With Microscope, scientific community undertook to understand and explore those living organisms. 2) Microscope has helped us to understand the structure of living organisms. It helped us to understand and know that the microscope make it possible to see that living things are made of cells. Some organisms are made of a collection of similar cells that benefit from cooperating. Some organism’s cells vary greatly in appearance and perform very different roles in the organism. Since cells are considered as the most basic structure of any living organism and most of them are not visible to the naked eye however with the help of microscope, we have been able to see the enlarged images of the most basic functional unit of living organisms. In this way Microscope has helped us to explore the most basic level of any living organism’s existence in order to better understand its structure and functions. 3) Pathology is perhaps one of the fields which owe its existence to the in vention of microscope.

A medical doctor that specializes in pathology is called a pathologist. Pathologists are experts at interpreting microscopic views of body tissues. †(Medterms, 2008). From this definition of Pathology it is very clear that the microscope has greatly helped us to understand about the diseases and their underlying causes. Since diseases are caused due to chemical and other imbalances like virus attacks, bacterial attacks on human body which substantially weaken the immune system of the body therefore it is the microscope which first helped us to identify and study these microorganisms so that an external defensive mechanism may be developed to treat the diseases. 4) Microbiology is another field of science which greatly benefited from the contributions made by the Microscope. The scope of Microbiolog y extends to other living organisms also and as such carry a bigger scope than the field of pathology. Microscope has helped us to understand the bacteria, viruses and all other sorts of microorganisms. 5) Above all, Microscope has contributed towards helping us to understand about the chemical structures of the human body and other living organisms.

Summary Of The Days Of Good King - 2567 Words

In the days of good King Harry the Second of England—he of the warring sons—there were certain forests in the north country set aside for the King s hunting, and no man might shoot deer therein under penalty of death. These forests were guarded by the King s Foresters, the chief of whom, in each wood, was no mean man but equal in authority to the Sheriff in his walled town, or even to my lord Bishop in his abbey. One of the greatest of royal preserves was Sherwood and Barnesdale forests near the two towns of Nottingham and Barnesdale. Here for some years dwelt one Hugh Fitzooth as Head Forester, with his good wife and son Robert. The boy had been born in Lockesley town—in the year 1160, stern records say—and was often called Lockesley, or Rob of Lockesley. He was a comely, well-knit stripling, and as soon as he was strong enough to walk his chief delight was to go with his father into the forest. As soon as his right arm received thew and sinew he learned to draw the long bow and speed a true arrow. While on winter evenings his greatest joy was to hear his father tell of bold Will o the Green, the outlaw, who for many summers defied the King s Foresters and feasted with his men upon King s deer. And on other stormy days the boy learned to whittle out a straight shaft for the long bow, and tip it with gray goose feathers. The fond mother sighed when she saw the boy s face light up at these woodland tales. She was of gentle birth, and had hoped to see her son famousShow MoreRelatedReflection to the Book of Daniel and Revelation1749 Words   |  7 PagesNorthern Luzon Adventist College Artacho, Sison, Pangasinan __________ A Reflection Paper for the Subject Daniel and Revelation by: Jefferson Mendoza Daniel 1 Chapter Summary Daniel chapter 1 tells a story of a 4 young wise men named Daniel, Meshach, Shadrach and Abed-nego.

Several people turned around to stare at me or whispered under their breath to their friends. A few Just Just shook their heads or sighed. The social norm of refraining from talking on the phone during In a movie theater was an example of an explicit (In this case), Injunctive norm. The norm was explicit because during the movie previews, there was an advertisement that read â€Å"Please no talking on the phone or testing during the movie. † Through this ad, everyone In the theater was made directly aware of the social norm. Not talking on the phone In a movie is an injunctive norm because it is observed as the socially acceptable and polite thing to do. It is perceived that people approve of this behavior because it shows respect and consideration for those who want to watch the movie free of distractions or disturbances. This social norm is typically enforced through compliance. Even if a person might originally consider talking on the phone in a movie theater, they usually comply with the theater’s directly stated request to not do so in the pre-movie â€Å"Please do not talk on the phone or text during the movie† message.

