The New Album Of Taylor Swift "Speak Now"








"Speak Now" was solely written by Swift as were all the tracks for the album.The song was inspired by one of Swift's dear friends and her story with her high school sweetheart. The couple had parted their separate ways after high school — with the idea that they would get back together. Swift acknowledged that she even thought it was inevitable for them to reunite. One day, Swift's friend comes to inform Swift that her high school sweetheart would presently wed. Her friend's ex-boyfriend had met a new female, who Swift believed to be of a negative persona. She said, "He had met this girl who's just this horrible, mean person who made him completely stop talking to all of his friends, cut off his family. She had him so completely isolated."While engaging in conversation with her friend, Swift asked her friend if she attempted to "speak now." Perplexed, her friend asked for an explanation, to which answered, "You know, storm the church. 'Speak now or forever hold your peace.' I'll go with you. I'll play guitar. It'd be great."Swift's friend found the idea to be humorous, laughing at the idea.

After speaking with her friend, Swift became deeply fixated on the idea of how tragic it would be for the person one loved to wed someone else. That night, Swift experienced a dream where one of her own ex-boyfriends married another girl. To her, this signaled that she had to compose a song about interrupting a wedding. In retrospection, she concluded, "For me, I like to think of it as good versus evil. And this girl is just completely — just the evil one."Swift entitled the album after "Speak Now" because it fit the album's concept, each song being a different confession to a person, well."It's called Speak Now, and that pertains to the album as a concept and as an entire theme of the record more than I can even tell you", she said.A 30-second clip of the song was previewed on Comcast's Xfinitytv.com on October 4, 2010."Speak Now" was released as a
promotional single from Speak Now on October 5, 2010 as part of Countdown to Speak Now, an exclusive campaign launched by the iTunes store


Taylor Swift celebrated the arrival of speak now with a fan-filled album-release party at the Metropolitan Pavilion in Manhattan on Monday (October 25). The party not only included an amped-up performance by Swift, but also fans from around the world, who dined on sushi, mac and cheese and lobster.
Swift hung out with partygoers during her meet-and-greet and seemed genuinely excited by the chance to catch up with fans on the day of her release. She hugged and took pictures with every one of them. Wearing a yellow satin dress with maroon patent heels, she not only met with her fans, but also took questions from them during the nearly hour-long live stream on MTV.com, VH1.com and CMT.com.
Fans asked about everything: What inspired the album? "For me, Speak Now was inspired by the last two years of my life ... that's why I write songs," she said before joking about whether there was anything she wouldn't write about. "Well, I thought so before this album," she laughed. "There's a little more speculation now than when I was 12."
Swift sang three tracks from the new album, displaying sass and confidence during the performance of the album's title track as fans sang along to every word. She then curtsied as her fans cheered her.
"This album took two years to write, two years to make ... and these are songs about stories and lessons and things that I've learned — the right way, the wrong and, in the case of this song, it's about learning a lesson a little too late," she said before kicking into one of the most buzzed-about tracks on the album, "Back to December," which is reportedly an apology to Taylor Lautner.
Saying she went through "obsessive editing" while making the album, she shared, "I ended up writing this song — actually every song — alone, and that happened by circumstance. ... I've never written an entire album on my own before, so songwriting is my favorite thing. It's all what makes life make more sense to me."
Playing a bedazzled acoustic guitar, Swift then went into "Mine," the first single from Speak Now. Swift took in fans' cheers as she wrapped up the song.
Before the night was over, Swift announced the final winner, Savannah, who would be joining her as she flew to L.A. from NYC on Wednesday evening. "I've had such an amazing experience," Swift said to close out the night.

How your opinion about her new album??

