The Large Hadron Collider and the Frontier of Physics

The science of particle physics looks at the very building blocks of matter — the atoms and particles that make up much of the material in the cosmos. Its a complex science that requires painstaking measurements of particles moving at high speeds. This science got a huge boost when the Large Hadron Collider (LHC) began operations in September 2008. Its name sounds very science-fictiony but the word collider actually explains exactly what it does: send two high-energy particle beams at nearly the speed of light around a 27-kilometer long underground ring. At the right time, the beams are forced to collide. Protons in the beams then smash together and, if all goes well, smaller bits and pieces — called subatomic particles — are created for brief moments in time. Their actions and existence are recorded. From that activity, physicists learn more about the very fundamental constituents of matter. LHC and Particle Physics The LHC was built to answer some incredibly important questions in physics, delving into where mass comes from, why the cosmos is made of matter instead of its opposite stuff called antimatter, and what the mysterious stuff known as dark matter could possibly be. It could also provide important new clues about conditions in the very early  universe when gravity and electromagnetic forces were all combined with the weak and strong forces into one all-encompassing force. That only happened for a short time in the early universe, and physicists want to know why and how it changed.   The science of particle physics is essentially the search for  the very basic building blocks of matter. We know about the atoms and molecules that make up everything we see and feel. The atoms themselves are made up of smaller components: the nucleus and electrons. The nucleus is itself made up of protons and neutrons. Thats not the end of the line, however. The neutrons are made up of subatomic particles called quarks. Are there smaller particles? Thats what particle accelerators are designed to find out. The way they do this is to create conditions similar to what it was like just after the Big Bang — the event that began the universe. At that point, some 13.7 billion years ago, the universe was made only of particles. They were scattered freely through the infant cosmos and roamed constantly. These include mesons, pions, baryons, and hadrons (for which the accelerator is named). Particle physicists (the people who study these particles) suspect that matter is made up of at least twelve kinds of fundamental particles. They are divided into quarks (mentioned above) and leptons. There are six of each type. That only accounts for some of the fundamental particles in nature. The rest are created in super-energetic collisions (either in the Big Bang or in accelerators such as the LHC). Inside those collisions, particle physicists get a very fast glimpse at what conditions were like in the Big Bang, when the fundamental particles were first created. What is the LHC? The LHC is the largest particle accelerator in the world, a big sister to Fermilab in Illinois and other smaller accelerators. LHC is located near Geneva, Switzerland, built and operated by the European Organization for Nuclear Research, and used by more than 10,000 scientists from around the world. Along its ring, physicists and technicians have installed extremely strong supercooled magnets that guide and shape the beams of particles through a beam pipe). Once the beams are moving fast enough, specialized magnets guide them to the correct positions where the collisions take place. Specialized detectors record the collisions, the particles, the temperatures and other conditions at the time of the collision, and the particle actions in the billionths of a second during which the smash-ups take place. What Has the LHC Discovered? When particle physicists planned and built the LHC, one thing they hoped to find evidence for is the Higgs Boson. Its a particle named after Peter Higgs, who predicted its existence. In 2012, the LHC consortium announced that experiments had revealed the existence of a boson that matched the expected criteria for the Higgs Boson. In addition to the continued search for the Higgs, scientists using the LHC have created whats called a quark-gluon plasma, which is the densest matter thought to exist outside of a black hole. Other particle experiments are helping physicists understand supersymmetry, which is a spacetime symmetry that involves two related types of particles: bosons and fermions. Each group of particles is thought to have an associated superpartner particle in the other. Understanding such supersymmetry would give scientists further insight into whats called the standard model. Its a theory that explains what the world is, what holds its matter together, and the forces and particles involved. The Future of the LHC Operations at the LHC have included two major observing runs. In between each one, the system is refurbished and upgraded to improve its instrumentation and detectors. The next updates (slated for 2018 and beyond) will include an increase in collisional velocities, and a chance to increase the luminosity of the machine. What that means is that LHC will be able to see ever more rare and fast-occurring processes of particle acceleration and collision. The faster the collisions can occur, the more energy will be released as ever-smaller and harder-to-detect particles are involved. This will give particle physicists an even better look at the very building blocks of matter that make up the stars, galaxies, planets, and life.

Mattel Case Study Free Essays

Recently Mattel faced challenges regarding their toys manufactured in China. They found out that these toys made in China have high lead content that can poison children. Mattel immediately recalled these toys, specifically: 253,000 â€Å"Sarge Cars,† â€Å"345,000 batman, 683,000 Barbie and Tanner sets and 1 million Doggie Day Care Sets (iVillage, 2007). We will write a custom essay sample on Mattel Case Study or any similar topic only for you Order Now Mattel immediately asked their retailers to recall these toys. How did the management of Mattel arrive to this kind of decision in order to solve this problem? This study will examine the decision process. Mattel believes in proper management is important to ensure the success of the company. And to be able to achieve it, a good manager is needed. Managers are vital ingredient of a company’s success because they are the ones responsible i company (Long, 1998). Ethics is also vital in an organization. Several times we hear about organizations being hit by scandal dealing with issues of ethics, integrity and trusty. In reality, several organizations are ethical and are not beset with scandal, lawsuits and investigations. The reason most organizations considered ethical are not dealing with this negative press is because many have instilled a culture of ethics and integrity. Since Mattel believes that ethics will be helpful to their productivity and survival, as contrast to what is perceived on television, for example, where people at all means do whatever they could to achieve something, even if it meant being dishonest. (p. 208) Mary Guy (1990) wrote that individuals who are considerate with regards to making ethical decisions influence the new comers of the organization, and will later on develop their own sensitivity on ethics. (p. 161) Ethics requires the decision maker to consider things based on important values. (p. 5). According to Jacobs and Jaques (1987), the skill requirement at the organizational level requires ethics because it is responsible for the organization’s reputation of their products and services. The company should respond to the social and community needs and it should also be concerned with public relations. (p. 31) The influence of ethics in decision making is crucial because the company or organization judges a situation based on what is morally right and fair for their clients or consumers. Not only will they lose their regulars if they fail, but they will also lose potential patrons (McGregor, 2004). They also base their decisions on how wise it should be. Seldom are there companies who are gearing towards unethical decisions just for the sole reason of achieving a goal (Minor, 2002). Usually, success comes with the right, ethical, decisions; and it has been proven for many years that is why organizations are required to make these sound judgments. References Guy, M.E. (1990).
