Generation (particle physics)
In particle physics, a generation (or family) is a division of the elementary particles. Between generations, particles differ by their (flavour) quantum number and mass, but their interactions are identical.
There are three generations according to the Standard Model of particle physics. Each generation is divided into two types of leptons and two types of quarks. The two leptons may be classified into one with electric charge −1 (electron-like) and one neutral (neutrino); the two quarks may be classified into one with charge −1⁄3 (down-type) and one with charge +2⁄3 (up-type).
Overview
Each member of a higher generation has greater mass than the corresponding particle of the previous generation, with the possible exception of the neutrinos (whose small but non-zero masses have not been accurately determined). For example, the first-generation electron has a mass of only 6999511000000000000♠0.511 MeV/c2, the second-generation muon has a mass of 7002106000000000000♠106 MeV/c2, and the third-generation tau has a mass of 7003177700000000000♠1777 MeV/c2 (almost twice as heavy as a proton). This mass hierarchy causes particles of higher generations to decay to the first generation, which explains why everyday matter (atoms) is made of particles from the first generation. Electrons surround a nucleus made of protons and neutrons, which contain up and down quarks. The second and third generations of charged particles do not occur in normal matter and are only seen in extremely high-energy environments such as cosmic rays or particle accelerators. The term generation was first introduced by Haim Harari in Les Houches Summer School, 1976.

Particle physics
Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter (particles with mass) and radiation (massless particles). Although the word "particle" can refer to various types of very small objects (e.g. protons, gas particles, or even household dust), "particle physics" usually investigates the irreducibly smallest detectable particles and the irreducibly fundamental force fields necessary to explain them. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. Thus, modern particle physics generally investigates the Standard Model and its various possible extensions, e.g. to the newest "known" particle, the Higgs boson, or even to the oldest known force field, gravity.
Subatomic particles
Modern particle physics research is focused on subatomic particles, including atomic constituents such as electrons, protons, and neutrons (protons and neutrons are composite particles called baryons, made of quarks), produced by radioactive and scattering processes, such as photons, neutrinos, and muons, as well as a wide range of exotic particles. Dynamics of particles is also governed by quantum mechanics; they exhibit wave–particle duality, displaying particle-like behaviour under certain experimental conditions and wave-like behaviour in others. In more technical terms, they are described by quantum state vectors in a Hilbert space, which is also treated in quantum field theory. Following the convention of particle physicists, the term elementary particles is applied to those particles that are, according to current understanding, presumed to be indivisible and not composed of other particles.

Particle
A particle is a minute fragment or quantity of matter. In the physical sciences, the word is used to describe a small localized object to which can be ascribed several physical or chemical properties such as volume or mass; subatomic particles such as protons or neutrons; and other elementary particles. The word is rather general in meaning, and is refined as needed by various scientific fields. Something that is composed of particles may be referred to as being particulate. However, the term particulate is most frequently used to refer to pollutants in the Earth's atmosphere, which are a suspension of unconnected particles, rather than a connected particle aggregation.
Conceptual properties
The concept of particles is particularly useful when modelling nature, as the full treatment of many phenomena is complex. It can be used to make simplifying assumptions concerning the processes involved. Francis Sears and Mark Zemansky, in University Physics, give the example of calculating the landing location and speed of a baseball thrown in the air. They gradually strip the baseball of most of its properties, by first idealizing it as a rigid smooth sphere, then by neglecting rotation, buoyancy and friction, ultimately reducing the problem to the ballistics of a classical point particle. The treatment of large numbers of particles is the realm of statistical physics.

