The world's largest atom smasher's first experiment (1) which as they say will change the universe went off today without a hitch, paving the way toward the re-creation of post-big bang conditions. The Large Hadron Collider fired a beam of protons inside a circular, 17-mile (27-kilometer) long tunnel underneath villages and cow pastures at the FrenchSwiss border. Inside the control room, physicists and engineers cautiously shot the beam down part of the tunnel; (2) they have stopped it before it went all the way around. "Oh, we made it through!" one of the scientists cried (3) as they watched the beam make it through a further section of the tunnel. The first particles were sent (4) at 12 pm local time. One hour after starting up, on the first attempt to send the beam circling all the way around the tunnel, it …show more content…
"First of all, I didn't believe it," said Verena Kain, a European Organization for Nuclear Research (CERN) engineer. "I had to see it a second time, and I thought, Oh, wow, it actually worked! We’ve been through the prepping, the planning, (5) the run-throughs, etc, and it was great to run it for real.” (6) "You know things can go wrong at any time, but luckily this morning everything went smoothly," said Lyn Evans of CERN, who oversaw the building of the accelerator. (7) “We seen these huge events go wrong before.” The collider "was first proposed more than 20 years ago," said Django Manglunki, an accelerator physicist at the European Organization for Nuclear Research (CERN), on Tuesday. "We've been preparing that beam for more than ten years." It smashes together particles smaller than atoms at near-lightspeed to break them down (8) into it’s constituent parts and recreate conditions which

The "2nd U.S. Circuit Court of Appeals" held that those business practices that have had a disparate impact effect on the older workers are now considered to be actionable under one national anti-discrimination law (Hamblett, 2004). The case does reaffirm a second Circuit precedent that had been set but which is at odds with what a majority of federal courts have held. The appeals court supported the idea that a layoff plan had been properly brought under the The Age Discrimination in Employment Act of 1967 (ADEA) although the company did not have the intention of discriminating.
The eastern span was an incredible engineering feat as well. The cantilever bridge from Yerba Buena Island to Oakland was the longest bridge of its kind at the time. Yerba Buena Tunnel connected the western half of the bridge to the eastern half and measured 76 feet wide, 56 feet high, and 1,700 feet long. The spoils from constructing this tunnel were used in part to make Treasure Island. The foundations used in the east section differed from those in the west section because the bottom of the bay contained clay and was too deep to reveal bedrock. The steel superstructure of the cantilever bridge was the largest order for steel ever placed when the bridge was constructed. They built the bridge in two pieces, intending to join them in the middle. However, extreme temperatures from sunlight caused the side of the bridge facing the sun to expand while the opposite side contracted. When they were ready to join the two pieces, they did not initially fit.
Teller, who is a “Hungarian-born atomic physicist” and “known as the "father" of the hydrogen bomb”, was at the forefront when it came to the design of the Teller-Ulam Hydrogen Bomb (Hydrogen Bomb Exploded). Stanislaw Marcin Ulam, mathematician who developed the idea of the lithium hydride bomb, was the other half of that perfect combination. Although there was excitement for the U.S. being the first to be the bomb, some scientists did not share that excitement. Not all people agreed with the idea of building this bomb, some people had their doubts. For example, Julius Robert Oppenheimer was a highly known theoretical physicist and Director of the Los Alamos Laboratories.
The Little Albert experiment has become a widely known case study that is continuously discussed by a large number of psychology professionals. In 1920, behaviorist John Watson and his assistant Rosalie Rayner began to conduct one of the first experiments done with a child. Stability played a major factor in choosing Albert for this case study, as Watson wanted to ensure that they would do as little harm as possible during the experiment. Watson’s method of choice for this experiment was to use principles of classic conditioning to create a stimulus in children that would result in fear. Since Watson wanted to condition Albert, a variety of objects were used that would otherwise not scare him. These objects included a white rat, blocks, a rabbit, a dog, a fur coat, wool, and a Santa Claus mask. Albert’s conditioning began with a series of emotional tests that became part of a routine in which Watson and Rayner were determining whether other stimuli’s could cause fear.
CM: Not only are there hundreds of failed attempts, but there are thousands of scientists world-wide are experiencing hundreds of failed attempts.
The point of view was effective throughout the course of Tunnel giving us a better understanding of the elements happening. Tunnel is written in first person point of view, meaning that the pronoun “I” was used throughout the story. On page 44 this is seen. It states “I didn't know by the time I was sixteen it would be the global economy and there would be no summer jobs, even though you did your life-skills analysis as recommended by the guidance councilor.”

As they drive through the tunnel, Charlie begins living in the moment and soaking up what the present has to offer. Many times throughout his letters, Charlie describes the situations of other people and tries to sink deeper into the causes of their actions, but this drive marks the first time Charlie focuses on himself, his friendship and on how he is feeling infinite in that moment. He feels as if he and his friends can do anything or feel anything. He believes that happiness is not out of reach. The tunnel signifies hardships that Charlie has faced, but the light at the end of the tunnel signifies how he overcomes those obstacles. In the end he emerges with two friends that understand him more than his family ever

The largest and most powerful particle collider in the world, based in CERN on the border of France and Switzerland, it is a huge undertaking. It is built to assists the scientists in discovering what the Earth is made of; it also plays a crucial part in resolving many theories by scientists. It is a 27 kilometer ring with super magnets that help the particles speed along the way. Some people also argue that it’s a machine that could possibly be dangerous, because it has the capability of creating small BLACK HOLES! “One way or another, it's the world's largest machine and it will examine the universe's tiniest particles. It's the Large Hadron Collider (LHC).”

This arbitrary time could be in the past, before the particle was even generated, or even in the future. Therefore, if physicists see particles spontaneously appearing into existence before a collision in the collider even occurs, this could be indicative of the Higgs singlet decay particles appearing in our universe.