Ursula K. Le Guin







American writer of science fiction and fantasy, poet and critical essays. Le Guin has examined large ethical, moral, and social issues in her work and her fame has extended beyond the genre boundaries. Her thought-provoking novels include The Left Hand of Darkness (1969), which won both the Hugo and Nebula Awards, as did The Dispossessed (1974). The celebrated Earthsea books, written for young adults, have been compared to C.S Lewis's Narnia chronicles and Tokien's The Lord of the Rings.
Ursula K. Le Guin was born in Berkeley, California, the daughter of Dr Alfred and Theodora Kroeber Quinn. Le Guin's mother was a psychologist and writer of children's stories. Her father was the head of UC-Berkeley's Department of Anthropology, who published work on Native Americans. Le Guin grew up both in an academic atmosphere, but her summers she spent in a ranch in northern California. The family had also an East Coast home. When Le Guin was a child, her parents taught her about myths and legends from around the world. "My father studied real cultures and I make them up," she once said, "in a way, the same thing."
Le Guin attended Radcliffe College, receiving her B.A. in 1951, and her master's degree in romance languages from Columbia University in 1952. Her thesis dealt with Romance Literatures of the Middle Ages and Renaissance, particularly French. Le Guin studied on a Fulbright scholarship in France, where she met Charles Le Guin, a historian. They married in 1953 and eventually settled in Portland, Oregon, where they rised their three children. The imaginary central European country, Orsinia, she created already as a young adult. Le Guin's other imaginary worlds include Earthea, Hainish, Orsinia, and the West Coast.
Before publishing her first works of non-fiction, Le Guin was an instructor in French at Mercer University, Georgia, in 1954 and at University of Idaho, Moscow, in 1956. In 1954 she was a department secretary at Emory University, Atlanta. Le Guin's first short stories appeared in the early 1960s. She had also written poetry.
Le Guin has taught writing at Pacific University, Forest Grove (1971), University of Washington, Seattle (1971-73), Portland State University, Oregon (1974, 1977, 1979), in Melbourne, Australia (1975), at the University of Reading, England (1976), Indiana Writers Conference, Bloomington (1978, 1983), University of California, San Diego (1979), and Kenyon College, Tulane University. Among Le Guin's several awards are Hugos (1970, 1973, 1974, 1975, 1988) and Gandalf Award (1979), Nebulas (1969, 1974, 1974, 1990, 1995, 2009), Janet Heidinger Kafka Prize for fiction (1986), a Pushcart Prize (1991), a National Book Award (1973) for the novel The Farthest Shore (1972), part of Le Guin's Earthsea trilogy, a Newberry Silver Medal (1972), and Harold D. Vursell Award (1991).
As a novelist Le Guin made her debut as in 1966 with Rocannon's World, about a scientist who tries to save a colony from hostile alien invasion. Her first fantasy tale, 'April in Paris', was published in Amazing Stories in 1962. In the story figures from different historical periods travel to 15th-century Paris to meet and marry; the theme of journey was further developed in subsequent works.
Rocannon's World was set in the Hainish universe, which is unified by her concept that an ancient civilization "seeded" the habitable worlds. The descendants of people from the planet Hain, remotely related forms of humanoids, inhabit our part of the Galaxy. However, psychologically and sociologically the various sentinent races are very diverse. The series, which spans 2500 years of future history, continued in Planet of Exile (1966), City of Illusions (1967), and The Left Hand of Darkness, which the author herself had described as a "thought experiment". Four Ways to Forgiveness (1997) was comprised of four Hainish connected novellas. The fifth novel in the Hainish sequence, The Dispossessed (1974), is considered among Le Guin's best works. Lavinia (2008), based on the last six books of Vergil's Aeneid, gave a voice to the Italian pricess, who married the hero of the Troyan war, but who never says a word in the epic. "As far as I know, it was my poet who gave me any reality at all," says Lavinia, the narrator. "It was he who brought me to life, to myself, and so made me able to remember my life and myself..." In spite of being a historical novel, Le Guin had argued that there is not a great difference between Lavinia and her scince fiction stories – both science fiction and historical novels draw on facts and imagination.
