When we look at the world around us, we see it in vivid colors. Those colors, including blue, red, yellow and green, are a part of our lives and we naturally assume that they exist in the world on the outside. The fact of the matter is that color actually is only how we perceive the world according to the way that light reaches our eyes. Depending on how the light reacts to the sensitivities of our light receptors, it makes a difference in how we see things. This science of seeing color is known as colorimetry and it truly [More]
Art is something that has been a part of our lives for millennia and some of the art that was available thousands of years ago still fascinates people down to this day. From time to time, however, something a little different others on the scene and it quickly becomes popular. That is the case with 3-D art, which has really gained in popularity over the past century or so. Three-dimensional street art has been in existence since the late 1800s, and at that time, there were actually several hundred people in the UK making a living by drawing on the [More]
There are so many different things that come together to cause us to see the world as we see it. For one, everything that we see has to do with light and the various ways that light bounces off objects and reaches the retina in our eyes. Additionally, it has to do with the way that the eye processes the information that we see, and it can really make a difference in what we see as well. One of the more interesting things that need to be considered when it comes to our vision is perspective. We have two eyes [More]
Many of us enjoy a good magic trick but in reality, they often involve some type of sleight-of-hand that simply tricks the eyes into seeing something that really isn’t there. That isn’t the case with every trick, however, and some of them might actually stun you with their ability to do something unusual. That is sure to be the case with this coin trick that you will try over and over again. In order to do this coin trick, you need a quarter, or you can use any other coin, and a regular coat hanger. The trick is to balance [More]
When most of us think about the human organ that is responsible for sight, we automatically think about the eyes. If you think that your vision is completely focused on your eyeballs, however, you’re absolutely wrong. As you view something, the eyeball focuses the light on the retina and then the rods and cones are affected by the light. After that takes place, then something rather amazing happens that most people fail to consider. The information that is gathered by our eyes travels along the optic nerve and enters into the brain. It is then that it is interpreted by [More]
There is something that all of us must deal with on a daily basis and, regardless of how we might try to avoid it, it is inevitable that it is part of our lives. I’m talking about the physical laws of the universe, something that affects us and we never really give it much thought. One of those natural forces is gravity, a type of phenomena that causes mass to be brought toward one another. Gravity can be felt on a universal scale, such as when galaxies are held together or even clusters of galaxies seem to be held together. [More]
People can use their hands in rather remarkable ways and they are a part of the body that really is quite underrated. We use our hands to interact with the world around us and they can either be soft or harsh, depending upon the need. As you are about to see, the hands can also be used in a rather artistic way and it may be one that you had never considered before. The pictures that you see in this video may look like various things from nature, including a rabbit, bird or even soldiers. If you take a closer [More]
When most of us think about optical illusions, the first thing that tends to come to mind is something that is drawn on a piece of paper and tricks the mind as well as the way. When they are done properly, they cause us to see something that isn’t there or perhaps to perceive something that is visually impossible. In any case, they can be quite interesting to see and even to study. Sometimes, it is not only possible to look at one of these optical illusions on paper but it is possible to create more than real life. That [More]
When we were in school, we may have done a wide variety of science experiments. Some of them were to show how we interacted with the world around us and others may have been so that we could see the elements which were sometimes unseen. Yet another type of experiment, and perhaps a favorite for most people, involved the way that the mind can trick the body into believing that it is seeing something that doesn’t actually exist. Although it is not always considered a science experiment, these types of optical illusions can certainly be a lot of fun to [More]
When we look at anything in the world around us, we likely have thought that what we see is actually what exists. In many cases, it is true to a limited extent. For example, color may not actually exist in the real world but rather, it is how our brain interprets the light that enters into the retina. In addition, everything that we see is upside down, so the world may look rather strange, indeed. Another effect that can certainly change the way that we view anything is known as anamorphosis. It involves the perspective that an individual has when [More]
When you see the world around you, you perceive it as being full of color and variety. The fact of the matter is, however, color is only an illusion and it does not exist in the real world. What does exist is light, and it depends upon how the light is reflected off of an object as to how we see the color that truly exists. For example, when the light reflects off of an Apple, the wavelengths that appear red reaches the eye and we see it as being red. Would you believe me if I told you could [More]
There are many processes that take place in the human body on an ongoing basis and in most cases, we don’t even think about them. One of those is the sense of sight and we take in information from the world around us in order to give us the guidance we need to do anything from picking up a glass of water to driving an automobile. Much of it even takes place behind the scenes without even having to think about it. What many people don’t know is that the eye is an amazing organ that can take in a [More]
