Robert Hooke :: biographies bio

Robert Hooke was an Englishman, born in Freshwater, Isle of Wight on July 18, 1635. He died in London on March 3, 1703. During his life he contributed a great deal to the world of science, contrary to what was expected of him at an early age. As a child, Robert Hooke was constantly in poor health. It was never expected that he would live past his childhood. He had frequent headaches which made studying for school very difficult. His parents decided to quit pursuing an education for their son, and Hooke was left to learn on his own accord. He became fascinated by mechanical objects such as toys and clocks. He also developed a talent for drawing. Hooke did survive to see adulthood, and old age. In his 68 years he held many positions in different fields. * Apprentice to Peter Lely, a portrait painter of the time * Professor of geometry at Gresham College in London * Assistant to Robert Boyle * London City Surveyor * Curator of experiments for the Royal Society of London * Lecturer on mechanics * Secretary of the Royal Society of London Robert Hooke invented many instruments for variable purposes. The following is a limited list of his many inventions. * modern air pump * wheel, double, & marine barometers * anchor escapement of clocks * spring control of the balance wheel in watches * arithmetic machine * 1st Gregorian telescope * compound microscope * reflecting telescope * diving engine * spiral gear * universal (Hooke's) joint * iris diaphragm * lens grinding machine * conical pendulum * springy saddle * horizontal sail for windmills * applied telescopic sights to surveying instruments * air gun Robert Hooke's first publication was in 1661, on the subject of capillary action.

