He will not allow nobody to play in it but hisself and h built a high wall all round it and put up notice-board. The poor had now nowhere to play. The spring came and all over the country there were little blossoms and little birds. Only in the garden of the selfish Giant it was still winter . One morning he heard solme lovely music the King's musicians were passing by. It was a sight for him that spring came at last. Through a little hole in the wall the chldren had crept in and they were sitting in the brances of the trees. The birds were flying about and twittering with delight and the flowers were looking up through the grass and laughting. Only in one corner it was still winter . In it was standing a little boy.

Tuumapomm Autor: Rodion Krupin Juhendaja: Reet Ernits 9.Klass Tuumapommid · Tuumapomm on suure plahvatusjõuga lõhkekeha, kus energia vabaneb raskete aatomituumade lõhustumisel. · See on esimene väljatöötatud tuumarelv ja ainuke sõjas kasutatud tuumarelv. · Tuumapomm töötati välja Teise maailmasõja ajal USA-s Manhattani projekti raames. · Tuumarelvi on sõjaolukorras kasutatud kaks korda: Hiroshimas ja Nagasakis 1945. aastal. Tuumapommid · Tuumarelva kasutamistest hakkasid esimesena rääkima Inglise teadlased kaua enne teise maailmasõja puhkemist. · 1939. aastal teadsid juba kõik füüsikud, et sellist relva on võimalik luua. · Natsi-Saksamaal pidurdas uuringuid see, et parimad füüsikud olid kas hävitatud või põgenenud.

TUUMAPOOMID Hiroshimale, Nagasakile Hiroshima · 6. augustil 1945 heitis USA tuumapommi Hiroshimale Jaapanis. · Tohutu kuumus, lööklaine ja järgnenud tulekahjud hävitasid suurema osa linnast. · Hiroshima linna hävitas pomm nimega Little Boy (väike poiss). · Koheselt hukkus 20 000 inimest, hiljem on kiiritustõppe surnud rohkem kui 200 000 inimest. · Linna kohale aatomipommi viinud lennukit juhtis Paul W. Tibbets, kes suri natuke rohkem, kui aasta eest. Ta oli 92 aastane. Nagasaki · 9. augustil 1945 purustas teine aatomipomm teise Jaapani linna, Nagasaki. · See oli purustusjõult suurem kui 3 päeva varem Hiroshimale heidetud tuumapomm, kuid kahjustused olid väiksemad mägise maastiku tõttu. · Nagasakile sai saatuslikuks hea ilm, sest esialgu plaaniti visata pomm Kokura linnale. Seal olid aga ilmastikutingimused lendamiseks viletsad, seepärast otsustatigi hävitada Nagasaki. · Aa...

Aatompomm Aatompommi ülesehitus Tuumapomm ehk aatompomm on suure plahvatusjõuga lõhkekeha, kus energi vabaneb raskete aatomituumade lõhustumisel. Tuumapommi käivitamiseks on vajalik kriitilise massi olemasolu, muidu lendab enamus lõhustumisel tekkinud neutroneid ainest minema. Kriitilise massi vähendamiseks kasutatakse berülliumist neutronpeegleid. Ilma neutronpeeglita kriitiline mass on 11kg. Be neutronpeeglitega minimaalne kriitiline mass on 190g. Neutroneid peegeldab paari cm paksune Be kiht, mitte aga BE välispind nagu tavalisel peeglil. Ahelreaksiooni käivitamiseks kasutatakse implosiooni(sissepoole suunatud tugevat plahvatust). Implosioon muudab alakriitilise massi hetkeks ülekriitiliseks. Implosioon tekitatakse 3296 väikse läätsekujulise tavalähkeaine tüki üheaegse plahvatusega kerakujulise tuumapommi pinnal.

The Cement Garden - Ian McEwan Character Sketch - Tom Tom is the brother of the narrator of the story. He is the youngest child in the family. Tom was a 6-year-old little boy with pale skin. He had a bit big ears, black hair and his smile seemed idiotic. Tom was tender but mettlesome. Since he was the youngest child in the family he was mostly left out due to his age. Other siblings had their own activities together and Tom was too young to understand or take part. I.g. the game of scientists examining a specimen from outer space. His relationship with his father had changed after his father had become semi-invalid. After the incident Tom’s father was very severe with him. He felt like he had to compete for mother’s attention and frequently spited him with stinging criticism. Tom was afraid of his father. Tom’s mother was aware of the situation but did not ...