Le Guin's Earthsea trilogy, A Wizard of Earthsea (1968), The Tombs of Atuan (1971), and The Farthest Shore (1972), received a wide critical attention. The protagonist is Ged, also called Sparrohawk, whom the reader meets as a young magician, then at the height of his powers, and as the aging Archmage in the third part. After an interval of nearly twenty years, Le Guin continued the series with Tehanu (1990), Tales from Earthsea (2001), and The Other Wind (2001), a tale of dreams, aging, death, and the healing of old wounds. The story is set on an archipelago on an ocean world. Ged releases into the world a nameless shadow, an evil power from the realm of the dead, which he must chase and battle with to the ends of the earth. In the encounter he finds out that it bears his own name. In the second part Ged is seeking the missing half of a talismanic ring. He is captured and entombed in an underground labyrinth, where the young High Priestess Arha, also called Tenar, has devoted herself to death. Ged must persuade her to choose life to save himself and the world. The Farthest Shore depicts Ged's and his companion's, a future King, quest to find out why the power of all the magicians in the world is failing. They encounter a corrupt magician who has made a hole in the barrier between life and death. Ged closes the hole, but loses his powers as a magus. As in several of her works, the theme of journey becomes a metaphor for self-discovery and wholeness.
Le Guin's work reflected the Taoist principle mutuality (as in yin and yang), interdependence, and ordered wholeness. In A Wizard of Earthsea, her first fantasy novel, Le Guin examined the Jungian concept of shadow, representing those aspects of the whole self which have been denied. Also in her essay 'The Child and the Shadow' (1975) Le Guin has argued the importance of understanding of the Shadow. In Tehanu: The Last Book of Earthsea the struggle between good and evil continues but on a more realistic level. It also rejected the male centered heroism, perhaps as a result of feminist critic. This time the central character is the aging Tenar. She is fostering a damaged child, her adopted daughter. Ged's and Tenar's relationship is developed further, and at last they consummate their love.
The Left Hand of Darkness used ambisexual aliens to comment on humans' sexual mores. Genly Ai is an emissary from the human galaxy to a snow-bound planet, Gethen (called Winter by the Ekumen), whose people are androgynous. Normally they are neutral, but they have the capability of becoming either male or female at the peak of their sexual cycle. During a long journey across the ice with Estraven, whom he has regarded as a male, Genly Ai finally understands his Gethenian companion, and rethinks his attitudes and the nature of sex.
In The Dispossessed the values of an anarchist world, Anarres, are contrasted with those of primarily capitalist. Anarres is a barren, small moon, from which the hero, an Anarresti physicist Shevek, starts his journey to Urras, the mother planet. Shevek's tries to develop a general theory of Time, which would re-unite the estranged societies. Shevek is not completely at home in either society. He finds that the culture of Urras is more alienating than on his home world. After finishing his work he returns to Anarres, seeing that its era of cultural isolation is coming to end.
The high quality of Le Guin's work has been praised even by critics, who are not devoted readers of fantasy or science fiction. In her writing guide, Steering the Craft (1998), she challenges the general opinion to conflate story with conflict, although the writing process, discovering, finding, losing, could lead to it. The role of the narrative sentence, Le Guin argued, is to lead to the next sentence and to keep the story going. "I do have a kind of basically bleak and tragic take on things," Le Guin has said. "It's hard not to. But that doesn't mean I don't want my kids and grandchildren and everybody else's kids and grandchildren to stay alive and lead a good life. Survival instinct is strong. And I think you don't survive unless you cultivate hope and the reasons for hope." (Le Guin in an interview with Amazon.com, 2000)
The Telling (2000), which continues her Hainish cycle, is a story of a spiritual pilgrimage of a woman, Sutty, who studies the culture of a remote mountain region on a planet ruled by a dictatorial Corporation. "The Commander-General of the Hosts of the Lord announced the bombing while it was in progress, as an educational action. Only one Word, only one Book. All other words, all other books were darkness, error. They were dirt. Let the Lord shine out! cried the pilots in their white uniforms and mirror-masks, back at the church at Colorado Base, facelessly facing the cameras and the singing, swaying crowds in ecstasy. Wipe away the filth and let the Lord shine out!" (from The Telling) Sutty records much of what has been banned, trying to preserve the lost past. Again women are the preserving force, in a world dominated by male destructiveness. Gifts (2004) and Voices (2006) are parts of the Annals of the Western Shore. The third volume in the series, Powers (2007), about a runaway slave gifted with impeccable memory, received the Nebula Award.