Short Story Essay

The characters In the science fiction genre are too small minded to see the big picture. These characters are unable to evaluate the consequences of their actions. The characters are also resistant to the warnings of others. As a result, their ignorance may not only have jeopardized their own life and freedom, but may also have Jeopardized the lives and freedom of others. Characters in the science fiction genre are unable to evaluate the consequences of their actions and as a result jeopardize their own lives and freedom or the lives and freedom of others.To begin, in the short story â€Å"Men are Different† by Alan Bloch, the Robot is unable to see that treating the man as he would a fellow robot could result in the mans death, and ultimately the end of mankind. In the story the Robot decides that the man needs to be fixed and attempts to see what Is wrong with him: â€Å"†¦ His thermostat circuits were shot†¦ I turned him off without any trouble† (Bloch 1). The robot archeologist Is here studying the last man In the system. When the man begins complaining of the heat the Robot assumes he can fix him by opening him up as he loud do to another Robot.This shows that the Robot is unable to evaluate the consequences that may occur if he tries to fix this man. He is unable to see that he does not have the knowledge to fix a human and ultimately ends up killing the man, and ending mankind as a whole. Next, in the story â€Å"Random Sample† by T. P Caravan, the little girl could not see that by being mean and aggressive towards the aliens she could be putting her life, and the lives of others in Jeopardy. The little girl is telling the psychologist about her encounter with the aliens when she explains, â€Å"Anyway, hey paid a lot of attention to him, so I went over and punched him a couple of times.I'm afraid we broke up the insides of their spaceship a little† (Caravan 2). Here, the little girl Is telling the doctor about how s he Interacted with the aliens. She starts explaining what happened and It Is shown that she was very mean and aggressive towards them. By misbehaving and hurting the aliens and their spaceship, it proves that the little girl was unable to evaluate the consequences that would follow her actions. Ultimately, by acting this way towards the aliens she gave them a bad impression of humans which made them return to earth and kill off the human race. Lastly, in the story â€Å"Before Eden† by Arthur C.Clark, the scientists were unable to think about the consequences to Venus and its life forms if they buried their waste on the planet. After Hutchins and Garfield burry their waste and leave, the carpet plant comes back and discovers the garbage they left behind: â€Å"As the carpet crawled back to the lake, it carried contagion to all Its world. Even as the Morning Star set Its course for her distant home, Venus was dying† (Clark 6). When Hutchins and Garfield bury their garba ge on Venus, they do not think about how It could affect the planet. The carpet ends up coming back, finding the garbage and then eating It.The concentrated food, chemicals and nicotine from cigarette butts end up infecting the their garbage on the planet, they ultimately killed off all of the life on Venus. In conclusion, these characters in the science fiction genre were unable to evaluate the consequences of their actions and in all cases either put their own lives and freedom r the lives and freedom of others in Jeopardy. The characters in the non-fiction genre are resistant to the warnings of others and as a result, put their own lives and freedom or the lives and freedom of others in harms way.To start, in the story â€Å"The Weapon† by Frederick Brown, the doctor does not listen to the warning of Mr†¦ Maenad about his creation of the weapon. When Mr†¦ Maenad comes to Dry. Graham's house he expresses his concern about what Dry. Graham is creating: â€Å"Dry. Graham, you are the man who's scientific work is more likely than that of NY other man to end the human race's chance for survival† (Brown 1). As soon as Mr†¦ Maenad enters the doctors home, he warns him of how dangerous the weapon he is creating will be to mankind. Dry. Graham is resistant to his warning and claims that he is only advancing science.Ultimately, Dry. Graham ignores the warning and creates a weapon that could destroy mankind. It is only when Mr†¦ Maenad gives a gun to his mentally ill son, that he realizes how destructive the weapon really is if put in the wrong hands. Next, in the story â€Å"A Sound of Thunder† by Ray Bradbury, the hereafter Sickles does not listen to Travis' warning about leaving the Path and how it could change the future. When Sickles asks why they cannot leave the Path, Travis explains, â€Å"Step on one mouse and you leave your print, like a Grand Canyon, across Eternity.Queen Elizabeth might never be born†¦ There m ight never be a United States at all. So be careful. Stay on the Path. Never step off† (Bradbury 7). Here, Travis is explaining to Sickles why it is important to never leave the Path. While Travis is explaining this, Sickles questions him and does not believe that what Travis is saying sakes any sense. Sickles ignores the warning and later on in the story when he is running back to the time machine, he steps off the Path and changes the future.Ultimately, he puts peoples lives and freedom in danger by ignoring the warning and changing the future. Lastly, in the story â€Å"The Murderer† by Ray Bradbury, Mr†¦ Brock does not listen to the warning the psychiatrist gives him about damaging technology and as a result Jeopardizes his own freedom. When the psychiatrist is speaking to Mr†¦ Brock, he asks him if he's aware that the technology he is damaging is not his and says, Mimi don't want any further help from the Office of Mental Health? You're ready to take the consequences? (Bradbury 4). The psychiatrist is here explaining that because the technology he destroys is not his, if he does not take help from the Office of Mental Health he will be punished. Mr†¦ Brock ignores the warning and says it is only the beginning. By ignoring the warning, Mr†¦ Brock puts his own freedom in jeopardy and therefore has to remain in prison. The characters in the non fiction genre were too resistant to the warnings of others, and as a result put their own lives ND freedom or the lives and freedom of others in Jeopardy.In the science fiction genre, characters put their lives and freedom or the lives and freedom of others in Jeopardy. Characters in this genre cannot evaluate the consequences of their actions. The characters are also resistant to the warnings of small minded and blinded by what they want. The characters go by their own agenda rather than considering the greater good. They do not look at the bigger picture which results in their own de ath and loss of freedom, or the death and loss of freedom of others.

