Sonar

Over time, society continues to grow and become more complex. Today, it is more complex than ever. In my experience, the world is immensely fast-paced and it is easy to get caught in the moment with so much going around, and all the tasks that need to get done. However, as a sociology student I have realized the importance of pausing and looking around myself. This includes temporally, situationally, and location. The reason is that to gain a better understanding of my own biography, it is…

In 1962 the world was extremely close to a nuclear war, but thanks to one man the horror never happened. The crisis was known as the Cuban Missile Crisis, when the Soviet Union sent four nuclear submarines armed with torpedoes into the seas around Cuba. The future of the world was in doubt. Naturally, the US did not like the dangerous Soviets so close to the US, so President Kennedy decided to set up a blockade around Cuba. He did this by deploying the US Navy, the world’s largest navy. He sent…

Should vampire bats be killed or protected and research? Vampire bats could lead to many technological and biological breakthroughs, but they can spread rabies and attack humans and cattle. These creatures should be studied, not put to death. This is because they help us through many technological and biological discoveries as mention in Los Angeles Times’ article “ Vampire bat debate: To kill or not to kill” on paragraph 15,” Bats have developed a radar system that can distinguish the tiniest…

pushed through all of the darkness by playing the harmonica and singing. Stevie also plays the drums and the piano. By the age of 21, the world knew him as a musical genius. One positive side for Stevie’s blindness is that he trained himself to use sonar. I quote,” I was happy being blind, and I thought it was a gift from God.” [(Beyer, Mark T. Rock & Roll Hall of Famers Stevie Wonders. 1st ed. NewYork:…

the central Atlantic ocean. After World War I was over, echo-sounding devices were invented. These “primitive sonar systems” began to measure the depth of the ocean by noting how long it took for a sound generated from a ship to bounce off the ocean floor and come back. These signals showed scientists that the floor of the ocean was much more rough than they had imagined before. These sonar measurements showed us the ruggedness of the underwater chain of mountains that became known later as the…

It has been known for many years that bats use echolocation to navigate and find prey in the dark. What has been left unanswered is how that when bats are flying together are not found running into each other due to interference of sound waves from their neighbours. It is known that bats do not have any problems with this interference because bats have been observed flying in swarms and capturing prey with not a problem. What scientists are now trying to discover is how the bats can get around…

electrograph. In 1887 a scientist by the name of August Waller created the electrograph, which tracked the minute electrical currents in the heart. During World War Two, the field of echocardiography evolved greatly due Inge Edler and Hellmuth Hertz using a sonar ultrasonography device from a submarine and listened to Hertz heart beats. In 1960 Edler invented the first echocardiograph. Heart monitors and pulse detectors were preceded by the electrograph. X-rays and radiation are used for…

I had my hand on the reel, I moved the rod back and then forward while I let go of the line. The crankbait softly hit the surface of the water. I waited a few seconds, suddenly I saw my line move so I jerked my pole upward and yelled, “fish on”! My dad quickly grabbed the net to land the fish. The slimy, brown, 4lb fish was my first catch of the day. Last summer my dad and I went to Green Bay, WIsconsin for a fishing trip. This was my first time going there so I didn't know what to expect. The…

C. Investigation It is the aim of this investigation to determine whether World War II contributed to a major advancement in technology. The research task was conducted using both primary sources, like letters and advertisements from the time of WWII, as well as secondary sources, namely research papers and information from a top World War II Museum. These resources were analysed and information extracted in order to answer the investigative question. The importance of the investigation is to…

mysterious uncle will finally appear and leave me a handsome inheritance! I hope Santa knows I’ve been a good girl *looks innocently* I know, only too well, that these are much too ambitious dreams for a single year, but as the Spanish would say, soñar no cuesta nada, to dream costs nothing. So here goes, a bucket list of travel adventures I’d…