Raketid tänapäeva sõjarelvastuses Raketid jagunevad erinevateks liikideks. Liigitatakse neid väga mitut moodi: juhitavad ja mittejuhitavad, ballistilised ja suundraketid (ingl. k. cruise missile), samuti liigitatakse neid kasutusvaldkonna järgi (õhk-maa jne) ning strateegilisteks ja taktikalisteks. Kõige raskem ongi tihti mõista nende sõnade tähendust. Siinkohal siis mõned sõnaseletused: Strateegiline rakett on rakett, mis on enamasti suure hävitusjõuga ning kauge lennutrajektooriga. Strateegilisi rakette kasutatakse sõjategevuses suurte alade (linnade, sõjaväebaaside, lennuväljade) hävitamiseks. Levinuimateks strateegilisteks rakettideks loetakse just tuumarakette, mis suudavad kanda suuri tuumalõhkepeasid kasvõi teisele mandrile. Näideteks võiks tuua vene SS-25(pidil vasakul) ning USA ,,Peacekeeper" (eesti k. "Rahuhoidja" ; pildil paremal) raketid. Vasakul vene SS-25, paremal USA ,,Peacekeeper" ...

The narrator, an airplane pilot, crashes in the Sahara desert. The crash badly damages his airplane and leaves the narrator with very little food or water. As he is worrying over his predicament, he is approached by the little prince, a very serious little blond boy who asks the narrator to draw him a sheep. The narrator obliges, and the two become friends. The pilot learns that the little prince comes from a small planet that the little prince calls Asteroid 325 but that people on Earth call Asteroid B-612. The little prince took great care of this planet, preventing any bad seeds from growing and making sure it was never overrun by baobab trees. One day, a mysterious rose sprouted on the planet and the little prince fell in love with it. But when he caught the rose in a lie one day, he decided that he could not trust her anymore. He grew lonely and decided to leave. Despite a last-minute reconciliation with the rose, the prince set ou...

If you have created something, then try to be open minded Teacher: O'Mahony V.PG 11A 09.03.2009 This written essay here is talking about my thoughts and facts of life, what is around us. First I thought that why is always easier to create something but to destroy is much harder. Exactly there have been so many wars in history. Everybody wanted to own a lot of countries and others had to fight for their created country. Also they started to teach young people to kill and protect their country with killing enemies. Also government tried to keep a low profile, if there were some wars in state. These are my thoughts of creating and keeping something. In the old times were many wars. Some states predominated over other weaker countries or states. Weaker countries had created their own and loved country and they wanted to live like that for a long time. But also stronger countries wanted to broaden their boards and...

Seventeenth Summer was the first novel published by author Maureen Daly in 1942. The book talks about a girl's first experience with dating and falling in love. (A seventeenth year old girl named Angie who falls for the popular boy Jack.) I think this book was really good. But it is a little bit slow book, it does not really have any action in it and it just more of a leisurely book to read. I liked the romance and the character development, I liked the simplistic nature of their love. It made me yearn for respect and honor, modesty and decency. I admire that slow courtship. The book itself I think was not fantastic, but overall, I felt good reading this book because it still had the romantic aspect but with a new approach to it.
Make-up I take care about my look very much. Most often I use beauty products like mascara and lip balm. I can't go out without wearing them. Ibid I always wear nail polish too. My nail polish colour depend on what I wear. So, if I wear red shoes, I will wear red nail polish too. I like 'big hair'. Every day when I wake up, I straighten and teasing my hair. Erst I wore hair clips, but now I don't. Sometimes when my hair are in a plait, I only wear topknot. If I could get a new make-up kit, it will be consist of mascara, eyeliner, different lip balms and lip glosses, mirror, face powder, rouge, oils, perfume and different eye shadows. I always wear make-up at school and I'll always have my make-up bag with me. My opinion is that, it's okay to wear make-up at school. My mom don't spent ages putting on make-up because she only wear mascara, little bit eye shadow, powder, rouge and lip gloss. I...

After a time on this diet, the boys at the table chose Oliver to go ask the head cook for more ...

Equality Equality is a very important subject in todays world. Even though people of all races, social statuses and of both sexes have more equal rights in just about everything today, than they have had throughout history, there are still many places in the world and lots of topics, where equality is still a big problem. The point of equality, is for everyone to have the same opportunities. In a society with perfect equality, everyone would be able to do what they want, no matter where they are from, how wealthy their parents are, what color their skin is and so on. A persons gender or skin color wouldn't matter, if he or she would apply for a job or candidate for a political position. The same goes for voting rights and the laws would also be the same for everyone. A good example of how modern countries have more equality among their citizens is the United States of America. Just 56 years ...