Freak Squid Fossil

 The Squid called Logili Pealii,,From Biologist,, Araan Money's

ok now i'm description this post.....be careful



In a hangar-like research building at the Woods Hole Oceanographic Institution (WHOI), biologist T. Aran Mooney is exploring virtually uncharted waters: Can squid hear? Is their hearing sensitive enough to hear approaching predators? How do squid and other marine species rely on sound to interact, migrate, and communicate? Will the burgeoning cacophony of sound in the ocean disrupt marine life's behavior and threaten their survival?
"The sound in the ocean is increasing…commercial shipping, oil and gas exploration…those make a lot of noise," Mooney says. "And you don't know how that is going to affect the animal unless you know what it hears."
Mooney, a postdoctoral scholar at WHOI, has undertaken seminal investigations into the hearing of this seminal creature in the marine food web. His study is published Oct. 15, in the Journal of Experimental Biology.
"Almost every type of marine organism feeds somehow off the squid," says Mooney. Not just fish, but also many birds, seals, sea lions, and dolphins and toothed whales depend heavily on squid. Whales, according to Mooney, consume some 320 metric tons of squid a year; people eat another 280 metric tons annually.
Mooney says it may be the squid's role as a predator's entrée that holds the key to understanding the importance of hearing among squid and other ocean creatures. This is because predator avoidance is a key pressure for evolving hearing capabilities. If you can hear your predators approaching, you have a better chance of avoiding them. Eventually, he said, a better understanding of how squid hear may shed light on human hearing as well.
Despite their importance in the marine food web, little is known about how well squid hear and whether they rely on hearing to navigate, sense danger, and communicate with each other. Until recently, it wasn't clear that they even hear at all.
It is known now, through the work of Mooney and others, that the squid hearing system has some similarities and some differences compared to human hearing. Squid have a pair of organs called statocysts, balance mechanisms at the base of the brain that contain a tiny grain of calcium, which maintains its position as the animal maneuvers in the water. These serve a function similar to human ear canals.
Each statocyst is a hollow, fluid-filled sac lined with hair cells, like human cochlea. On the outside of the sac, the hair cells are connected to nerves, which lead to the brain. "It's kind of like an inside-out tennis ball," Mooney said, "hairy on the inside, smooth on the outside."
The calcium grain, called a statolith, enables the squid to sense its position in the water, based on which hair cells it's in contact with at a given moment. Normally it rests near the front of the sac, touching some of the hair cells.
When a squid moves quickly -- as it does when it flees an approaching predator -- the heavy calcium stone lags behind slightly before catching up to the hair cells. "Kind of like your stomach on a roller coaster," Mooney said. "The hair cells are very sensitive and can detect the calcium statolith lagging behind, then catching up."
Structurally, the statocyst "is analogous to our auditory system," said Mooney, who began his hearing research while working on his Ph.D. at the University of Hawaii. The statocyst, he thinks, "is on its way to becoming an ear" like the more familiar ears of vertebrates.
But to what extent does it function as an ear? "One of the obvious questions is, 'Can this acceleration-sensing 'ear' to also detect sounds?' Then, if they can hear sounds 'Do squid hear their predators coming?' " Mooney asked.
To find out if squid have true, functioning "ears," Mooney tests whether the nerves coming from the statocysts send impulses in response to sound. He anesthetizes a squid and attaches an electrode just under the skin near the nerves that extend from the statocysts. He attaches another sensor into the squid's back to get baseline measurements of electrical signals, because that part of the body should not respond to sounds.
He then lowers the squid into a shallow, 3-foot-wide tank. Also in the tank is a speaker that can emit a broad range of sound frequencies -- pure tones repeated about 1,000 times for each frequency. He then records the 1,000 responses to each. Averaging those 1,000 responses reduces the natural, random electrical noise in the body yielding the electrical signals, in millivolts, that occur along the nerves after each tone. This hearing test method is similar to those used to checking hearing in human infants.
His preliminary findings indicate that nerve responses showed the squid "actually do hear," he said. "But they only hear up to a certain frequency, about 500 Hz, which is pretty typical of a lot of fish that don't hear very well." Humans hear from about 20-20,000 Hz. Squid also do not detect the very high frequency sounds of dolphin echolocation clicks.
That may help explain why squid are such a prolific food source: They may not always hear well enough to get out of the way of approaching predators. But when Mooney and his post-doc advisor [name?] put the squid in a CT scanner, they found that squid may avoid predators in another way: they are almost the same density as water. That is, when squid were scanned in water, the CT could not image the squid body, illustrating that squid are nearly transparent to sound. This would likely make them very difficult for echolocating predators to detect. So, perhaps, squid could not take the evolutionary leap to adapt ears to detect very high frequencies, but being close in density to water is advantageous for several reasons, including avoiding predators.
Still, its auditory mechanisms have been good enough to make squid successful in an evolutionary sense. What, then, is the main purpose of the squid's hearing system?
Mooney said his work falls under the heading of "sensory biology," the study of how animals use their sensory systems to figure out the world around them. After the initial tests to see how sensitive squid are to sounds and their frequency range, he next studies will be to try to determine how important those abilities are to the animal. Do squid rely on sound to interact, migrate, communicate?
In one set of experiments Mooney will move the speakers to different positions and measure the nerves' response to see if they sense the location of that speaker.
"It's been suggested that a primary evolutionary drive behind hearing is to locate where the sound source is," he said. "If your mother is calling to you, you have to know where your mother is. If there's a predator coming you'd better darn well know where that predator is coming from so that you can get out of the way."
Another question Mooney wants to pursue is how much -- if at all, squid are affected by sounds of human origin in the ocean. Loud sounds, whether a sudden explosion or continuous ship traffic, might cause squid to migrate unnaturally just to escape the racket.
Mooney also thinks squid statocysts can tell scientists a lot about how ears originated and evolved.
"Humans, fish, and lots of animals use hair cells to detect sound and movement. Their hair cell structures are similar to squid, but also quite different," said Mooney. "There is probably a basic structure which evolved millions of years ago, but vertebrates and invertebrates have taken quite different evolutionary paths since.
"By learning more about squid hearing and squid hair cells, we might learn what is important in human hearing and human hair cells, or other animals for that matter," he said. "Down the road, squid ears and hair cells might be models for examining human hearing. But that's just speculative right now. We need to learn more about the basic functioning of squid ears first."
Paul Nachtigall, a biologist at the University of Hawaii who advised Mooney on his doctoral research on hearing and echolocation in whales and dolphins, said Mooney's research on squid hearing mechanisms and the ecological uses of hearing in squid are "groundbreaking."
"Aran was launched out of here with great success," said Nachtigall, "and his rocket appears to have reached stage two prior to reaching a stellar orbit."
Mooney's work with squid is funded by The Grass Foundation and a WHOI Independent study award from the Andrew W. Mellon Fund for Innovative Research.

