Sleep is defined as a natural…

sit idle on your couch staring into a picture box, your brain is telling your heart to continue to beat and pump blood through your veins, your brain is also processing the images and their colors of the TV. Light enters the eye upside down and the retina transforms the light into nerves signals for the brain. The brain then turns the image right side up and tells us what we are seeing, and all of this happens within a matter of nano seconds. The brain commands the body but in order for the…

falls. I sleep little and I sleep poorly, dreaming of a generic flowery wood, horses nearby, his mother in a sundress, a Sunday-morning feel, when he shouts, waking me from my siren world: “Dad! Dad!

When we discussed the Kinetoscope in class last Thursday, I was intrigued by the design of this invention, but could not fully make sense of how it functions just by looking at pictures of it. An interior view of the Kinetoscope shows film wrapped around a number of wheels below an eyepiece, leading through another series of wheels that create vertical parallel rows of film, and running back towards the eyepiece. Although the film appears to pass beneath the eyepiece located at the crown of the…

leaving at 8:00 pm eastern time to 10:20 pm pacific time, I could not read over my business materials. The flight was not full, yet the flight attendant did not move me to another seat so I could read. The day before the guy had eye surgery for a retina problem and had to strain his eyes in the dark, because the flight attendant refused to move me. This is very unacceptable considering that he had been a Delta Sky Miles member since…

With close reference to two symbols, show how F Scott Fitzgerald uses symbolism to comment on the shallowness and corruption at the heart of American society.