Generation (1960s TV series)
Generation was a Canadian current affairs television series which aired on CBC Television in 1965.
Premise
The series examined contemporary topics and concerns in the context of the generation gap. Issues such as careers, marriage, Quebec's Quiet Revolution, religion or tobacco were the subject of various episodes.
For most of its run, Generation was a local Toronto programme hosted by Lloyd Robertson. In mid-1965, it was broadcast nationally with selected local episodes supplemented by episodes produced from various regions. June Callwood, Katie Johnson and Bill McVean were additional hosts during the national broadcasts.
Scheduling
The half-hour series aired locally on CBLT from late 1963 until mid-1966. It was broadcast on the national CBC network Wednesdays at 10:30 p.m. (Eastern) from 4 August to 15 September 1965.

1837 generation
The 1837 generation (Spanish: Generación del '37) was an Argentine literary group. Influenced by the new romantic ideas, they rejected the cultural Spanish heritage of the country. They considered themselves the "sons of the May Revolution", as they were born shortly after it, and wrote some of the earliest Argentine literary works. They did not acknowledge any national roots in the indigenous peoples or the period of European colonization, focusing instead on the Revolution as the birth of the country.
The group established a literary hall in 1837, hence the name. Initially, they claimed to be neutral in the Argentine Civil Wars, but in time they wrote works biased against the federal governor Juan Manuel de Rosas (such as El Matadero by Esteban Echeverría or Facundo by Domingo Faustino Sarmiento) and became fully Unitarians.
Some notable members of this generation were Esteban Echeverría, Juan Bautista Alberdi, Miguel Cané, Bartolomé Mitre, Andrés Lamas, Antonio Somellera, Vicente Fidel López, Carlos Tejedor, Juan Bautista Peña, Florencio Varela, Juan Cruz Varela, José Mármol, José Rivera Indarte (Buenos Aires), Domingo Faustino Sarmiento, Quiroga Rosas, Antonino Aberastain, Santiago Cortínez (San Juan), Benjamín Villafañe, Félix Frías (Tucumán), Francisco Álvarez, Paulino Paz, Enrique Rodríguez, Avelino Ferreyra, Ramón Ferreyra (Córdoba), Juan Thompson (Corrientes).

Immigrant generations
The term first-generation can refer to either people who were born in one country and relocated to another at a young age, or to their children born in the country they have relocated to. The term second-generation refers to children of first-generation immigrants, and thus exhibits the same ambiguity. The term 1.5 generation is a term coined for people who identify as "first generation" who do not meet the definition.
First generation
The term first-generation, as it pertains to a person's nationality or residency in a country, can imply two possible meanings, depending on context:
This ambiguity is captured and corroborated in The Oxford English Dictionary's definition of "generation":
In the United States, among demographers and other social scientists, the term "first generation" is used to refer to foreign-born residents (excluding those born abroad of American parents).

Particle (ecology)
In marine and freshwater ecology, a particle is a small object. Particles can remain in suspension in the ocean or freshwater. However, they eventually settle (rate determined by Stokes' law) and accumulate as sediment. Some can enter the atmosphere through wave action where they can act as cloud condensation nuclei (CCN). Many organisms filter particles out of the water with unique filtration mechanisms (filter feeders). Particles are often associated with high loads of toxins which attach to the surface. As these toxins are passed up the food chain they accumulate in fatty tissue and become increasingly concentrated in predators (see bioaccumulation). Very little is known about the dynamics of particles, especially when they are re-suspended by dredging. They can remain floating in the water and drift over long distances. The decomposition of some particles by bacteria consumes a lot of oxygen and can cause the water to become hypoxic.
Particle analysis
Particle levels in water (or air) can be measured with a turbidity meter and analyzed with a particle counter. They can also be scanned with an underwater microscope, such as ecoSCOPE. Collected particles of size 20 - 200 micrometers hovering in the free water in the vicinity of a harbor had the following contaminant levels (table). Many of those contaminants are carcinogenic.

