Device to Overcome Sense of Sight and Hear
SENSE OF SIGHT…. The eyes are sensory organs. They keep the brain updated with information about is what happening around the body. Both contain millions of tiny sensors that send messages along nerves to the brain. Sensors in the eyes respond to light and, through the brain, let us see the world. Sensors in the skin respond to touch and allows us to feel. * * * *
The seeing eye… Light enters the eye through the clear cornea. It then passes through the pupil and is focused by the lens on the retina. This thin layer covers the back of the eye and contains cells that are sensitive to light. When light hits the cells, they send signals to the brain. There, the signals are turned into pictures so we can see.
Telescope... A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 17th century, using glass lenses. They found use in terrestrial applications and astronomy.Within a few decades, the reflecting telescope was invented, which used mirrors. In the 20th century many new types of telescopes were invented,
including radio telescopes in the 1930s and infrared telescopes in the 1960s. The word telescope now refers to a wide range of instruments detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors.
History… The earliest recorded working telescopes were the refracting telescopes that appeared in the Netherlands in 1608. Their development is credited to three individuals: Hans Lippershey and Zacharias Janssen, who were spectacle makers in Middelburg, and Jacob Metius of Alkmaar.[4] Galileo heard about the Dutch telescope in June 1609, built his own within a month,[5] and greatly improved upon the design in the following year.
