Particles are a very important part of this world. From the particles that make up all the humans in the world to the particles that make up the clothes we wear. Particles define the world we live in and everything we know about it. From the behavior of particles, scientists can determine many things about the world and the way it works.
The simple definition of a particle is that it is a minute portion of matter. While not incorrect this answer lacks complexity. As was previously stated, particles make up everything; but, they also make up even the most basic form of matter the atom. Protons, neutrons, and electrons are all particles that make up an atom. Protons and neutrons themselves are made of individual particles called quarks. A quark is any of a group of subatomic particles that are among the fundamental constituents. (abyss.uoregon.edu)
There are over two hundred subatomic particles that have been detected by the super collider, but not all of those are fundamental, meaning that they are all the same, have no shape, and cannot be broken down into something smaller. These fundamental particles include electrons, and quarks. These fundamental particles are the most basic and smallest unit of matter that has yet to be discovered by scientists. The two most fundamental particles are quarks and leptons. (Think Quest)
Quarks and Leptons are divided into six flavors that correspond to each generation of matter (red, green blue, anti-red, anti-green, and anti-blue). Quarks and antiquarks have electric charges in units of 1/3 or 2/3. Leptons have charges in units of 1 or 0. Normal every day matter is of the first which is already understood, so scientists often choose to concentrate on the up and down quarks, the electron neutr...

...rticipate in the changing of the flavor of the quarks, so its interactions are harder to detect. It interacts by influencing the scattering cross sections for neutrinos in what is called the “neutral currents”. W and Z particles are also involved in the process of beta decay, which results in the forming of beta particles. (Hyper physics: expar)
The universe is made of approximately two hundred different types of particles that we cannot even see with the naked eye. All things are made of tiny subatomic particles that are always at work to make the world keep turning. It is amazing that this world is made of such tiny particles, but it is even more amazing that it is only made of 200 different types. These are what have been discovered, but more could exist. Just like all scientific discoveries, there is still more to learn, more to understand, and more to discover.
At a spiritual level, the Universe is made up of something even more basic. These basic particles are known as the three subtle basic components (trigunās) namely Sattva, Raja and Tama. In the word triguna, "tri" stands for three and "gunās" stand for subtle-components.
Pierre and Marie hypothesised that radioactive particles cause atoms to break down, then release radiation that forms energy and subatomic particles.
In Mendeleev’s days the atom was considered the most basic particle of matter. What Mendeleev and other chemist determined was the atomic weight of each element. How heavy its atoms were in comparison to an atom of hydrogen. Mendeleev said, “I began to look about and write down the elemen...
There are many different types of sub-atomic particle. They all can be classified down to 3 basic types: Bosons, Fermions, and Hadrons. Of these, Bosons and Fermions are fundimental particles and therefore cannot be broken down any farther.
Sub-atomic particles, known as quarks, electrons, photons, and neutrinos were strewn across expanding space. Equal amounts of matter and antimatter particles began to collide and annihilate each other. Gravity, strong and weak nuclear forces, and electromagnetic forces soon came into play.
When people think of comparison and likeness, they rapidly jump to immediate observations and obvious detections. They fail to perceive the more imperative and subtle attributes. Whether anybody knows it or not, everything that inhabits the world and even the universe is alike in at least one way. All of these substances contain matter. Matter is the physical substance which encompasses everything, from dusty nebulas to the food on one’s dinner plate. It can be described as anything that has mass and takes up space. Within this matter are infinitesimal particles called atoms. So far, they are what scientists believe to be the smallest part of anything and can even be synthesized in labs (Oxlade 7.) The knowledge scientists possess of atoms is huge, in contrast to their microscopic size. In fact, modern day scientists would not have even obtained this knowledge if preceding chemists and physicists did not unveil what was covered. They paved the way to the vast expansion of awareness and allowed the atom to be seen in its true form. However, these impeccable discoveries did not spawn from a single human being, but rather from a chronological timeline of coincidental events.
One of the current questions in physics is whether or not neutrinos have mass and what this mass is. Neutrinos are subatomic particles that have no electrical charge and interact only via the weak nuclear force. They are products of radioactive decay processes, and thus are produced abundantly in our Sun, our atmosphere, and in other astrophysical sources such as supernovae and active galactic nuclei. Millions and millions of them are crossing through the Earth every second, but only very few of them will interact with the Earth. In practice you can say they are invisible. But fortunately we can detect them by building a very large detector and waiting long enough.
The neutrino is an elusive beast possessing neither mass nor charge. The only proof of its existence comes in measuring its recoil effect. In the cold heart of subatomic physics, beyond the protons and neutrons that until recently served as the basic building block of atoms, a wellspring of subnuclear particles have been discovered in recent years. This much-theorized-upon neutrino is one of these particles. Research has discovered three types of neutrinos: the electron neutrino, the tau neutrino, and the muon neutrino. An anti-neutrino particle has also been discovered. All are created as the result of particle decay.
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).
The universe is full of many unknown objects and structures; it has millions of unknown mysteries. Many of these objects are so large it is hard for us to understand the extent of them. The universe is so large that it is hard for humans to even comprehend how big it really is. Everything that is studied in astronomy is so much bigger than any human scale that we work with. Some of the objects in the universe that are have been discovered and are still currently being discovered are the cosmic web, super cluster, voids, Lyman alpha blobs, radio jets, black holes, star and so much more. I watched a film on YouTube to understand more about these objects and this is what I found.
The first real evidence that neutrinos may posses tiny particles of mass where when a giant particle detector was located deep in a mind in Japan. Neutrinos carry no electric charge. This particle-detecting equipment is sensitive only to charted particles, scientists are not able to observe neutrinos directly. If a neutrinos collides with a proton or neutron, the particles in the nucleus of and atom, the neutrino is transformed into a charged particle.
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.
The next big step in the discovery of the atom was the scientific test that proved the existence of the atom. After the discovery of the atom we had the discovery of subatomic particles. With the discovery of the subatomic particles came the research, which came from experiments that were made to find out more about the subatomic particles. This research is how we uncovered that most of the weight of an atom is from its nucleus. With the gold foil experiment, tested by Ernest Rutherford, he discovered the existence of the positively charged nucleus. He proved this when the experiment was happening, a small fraction of the photons th...
Some physical entities such as light can display some characteristics of both particles and waves. Before the early 20th century, scientists believed that light was in the form of an electromagnetic wave. It wasn’t until the 20th century onwards that scientists found that light has properties of waves and particles. Scientists discovered different properties of light through experimentation and allowed them to determine that light actually has a wave-particle duality.