The Standard Model of Particle Physics: A Triumph of Science
The Standard Model of particle physics is the most successful scientific theory of all time. It describes how everything in the universe is made of 12 different types of matter particles, interacting with three forces, all bound together by a rather special particle called the Higgs boson. It’s the pinnacle of 400 years of science and gives the correct answer to hundreds of thousands of experiments. In this explainer, Cambridge University physicist David Tong recreates the model, piece by piece, to provide some intuition for how the fundamental building blocks of our universe fit together. At the end of the video, he also points out what’s missing from the model and what work is left to do in order to complete the Theory of Everything. **Correction: At 13'50", the photon should be includ...

The standard model of particle physics is our fundamental description of the stuff in the universe. It doesn’t answer why anything exists, but does describe what exists and how it behaves, and that’s what we’ll be discovering in this video. We will cover the fermions, which contain the quarks and the leptons, as well as the bosons or force carriers. As well as which of the fundamental forces each of these fundamental particles interact with, along with the Higgs field. We’ll also look at the conservation rules of particle physics, symmetries in physics and the various quantum numbers that rule which particle interactions are valid and which are not.

The standard model of particle physics is our fundamental description of the stuff in the universe. It doesn’t answer why anything exists, but does describe what exists and how it behaves, and that’s what we’ll be discovering in this video. We will cover the fermions, which contain the quarks and the leptons, as well as the bosons or force carriers. As well as which of the fundamental forces each of these fundamental particles interact with, along with the Higgs field. We’ll also look at the conservation rules of particle physics, symmetries in physics and the various quantum numbers that rule which particle interactions are valid and which are not.

12:19 - Strong force
16:53 - Higgs
If we generalize the concept of bosons interacting with particles, we can get all fundamental particle physics. Complex math, but physicist Richard Feynman came up with a simple way to view these interactions - Feynman diagrams.
The 12 fermions are depicted as straight lines with arrows in the diagrams. The arrows represent the “flow” of fermions. No two arrows point towards each other. If time is in the x direction, then fermion arrows going forwards are matter particles, and those going backwards, antimatter particles.
All 6 quarks have color charges. All particles with color charges interact with the strong nuclear force. Quarks also have an electric charge, so they also feel the electromagnetic force.
Leptons can be divided into the electron and its heavier cousins, the muon and tau particles. These all have electric charges but no color charges. Neutrinos do not have a color charge or an electric charge, so they are not affected by the strong and electromagnetic forces.
All fermions carry something called weak isospin. This can be thought of as the “charge” of the weak force. It can be +1/2 or -1/2. All fermions interact with the weak force. But weak isospin can also be -1, 0, and +1 – the W- boson has a weak isospin of -1, W+ has +1, Higgs has -1/2, and Z boson and photons have a weak isospin of 0. Note that this zero is not the same has having no isospin. Everything in the standard model has a weak isospin except gluons.
The weak force has the power to turn one particle into another particle. It is the only force that can do that.
To recap, quarks interact with all forces, electron like particles interact with electromagnetism and the weak force, but do not interact with the strong force. Neutrinos only interact with the weak force and nothing else. Only quarks and gluons carry the strong force. Higgs bosons do not interact with photons or gluons. They confer mass to fundamental particles, so all fundamental particles with mass interact with Higgs.
The simplest force is electromagnetic which interacts with quarks and leptons. Repulsion is depicted in Møller scattering. Attraction is shown in Bhabha scattering. When electrons and positrons are near each other, they can annihilate or attract each other.'
Weak force is felt by all of the standard model particles, except gluons. W-boson can do something very special. They can change the identity or flavor of the particle - a neutron to a proton. We probably would not exist without it.
Z-boson has no electric charge and can mediate interactions with electrically neutral particles like the neutrino and the Higgs.
The strong force is the most complicated mathematically, but since it only relates to quarks and gluons. A pair of quarks can change color. This happens all the time inside protons and neutrons, and is the glue that binds the quarks together.
Because gluons themselves contain color charges, they also interact with each other via complicated diagrams. This is what flux tubes are made of. These tubes are formed when you try to pull quarks apart.
Mesons are formed when a quark tries to leave a nucleon. These mesons are a combination of a quark, anti-quark pairs which mediate the strong force between protons and neutrons.
Pi mesons exchanges colors and quarks between protons and neutron. This is what keeps them glued together. Color charges must be conserved. Either red, blue, and green must combine, or color anti-color must combine to form a neutral color charge.
The most prominent process used at the Large hadron collider to make a Higgs boson is called the gluon fusion process. During high energy proton-proton collisions, two high energy gluons can be produced. Strong force interaction can turn these into top quarks which fuse together via a loop of top quark, anti-top quark creation and annihilation. The energy of this can create a Higgs boson.

