Particle accelerators are considered hallmark of human technological advancement. Colliding subatomic particles in high energies, particle accelerators have brought dramatic paradigm shift in our understanding of the universe. Accelerators generally collide energetic particles together and look for the change in the energy of the system. This measurement of energy in colliding particles plays a vital role in the understanding of the events occurring inside the particle accelerators. Understanding the effect of particle accelerator in the human society is incomplete without the discussion of the energies that are involved in the accelerators.
Particle accelerators, as its name suggest, accelerate particles and after those particles have reached certain amount of energy, they collide them. The amount of energy required in the particles depends on the products the physicists want and the initial conditions of the experiment. If the accelerator is about to collide two like charge particles( e.g. proton pair) , then those particles must have enough kinetic energy so that they could overcome their electrostatic repulsive force and reach close enough for the nuclear force to be effective(~1fm). It is essential for all like charge particles to pass this threshold electrostatic potential energy, called the Coulomb barrier, to undergo anything nuclear in nature. On the other hand, if a physicist wants to produce pion (π0 or π+) by colliding two protons (p), it is essential for the protons to have enough kinetic energy that the energy from the collision is enough to create a particle with the desired rest mass, as given by the mass energy equivalence relationship. The threshold energy for the protons to create a pion with rest mass of 135M...

...llisions will not only elevate our lifestyle but also define ourselves in the process. Finding answers to mindboggling question just by colliding particles together, in a way shows how capable humans are. We should never get tired of this study about the universe, it defines what we are.

Einstein's equation "E=mc^2" has two sides which is constructive and destructive. The constructive side is when energy is converted into mass and the destructive side is when a small amount of mass is converted into energy. According to Einstein’s equation, the physicists of the Manhattan project hypothesized that a minute mass ...
...vercome, there is more of a chance to capture such great discoveries. People need to realize that if they never take the time to stop and look around, appreciate the small things in life, they might miss out on important details and or moments that the world has to offer. Scientist didn’t obtain their greatest discoveries by looking at the world with a closed mind. During the months of September through Novemeber, the leaves start to fall off the trees. It is obvious its fall, but what else is occurring? Gravity. Albert Einstein discovered gravity by watching and ordinary object fall. At that moment he became a scientific unscrupulous observer.
There were many a times when the individuals in the documentary Particle Fever by Mark Levinson, encountered problems. These problems hindered their success in the making of the Large Hadron Collier that would be used to discover new particles in the universe. For instance, when Large Hardon Collier began to leak of helium, the team of theorists and experimentialists: Fabilola Gianotti, Martin Aleksa, and Monica Dunford did not become doubtful or aggravated but simply took a deep breath and proceeded to their project. They needed an explanation as to why the leak was caused and concluded that there was an excessive amount of power being used at once. After a few repairs were made due to damages caused by the leak, the team then used half the power of what was used before. The Large Hadron Collier began to run more efficiently than as it did with too much power and alas the team of theorists and experimentalists sighed with relief. Knowing that the life of a nurse is a challenging one, and being faced with problems occur continuously, regardless of the problems, I will use patience to help the ones in
In the 1920s the new quantum and relativity theories were engaging the attentions of science. That mass was equivalent to energy and that matter could be both wavelike and corpuscular carried implications seen only dimly at that time. Oppenheimer's early research was devoted in particular to energy processes of subatomic particles, including electrons, positrons, and cosmic rays. Since quantum theory had been proposed only a few years before, the university post provided him an excellent opportunity to devote his entire career to the exploration and development of its full significance. In addition, he trained a whole generation of U.S. physicists, who were greatly affected by his qualities of leadership and intellectual independence.
An underlying theme present throughout the series is the possibility that our existence is not the only one. According to current theories in physics, it is entirely possible that our universe is just one of many universes f...
There are still numerous possibilities and crossroads that have not been discovered but could create an energy

Quarks were first proposed in 1964. It was named quark by Caltech theorist Murray Gell-Mann. He named them that from a quotation in a novel “Three quarks for Muster Mark, Sure he hasn’t got much of a bark …”2 Gell-Mann said all mesons, baryons, and hadrons are made of quarks. He also said they are made of three types of quarks (up, down, and strange). That makes a total of nine types of quarks. George Zweig called them aces. Not many people believed in it at this time. From 1968 to 1973 MIT bombarded protons and neutrons with electrons. Electrons ricocheted off protons and neutrons as if it hit a hard, tiny object. The hard object was a quark. Over the years experiments and researches have led to a lot of indirect evidence that quarks exist.
Soon after this conversation the two return to the conference. Many decades later, further conferences still debate the value of physics and more questions are raised that would require both Hume and Kant to revise their arguments so that they address various issues. Of these includes that physics is slowly moving away from certainty and universality. Instead, it’s becoming probability based, even if many of the probabilities are astronomically high. Furthermore, now that we can detect energy transfer, Hume’s argument on causality is not nearly as strong. Finally, if physics and other sciences hold no genuine knowledge, how can we possibly apply the sciences to envision, detect, and create new objects?
There are 2 kinds of hadrons: baryons made up of three quarks and mesons made up of one quark and one antiquark. It has been discovered in recent years that hadrons are made up of not only three valence quarks but also made of baryons, mesons, antibaryons. . Among the particles that are classified as hadrons, protons within atomic nuclei and neutrons are stable. However, hadrons are unstable under normal conditions. For example, free neutrons decay within about 611 seconds, which is their
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).”
You know what really makes you and me alike? We are both made up of trillions and trillions of cells, and even smaller atoms. These atoms make up all everyday matter, and till the beginning of the 20th century many people thought they were the smallest building blocks of life. It was then discovered that they too have even smaller parts called subatomic particles. In short, these particles often have interesting characteristics that keep the universe running. Understanding these subatomic particles is crucial towards grasping the idea that all matter is related in spectacular ways. Without these particles we wouldn’t know about the most fundamental building blocks of life, and wouldn’t have particle physics in general. Elementary particles help us understand the specifics about atoms, and without them there would be no standard model. They are rather interesting too: they are found in animals; found in food; found in space. They keep us both alive, and are responsible for many phenomenons. Elementary particles are important to us because they help make up atoms, include the important force carriers, and open up new thoughts and ideas on different topics, like quantum physics.
We stand at the base of a new age. We are just now beginning to learn the intricate details of life, both macroscopic and microscopic. Ultimately these discoveries will benefit all of mankind. Never before have we enjoyed such a golden age for science and discovery. The scientific horizon looks fruitful. One such fruit is the discovery and application of a thing called antimatter. During the next few decades our ability to produce, accumulate, and contain large quantities of antimatter should become feasible, leaving us just to research possible uses for this promising, radically new, form of energy.
“Sheltered as we are by Earth's atmosphere and magnetic field, which deflect lethal radiation from space, we are like coddled children who have never ventured into a tough neighborhood” (Folger 2). Humans have been fascinated with space since the beginning of our time. Just like children and rough neighborhoods, we have tackled obstacle over obstacle to make it home again. In the end, we have a better knowledge and strength than before. The future of space exploration can assist us in answering the everlasting question of how the universe came to be. The more we explore the infinite galaxies, the more we can scientifically discover and create new technologies as science advances. As we continue to discover, we can create new fields and occupations for aspiring young students like myself.
Gravity keeps our feet on the ground and it keeps us from jumping into space; it sends apples to fall on Isaac Newton’s head, and even though gravity is responsible for keeping the planets in their orbit, gravity still only plays a very small part at the atomic and quantum level.