Are we civilized Essay Example For Students

Are we civilized? Essay We are starting to witness the beginning of a new era. It is full of information and technology, and it will decide how the future is going to be. But despite all our new inventions and ideas that show us how were better off than the generations before us, have we grown in any other ways? Does being civilized only mean to become more advanced technologically, or does it apply to our moral foundation? It is very obvious that society has developed a lot in learning and technology. Today, we have inventions such as the stealth fighter, the home computer and nuclear powered power plants and naval vessels. Things that were imagined many years back have now become todays reality. Single machines now hold the jobs that used to take hundreds of men to accomplish by hand, so in this sense, we have become more civilized. On the other hand, not all of the inventions that have been developed from the technology world are used to do good deeds. Our great society has allowed the production of many weapons whose sole intention is to create mass destruction and to kill large amounts of life. Many people now live in constant fear of the use of these weapons, while others sit back and enjoy them for protection. We still have as many wars as we did in the past, but now the new technology used in them helps bring about more human casualties. An example of this would be Operation Desert Storm. I was a 23-year-old man, sent off to fight for the liberation of Kuwait and to kick the crap out of a bully named Saddam Hussein. I was the crewchief on an UH-60 Blackhawk helicopter assigned to the 1st Cavalry Division from Ft. Hood, TX. From the time the air war started to the 100 hours of hell we threw at the Iraqi Army, it was never more evident the role that technology played in decimating an enemy and b! reaking his will to win and survive. The pictures that my young eyes saw will forever be burned into memory. Technology was a teacher of pain and suffering, but it was also a savior in helping bring home the lives of many young men who might of not come back in previous wars. Besides the wars, society really has yet to understand other people. Prejudice is alive and burning in the hearts of many throughout our society. Many hate groups are still around today, as they were hundreds of years ago, and many new groups are starting to form and become active. Oklahoma City felt the wrath of some very passionate people who were trying to avenge the loss of comrades to the Federal Government. Many innocent people were killed, and it all boils down to beliefs and ideas. Racism still has its hand around the throats of many in our society as well. It seems that some of the worst racists in our society are the ones who  say theyre not racist, but on the inside they really are. These are the people who say theyre not racist, but they dont hire the East Indian employee who was the most qualified of the candidates. They coach the all white basketball team. They fight over the red and blue colors of bandannas worn around their heads. The worst part is, it d! oesnt even phase them when they are doing it. In the past when our country was just starting to be formed, there were many prejudices just because people were different. Now over a century later, people havent changed much, which makes me wonder if we really have become civilized yet. .u27648514b062b6168c5fa8a0b0c135bb , .u27648514b062b6168c5fa8a0b0c135bb .postImageUrl , .u27648514b062b6168c5fa8a0b0c135bb .centered-text-area { min-height: 80px; position: relative; } .u27648514b062b6168c5fa8a0b0c135bb , .u27648514b062b6168c5fa8a0b0c135bb:hover , .u27648514b062b6168c5fa8a0b0c135bb:visited , .u27648514b062b6168c5fa8a0b0c135bb:active { border:0!important; } .u27648514b062b6168c5fa8a0b0c135bb .clearfix:after { content: ""; display: table; clear: both; } .u27648514b062b6168c5fa8a0b0c135bb { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u27648514b062b6168c5fa8a0b0c135bb:active , .u27648514b062b6168c5fa8a0b0c135bb:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u27648514b062b6168c5fa8a0b0c135bb .centered-text-area { width: 100%; position: relative ; } .u27648514b062b6168c5fa8a0b0c135bb .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u27648514b062b6168c5fa8a0b0c135bb .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u27648514b062b6168c5fa8a0b0c135bb .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u27648514b062b6168c5fa8a0b0c135bb:hover .ctaButton { background-color: #34495E!important; } .u27648514b062b6168c5fa8a0b0c135bb .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u27648514b062b6168c5fa8a0b0c135bb .u27648514b062b6168c5fa8a0b0c135bb-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u27648514b062b6168c5fa8a0b0c135bb:after { content: ""; display: block; clear: both; } READ: Showing the connection between EssayDemocracy is also something that has played a big part in our journey to become civilized. A democracy in my words is where the people who choose to live under it run the government. And to have a true democracy, everyone must vote! People vote to exercise their democratic rights. If only 70% vote, then 70% control 100% of the government. Voting without adequate understanding and choosing candidates for the wrong reasons are symptoms of voting for the sake of voting and not taking an active interest in how our country is run. Instead of making an effort to understand issues and party fundamentals, too many ignorant people actually base t heir decisions on what the candidates say. The result is that everybody feels burned by the government, never realizing that he or she could have tipped the election simply by paying attention. Another problem with our vision of democracy is the structure and size of it. It seems everybody is always trying to help somebody get something ! for nothing. This just creates class envy and finger pointing. I personally believe the governments goal is to keep us divided as a country so we will fight amongst ourselves rather than pay attention to whats going on. So, is this civilized? I think not. Technically though, if you want to look at it really hard, we have become a civilized society. We can now travel across the country in a few hours or send someone an email. Most people believe that to become civilized you need to create new inventions and spend lots of money on social programs, making most people think that they are becoming better off and are more civilized. But our nature has not become more civilized. There are still wars, hatred, and acts of violence. Maybe it is more important to grow in this area than the other is. So in reality, were not as civilized as we think we are.