What is the Large Hadron Collider used for? How do we know that dark matter exists? Join Pauline Gagnon as she explores these questions and the current ongoing research at CERN, the European Laboratory for Particle Physics. Watch the Q&A here: https://youtu.be/vQ8W6_uM0Pw
Pauline's new book 'Who cares about particle physics?: Making sense of the Higgs Boson, the Large Hadron Collider and CERN' is available now: https://geni.us/duwOL
Subscribe for regular science videos: http://bit.ly/RiSubscRibe
Could we be at the dawn of a huge revolution in our conception of the material world that surrounds us?
The creativity, diversity and motivation of thousands of scientists have gone into CERN, and ensured the success of one of the largest scientific projects ever undertaken. It has led to scientists being able to describe the smallest constituents of matter, and the role of the Higgs boson. This talk explores the world of particle physics, spanning the infinitesimally small to the infinitely large.
This talk was recorded at the Ri on 26 September 2022.
Pauline Gagnon first studied at San Francisco State University then completed a PhD in particle physics at University of California in Santa Cruz. Pauline then started research activities at CERN, the European Laboratory for Particle Physics located near Geneva, where Pauline worked as a Senior Research Scientist with Indiana University until retirement in 2016.

Simulating Particle Life
Particle Life is a fascinating simulation model that showcases emergent behavior arising from simple rules. Inspired by Jeffrey Ventrella's "Clusters" ( ventrella.com/Clusters ). This simulation resembles real-life organisms, demonstrating that emergent behavior doesn’t require complex processes.

10:11 - What does Fundamental mean?
11:22 - What is the best definition of a particle?
Summary:
Ask 10 physicists what a particle is: you'll get 10 different answers. Quantum mechanics showed via the Schrodinger equation, that quantum objects are not particles but waves smeared out in space, until the moment we measure it. They are described by a mathematical term called a wave-function. It doesn’t tell us where a particle is, but only the probability of where it might be if we measured it.
Is a particle a collapsed wave function? Maybe, but this is not a good description because we don’t know what wave function collapse means. Quantum mechanics shows that photons are a wave packet. This wave packet can be looked at as a kind of particle. Something similar can be done for describing other particles too.
The Schrodinger equation does not work when objects travel close to the speed of light. It does not account for special relativity. In the 1930’s scientists like Dirac found a modification that was compatible with special relativity. This led to quantum field theory, or QFT.
In quantum field theory, what we call particles are quantized waves in a field that spreads throughout spacetime. The idea of quantized fields was a necessary step in order to describe objects like photons and other fast moving objects that need to be treated according to special relativity. QFT is nothing but a theoretical framework that unites ideas from classical fields, special relativity and quantum mechanics.
The idea is this: you start with a field or analogously picture yourself a calm sea that stretches throughout all of spacetime. This is an empty field without any particles. Now imagine that there is a wave in the sea, this is a particle in our field. There is however at least one difference between the quantum field and our ocean, our ocean is not quantum.
For our ocean field to be quantum we have two requirements. First, the waves in our sea must have some discrete magnitude. This can be represented by the amplitude or height of the wave, like 1 meter, 2 meters, 3 meters and so on, nothing in between. Each meter corresponds to the number of particles in any one place. The second requirement is that there has to be some minimum energy state at all times. So we will say that the 1-meter waves represent this minimum energy state. This is called the vacuum energy. I
Then each extra meter of amplitude or height is a real particle. We can only create taller waves in increments of whole meters. The minimum aplitude is 1-meter waves. Each extra meter is then a real particle. But we can only create these taller waves if we have enough energy to reach the next meter. If there is not enough energy to reach at least 2 meters, no taller wave is created.
These one meter waves are from the quantum vacuum, they represent the non-empty minimal state. These quantum waves slosh around and, in some places, there might momentarily be enough energy to create a larger 2-meter wave or a particle. But then almost just as quickly as it’s formed, the particle vanishes again in the sea of fluctuations. These are analogous to virtual particles that come in and out of existence all around us, but are undetectable because they last for too short a time.
The quantum field is like the sea – it is the background on which waves appear and disappear. And just like energy can create waves in the sea, energy added to the field generates particles which we can observe.
If you expand this concept to other particles, we have to imagine other seas representing a different field for each fundamental particle that we know of, so there would be a sea representing the field for electrons, field for photons, field for quarks, etc.
What does “fundamental” in the word fundamental particles mean? It means that the particles of the standard model are the smallest particles from which we can construct the world around us. There is nothing, that we know of that is smaller that these fundamental particles are made of.
#quantumfieldtheory
#qft
As of now, the best description for a particle would be something like this:
A fundamental particle is an excitation in a quantum field that is constantly in flux. There are at least as many fields as there are particles in the standard model. Each particle can propagate in its field. The interactions of these fields and exchange of energy results in particle creation and annihilation. In the end, you should remember that this is just all math.