Coccolithophore Blooms

This Observation from Dr.Stuart Painter between january-december time

Coccolithophores are key members of the marine phytoplankton community. They are abundant in the sunlit upper layer of the world's oceans, often forming vast blooms that can be seen from space.
"Coccolithophores are a complex group of plankton and in many areas of the World Ocean satellite-based observations provide the only information we have. We often have little direct knowledge of the environmental factors coincident with these blooms," explained Painter.
To understand the environmental factors controlling the development of coccolithophore blooms, Painter and his coauthors joined a cruise led by Dr William Balch of the Bigelow Laboratory (Maine, USA) and measured the salinity, chemistry and nutrient levels of the waters overlying the Patagonian Shelfand the shelf break, where the seafloor dips down to the deep seabed.
They also took measurements at the Brazil/Falklands Confluence to the northeast, where two major currents collide. These are the Brazil Current, which carries warm, saline subtropical waters southwards, and the Falklands Current, which brings cold, fresh and nutrient-rich water up from the sub-Antarctic region.
The continental shelf itself experiences strong tides and inputs from large rivers. And to complicate matters further, low-salinity water also enters the Patagonian Shelf region from the Pacific Ocean through the Magellan Strait in the south.
"The marine environment of the Patagonian Shelf region is well known for its complexity but what has been less clear until now is how this relates to the large blooms of coccolithophores in this region," said Painter.
He and his collaborators identified five distinct water masses, each having different characteristics, such as temperature and nutrient concentration. These water masses also varied in the amount of chlorophyll in their surface waters, indicating different levels of phytoplankton production.
During the research cruise, a large bloom of the globally ubiquitous coccolthophore species Emiliania huxleyiformed in the sub-Antarctic Shelf Water (SSW), north of the Falkland Islands. The bloom extended north along the shelf break and coincided with the distribution of reflective calcite detected from space, which was otherwise diffusely distributed. Calcite is a carbonate mineral and a common constituent of limestone. It also forms the microscopic plates -- 'coccoliths' -- that surround coccolithophores, possibly for protection.
Chemical and nutrient measurements confirmed that conditions within the SSW were especially conducive for coccolithophore bloom formation, with the right cocktail of nutrients and seawater temperature.
However, the distribution of the SSW is strongly influenced by the shelf break front, which is the focus of intense biological production. It can vary from 20 to 200 kilometres in width determining exactly where conditions are right for coccolithophore blooms.
"The complex interaction of large currents and different water masses clearly exerts strong controls over the position of coccolithophore blooms in this region,"said Painter.
The research was carried out 2008, during the period of peak coccolithophore abundance (December), while aboard the America research vessel Roger Revelle. Remote sensing data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument the Aqua satellite was acquired from NASA.
The researchers were Stuart Painter, Alex Poulton and John Allen of the National Oceanography Centre, Rosalind Pidcock of the University of Southampton's School of Ocean and Earth Science, and William Balch of the Bigelow Laboratory for Ocean Sciences, Maine, USA.
The Coccolithophores of the Patagonian Shelf (COPAS) research cruise was funded by the US National Science Foundation. Further financial support was provided by the US Defence Science and Technology Laboratory and the Natural Environment Research Council.

