The discovery of the Higgs Boson - Part 2 It was a very complicated procedure to prove the existence of the Higgs boson. High energy in a particle accelerator was needed therefore. Two particles nearly at the speed of light had to be smashed together, as a result of the collision more massive particle could pop into existence. The CERN physicist set themselves a high statistical standard before the claim the existence of the Higgs Boson. Due to the fact that they could detect the phenomena on two independent detectors the certainty that the particle really exists is statistically much higher than they aimed. The Higgs particle and the closely related Higgs field are the reason why the universe unfolded after the Big Bang in this way it is and not in a sea of massless particles. Nanoseconds after the Big Bang the Higgs field slowed down some of the particles which were flying around. With this slowdown the particles got mass. After this they were able to stick together and then the particles could combine and congeal into atoms and molecules. Not all the particles slowed down. Some, like photons, flew through the Higgs field and they still have no mass. The next step for scientists is now possible. That could be for example the discovery of extra dimensions of space and time to massive, secretive particles that shadow those already known. At the end of the article it is explained that it is not yet clear, if the particle they found is exactly the Higgs which do have the behavior that they expect. The next upgrade from the LHC, which will provide more than 50 percent more energy, may give answers of a lot remaining questions, like this or others like the evidence of supersymmetry. Personal Comment: In my opinion, the work that the scientist did in Geneve in the last years is now crowned with a big success. What I really cant understand is, that it is not more discussed in your medias. It is a discovery which will have a big influence into the work of scientists in the next years.

The discovery of the Higgs Boson - Part 1 Hi there, i have to write a summary for university. I was allowed to choose the topic myself. It would be nice, if someone could correct my text. It is not necessary to read the original text. Problem is, at least i think so, my gramma. part 1: “Higgs discovery helps make sense of matter”, Alexandra Witze, December 13, 2012 available at http://www.sciencenews.org/view/feature/id/346991/description/Higgs_discovery_helps_make_sense_of_matter Summary The article generally deals about the discovery of the Higgs Boson. The Higgs Boson is a particle that scientists had been hunting for years. Finally in 2012 they could detect it in the LHC ( Large Hadron Collider) at the CERN laboratory near Geneve. The name from the particle comes from a scientist who dreamed up the idea amongst others. In the first part of the article the thrilling moments before the first presentation of the discovery is described. Finding the particle was in many ways the climax of decades of scientific working. It helps explain mass. Due to the finding of the Higgs physicists can now fully explain why the universe looks the way it does. They have made the finishing touches on a complete theory of matter, which we can see around us.

I am here again :) I was not here for 6 months now. I will try to do more here again. I have to write some homeworks for university. What do you think is the best way to get them corrected? Should i just put them in here in the notebook entry? The content is not difficult, just some summaries, a CV, and things like that. On the other hand I would be happy if I could help someone with the german language.

Hong Kong hi everybody, i am searching for someone who lifes in Hong Kong, or someone who knows a few things about Hong Kong. My interests are for example how much does a flat cost ? How much do you need about for living there per month. (Is food expensive) ? Does anyone know someone, who could eventuelly answer such questions ?

Today Today it is another borring rainy day here in austria. But there is a ray of hope, when i look outside my window here. Everything is going to be green. A wunderfull deep, luscius, rich green. Spring comes, hooray. :) First little yellow, pink and white flowers coming out of the meadow. I don´t know the names in english. I just can tell you they are wonderfull. Yes, really wonderfull after months of coldness, darkness, dampness and snow. No wonder when some people get depressive. But now it´s over. The first messengers of warmness are here. Summer forever ! I like it. :-)

My english teacher - a funny person Today i had english course. Our english teacher is, for my understanding, a typical english guy. He lived in Manchester, and is an enthusiastic Manchester United fan. And he has the typical english humor. (very funny,...sometimes ;-) ) But there is one thing i absolutely cannot understand: He hates sunshine and he likes rainy days ! That confuses me absolutely. I asked him two times: " Is that real, or are you joking". And each time he said: "That´s no joke". Are all the people in britain so strange ? Hm,... i think so. Maybe it is the reason why it often rains there. It is not a fine day, when it is just cloudy, foggy, noisty and awful cold. No, it is only perfect when it is raining additionaly. Yes, i want to learn english, but i think i don´t want to learn this lifestyle. ;-D

Hi at all This is my first entry. I try to improve my spoken english. Therefore i am looking for guy´s, who are interested to skype with me. So, they can help me in english and i help them in german. But it is not easy. Perhaps they are a little bit shy. There are so many people here, who are willing to write. But sadly there is no one, who is willing to speak with me. But i will not give up. I will continuing report here. :)

Double negation Hi everybody :), I love the song "All summer long" from Kid Rock. But there is one sentence in the second verse, i am not sure what it means, he sings: "We didn´t have no internet,.." I am from austria, - so i speak german-, in german language this is an double negation. Because of this, the german meaning of this sentence is that he had internet. So, my question is, is the song text correct, or is there a mistake in it, or is double negation in english the same meaning as one netation and finally: Did he have internet or not ?
