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 how it works. The simple definition of a particle is that it is a tiny part of matter. While not incorrect, this answer lacks complexity. As we said before, particles make up everything; but they also constitute 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 up of individual particles called quarks. A quark is one of a group of subatomic particles that are fundamental constituents. (abyss.uoregon.edu) More than two hundred subatomic particles have been detected by the super collider, but not all of them are fundamental, meaning 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 constitute the most basic and smallest unit of matter 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, everyday matter is the first that is already understood, which is why scientists often choose to focus on up and down quarks, the electronic neutral.. .... middle of paper .... .... participates in the change of flavor of quarks, its interactions are therefore more difficult to detect. It interacts by influencing the neutrino scattering cross sections in what are called “neutral currents”. W and Z particles are also involved in the beta decay process, which results in the formation of beta particles. (Hyper physics: expar)The universe is made up of about two hundred different types of particles that we can't even see with the naked eye. All things are made up of tiny subatomic particles that are always working to make the world go round. It's amazing that this world is made up of such tiny particles, but it's even more amazing that it's made up of only 200 different types. This is what has been discovered, but there could be more. Like all scientific discoveries, there is still more to learn, more to understand and more to discover..
