Biography of Robert Hooke, the Man Who Discovered Cells

Biography of Robert Hooke, the Man Who Discovered Cells Robert Hooke (July 18, 1635–March 3, 1703) was a 17th-century natural philosopher- an early scientist- noted for a variety of observations of the natural world. But perhaps his most notable discovery came in 1665 when he looked at a sliver of cork through a microscope lens and discovered cells. Fast Facts: Robert Hooke Known For: Experiments with a microscope, including the discovery of cells, and coining of the termBorn: July 18, 1635 in Freshwater, the Isle of Wight, EnglandParents: John Hooke, vicar of Freshwater and his second wife Cecily GylesDied: March 3, 1703 in LondonEducation: Westminster in London, and Christ Church at Oxford, as a laboratory assistant of Robert BoylePublished Works: Micrographia: or some Physiological Descriptions of Minute Bodies made by Magnifying Glasses with Observations and Inquiries Thereupon Early Life Robert Hooke was born July 18, 1635, in Freshwater on the Isle of Wight off the southern coast of England, the son of the vicar of Freshwater John Hooke and his second wife Cecily Gates. His health was delicate as a child, so Robert was kept at home until after his father died. In 1648, when Hooke was 13, he went to London and was first apprenticed to painter Peter Lely and proved fairly good at the art, but he left because the fumes affected him. He enrolled at Westminster School in London, where he received a solid academic education including Latin, Greek, and Hebrew, and also gained training as an instrument maker. He later went on to Oxford and, as a product of Westminster, entered Christ Church college, where he became the friend and laboratory assistant of Robert Boyle, best known for his natural law of gases known as Boyles Law. Hooke invented a wide range of things at Christ Church, including a balance spring for watches, but he published few of them. He did publish a tract on capillary attraction in 1661, and it was that treatise the brought him to the attention of the Royal Society for Promoting Natural History, founded just a year earlier. The Royal Society The Royal Society for Promoting Natural History (or Royal Society) was founded in November 1660 as a group of like-minded scholars. It was not associated with a particular university but rather funded under the patronage of the British king Charles II. Members during Hookes day included Boyle, the architect Christopher Wren, and the natural philosophers John Wilkins and Isaac Newton; today, it boasts 1,600 fellows from around the world. In 1662, the Royal Society offered Hooke the initially unpaid curator position, to furnish the society with three or four experiments each week- they promised to pay him as soon as the society had the money. Hooke did eventually get paid for the curatorship, and when he was named a professor of geometry, he gained housing at Gresham college. Hooke remained in those positions for the rest of his life; they offered him the opportunity to research whatever interested him. Observations and Discoveries Hooke was, like many of the members of the Royal Society, wide-reaching in his interests. Fascinated by seafaring and navigation, Hooke invented a depth sounder and water sampler. In September 1663, he began keeping daily weather records, hoping that would lead to reasonable weather predictions. He invented or improved all five basic meteorological instruments (the barometer, thermometer, hydroscope, rain gauge, and wind gauge), and developed and printed a form to record weather data. Some 40 years before Hooke joined the Royal Society, Galileo had invented the microscope (called an occhiolino  at the time, or wink in Italian); as curator, Hooke bought a commercial version and began an extremely wide and varying amount of research with it, looking at plants, molds, sand, and fleas. Among his discoveries were fossil shells in sand (now recognized as foraminifera), spores in mold, and the bloodsucking practices of mosquitoes and lice. Discovery of the Cell Hooke is best known today for his identification of the cellular structure of plants. When he looked at a sliver of cork through his microscope, he noticed some pores or cells in it. Hooke believed the cells had served as containers for the noble juices or fibrous threads of the once-living cork tree. He thought these cells existed only in plants, since he and his scientific contemporaries had observed the structures only in plant material. Nine months of experiments and observations are recorded in his 1665 book Micrographia: or some Physiological Descriptions of Minute Bodies made by Magnifying Glasses with Observations and Inquiries Thereupon, the first book describing observations made through a microscope. It featured many drawings, some of which have been attributed to Christopher Wren, such as that of a detailed flea observed through the microscope. Hooke was the first person to use the word cell to identify microscopic structures when he was describing cork. His other observations and discoveries include: Hookes Law: A  law of elasticity for solid bodies, which described how tension increases and decreases in a spring coilVarious observations on the nature of gravity, as well as heavenly bodies such as comets and planetsThe nature of fossilization, and its implications for biological history Death and Legacy Hooke was a brilliant scientist, a pious Christian, and a difficult and impatient man. What kept him from true success was a lack of interest in mathematics. Many of his ideas inspired and were completed by others in and outside of the Royal Society, such as the Dutch pioneer microbiologist Antoni van Leeuwenhoek (1632–1723), navigator and geographer William Dampier (1652–1715), geologist Niels Stenson (better known as Steno, 1638–1686), and Hookes personal nemesis, Isaac Newton (1642–1727). When the Royal Society published Newtons Principia in 1686, Hooke accused him of plagiarism, a situation so profoundly affecting Newton that he put off publishing Optics until after Hooke was dead. Hooke kept a diary in which he discussed his infirmities, which were many, but although it doesnt have literary merit like Samuel Pepys, it also describes many details of daily life in London after the Great Fire. He died, suffering from scurvy and other unnamed and unknown illnesses, on March 3, 1703. He neither married nor had children. Sources Egerton, Frank N.

