What is Illusion?


Illusion, a misrepresentation of a real sensory stimulus it is, an interpretation that contradicts objective reality as defined by general agreement. For example, a child who perceives tree branches at night as if they are goblins may be said to be having an illusion.
Illusions distort one's senses. Most illusions tend to deceive the eyes, ears and skin, while there are some illusions that may distort perception due to changes in internal body structures. The three main types of illusion include optical illusions, auditory illusions, and tactile illusions. Epicharmus and Protagorus invented optical illusions in 450 B.C.An illusion occurs when the auditory component of one sound is paired with the visual component of another sound, leading to the perception of a third sound.

Evolution of Aircrafts

Since that fateful day in December of 1903, airplane design has changed dramatically. The Wright Brothers built a biplane with two propellers that were chain-driven by a gasoline motor. Our dependence on air travel over the years has forced airplane design to catch up with the times. On December 17, 1903, Wilbur and Orville Wright made four brief flights at Kitty Hawk with their first powered aircraft. The Wright brothers had invented the first successful airplane. The Wrights used this stopwatch to time the Kitty Hawk flights. Aircrafts have evolved so much from the initial days. From 2 seater to the latest air bus type, they have come a long way.  The history of aviation extends for more than two thousand years, from the earliest forms of aviation such as kites and attempts at tower jumping to supersonic and hyper-sonic flight by powered, heavier-than-air jets. Kite flying in China dates back to several hundred years BC and slowly spread around the world. Sir George Cayley...

How Electric Current is formed?

How Electric Current is formed? Have you ever wondered how Electric Current is formed? Generally, the flow from one point to another through a medium is called a current. When an electric charge moves from one point to another inside a conductor or a semiconductor, it is actually conducting electric current. Electric charge carriers are micro particles that conduct the electricity. They can be protons, electrons, holes or ions depending on their availability in the conducting material.  Normally electrons and holes are responsible for conducting electricity. This process occurs when a Voltage or a Potential Difference is applied at the two ends of a conductor or a semiconductor. Thus Electric Current is formed when a Voltage of Potential Difference is applied at the two ends of a conductor or semiconductor, i.e. when a closed circuit is formed.