Can you really send a particle into the past? New Scientist published an article about this last week, and though I’m quite fond of the concept of retrocausality, I’m afraid to say that reality is much less interesting than fiction. Let’s have a look.

The Standard Model of particle physics is the most successful scientific theory of all time. It describes how everything in the universe is made of 12 different types of matter particles, interacting with three forces, all bound together by a rather special particle called the Higgs boson. It’s the pinnacle of 400 years of science and gives the correct answer to hundreds of thousands of experiments. In this explainer, Cambridge University physicist David Tong recreates the model, piece by piece, to provide some intuition for how the fundamental building blocks of our universe fit together. At the end of the video, he also points out what’s missing from the model and what work is left to do in order to complete the Theory of Everything.
**Correction: At 13'50", the photon should be included with the three fundamental forces. The animation here is incorrect, while the narration is correct.

The standard model of particle physics is our fundamental description of the stuff in the universe. It doesn’t answer why anything exists, but does describe what exists and how it behaves, and that’s what we’ll be discovering in this video. We will cover the fermions, which contain the quarks and the leptons, as well as the bosons or force carriers. As well as which of the fundamental forces each of these fundamental particles interact with, along with the Higgs field. We’ll also look at the conservation rules of particle physics, symmetries in physics and the various quantum numbers that rule which particle interactions are valid and which are not.