Rising Oil Prices and the Scottish business Essay - 7

Rising Oil Prices and the Scottish business - Essay Example Scotland has a very rich history, and it has played a significant role in bringing in enlightenment to the United Kingdom as modern economics was born from the lush green meadows of Scotland. Over the period of time, Scottish businesses have developed their core competencies and reached to a point where they are significantly contributing towards the economy of the country. An analysis of the Scottish business industry would suggest that it is dominated by heavy industry such as shipbuilding, coal mining and steel industries. This stratification of the industry within the Scottish economy suggest that it is heavily reliant on much larger industries involved mostly into Business 2 Business kind of business transactions therefore key economic variables such as rising prices hardly have the impact on them.  A recent history of oil prices suggests that they are on increasing constantly due to various factors. Many analysts believed that rising demand from China and other emerging marke ts such as Brazil, Russia, and India created a strong increase in prices of oil all over the world. Besides, there are different seasonal patterns in production as well as consumption of oil, therefore, the oil prices tend to increase due to these seasonal patterns as well as strong demand from emerging markets. (IMF).  Further, there is a growing increase into the production of alternative energy sources such as ethanol which is selling at high prices, therefore, the oil prices in the market are also going to replicate that process because alternative products are selling at higher prices. Further, the depreciation of the dollar against major currencies such as the Euro is also considered as one of the major factors behind the increase in oil prices.  These rising oil prices, however, are being considered as a good omen for the Scottish business due to different reasons. The following section will discuss whether rising oil prices are good for Scottish businesses.

The Myth of Education and Empowerment Essay Example | Topics and Well Written Essays - 2500 words

The Myth of Education and Empowerment - Essay Example When I look at the aspects of school reform that are happening because of the NCLB legislation, I can understand that there are still several problems that are facing children today and part of it is that there is a systemic change coming that will influence how education is done. Before we move to that information it will be important to state the answer to the question for this essay. We have four very different people who are speaking about education. Each one of these people could be called "radical" in the way education is done today. We have Malcolm X who learned to read using the dictionary and Elijah Mohammed's teachings in the beginning. He read many books after that and become a brilliant scholar in his own right through learning thorough what some teachers call to day, "immersion." He immersed himself in the aspects of education that he wanted to learn. I am not sure that he would be the leader of the group, but I do think that he would agree with Gatto and that he would be for the idea that children could learn better in environments that were not encased in school. Mike Rose understands the plight of the student in public school in a general way. Because he found motivation through one teacher who came to his school, he would understand the unmotivated student and what it takes to get them motivated. He would understand that most of the time, the teacher who reaches out to a child in a different way than most teachers do are the ones that an individual student will work to impress.