Bullying I hadn't faced the real bullying, I think I have really carried only some smaller bullying casts. I don't even know what to talk about. But well, we all make mistakes, sometimes bigger and sometimes smaller. I'm going to talk about a short story about bullying in my childhood in my other school. We had a really great class and almost everybody held together. But like in almost every class, there is someone different from others and that may cause them problems with the other people. We had very many these classmates who were a little bit bullied and couldn't stand for themselves. There was a girl, who wasn't very thin and that's the main purpose she was bullied. She wasn't very rich also and she lived only with her mother. The boys of our class called her "fat" and so on. She did a face like she didn't care but I know that she really did and it hurt her. I and some other of my friends ...
Tuumapommid Tuumapomm Tuumapomm ehk aatomipomm on suure plahvatusjõuga lõhkekeha, kus energia vabaneb raskete aatomituumade lõhustumisel. Lisaks tavalisetele tuumapommidele on olemas termotuumapommid ehk vesinikupommid, neutronpommid ja kombineeritud tuumarelvad. Tuumapommi käivitamiseks on vajalik kriitilise massi olemasolu, muidu lendab enamus lõhustumisel tekkinud neutroneid ainest minema. Kriitilise massi vähendamiseks kasutatakse berülliumist neutronpeegleid. Termotuumapomm Vesinikpommi südamikus on tavaline lõhustumis- tuumapomm. Selle lõhkemisel tekib ülikõrge temperatuur, mis käivitab termotuumareaktsiooni. Esimese vesinikpommi juures kasutati veeldatud deuteeriumi. Tänapäevastes pommides kasutatakse liitium-deuteriidi.

MY HOBBY My hobby is roller-skating. I roller-skate whenever I can cause roller-skating is my favorite hobby. This hobby got started when I was a little boy. I had always wanted my parents to teach me how to ride with roller-skates. Soon they got fed up and tired of my bagging to get some roller-skates. So they bought me a pair of roller-skates. So as soon as I could, I learned to roller-skate. I started with just standing still with them. Soon I could roller-skate across the street. Now I roller-skate just about everywhere where it's possible. The wonderful thing about roller-skating is that I do not have to buy a bus ticket. For example, I do not have to be in traffic congestion. Also I do not have to buy some lamellae tires to drive in winter because I can ride a bus in winter. I can ride in some indoor skating park at winter. Roller-skates provide the rider with so much information about balancing a...

Jonas' mother has an important job with the Department of Justice, and his father has a job as a Nurturer, taking care of newborns. Jonas has one younger sister, Lily. His family seems ideal.

Lily goes first by explaining the anger that she felt today when someone from a visiting group of Sevens, or seven-year-olds, did not obey the rules about waiting in line. She compares the bo...

Once upon a time there was a boy named Sebastian. He had a gorgeous mother, who was very kind and helpful, her name was Cassy. One late night an old woman came to their door. She was sick and dieing and she said: ''I know you are helpful. So I ask you, could you go Far Far Away and bring me green flowers? These flowers could help me to heal.'' Cassy agreed and said: ''I pack my suitcase tomorrow morning.'' Then she went to Sebastian and told him: ''I'm going to leave tomorrow morning and will be back after a week.'' Sebastian was in the bed and very sleepy, he couldn't understand and he thought this was just a dream, but in the morning he understood this was real. Cassy was already half way to Far Far Away when she reached ocean. At the beach she saw red bubbles shaped as big basketballs. Crossing beach made her journey much harder. Finally she reached Far Far Away. It was really snowy there. Despite the snow there were green flowers ev...
1. Usa 1950-1970 Mustanahaliste olukord Mustasi ja valgeid ei koheldud võrdselt, tihit neid kiusati või diskrimineeriti, mustad ei saanud vahel ka valida. Mustad ei tohtind ka olla samas asutuses valge inimesega või samas bussis. 1960 tuli murrangulisem uuendus ja hakkati neid vähem diskrimineerima. See probleem on siiski mureks siiani. Kommunismi leviku pidurdamine Usa hakkas pidurdama kommunismi levikut andes abi väikestele riikidele kes ei olnud veel kommunismi all, Usa viis neile süüa, andis raha ja andis teada et demokraatiaga jäävad nad vabaks. Hiljem hakkati ka seda enda riigis tegema millega piirati ka demokraatlike kodanike õigusi, see idee aga hüljati. Reaganoomika Tema uus majanduspoliitika andis ettevõtlusele suurema vabaduse, maksud vähenesid ja üldse enamuste piirangute tühistamist. Tema ideoloogias oli ka uuesti nsvl surve alla panna koos kommunismiga. Seda ideoloogiat ja uut reformi kutsuti Reaganoomikaks Pidurduspoliiti...
