The telescope is an important astronomical tool that gathers and focuses electromagnetic radiation. Telescopes serve to both increase the angular size and the brightness of objects. When we speak about telescopes we are usually referring to optical telescopes‚ but many other types of telescopes also exist for other spectrum of electromagnetic radiation. It is unclear as to who it was that actually invented the telescope but Galileo Galilei is credited as being the first to use a telescope for

Can Art Change the Way We View the World? Susan Agee Classics in Philosophy of Art - P346 Gregory Steel Fall 2012 For centuries‚ art has been interwoven throughout the history of mankind. From primitive carvings on cave walls and ancient Egyptian hieroglyphs‚ to the Sistine Chapel and the Mona Lisa‚ artistic creations have enthralled the human race. Art may be a window to the creator’s world; it has potential to instill desire in the viewer to do something they have never done‚ be somewhere they

Visual Deception Visual phenomena or what we normally call as ‘Optical Illusion’ involves visual deception. A wide range of optical illusions happen in our day to day lives‚ like seeing a rainbow after a rainy day or even while staring at clouds; In this phenomenon‚ the human brain tends to develop different pictures to interpret the shape‚ curve‚ and size of the clouds. Optical illusions are just cases of errors in judgment; they do not physically exist. Our eyes capture light from

Executive Summary Optical fibres are being increasingly used in the telecommunications industry. They are slowly replacing the conventional copper cables due their superior ‘data transmission’ properties. They transmit data via light pulses within glass or plastic strands. Fibre optics fit the material requirements for good data transmission since they are ability to transmit and preserve quality of signals‚ durable and cost-effective. Some of the current materials employed within the industry

The spinning dancer illusion Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception is the process of organizing and interpreting sensory information‚ enabling us to recognize meaningful objects and events. My lab/activity is the spinning dancer illusion which was originally created by nobuyuki kayanara. The illusion was related to bistable perception in which an ambiguous 2-dimensional figure can

Optical Storage Devices • An optical disk is a high-capacity storage medium. An optical drive uses reflected light to read data. • To store data‚ the disk’s metal surface is covered with tiny dents (pits) and flat spots (lands)‚ which cause light to be reflected differently. • When an optical drive shines light into a pit‚ the light cannot be reflected back. This represents a bit value of 0 (off). A land reflects light back to its source‚ Representing a bit value of 1 (on)

An optical illusion (also called a visual illusion) is characterized by visually perceived images or views that can differ a ton from objective reality. Optical illusions have been around for centuries‚ teaching us that you shouldn’t fully trust your senses due to that we can easily be tricked. However‚ optical illusions can help us learn how easy it is to trick our brain to see an object that seems real but is really not. An example of a well-known visual illusion would be the “Ames Room”.

First Impression It was a weary afternoon of Sunday; everyone was in full used of their energy. As I sat on the terrace of my classmate’s house‚ the warm breeze of the air tapped my body that was getting weaker moment by moment due to the nervousness that I felt whenever I remembered that sooner I will see him in front of my face. He was a friend of mine but I never had a chance to see him since we got in touch with each other through exchanging of messages. Cellphone is the means of our communication