The Power of Knowledge

The Power of Knowledge Our present day cabinet of curiosities (the â€Å"Cabinet†) is akin to early modern representations, which contained a vast range of objects representing the power of divine creation, in that the Cabinet represents, through its display of five objects, the power of human knowledge. Each of these objects helps mankind acquire and/or use knowledge.The order of objects displayed has been designed to reflect the evolution and utilisation of knowledge: an illustration of the DNA spiral helix (the building blocks of life); seed samples (the growth and development of organisms); the electron icroscope (allowing detailed examination of objects); the tablet-style computer (the dissemination and democratisation of knowledge); and the moon rock (exploration of space). DNA Spiral Helix The deoxyribonucleic acid (DNA) helix is the only object in the Cabinet which is a representation.Whilst DNA exists in every cell it would need the Electron Microscope to render DNA v isible. Two strands are shown twisted into a helix with rods between the strands. How does this represent DNA? Phillip Cohen (2006) describes the helix thus: Each strand spells out the genetic code as a chain of four chemical letters alled bases: adenine (A), thymine (T), cytosine (C) and guanine (G). A,C,G and T sit on the rods between the two strands which are made from a sugar molecule and a phosphate molecule (Genetics Home Reference, 2013).The discovery of DNA and the evolving knowledge of it, has proved immensely powerful because of what it enables us to do, for example: to detect a criminal's guilt from a single hair beyond reasonable doubt; detect family connections by comparing DNA from two or more people, dead or alive; (hence the certainty that it was Richard Ill's remains found in Leicester); and to give the power to cure or eliminate previously incurable diseases, through the mapping of the human genome.Seed Samples Seed samples appear on the shelves at the seed bank of The International Maize and Wheat Improvement Centre, labelled in see-through closed plastic containers. The first seed bank was established by N. Vavilov in 1926 outside St. Petersburg, for scientific research and cross-breeding purposes (BBC, 2013). Since then the world has changed dramatically, resulting in an increased consumption of natural resources. Seed banks around the world have assumed a new and very important ole in the preservation of rare and dying species of all kinds of plant forms.Today the Millennium Seed Bank in Kew Royal Botanic Gardens is working on the ‘Noah's ark project and has acquired ten percent of the world's plant species threatened by climate change and the expansion of human habitats (Kew, nd). Seed samples preserved by seed banks provide not Just the opportunity for detailed study but also the power, opportunity and possibility for future generations to preserve most of the plant forms in the world (as we know it now) and to regenerate species to help feed the growing world population. An Electron Microscope This electron microscope is linked to three computer screens, showing typhoid bacteria in pink.Invented in 1 by German natural philosophers Max Knoll and Ernst Ruska, the electron microscope, though cumbersome and expensive is â€Å"capable of high magnification and greater resolving power than a light microscope† Oohn Innes Centre, 2013). Its capability to magnify finer details by two million times, revolutionised the studies of the behaviour and treatment of light resistant bacteria (such as typhoid bacteria) and viruses and enables detailed forensic analysis to take place. This object symbolises man's quest not only to understand his natural environment, but his ambition to control and manage it.The micrographs are artefacts in their own right; they can be displayed on their own as scientific evidence. The electron microscope can be displayed alone in a science museum, as a demonstration model for public use or in the Cabinet with the other four items chosen, to show the prominence and ever-increasing possibilities of technology and science and to illustrate man's evolving knowledge. A Tablet Computer Tablet-style computers combine several electronic components, such as a computer, amera and hand-held gaming device, into one convenient portable package (Martin, 2013) which is affordable for many consumers.The invention of the personal computer allowed individuals to access academic libraries and newspapers/ magazines via the internet (Slaughter, 2010) and (eventually) to communicate with other users, subject to a web connection. A tablet computer allows access to a wealth of information. A search engine acts as a filter to any subject; this enables appropriate content to be accessed. The rising popularity of internet-enabled phones, results in thousands more opportunities to access and create data being pened up. This technology enables knowledge to be shared and democratised – no longer resting with a narrow elite (Slaughter, 2010).The tablet computer incorporates a camera to allow for the quick transfer of photographs and videos around the world. The camera can challenge and record human behaviours: this ability to provide a contemporaneous record of human behaviour has resulted in the power of Governments to dictate the historical record of events being publicly challenged. Early computers also helped plot the course to the moon of the Apollo 11 flights in 1969. (Taylor, 2013). A Piece of Rock from the Moon Moon rocks are of various shapes and sizes and â€Å"range in age from about 3. billion years up to about 4. 5 billion years old† (Museumwales, 2009). A wealth of previously unknown knowledge has been gained from studying these rocks, they have â€Å"been of great value in advancing our understanding of the Moon and the history of our solar system† (Astro. washington, 2009). Scientists believe that earth rocks and moon rocks were once e ither part of the same body or were originally combined before they were formed (Natural history museum, nd). On religious grounds, this could challenge raditional views on God's formation of the earth.Moon rocks can be exhibited on their own as artworks – as natural art that reflect the universe in a microcosmic form in accordance with the Chinese tradition of the Philosopher Stones (BBC News, 2012). Moon rocks are priceless due to their scarcity, given the high cost of returning to the Moon to obtain more. In conclusion, the Cabinet symbolises the startling possibilities of human potential and the evolution of knowledge. The discovery of DNA and the creation of the Electron Microscope enabled, in their turn, turtner discoveries and developments to ake place. Conversely, the collection of seed samples allows for the preservation of what currently exists. 0 The tablet computer encapsulates the democratisation of knowledge, through ever-increasing access to data. 0 The moon ro cks represent the ambition to move beyond the world and the infinite possibilities of exploring and understanding our universe. 0The Cabinet is designed to inspire awe in the observer through the display of symbols of the technological and scientific progress that has led to a better understanding of our world and beyond.

