  • Particulate Matter Essay

    yet to understand why there was a surplus of matter during the big bang and not all matter was annihilated along with antimatter. A quark is a fundamental constituent of matter and they are the building blocks of hadrons. Theories suggest that there are 6 different levels of quarks and in 1995 physicists at Fermilab announced the discovery of the top quark. They were able to see that this quark was heavier than a gold atom but much smaller than a proton. They did this using the world’s highest particle accelerator, the Tevatron. On February 24th 1999, physicists at Fermilab announced results establishing the existence of direct CP violation in the decay of kaon (particles containing a strange quark), which is a significant step in understanding why there was a surplus of matter during the big-bang. On July 21st 2000, Fermilab then announced the first direct evidence to the proof of the tau neutrino, the third kind of neutrino known in particle physics. Nobody had previously observed the interaction of the tau neutrino with matter because they are barely massless and do not Interact with any surrounding matter. The massive developments in technology have allowed physicists to be able to closely study antimatter and particulate matter in much detail, leading to a stronger understanding of the universe. Fermilab continue to research different quarks and study the universe to develop a further understanding and discover things that human imagination cannot think. Cosmic Rays…

  • Love And Determination In Janie's The Face On The Milk Carton

    The Truth Janie never gives up on what she believes in and her family stands by her through it all and supports her with love. Janie did not let what anyone say get in the way of what she thought was right. Love and determination is apparent three times in the book The Face on The Milk Carton. The first time determination is illustrated is when Janie kept searching for answers and did not give up on finding out her past or else she would have never found out the truth. The second time…

  • Essay On Cosmological Argument

    I believe that “The Cosmological Argument” for God is still quite valid, my reasons for defending this argument have been produced after a great deal of reflection on the matter, I have concluded that the argument is still quite useful. To best describe the argument, it is the conclusion that “nothing comes from nothing” as was stated by St. Aquinas, in other words God must exist because if there was nothing then we needed something to “call it into existence” so to speak. This coincides…

  • Science: The Atomic Theory

    arranged on the periodic table. By count of their valence electrons on their outer orbital, and also by which orbital the valence electrons are located. You can see this by seeing that the valence electrons are the only consistent variable in the groups rather than their Atomic Number, tells you the number of protons in the atom, and the Mass Number which is the mass of the atom by calculating how many protons and neutrons are in the atom. Until recently we also believed that protons and…

  • The Five Major Components Of The Atomic Theory

    nuclear force.The Planetary Model, which is an illustration of an atom drawn by Niels Bohr demonstrates what the atom looks like. Neutrons have a neutral charge, meaning they do not have a positive or negative charge. The number of protons and electrons in the nucleus is the same number. Protons and neutrons, which put together with electrons make up an atom, are made up of even smaller particles called quarks. There are six quarks, but usually scientists refer to them in three pairs. The six…

  • The Atomic Theory

    named quarks, and the quark theory has been around since approximately the mid-1960’s. There are three types, or flavors, of quarks. They come in pairs and are known as: top and bottom, charm and strange, and up and down. In the Modern Atom Model, it is noted that quarks jiggle within protons and neutrons, which jiggle in the nucleus. It is also noted that electrons are in constant motion around the nucleus. However, these particles have never been seen. But, scientists have collected data…

  • Atomic Theory Essay

    Erwin Schrödinger was the one who proposed the cloud model in 1925. He just added on to what Bohr was already working on. Erwin developed the probability function for the hydrogen atom. Heisenburg is another name that was involved with the atomic theory. Werner Heisenburg studied the behaviors of the electrons, movements into electrons, and quantum theory. The quantum theory is a part of today’s generation. It’s used in some of the objects that we use such as; MRI’s, CD’s, DVD’s, LED lights…

  • Atomic Particles In Research

    An atom is known as the basic unit of a chemical element; however, atoms are no longer considered the smallest particle in existence. From approximately 460 BC to present day 2015, human knowledge about atomic particles has drastically changed. Over the years, research has led to new discoveries involving atoms, subatomic particles, and quarks. Several philosophers including Leucippus, Democritus, Dalton, Thomson, Rutherford, and Gell-Mann have contributed to humanity 's vast knowledge about…

  • Why Is The Atomic Theory Important

    In an atom a nucleus is surrounded by electrons that are in constant motion.The electrons are in electron clouds, or where they go in the atom. The proton, p+ and neutrons jiggle in the nucleus and quarks are jiggling within them. Electron orbits have different sub-levels, the s,p,d, and f orbitals. The strange quark is the third lightest of all quarks. The top quark is the truth quark and is a fundamental constituent of matter, a corpuscle is also like this but deals with light. The opposite…
