Biography of Physicist Ernest Rutherford

Ernest Rutherford was the first man to split an atom, transmuting one element into another. He performed experiments on radioactivity and is widely regarded as the Father of Nuclear Physics or Father of the Nuclear Age. Here is a brief biography of this important scientist: Born: August 30, 1871, Spring Grove, New Zealand Died: October 19, 1937, Cambridge, Cambridgeshire, England Ernest Rutherford Claims To Fame He discovered alpha and beta particles.He coined the terms alpha, beta, and gamma rays.Identified alpha particles as helium nuclei.He demonstrated radioactivity was the spontaneous disintegration of atoms.In 1903, Rutherford and Frederick Soddy  formulated the laws of radioactive decay  and described the disintegration theory of atoms.Rutherford is credited with discovering the radioactive gaseous element radon, while at McGill University in Montreal.Rutherford and Bertram Borden Boltwood (Yale University) proposed a decay series to categorize elements.In 1919, he became the first person to  artificially induce a nuclear reaction in a stable element.In 1920, he hypothesized the existence of the neutron.Lord Rutherford pioneered the orbital theory of the atom with his famous gold foil experiment, through which he discovered Rutherford scattering off the nucleus. This experiment was fundamental to the development of modern chemistry and physics, as it helped describe the nature o f the atomic nucleus. Rutherfords gold foil experiment, also known as the  Geiger–Marsden experiments, was not a single experiment, but a set of experiments conducted by Hans Geiger and Ernest Marsden under Rutherfords supervision, between 1908 and 1913. By measuring how a beam of alpha particles was deflected when striking a thin sheet of gold foil, the scientists determined (a) the nucleus had a positive charge and (b) most of an atoms mass was in the nucleus. This is the Rutherford model of the atom.He is sometimes called the Father of Nuclear Physics. Notable Honors and Awards Nobel Prize in Chemistry (1908)  for his investigations into the disintegration of the elements, and the chemistry of radioactive substances - Affiliated with Victoria University, Manchester, United Kingdom Knighted (1914)Ennobled (1931)President of the Institute of Physics (1931)  After the war, Rutherford succeeded his mentor J. J. Thomson in the Cavendish Professorship at Cambridge  Element 104, rutherfordium, is named in his honorReceived several honorary fellowships and degreesBuried in Westminster Abbey Interesting Rutherford Facts Rutherford was the 4th of 12 children. He was the son of farmer James Rutherford and his wife, Martha. His parents were originally from Hornchurch, Essex, England, but they emigrated to New Zealand to raise flax and start a family.When Rutherfords birth was registered, his name was mistakenly spelled Earnest.After completing his degree at the university in New Zealand, his job was teaching rebellious children.He left teaching because he was awarded a scholarship to study at Cambridge University in England.He became  J. J. Thomsons first graduate student at the Cavendish Laboratory.Rutherfords initial experiments dealt with the transmission of radio waves.Rutherford and Thomson conducted electricity through gases and analyzed the results.He entered the new field of radioactivity research, just discovered by  Becquerel and Pierre and Marie Curie.Rutherford worked with many interesting scientists of the time, including Frederick Soddy, Hans Geiger, Neils Bohr,  H. G. J. Moseley, J ames Chadwick, and of course J. J. Thomson. Under Rutherfords supervision, James Chadwick discovered the neutron in 1932.His work during World War I focused on submarine detection and antisubmarine research.Rutherford was called Crocodile by his colleagues. The name referenced the scientists relentless forward thinking.Ernest Rutherford said he hoped scientists would not learn how to split the atom until  Ã¢â‚¬Å"man was living at peace with his neighbors.† As it turned out, fission was discovered only two years after Rutherfords death and was applied to make nuclear weapons.Rutherfords discoveries were the basis for the design and construction of the  largest, most energetic particle accelerator in the world -- the Large Hadron Collider or LHC.Rutherford was the first Canandian and Oceanian Nobel laureate.

Digital Technologies are Powerful Tools for Education

Digital technologies, radio and TV can be powerful tools for education. Dr. Samuel Chindaro said, â€Å"They can inspire, engage and provide young people with important skills.† Education and human capital are fundamental to the socio-economic development of Zimbabwe. Utilizing information, media and communication technology (ICT) will help Zimbabwe battle their educational problems. ICT includes radio, television, and digital technologies such as computers and the Internet, each are powerful instruments for educational change and reform. â€Å"These technologies can help expand access to education, strengthen the relevance of education to the increasingly digital world, and raise educational quality by, among others, helping make teaching and learning into an engaging, active process connected to real life,† (Chindaro 2013). Furthermore technology can be used to replace the insufficiencies in the education system. For example, boosting administrative and teaching adept ness, assuaging under-resourcing and supporting teachers who lack supplies. The utilization of media and communication can also be used to create a public awareness campaign for Zimbabwe’s education system whose goal will be to reinforce the importance of education. This can be done through music festivals and other forms of public art, advertisements and media coverage. â€Å"We are at an exciting time of enhanced public awareness and interest in human rights.

