For thousands of years man has sought to further his understanding of the world in which he lives. This has been accomplished through research and experimentation all in the name of science. These advancements in science have given us a better understanding of our universe by allowing us to look both at the bigger picture and the smaller picture. Research that has led to the discovery of protons and neutrons has allowed us to realize that there is an even smaller particle that makes these infinitely tiny particles; that particle is the quark.
A Quark is a type of subatomic particle that is currently the smallest form of matter in the known universe. These particles are what make up both neutrons and protons. Neutrons and protons are made of three quarks put together. Quarks are also used to build mesons. Mesons are built when a quark and antiquark are bonded by a strong force. In total there are six different types of quarks. They each have varying masses and charges. Each quark type is paired with another type of quark. The different types of quarks are up, down, charm, strange, top, and bottom. Quarks are also known to have no smaller particles within them and are used to form all hadrons. Quarks and leptons together make atoms and are both the most basic forms of matter. Quarks make the protons and neutrons while electrons are a type of lepton. Quarks all have a fraction of a positive charge while leptons either have a whole negative charge or no charge at all depending on the type of lepton.
Quarks are important particles because of they make up most of the matter on the Earth. Quarks are the smallest pieces of matter that we know about so far and are crucial in helping understand more about ourselves and the world we live ...

... understanding of quarks are the better our understanding of the things they make will be. This includes our understanding of nuclear reactions, harvesting energy, and understanding characteristics of matter. The better we know quarks and other subatomic particles the easier it will be to predict the outcomes of certain scenarios.
Quarks have become important pieces of matter that have allowed us to further our knowledge of what everything is made of. Quarks are the smallest objects in the universe and they along with leptons make up all pieces of matter. Research done on quarks has allowed us to better understand the particles they form. As research continues in quarks one can only imagine the possibilities for further research that can be done based off of our knowledge of quarks. Our knowledge of quarks may very well be the key to understanding our universe.
The Standard Model is known as a gauge theory, and is based on the symmetry group SU(3)C⊗SU(2)L⊗U(1)Y; as described in the previous section the symmetry group of standard model, describes the strong, weak and electromagnetic interactions, via the exchange of 8 massless gluons and 1 massless photon, respectively, for the strong and electromagnetic interactions, and three massive bosons, W± and Z, for the weak interaction2. Leptons and quarks which are the building blocks of the fermionic matter, are characterized in the structure below,
have played an important part in the scientific world by putting forth their discoveries for
...e and the nature of things to help us to connect ourselves to stories of the past and present while trying to do exactly what Petrus Camper and the scholars of the eighteenth-century were so capable of—the same privilege the wave-particle theory gave to the pioneers of quantum mechanics: to understand the multiverse of intellectual disciplines together.
However, unlike QED, the reactions of quarks caused by the strong nuclear force are confined to within the particle composed of those quarks (TOE, 21st Century Science) (QFT, Britannica School). The weak nuclear force, though possessing a theory called quantum flavordynamics, with force carriers named the W and Z particles, is now usually combined with electromagnetism to form the electroweak force (Electroweak force, Britannica
For centuries, physicists and philosophers alike have wondered what makes up our universe. Aristotle thought that all matter came in one of four forms: Earth, Air, Fire, and Water. Since then we have come a long way, with the discovery of the atoms and the subatomic particles they are made of. We can even guess at what makes up protons and neutrons. We have since then discovered and predicted the existence of particles other than the atom, such as the photon, neutrino, axion, and many others.
That was until 1974 when two discoveries occurred at the Brookhaven Laboratory and Stanford. They had found a new particle. Stanford called it the psi and Brookhaven called it the J. The new particle had to be a new kind of quark. Two years later Harvard theorist Sheldon Glashow named the new particle the charmed quark. This discovery shattered any doubts about the quark being real or not.
Quantum Mechanics is a branch of physics that describes the structure and behavior of matter.
An atom, by definition, is the smallest part of any substance. The atom has three main components that make it up: protons, neutrons, and electrons. The protons and neutrons are within the nucleus in the center of the atom. The electrons revolve around the nucleus in many orbitals. These orbitals consist of many different shapes, including circular, spiral, and many others. Protons are positively charged and electrons are negatively charged. Protons and electrons both have charge of equal magnitude (i.e. 1.602x10-19 coulombs). Neutrons have a neutral charge, and they, along with protons, are the majority of mass in an atom. Electron mass, though, is negligible. When an atom has a neutral charge, it is stable.
Polkinghorne asserts that “scientists are motivated by the desire understand what is happening in the world.”(551, Polkinghorne). As a physicist himself, Polkinghorne understands the desire to understand the world, even shifting careers to become a priest to better his understanding. Science asks how things happen, and does not attempt to answer every question. Questions asking why go ignored, as if they are not necessary to fully understand the world and the life that lives here. Science alone
In 1803 this theory was finalised and stated that (1) all matter is made up of the smallest possible particles termed atoms, (2) atoms of a given element have unique characteristics and weight, and (3) three types of atoms exist: simple (elements), compound (simple molecules), and complex (complex molecules).
Moseley's research starts of the chapter with his discovery of the proton, and how an element with more protons has a bigger mass making it necessary for it to come after a element with a weaker charge. with a weaker charge. When describing Moseley’s research and why a proton is significant, Sam includes how “electrons are attracted to an atom’s nucleus because electrons and protons have opposite charges”(99). The background knowledge included helps clarify the significance of the the discovery and why it make sense for element to be arranged based on weight. Mosley's decision of joining the army is significant and include by Sam to show what was need to motivate scientist to discover new elements. The death of moseley s significant due to “the best tribute scientist could pay Moseley was to hunt down all the missing elements”(102). New elements being discovered would only live for seconds due to them being unstable and later decay into (a new discovery as a result of element hunting) “a new element [the most] dramatic change on a nuclear level”(105). During this passage Sam uses unbiased language in order to provide for the most credible information. Moving to the Manhattan Project Sam includes the fact that the method being used was highly dependent on calculations. The people doing the calculations were women mostly “scientist wives due to them being bored
The theory of quantum mechanics has divided the atom into a number of fundamental sub-atomic particles. Although the physicist has shown that the atom is not a solid indivisible object, he has not been able to find a particle which does possess those qualities. Talk of particles, though, is misleading because the word suggests a material object. This is not the intention for the use of the word in quantum physics. Quantum particles are, instead, representations of the actions and reactions of forces at the sub-atomic level. In fact, physicists are less concerned with the search for a material particle underlying all physical objects and more interested in explaining how nature works. Quantum theory is the means that enables the physicist to express those explanations in a scientific way.
Alpha radiation/emission - Alpha particles are the nuclei of a Helium atom 42He. Consisting of two protons and two neutrons, positively charged.
Quarks make up protons and neutrons, while leptons make up electrons. Combinations of these fermions are essentially why we have different elements, since they make up the different particles in atoms. Remember that elements are substances that cannot be broken down into simpler substances, and are primary constituents of matter. They are important, and they exist because of these fermions. This makes the relationship between quarks and leptons extremely important. Take this simple example: why aren’t there any elements made up of just neutrons (quarks)? T...
Antimatter is exactly what the name suggests. It is the opposite of matter in which the charges associated with electrons and protons are switched. This means a proton and antiproton are attracted to each other. When they collide pane energy is produced in the form of three pions and four gamma rays.
