History Of the Kaleidoscope invented in 1816 By David Brewster
both eyes had a very sharp kaleidoscope then lost vision?
This has happened a couple of times i see like a ring of what is a kaleidascope but could still see in the center, it is moving..but the last time i lost my vision everything went gray for about 20 minutes any ideas ?
You should definitely go to a physician or an ophthalmologist to get them look into it as soon as possible! Any type of vision loss (e.g. blindness, blurred vision, double vision, etc.) is a symptom of great concern. Many of the causes are very serious medical conditions. Certain types of vision changes can be a medical emergency where delay can lead to loss of sight (e.g. for causes such as glaucoma, eye injury, retinal detachment) or loss of life (e.g. for causes such as stroke, TIA, etc.). Even transient or temporary blindness or loss of vision cannot be ignored because it can result from serious conditions such as stroke, TIA, hypertension or epilepsy. Temporary loss of vision that persists for at least several minutes can be a sign of interruption of blood flow to the eye. Temporary visual loss can be followed by visual loss that is permanent. By analogy, a few minutes of chest pain can be a sign of an impending heart attack, and the importance of contacting your doctor in this situation seems obvious. Not all causes of temporary visual loss are serious though. In fact, migraine is the leading cause of temporary visual loss (even when not accompanied by headache) and vision almost always returns to normal with migraine. However, never assume anything. You should go to a doctor ASAP.
How is a kaleidoscope like a teacher?
In what ways is a kaleidoscope similar to a teacher? What qualities do they share?
"A kaleidoscope is a cylinder with mirrors containing loose, colored objects such as beads or pebbles and bits of glass. As the viewer looks into one end, light entering the other creates a colorful pattern, due to the reflection off of the mirrors. Coined in 1817 by Scottish inventor Sir David Brewster, "kaleidoscope" is derived from the Ancient Greek καλός (kalos), "beautiful, beauty", εἶδος (eidos), "that which is seen: form, shape" and σκοπέω (skopeō), "to look to, to examine", hence "observer of beautiful forms.
A Kaleidoscope operates on the principle of multiple reflection, where several mirrors are together. Typically there are three rectangular lengthwise mirrors. As the tube is rotated, the tumbling of the coloured objects presents varying colours and patterns. Arbitrary patterns shows up as a beautiful symmetrical pattern."
A teacher is not really an observer of beautiful forms unless you stretch the point to say that the teacher observes the student using the new information and moving ahead as a learner. It is easier to use an arts teacher in the comparision.
The second paragraph of the definition has a possibility. The kaleidoscope operates on multiple reflection with several mirrors together. A good teacher has to use multiple techniques to reach students who have various learning strategies, such as visual, auditory, and kinesthetic learners. A teacher also uses multiple teaching strategies such as lecture, differential learning and flexible grouping, and one-on-one work. So the kaleidoscope uses multiple mirrors and the teacher uses multiple techniques and multiple strategies.