Role of Women in Canterbury Tales Essay Example For Students

Role of Women in Canterbury Tales Essay The Canterbury Tales by Geoffrey Chaucer serves as a moral manual for the 1300s and years after. Through the faults of both men and woman, he shows in each persons story what is right and wrong and how one should live. Under the surface, however, lies a jaded look and woman and how they cause for the downfall of men. The Knights Tale is one of chivalry and upstanding moral behavior. However, beneath the surface lies the theme of the evil nature of women. Emily plays the part of the beautiful woman who captivates the hearts of two unsuspecting men. Those two men are cousins Arcite and Palamon, both knights who duel for Emilys hand in marriage. The two start out as the best of friends and then roommates in a jail cell that is to be shared for eternity. But with one look at Emily, the two start bickering instinctively and almost come to blows over something they will never be able to have, or so it seems. Chaucers knack for irony revels itself as Arcite is released from his life sentence but disallowed from ever coming back to Athens. He would be killed ever caught within the city again by King Theseus. Because Arcite is doomed to never again see Emily, his broken heart causes him sickness as hes weakened by love. It is only after he comes up with the plan of returning to Athens under an assumed nam e that he starts to get better. Meanwhile, Palamon remains back in captivity, rendered helpless due to his lifelong punishment in prison. He knows that he will never be able to talk to Emily and certainly not marry her because of his plight. All he can do is watch her froma distance and admire her beauty. Arcite believes that this is a better punishment than his, though, as he says:O dere cosin Palamon, quod he,Thyn is the victorie of this aventureFul blisfully in prison maistow dure;In prison? Certes nay, but in paradys!Wel hath fortuen y-turned thee the dys,That hast the sighte of hir, and I thadsence. But I, that am exyled and bareyneOf alle grace, and in so greet despeir,That ther nis erthe, water, fyr, ne eir,Ne creature, that of hem maked is,That may me helpe or doon confort in this:Wel oughte I sterve in wanhope and distresse;Farwel my lyf, my lust, and my gladnesse! (58 and 60)Emily has caused him such distress that he cries all the time and contemplates killing himself so he wont have to feel this every day pain that appears to have no end. All of this because of a woman. Emily is a sweet, innocent woman of her times. In a strange twist for a woman of The Canterbury Tales, she is perfectly happy alone and doesnt ever want to be married. Yet, Palamon and Arcite duel twice for Emilys love and Arcite ends up losing his life all because of her. Palamon, winning her by default, serves Emily faithfully for several years before she agrees to marry him, still notloving him, though. No one wins in The Knights Tale, but it is the two men who fight over the woman who lose the most. The Nuns Priests Tale is perhaps the best representation of mens downfall due to the influence of women. The story revolves around a rooster, Chauntercleer, the most beautiful cock in all of England with the sweetest voice an any ear has heard. He has seven wives but his favorite was Pertelote, an elegant hen in her own right. It is this woman, this female, that causes Chauntercleer greattrouble. One night Chauntercleer wakes suddenly from a bad dream. Seemingly seeking comfort in her, he tells Pertelot about the dream which involves a wild, rampant dog with beady eyes coming after Chauntercleer.But instead of consoling her husband, she challenges his manhood and says that no man hers should be scared of a dream. This causes Chauntercleer to go off on a tangent about the many, many times in history dreams have predicted the future and hownon-believers suffered the consciences of not taking the proper precautions. After he done, however, he says that Pertelot is probably right and goe s off about his day not giving it another thought. This causes the narrator to take an aside from thestory to tell us his own opinion on women but says that it is the belief of many men and not his own in an attempt to perhaps cover himself. In this he says:Wommennes counseils been ful ofte colde;Wommannes counseil broughte us first to wo,And made Adam fro paradys to go,Theras he was ful mery, and wel at ese. .uff79293c1c7cc202d568bb8084d1d962 , .uff79293c1c7cc202d568bb8084d1d962 .postImageUrl , .uff79293c1c7cc202d568bb8084d1d962 .centered-text-area { min-height: 80px; position: relative; } .uff79293c1c7cc202d568bb8084d1d962 , .uff79293c1c7cc202d568bb8084d1d962:hover , .uff79293c1c7cc202d568bb8084d1d962:visited , .uff79293c1c7cc202d568bb8084d1d962:active { border:0!important; } .uff79293c1c7cc202d568bb8084d1d962 .clearfix:after { content: ""; display: table; clear: both; } .uff79293c1c7cc202d568bb8084d1d962 { 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; } .uff79293c1c7cc202d568bb8084d1d962:active , .uff79293c1c7cc202d568bb8084d1d962:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uff79293c1c7cc202d568bb8084d1d962 .centered-text-area { width: 100%; position: relative ; } .uff79293c1c7cc202d568bb8084d1d962 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uff79293c1c7cc202d568bb8084d1d962 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uff79293c1c7cc202d568bb8084d1d962 .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; } .uff79293c1c7cc202d568bb8084d1d962:hover .ctaButton { background-color: #34495E!important; } .uff79293c1c7cc202d568bb8084d1d962 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uff79293c1c7cc202d568bb8084d1d962 .uff79293c1c7cc202d568bb8084d1d962-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uff79293c1c7cc202d568bb8084d1d962:after { content: ""; display: block; clear: both; } READ: Not a chance EssayBut for I noot to whom it mighte displeseIf I counseil of wommen wolde blame,Passe over, for I seyde it in my game.

