cone cells are stimulated more than the M and L cone cells. These cone cell have to work together to see a whole spectrum of colors. If you look at an image, the light would pass through your lens to the retina, which is where the cone cells are. It is their job to interpret and distinguish the many different colors in that image. This whole process takes a little more than 50 milliseconds to complete. The original time that it takes to process an image is 10 milliseconds, but that is way too long to comprehend images.

Diseases and Causes

...Color blindness or color vision deficiency is the inability or decreased ability to see color, or perceive color differences, under lighting conditions when color vision is not normally impaired. "Color blind" is a term of art; there is no actual blindness but there is a fault in the development of one or more sets of retinal cones that perceive color in light and transmit that information to the optic nerve Muscular dystrophy (MD) is a group of muscle diseasesthat weaken the musculoskeletal system and hamper locomotion.[1][2] Muscular dystrophies are characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells andtissue.[3] Blood disorders can lead to poor blood clotting and continuous bleeding. The disorders can result from defects in the blood vessels or from abnormalities in the blood itself, such as in blood clotting factors or in platelets. Ichthyosis (plural ichthyoses) is a heterogeneous family of at least 28,[1] generalized, mostly genetic skindisorders. All types of ichthyosis have dry, thickened, scaly or flaky skin.[1] In many types there is cracked skin,[2] which is said to resemble the scales on a fish; the word ichthyosis comes from the Ancient Greek ιχθύς (ichthys), meaning "fish.

Short Stories

...Bienvenido Santos: The Day The Dancers Came AS soon as Fil woke up, he noticed a whiteness outside, quite unusual for the November mornings they had been having. That fall, Chicago was sandman's town, sleepy valley, drowsy gray, slumberous mistiness from sunup till noon when the clouds drifted away in cauliflower clusters and suddenly it was evening. The lights shone on the avenues like soiled lamps centuries old and the skyscrapers became monsters with a thousand sore eyes. Now there was a brightness in the air land Fil knew what it was and he shouted, "Snow! It's snowing!" Tony, who slept in the adjoining room, was awakened. "What's that?" he asked. "It's snowing," Fil said, smiling to himself as if he had ordered this and was satisfied with the prompt delivery. "Oh, they'll love this, they'll love this." "Who'll love that?" Tony asked, his voice raised in annoyance. "The dancers, of course," Fil answered. "They're arriving today. Maybe they've already arrived. They'll walk in the snow and love it. Their first snow, I'm sure." "How do you know it wasn't snowing in New York while they were there?" Tony asked. "Snow in New York in early November?" Fil said. "Are you crazy?" "Who's crazy?" Tony replied. "Ever since you heard of those dancers from the Philippines, you've been acting nuts. Loco. As if they're coming here just for you. Tony chuckled. Hearing him, Fil blushed, realizing that he had, indeed, been acting too eager, but Tony had said it. It felt that way--as...

Onehundredyearsofsolitude

...Gabriel Garcia Marquez One Hundred Years of Solitude Chapter 1 MANY YEARS LATER as he faced the firing squad, Colonel Aureliano Buendía was to remember that distant afternoon when his father took him to discover ice. At that time Macondo was a village of twenty adobe houses, built on the bank of a river of clear water that ran along a bed of polished stones, which were white and enormous, like prehistoric eggs. The world was so recent that many things lacked names, and in order to indicate them it was necessary to point. Every year during the month of March a family of ragged gypsies would set up their tents near the village, and with a great uproar of pipes and kettledrums they would display new inventions. First they brought the magnet. A heavy gypsy with an untamed beard and sparrow hands, who introduced himself as Melquíades, put on a bold public demonstration of what he himself called the eighth wonder of the learned al-chemists of Macedonia. He went from house to house dragging two metal ingots and everybody was amazed to see pots, pans, tongs, and braziers tumble down from their places and beams creak from the desperation of nails and screws trying to emerge, and even objects that had been lost for a long time appeared from where they had been searched for most and went dragging along in turbulent confusion behind Melquíades’ magical irons. “Things have a life of their own,” the gypsy proclaimed with a harsh accent. “It’s simply a matter of waking up their souls.” José...