Local Color In Huck Finn Essay

Huckleberry Finn, a tale about a boy and his struggles with the society in which he lives, is written by Samuel L. Clemens. In the story, Huck manages to escape from the custody of Widow Douglas and travels down the river to a nearby island where he encounters Miss Watson’s runaway slave, Jim. Together, they float down the Mississippi River, to find a new life, where they can live freely and easily. The Adventures of Huckleberry Finn is perhaps the finest example of â€Å"local color†, an emphasis which is laid on the surrounding settings. Throughout the novel, Clemens accents â€Å"local color† by illustrating the natural scenery, the way of thinking, and the distinct practices and folklore encompassing the area. The novel’s plot revolves around the Mississippi River. The river breaks all the barriers of the time period, between black and white, young and old, slave and free. With their many journeys on land, they invariably return at the raft. While stopped in a near by village, Huck and Jim manage to escape the king and the duke, seeking refuge on raft. â€Å"It was the raft, and mighty glad was we to get aboard of it again†(Clemens 1309). Later on in the novel, at the Phelps Farm plantation, Tom and Huck learn that Jim is held captive in a hut just beyond Aunt Sally’s house. They devise a scheme to get him out, involving digging a tunnel, sawing off a leg of a bed which Jim was chained to, using a rope ladder, and having Jim flee from a makeshift window. The plan runs smoothly, all three exiting through the man made hole, until Tom gets caught on a piece of wood, which creates a clamorous noise. At that moment, they began their retreat in a hurry. Fifteen men, equipped with rifles and dogs, begin their hunt for the three outlaws: â€Å"Then we struck out, easy and comfortable, for the island where my raft was; and we could hear them yelling and barking at each other†Ã‚ ¦Ã¢â‚¬ (Clemens 1442). They manage to, once again, get away seeking protection on the raft. The raft shielded both Huck and Jim from nearly every obstacle, yet slavery was still present no matter where they were. During the time this novel was set, just prior to the 1860’s, slavery prevailed all across the United States, especially in the South. Slaves were thought of as property for the white man to own, thus making them inferior. It was not until the Civil War where the slavery issue was addressed and eventually resolved. Throughout  the story, Huck and Jim travel down the Mississippi in search of freedom. Jim escapes from the possession of Miss Watson, fearing she was going to sell him down the river and thus separate him from his family. At one of their stops, at the Phelps farm, Huck hears a story from Tom’s Aunt Sally about an explosion on a boat: â€Å"It warn’t the grounding † that didn’t keep us back but a little. We blowed out a cylinder-head. Good Gracious! Anybody hurt? No’m. Killed a nigger. Well, it’s lucky; b ecause sometimes people do get hurt†(Clemens 1409). Ultimately, at the culmination of the novel, Miss Watson grants Jim his freedom, as stated in her will. Much of the population of this time based most of their practices and rituals on either the Bible or folklore. Jim, Miss Watson’s slave, had a hairball, taken from the fourth stomach of an ox. He believed this hairball was a prophecy, which truly spoke to him. In another episode, while Huck is stranded on Jackson’s Island, he hears loud explosions in the distance: â€Å"You see, they was firing cannon over the water, trying to make my carcass come to the top†(Clemens 1287). It was common knowledge of the time that when a dead body is in a river, the vibrations from the cannon ball will enable it to rise and float. Furthermore, residents believed that when quicksilver was put into loaves of bread, it would float to the dead carcass. The Adventures of Huckleberry Finn has numerous instances in which â€Å"local color† is present. Throughout the novel, heavy focus is laid upon the Mississippi River, and the villages close by. Common men and women used superstition and folklore to explain and solve life’s natural phenomena. Along with this is the portrayal of the brutal aspects, both physical and psychological, of slavery. At the conclusion of the novel, all hurdles are overcome, and Jim and Huck become free. Most of the population of this time was narrow-minded, being on the river, away from society, allowed Huck and Jim to overcome these bounds.
