B. SIDELL ABSTRACT -- Puffins, one of the few wing-propelled diving birds, are specialized into a specific niche. By balancing the optimization of their bodies for locomotion between the two media of air and sea water created a unique anatomy for a bird. The evolution of Auks, which includes the puffin, shows a mixture of characteristics similar to those of the ultimate diving bird, the penguin, and the large-winged flyers, such as the pelican. Wing-propelled diving has evolved numerous times in…

by the ratio of static pressure (P-P_∞) over the dynamic pressure of the free stream (1/2 ρU_∞^2) using the equation: C_p=(P-P_∞)/(1/2 ρU_∞^2 ) . The lift coefficient (C_L) is determined by lift force over the freestream dynamic pressure times the wing area (S) C_L=L/(1/2 ρU_∞^2 S). Aerofoil is one of the most…
As the early morning sun begins to rise, my nest is bathed nest is bathed in the warmth of its heavenly yellow glow. I straighten my legs and stretch out my wide grey wings. I look at my neighbouring nests to ensure that they’re all sleeping, then I take off into flight. I love going for a fly every morning and today was no exception. There is just something calming about soaring through the air. There’s the wind rushing past you, tickling all your individual feathers. It is just a wonderful way…
Storytelling, the ancient art of teaching, aided in the enlightenment of communities when Google and Youtube did not exist. People learned through what they heard, which made oral storytelling the best method of assimilation for them. They learned of the great wars fought by their ancestors, the bloodshed and carnage. They sat enchanted by tales of forbidden love, heartbreaking and raw. Little by little they listened and little by little they absorbed so much knowledge of the world they lived in…
average size for the genus. Each of the four wings of this dragonfly can move independently and are powered by powerful muscles. The wings normally beat 35 times per second and propel the dragonfly to speeds of 35 miles per hour. Dragonflies have a visual field of almost 360 degrees. The legs of dragonflies are not able to walk. The Warpaint Emerald Dragonfly is about 49-50 mm long in adults. The abdomen is approximately 38-47 mm and, the hind wing is about 31-37 mm long. This dragonfly has a…
of flight, Morrison develops the characters in their quest for identity. The novel opens with a man by the name of Robert Smith attempting to fly from the roof of a hospital. He wrote in a letter “I will take off from Mercy and fly away on my own wings” (Morrison 3). While this is clearly an act of suicide, the people may not have thought this to be true. “A few of the half…
The story of A Very Old Man with Enormous Wings by Gabriel Marquez presents an array of characters. Marquez distracts away from the main character, the angel, by mentioning so many characters but at the same time shines a theoretical light on the angel. The most interesting question is not that of why the narrator mentions so many others but why these characters treat the angel in such a horrid manner. Many factors lead to why exactly such evil practices ridicule the angel such as human doubt by…