National Netball Coach Essay Example for Free

National Netball Coach Essay The national England Netball coach Lesley Dixon does not have to organise matches or transport because the league it self sorts them details out. Mrs Hyams on the other hand has to contact other local teams and sort out matches and tournaments, and means of transport for hers players, which can be stressful and time consuming. When Lesley Dixon has picked her team for a match from her squad she then tells the Netball associate, who then inform the players and provide them with information. When Mrs Hyams has picked the team, she then has to go and find them to tell them. She then has to provide them with fixtures that she has done herself. Lesley Dixon has to has alot netball coaching experience having spent 8 years with Hertfordshire County and later as manager for the England FENA U17 team. This much experience has enabled Lesley to teach netball at a national standard. Where as Mrs Hyams has a level one coaching qualification and no other netball coaching experience. Lesley Dixon represents the netball association she has a lot of pressure because if the national team is not winning matches they will not be bale to qualify for matches against other national teams in a well publicized tournament such as the qualify stages of a manger up coming tournament. This will look bad and the England team will lose support if they do not compete in major matches or tournaments. When Mrs Hyams prepares the netball teams for matches, there is not as much pressure because all netballs teams are entered in to tournaments. So there is no need for qualifying matches. There is also less pressure on Mrs Hyams because there is limited interest in the results of the Barclay netball team, so no one hears if they do well or not. School netball league is competitive but not as competitive as national games. Lesley Dixon gets paid every month for coaching the national England netball team, where as Mrs Hyams who coaches the school team out of school hours, does not get paid for doing so. When one of Lesley Dixon players is injured on court or suffers from injuries during training, she has the medical staff available to treat her players. So she doesnt have to have a medical or first aid qualification. Mrs Hyams has to have a first aid qualification, so when a member of the netball teams is injured, she has to treat them or escort them of court. Ways in which Mrs Hyams can improve her netball coaching ability is to go on level 2 netball coaching course at Bedfordshire Time Venue TBA. This will enable to teach netball at a higher standard and have more knowledge of the game. Mrs Hyams could also go on an beginner umpiring course at Eaton CNS School Easton Road Norwich, so when she umpires her netball teams matches and other netball teams; she can be more competent and confident in her decisions when umpiring. Most of netball team see Mrs Hyams more as a friend than a netball coach. This can sometime lead to a lack of concentration from the players, because we do not see her as an authoritive figure. To improve this Mrs Hyams could be disciplined, which would inevitable cause the team to be more focused. Although Mrs Hyams netball team, who she has coached since year seven have gone on to win the district tournament four years running. This shows Mrs Hyams dedication and hard work as well as the teams. There are not a lot of things Lesley Dixon could do to improve her netball coaching ability. One thing she could do is make netball more publicised so more people start to take notice of netball. This is because to be at a national coaching standard you need to be fully focused and qualified. These qualities are what makes a good coach and cant be faulted. Although Lesley Dixons team have recently failed to pass the test matches against Jamaica. Both types of netball coaches from national standard to school standard have to be knowledgeable about the game in order to lead and coach it to members of the team. The two different coaches have the same principle of coaching which is to teach the game, but have very different responsibilities.

Essay on Metamorphosis of the Family in Kafkas Metamorphosis

Metamorphosis of the Family in Kafka's Metamorphosis      Ã‚   In Franz Kafka's Metamorphosis, the nature of Gregor Samsa's reality changes insignificantly in spite of his drastic physical changes. Gregor's life before the metamorphosis was limited to working and caring for his family. As a traveling salesman, Gregor worked long, hard hours that left little time to experience "life." He reflects on his life acknowledging the "plague of traveling: the anxieties of changing trains, the irregular, inferior meals, the ever changing faces, never to be seen again, people with whom one has no chance to be friendly" (Kafka 13). Gregor, working to pay off his family's debt, has resigned himself to a life full of work.    Kafka himself paralleled this sentiment in a quote taken from his diaries noting that no matter how hard you work "that work still doesn't entitle you to loving concern for people. Instead, you're alone, a total stranger, a mere object of curiosity" (Pawel 167). Gregor submerges himself in work and becomes a stranger to himself and to life. Any type of social contact beyond porters, waitresses or bartenders was non-existent. He had once met a "cashier in a hat shop, whom he had pursued earnestly but too slowly" (Kafka 76).    There was no room in Gregor's life for people other that his family and as a result was condemned to a life without love or caring not to mention basic companionship. He worked diligently to provide for his family and that remained his only goal in life. Gregor's family relied on him to be the "breadwinner" of the family, but gave him nothing in return. The life that he had led until now was one fully of obligations and loneliness; he came home to empty hotel rooms or his apathetic fam... ...g him and longing for his demise. Can anyone be sure that their lives are good and perfect and that their families would understand and accept any change that could arise? The fact is that above and beyond all things a person must consider themselves first, however selfish it might appear. Sense of self will keep you through all the adverse times in life and be a companion to rely on when no one else cares.    Works Cited Eggenschwiler, David.