(404)Chauntecleer later is indeed attacked by a wolf and carried away to the woods to his certain doom before slipping away, proving the point that women are the downfall of men. If he had listened to himself and his dreams instead of Pertelote, Chauntecleer would have been more cautious of not of had the near-death encounter he did.Finally, the prologue to the Wife Of Baths Tale shows the reader another type of woman of the time, this time in the effect of the story teller. The Wife Of Bath is a tough woman with a mind of her own and shes not afraid to speak it. She intimidates men and woman alike due to the strength she possesses. But instead of showing this as a good characteristic, Chaucer makes her toothless andugly. She has also had five different husbands and countless affairs, thus breaking innocent mens hearts. In one part of the prologue, the Wife Of Bath speaks of marriage and women from a mans point of view:Thou lykenest wommanes love to helle,To bareyne lond, ther water may not dwelle. Thou lyknest is also to wilde fyr:The more it brenneth, the more it hath desyrTo consume every thing that brent wol be. Thous seyst right as wormes shende a tree,Right so a wyf destroyeth hir housebonde;This knowe they that been to wyves bonde. (198)The Wife Of Bath brings up many a valid point throughout the prologue but Chaucer voids her opinion because of her social class and looks, when in truth she is very wise. It is as if her intelligence is overshadowed by the fact that has had five husbands and considered something of a whore.It is not only in three narrations that women are thought of as having an evil-like quality, that they always tempt and take from men, but in almost every one of the stories. They are depicted of untrustworthy, selfish and very vain throughout the collection of tales. Chaucer obviously has very opinionated views of the marriage and the opposite sex and expresses it very strongly in TheCanterbury Tales.

Me And Roommate Essays - Book Of Genesis, Cheshvan, Noach, Noah

Me And Roommate Dear New Roommate, It is hard for me to describe myself to you in simple words. I can tell you that I am an energetic and compassionate person, but what does that tell you? I would rather show you who I am by telling you what my hopes and dreams are, what the driving force in my life is, and this will lead you to understand who I really am, as a person. Only when you get to know these things about me is when you really start to understand what type of person I really am, not just the fact that I am a blond twenty-two-year-old that wants to be a teacher. To make the difference in the lives of children is such an important goal to me. I remember when I was in elementary school, I adored my teachers, they were the world to me. I always felt special and successful because of the love, support and knowledge that my elementary teachers gave to me. I long to give back to children what I was so lucky to receive from my teachers as a child. This has been a major factor in my strive to become an elementary school teacher. By giving children the love, support and education they need, they have a greater chance of living a solid, stable and productive life. What is most important to remember is that children are our future. My journey to become a teacher started as early as Junior High. I started baby-sitting the children in my neighborhood when I was in seventh grade. I loved spending time with children, and by the time I was in high-school, I had many permanent baby-sitting jobs throughout Ojai, the small town we live in. Even when I moved away to San Luis Obispo, to go to college, I never gave up caring for children. I quickly found a nanny job watching two young girls while I was in San Luis Obispo, which I kept for two years. Although these were only small side jobs, they meant much more. I spent hours outside of work going to school plays, soccer games, and dance recitals of the various children that I baby-sat. The real motivation to become a teacher came to me when I started working at a Christian preschool and daycare when I moved back to Ojai. I have worked at Noahs Ark as a licensed daycare teacher for the past two years. Some of my responsibilities included ensuring the safety of the children, supervising them at play, homework club, creating the curriculum and daily activities for the children, and equally important, loving and nurturing the children while they are in my care. Noahs Ark has provided me with the opportunity to work with a diverse population of children. I have worked with low-income families on scholarships, physically disabled children, and students with emotional problems. Children from all ethnic backgrounds attend Noahs Ark and each one has brought their unique culture into the program. This has been a great learning experience for me. It has helped me gain patience, understanding and leadership abilities as well as learning about new cultures. I have a high inner drive to begin my teaching career. I am very energetic and motivated in all that I do. Children are very special to me and I love working with children from all cultures and backgrounds. I feel that by pushing the idea of having a diverse class, that the students themselves can potentially create a unique and enriching learning experience for themselves. I feel that through each other, the children can learn about history, traditions, and the cultures of other people. This, in turn, will ideally create a more tolerant, loving classroom situation, and hopefully this tolerance will go much further than the classroom doors. I think that California Lutheran University is the perfect school to help me reach the goals that I have set for myself. I want to be in a school that will give me a broad-based education. I feel that the people at Cal Lutheran, both students and faculty are deeply aware of todays most important issues. I also love the fact that, through Cal