Ernest Rutherford Biography

    Comments


Ernest Rutherford


Ernest Rutherford was born on August 30, 1871, in Nelson, New Zealand, the fourth child and second son in a family of seven sons and five daughters. His father James Rutherford, a Scottish wheelwright, emigrated to New Zealand with Ernest's grandfather and the whole family in 1842. His mother, née Martha Thompson, was an English schoolteacher, who, with her widowed mother, also went to live there in 1855.

Ernest received his early education in Government schools and at the age of 16 entered Nelson Collegiate School. In 1889 he was awarded a University scholarship and he proceeded to the University of New Zealand, Wellington, where he entered Canterbury College*. He graduated M.A. in 1893 with a double first in Mathematics and Physical Science and he continued with research work at the College for a short time, receiving the B.Sc. degree the following year. That same year, 1894, he was awarded an 1851 Exhibition Science Scholarship, enabling him to go to Trinity College, Cambridge, as a research student at the Cavendish Laboratory under J.J Thompson. In 1897 he was awarded the B.A. Research Degree and the Coutts-Trotter Studentship of Trinity College. An opportunity came when the Macdonald Chair of Physics at McGill University, Montreal, became vacant, and in 1898 he left for Canada to take up the post.

Rutherford returned to England in 1907 to become Langworthy Professor of Physics in the University of Manchester, succeeding Sir Arthur Schuster, and in 1919 he accepted an invitation to succeed Sir Joseph Thomson as Cavendish Professor of Physics at Cambridge. He also became Chairman of the Advisory Council, H.M. Government, Department of Scientific and Industrial Research; Professor of Natural Philosophy, Royal Institution, London; and Director of the Royal Society Mond Laboratory, Cambridge.

Rutherford's first researches, in New Zealand, were concerned with the magnetic properties of iron exposed to high-frequency oscillations, and his thesis was entitled Magnetization of Iron by High-Frequency Discharges. He was one of the first to design highly original experiments with high-frequency, alternating currents. His second paper, Magnetic Viscosity, was published in the Transactions of the New Zealand Institute (1896) and contains a description of a time-apparatus capable of measuring time intervals of a hundred-thousandth of a second.

On his arrival at Cambridge his talents were quickly recognized by Professor Thomson. During his first spell at the Cavendish Laboratory, he invented a detector for electromagnetic waves, an essential feature being an ingenious magnetizing coil containing tiny bundles of magnetized iron wire. He worked jointly with Thomson on the behaviour of the ions observed in gases which had been treated with X-rays, and also, in 1897, on the mobility of ions in relation to the strength of the electric field, and on related topics such as the photoelectric effect. In 1898 he reported the existence of alpha and beta rays in uranium radiation and indicated some of their properties.