A Day in the Life of a Teacher Essay

I hear the sound of my alarm clock at 6:30am. Time to get up! I wish it was Saturday, no school! No, I’m not a child, nor a student, but a teacher! You don’t think we enjoy everyday at work, do you? No. That’s rubbish. Let me continue with my story of a day in the life of a teacher.  As I force myself out of bed, a chilling thought comes over me. It’s Wednesday. This means I still have three whole days to get through until the weekend. Better get a move on if I want to make it on time. First, I take a shower. I do this every morning to liven myself up and to prepare for the day ahead of me. Today first up we have a whole school assembly. That’s one reason why I don’t like Wednesdays. The other few reasons I particularly don’t like the day Wednesday is that I have recess yard duty and in the afternoon is the paper parade. I step out of the shower, thinking such thoughts of what has been happening in the last few days and what I have to do today. I get dressed and go out to have breakfast. Mmm, I like breakfast, my last chance in the morning to relax and not think about work, but it eventually creeps into my head anyway. Once I am finished I remember and organize, well I try to remember and organize everything that I will need. Which is a lot. When I arrive at school, about 10 to 8 I park, load up my stuff and walk to the front office. In the staff room I have a social chat to the other teachers, we talk about assembly, make our coffee or tea and get ready to leave. With a mug in one hand, handbag and everything else in the other, we back onto the staff door and out the front office. You can always tell a new teacher, they haven’t got the art of getting out the staff door in the morning perfected yet. I make my way to class avoiding the students and setup and wait in the class until the bell goes at half past 8. Outside the kids are eagerly waiting to be let inside, like a pack of puppies waiting for you to open the door just so they can jump all over you with their muddy paws. What do they eat, must be something like froot-loops. Which would explain not just the sugar rush but a for a few others something else too. As soon as we are all in class, which doesn’t take long, I give announcements and ask the class to take their chairs to assembly. When we arrive I round up my class, and once everyone is seated its time to go home. I wish! Though it is about 20minutes later. At the beginning of every assembly we stand and sing the national anthem. Which doesn’t sound like an anthem at all. Instead of sounding like we are proud and free, it’s sung in a droning tone. When we sit down I shush all the chatters and the assembly begins. As a teacher it’s our duty to listen to what is happening around the school while also keeping a small eye, quite like a hawks, on the class. We all usually sit back, act interested and see all the small things that go on. Like the two kids who like each other keep pretending to ‘look around the room’ but are really trying to catch a smile. Then there are the bad kids, who are trying to make peashooters and all the usual blabbermouths who can’t even wait until recess to talk. Since this assembly is so boring and I am bored I will go over, grab the troublemakers and sit them next to me. The rest of assembly goes on like this and is pretty much a huge waste of time and effort. At the end we ask our class to move off. We head off and back to class, when we are all finally in class I give out a quick spelling test. It’s really a time waster and a fill in until recess. When the bell goes I think of how nice it will be to relax in the staff room. Then a student comes up and mentions something about handing a form in today, Wednesday. It hits me then that I have to do.. yard duty. Out I go, trying to avoid the smaller kids who seem to want to follow me around, some even cling my leg . At the end of recess I have a 5minute break in the staff room. Some break! I quickly get a drink and then hear the bell, time to go to class. Back in class its maths time. Everyone lines up, and then I tell him or her to go inside. I ask my class to sit on the mat after about 10minutes and 2 disagreements everyone is seated. I have release time so I wait for the principal to come, because he is taking over my class. Release time, although it is called ‘release’ is a time where we just do things that aren’t done yet. Like marking work, writing a program, or putting together all the things we need to. I have reports to write, since it is the end of the term. There are a few simple things to do when writing reports to make the process as simple, easy and stress free as possible. First sort out the kids. There’s the good, the bad and the in between. The in between are really good kids, which you personally don’t like and torture for the fun of it. Then write a set paragraph for each of the groups, with 3-5 different wordings, which really mean the same thing. Once children are categorized the fun begins. Comment after comment is inserted into the report, but when I feel that a student stands out, I add my own personal touch. Two words -Be creative. After report writing I have to mark work, this is a very slow and boring process. After a few minutes a fellow teacher of mine comes into the computer room to tell me that the Principal has left for a meeting and I will have to go back and take my class, even though there is only 10minutes until the lunch bell rings.