...THE B L A C K SWAN The HIGHLY I mpact IM of the PROBABLE Nassim Nicholas Taleb U.S.A. $26.95 Canada $34.95 is a highly improbable event with three principal characteristics: It is unpre­ dictable; it carries a massive impact; and, after the fact, we concoct an explanation that makes it appear less random, and more predictable, than it was. The astonishing success of Google was a black swan; so was 9 / 1 1 . For Nassim Nicholas Taleb, black swans underlie almost everything about our world, from the rise of religions to events in our own personal lives. A BLACK SWAN Why do we not acknowledge the phenomenon of black swans until after they occur? Part of the answer, according to Taleb, is that humans are hardwired to learn specifics when they should be focused on generalities. We concentrate on things we already know and time and time again fail to take into consideration what we don't know. We are, therefore, unable to truly estimate oppor­ tunities, too vulnerable to the impulse to simplify, narrate, and categorize, and not open enough to rewarding those who can imagine the "impossible." For years, Taleb has studied how we fool our­ selves into thinking we know more than we actually do. We restrict our thinking to the irrelevant and inconsequential, while large events continue to surprise us and shape our world. Now, in this reve­ latory book, Taleb explains everything we know about what we don't know. He offers...

...C h a p t e r 1 Prewriting GETTING STARTED (OR SOUP-CAN LABELS CAN BE FASCINATING) For many writers, getting started is the hardest part. You may have noticed that when it is time to begin a writing assignment, you suddenly develop an enormous desire to straighten your books, water your plants, or sharpen your pencils for the fifth time. If this situation sounds familiar, you may find it reassuring to know that many professionals undergo these same strange compulsions before they begin writing. Jean Kerr, author of Please Don’t Eat the Daisies, admits that she often finds herself in the kitchen reading soup-can labels—or anything—in order to prolong the moments before taking pen in hand. John C. Calhoun, vice president under Andrew Jackson, insisted he had to plow his fields before he could write, and Joseph Conrad, author of Lord Jim and other novels, is said to have cried on occasion from the sheer dread of sitting down to compose his stories. To spare you as much hand-wringing as possible, this chapter presents some practical suggestions on how to begin writing your short essay. Although all writers must find the methods that work best for them, you may find some of the following ideas helpful. But no matter how you actually begin putting words on paper, it is absolutely essential to maintain two basic ideas concerning your writing task. Before you write a single sentence, you should always remind yourself that 1. You have some valuable ideas to tell your reader,...

New Moon

...New Moon By Stephenie Meyer Summary When the Cullens, including her beloved Edward, leave Forks rather than risk revealing that they are vampires, it is almost too much for eighteen-year-old Bella to bear, but she finds solace in her friend Jacob until he is drawn into a cult and changes in terrible ways For my dad, Stephen Morgan— No one has ever been given more loving and unconditional support than I have been given by you. I love you, too. These violent delights have violent ends And in their triumph die, like fire and powder, Which, as they kiss, consume. Romeo and Juliet, Act II, Scene VI PREFACE I FELT LIKE I WAS TRAPPED IN ONE OF THOSE TERRIFYING nightmares, the one where you have to run, run till your lungs burst, but you can't make your body move fast enough. My legs seemed to move slower and slower as I fought my way through the callous crowd, but the hands on the huge clock tower didn't slow. With relentless, uncaring force, they turned inexorably toward the end—the end of everything. But this was no dream, and, unlike the nightmare, I wasn't running for my life; I was racing to save something infinitely more precious. My own life meant little to me today. Alice had said there was a good chance we would both die here. Perhaps the outcome would be different if she weren't trapped by the brilliant sunlight; only I was free to run across this bright, crowded square. And I couldn't run fast enough. So it didn't matter to me that we were surrounded...