In Montreal, there were ample opportunities for research at McGill, and his work on radioactive bodies, particularly on the emission of alpha rays, was continued in the Macdonald Laboratory. With R.B. Owens he studied the "emanation" of thorium and discovered a new noble gas, an isotope of radon, which was later to be known as thoron. Frederick Soddy arrived at McGill in 1900 from Oxford, and he collaborated with Rutherford in creating the "disintegration theory" of radioactivity which regards radioactive phenomena as atomic - not molecular - processes. The theory was supported by a large amount of experimental evidence, a number of new radioactive substances were discovered and their position in the series of transformations was fixed. Otto Hahn, who later discovered atomic fission, worked under Rutherford at the Montreal Laboratory in 1905-06.

At Manchester, Rutherford continued his research on the properties of the radium emanation and of the alpha rays and, in conjunction with H. Geiger, a method of detecting a single alpha particle and counting the number emitted from radium was devised. In 1910, his investigations into the scattering of alpha rays and the nature of the inner structure of the atom which caused such scattering led to the postulation of his concept of the "nucleus", his greatest contribution to physics. According to him practically the whole mass of the atom and at the same time all positive charge of the atom is concentrated in a minute space at the centre. In 1912 Niels Bohr joined him at Manchester and he adapted Rutherford's nuclear structure to Max Plank's quantum theory and so obtained a theory of atomic structure which, with later improvements, mainly as a result of Heisenberg's concepts, remains valid to this day. In 1913, together with H. G. Moseley, he used cathode rays to bombard atoms of various elements and showed that the inner structures correspond with a group of lines which characterize the elements. Each element could then be assigned an atomic number and, more important, the properties of each element could be defined by this number. In 1919, during his last year at Manchester, he discovered that the nuclei of certain light elements, such as nitrogen, could be "disintegrated" by the impact of energetic alpha particles coming from some radioactive source, and that during this process fast protons were emitted. Blackett later proved, with the cloud chamber, that the nitrogen in this process was actually transformed into an oxygen isotope, so that Rutherford was the first to deliberately transmute one element into another.G. De Hevesy was also one of Rutherford's collaborators at Manchester.

An inspiring leader of the Cavendish Laboratory, he steered numerous future Nobel Prize winners towards their great achievements: Chadwick Blackett, Cockcroft and Walton, while other laureates worked with him at the Cavendish for shorter or longer periods: G.P Thompson, Appleton, Powell, and Asto. C.D. Ellis, his co-author in 1919 and 1930, pointed out "that the majority of the experiments at the Cavendish were really started by Rutherford's direct or indirect suggestion". He remained active and working to the very end of his life.

Rutherford published several books: Radioactivity (1904); Radioactive Transformations (1906), being his Silliman Lectures at Yale University; Radiation from Radioactive Substances, with James Chadwick and C.D. Ellis (1919, 1930) - a thoroughly documented book which serves as a chronological list of his many papers to learned societies, etc.; The Electrical Structure of Matter (1926); The Artificial Transmutation of the Elements (1933); The Newer Alchemy (1937).

Rutherford was knighted in 1914; he was appointed to the Order of Merit in 1925, and in 1931 he was created First Baron Rutherford of Nelson, New Zealand, and Cambridge. He was elected Fellow of the Royal Society in 1903 and was its President from 1925 to 1930. Amongst his many honours, he was awarded the Rumford Medal (1905) and the Copley Medal (1922) of the Royal Society, the Bressa Prize (1910) of the Turin Academy of Science, the Albert Medal (1928) of the Royal Society of Arts, the Faraday Medal (1930) of the Institution of Electrical Engineers, the D.Sc. degree of the University of New Zealand, and honorary doctorates from the Universities of Pennsylvania, Wisconsin, McGill, Birmingham, Edinburgh, Melbourne, Yale, Glasgow, Giessen, Copenhagen, Cambridge, Dublin, Durham, Oxford, Liverpool, Toronto, Bristol, Cape Town, London and Leeds.

Rutherford married Mary Newton, only daughter of Arthur and Mary de Renzy Newton, in 1900. Their only child, Eileen, married the physicist R.H. Fowler. Rutherford's chief recreations were golf and motoring.

He died in Cambridge on October 19, 1937. His ashes were buried in the nave of Westminster Abbey, just west of Sir Isaac Newton's tomb and by that of Lord Kelvin.
