  • Bodily Eye
    838 words
    In Plato's "The Allegory of the Cave", he suggests that there are two different forms of vision, a "mind's eye" and a "bodily eye". The "bodily eye" is a metaphor for the senses. While inside the cave, the prisoners function only with this eye. The "mind's eye" is a higher level of thinking, and is mobilized only when the prisoner is released into the outside world. This eye does not exist within the cave; it only exists in the real, perfect world. The "bodily eye" relies on sensory perceptions ...

These sources are: the sun, carbon arcs, mercury arcs, and black ligh...

I effortlessly enter my pervious pastel palace, but the voyage to my room is an uphill battle; it is quite an insurmountable quest. The trek to my cell consists of a frozen spiral staircase. It is not smooth and slippery, though, but rocky and perilous. The portal lies beyond the staircase... I force my way through the abrasive ...
  • Of The Differences In Eye
    291 words
    Eye is the organ of sight. It is our most important organ for finding out about the world around us. We use our eyes in almost everything we do -- reading, working, watching movies and television, playing games, and countless other activities.

Yet the eye can see objects as far away as a star and as tiny as a grain of sand. Th...

  • Hand Which

    Darkness, first published in 1816 I had a dream, which was not all a dream. The bright sun was extinguish'd, and the stars Did wander darkling in the eternal space, Rayless, and pathless, and the icy earth Swung blind and blackening in the moonless air; Morn came and went-and came, and brought no day, And men forgot their passions in the dread Of this their desolation; and all hearts Were chill'd into a selfish prayer for light: And they did live by watch fires-and the thrones, The palaces of cr...

    A city at night I had finally reached my destination, Hong Kong. As I strolled out of the clustered subway my eyes glittered with excitement, my two lengthy hour journey was over. The lights sparkled magnificently like glitter dust in an assortment of colours in the sky. The mayhem traffic on the narrow roads resembled a war zone.

  • Eye The Picture
    657 words
    How do we see? Most people would just say that we see with our eyes and this is true but it is also more complicated than that. In some ways the eye is a bit like a camera that sends images to our brain but it is very sensitive and can be easily damaged. The eye itself is a very compact and complex apparatus. The eye is only around 25 mm wide and deep and slightly less in height. A complex set of 6 muscles (known as the extra ocular muscles) attached to the outside of the eye help it to move in ...

  • Light Through A Lens
    963 words
    Have you ever looked up to the sky at night, and wondered what stars look like up close? Have you ever wondered how astronomers take pictures of other planets with such detail? Although the human eyes are superb detectors, they cannot see extremely faint objects or fine details on distant objects. For example, you would not be able to read the print on your skateboard magazine when it is on the other side of a dimly lit room. However, if you had something that would collect more light than your ...
