The world's largest atom smasher used its accelerator Tuesday to speed up proton beams for the first time as scientists moved ahead in efforts to learn more about the universe. Experiments like this are "aimed" at finding out about the nature of the universe. What is everything made of and how is it put together?
This is the latest in a long stream of experiments that have been unlocking the secretes of what we are made of.
For this project yous should read this article (copy this link and go to the site: http://news.yahoo.com/s/ap/20091124/ap_on_sc/eu_sci_big_bang_machine/print ) and then write a paragraph that summarizes the article. Paragraphs should be at least three well constructed sentences.
Next you should find and link to an article about a different endeavor to find out more about the nature of the atom. There have been experiments going back over 100 years to try to find out more about the atom.
Finally write a paragraph summarizing the material in that article. Again, paragraphs should be at least three well constructed sentences.
Finally write a paragraph summarizing the material in that article. Again, paragraphs should be at least three well constructed sentences.
Make sure you put your ID and class section on your work. This project is due by midnight Sunday, 12/13. Remember that you need at least one project out of every two. If you did not do the previous one, you must do this one. If you do both projects one will count for extra credit.
If you have problems, email me at aphsbio at gmail.com. Make sure that you tell me what your problem was, and you can include your completed project.
A few weeks ago scientists used a ten billion dollar large Hadron Collider to speed up proton beams. The beams were traveling at almost the speed of light around a seventeen mile tunnel under the swiss-french border. The beams were traveling in super cold temperatures. The goal of the collider is to create the same conditions about one trillionth to two trillionths of a second after the big bang. It will also be used to study things such as dark matter and antimatter.

Ernest Rutherford's famous gold foil experiment is quite possibly one of the most famous experiments in chemistry. Rutherford shot alpha particles from a radioactive source in a lead box with a hole in it. The particles shot through a thin piece of gold foil. Many particles went right through the foil but some were deflected. This suggested that atoms have an extremely small nucleus and a lot of empty space around this nucleus.

A few weeks ago scientists used the world's largest atom smasher to speed up proton beams at an attmept to learn more about our universe. The $10 billion Large Hadron Collider gave off the proton beams moving at roughly the speed of light. The beams traveled underground around a 17-mile tunnel under the swiss-french border. The beams traveled in oppostie directions through pipes at very cold temperatures. The first collisions are used to calibrate the machine, later colissions will be used to help scientists learn about the make-up of the universe. The machine can help the scientists learn about particles and forces.

Ernest Rutherford was known as the father of nuclear physics. Rutherford discovered that atoms have a positive charge in a nucleus. Ernest Rutherford created the Rutherford model otherwize known as the planetary model of the atom. Through his discoveries he came up with Rutherford scattering through his gold-foil experiment. In this experiment Rutherford tried to better learn about the structure of the atom. Rutherford shot a beam of alpha particles at a very thin sheet of gold-foil. The sheet was surrounded by zinc sulfide used as a detector. Most of the alpha particles passed through however a small percentage hit and bounced back. Rutherford came up with the conclusions that the atom was mainly empty space with a nucleus in the center.

The L.H.C. is the worlds largest atom Smasher. It is located in Geneva, Switzerland and cost $10 billion. The proton beams the machine creates are shoot through pipes at the same time in opposite directions and are almost as fast as the speed of sound and are colder than outer space. The scientists want to create conditions that were similar to right after the Big Bang happened so they can see how our universe was created.

Ernest Rutherford was a chemist and physicist from New Zealand and considered to be the "Father of Physics". He found out things about atoms that weren't know before such as atoms have positive charges because of a small nucleus and many things that do with elements. He studied and did experiments to learn more about alpha and beta rays. In 1910, he did research to learn about nature of the inner structure of the atom and what caused scattering of alpha particles led him to his concept of the nucleus, his greatest contribution to physics.

Recently, Scientists in Geneva, Switzerland were able to show that the Large Hadron Collider could raise the power of the proton beams it accelerates
ReplyDeleteby an extra 20%. This is good news for the scientists because last year the collider collapsed and took a lot of time and money to repair. The main goal of the project is to create the same conditions as were around 1 or 2 trillionths of a second after the big bang. With this new technology scientists hope to understand dark matter and antimatter and discover the Higgs boson.
a Higgs boson...what?
Scientists at the Fermi National Accelerator Laboratory in Chicago hope to observe the elusive elementary particle some time in the near future with the help of the Large Hadron Collider in Geneva.Also by finding more qualities of the Top Quark scientists think it may help them find the Higgs boson. The Higgs Boson is a particle first thought of in the 1960's and helps explain how the basic elements of the universe interact and fit together. The Higgs boson has not yet been observed so is still theoretical and is not observed with the prediction made by the correlation of the 2 colliders it would show a major flaw in the current model.
the above comment was SB
ReplyDeleteRecently scientists have made an effort to learn more about the universe and were successful. They used the world’s largest atom smasher‘s accelerator to speed up proton beams for the first time. The large hadron collider worth 10 billion dollars showed in can raise the energy of proton beams speeding around the enormous machine. The latest phase was when the first proton beam circulated through the 17 mile tunnel in the swiss-french border. Ultimately the goal of the collider is to create conditions like they were 1 trillionth to 2 trillionths of a second after the Big Bang.

In 1928 John Cockcroft and E.T.S Walton from Cambridge, England began trying to split an atom. They eventually split the atom and fragments flew. They realized that the energy that was released was a conversion of mass into pure energy. This was astonishing because Einstein predicted this exact phenomenon. In 1951 Cockcroft and Walton were awarded the noble prize in physics for his work of the accelerated particles to study the atomic nucleus.

This article is about the world’s largest atom smasher. It showed it can increase proton beam rate by 20 percent. Scientist were able to get the beams going in two different directions. The first science test will be held in January or early February. The main goal is to run the beams at 7 TeV in both directions.

Ernest Rutherford was a scientist that made many advances having to do with the atom. He used his gold foil experiment to show that an atom was made of mostly empty space. He won a Nobel Prize in Chemistry for this discovery. He’s also credited for splitting an atom and the experiment of splitting a nucleus with the help of two of his students.