If we generalize the concept of bosons interacting with particles, we can get all fundamental particle physics. Complex math, but physicist Richard Feynman came up with a simple way to view these interactions - Feynman diagrams.
The 12 fermions are depicted as straight lines with arrows in the diagrams. The arrows represent the “flow” of fermions. No two arrows point towards each other. If time is in the x direction, then fermion arrows going forwards are matter particles, and those going backwards, antimatter particles.
All 6 quarks have color charges. All particles with color charges interact with the strong nuclear force. Quarks also have an electric charge, so they also feel the electromagnetic force.
Leptons can be divided into the electron and its heavier cousins, the muon and tau particles. These all have electric charges but no color charges. Neutrinos do not have a color charge or an electric charge, so they are not affected by the strong and electromagnetic forces.
All fermions carry something called weak isospin. This can be thought of as the “charge” of the weak force. It can be +1/2 or -1/2. All fermions interact with the weak force. But weak isospin can also be -1, 0, and +1 – the W- boson has a weak isospin of -1, W+ has +1, Higgs has -1/2, and Z boson and photons have a weak isospin of 0. Note that this zero is not the same has having no isospin. Everything in the standard model has a weak isospin except gluons.
The weak force has the power to turn one particle into another particle. It is the only force that can do that.
To recap, quarks interact with all forces, electron like particles interact with electromagnetism and the weak force, but do not interact with the strong force. Neutrinos only interact with the weak force and nothing else. Only quarks and gluons carry the strong force. Higgs bosons do not interact with photons or gluons. They confer mass to fundamental particles, so all fundamental particles with mass interact with Higgs.
The simplest force is electromagnetic which interacts with quarks and leptons. Repulsion is depicted in Møller scattering. Attraction is shown in Bhabha scattering. When electrons and positrons are near each other, they can annihilate or attract each other.'
Weak force is felt by all of the standard model particles, except gluons. W-boson can do something very special. They can change the identity or flavor of the particle - a neutron to a proton. We probably would not exist without it.
Z-boson has no electric charge and can mediate interactions with electrically neutral particles like the neutrino and the Higgs.
The strong force is the most complicated mathematically, but since it only relates to quarks and gluons. A pair of quarks can change color. This happens all the time inside protons and neutrons, and is the glue that binds the quarks together.
Because gluons themselves contain color charges, they also interact with each other via complicated diagrams. This is what flux tubes are made of. These tubes are formed when you try to pull quarks apart.
Mesons are formed when a quark tries to leave a nucleon. These mesons are a combination of a quark, anti-quark pairs which mediate the strong force between protons and neutrons.
Pi mesons exchanges colors and quarks between protons and neutron. This is what keeps them glued together. Color charges must be conserved. Either red, blue, and green must combine, or color anti-color must combine to form a neutral color charge.
The most prominent process used at the Large hadron collider to make a Higgs boson is called the gluon fusion process. During high energy proton-proton collisions, two high energy gluons can be produced. Strong force interaction can turn these into top quarks which fuse together via a loop of top quark, anti-top quark creation and annihilation. The energy of this can create a Higgs boson.

Could we be at the dawn of a huge revolution in our conception of the material world that surrounds us?
The creativity, diversity and motivation of thousands of scientists have gone into CERN, and ensured the success of one of the largest scientific projects ever undertaken. It has led to scientists being able to describe the smallest constituents of matter, and the role of the Higgs boson. This talk explores the world of particle physics, spanning the infinitesimally small to the infinitely large.
This talk was recorded at the Ri on 26 September 2022.
Pauline Gagnon first studied at San Francisco State University then completed a PhD in particle physics at University of California in Santa Cruz. Pauline then started research activities at CERN, the European Laboratory for Particle Physics located near Geneva, where Pauline worked as a Senior Research Scientist with Indiana University until retirement in 2016.

Generation (particle physics)
In particle physics, a generation (or family) is a division of the elementary particles. Between generations, particles differ by their (flavour) quantum number and mass, but their interactions are identical.
There are three generations according to the Standard Model of particle physics. Each generation is divided into two types of leptons and two types of quarks. The two leptons may be classified into one with electric charge −1 (electron-like) and one neutral (neutrino); the two quarks may be classified into one with charge −1⁄3 (down-type) and one with charge +2⁄3 (up-type).
Overview
Each member of a higher generation has greater mass than the corresponding particle of the previous generation, with the possible exception of the neutrinos (whose small but non-zero masses have not been accurately determined). For example, the first-generation electron has a mass of only 6999511000000000000♠0.511 MeV/c2, the second-generation muon has a mass of 7002106000000000000♠106 MeV/c2, and the third-generation tau has a mass of 7003177700000000000♠1777 MeV/c2 (almost twice as heavy as a proton). This mass hierarchy causes particles of higher generations to decay to the first generation, which explains why everyday matter (atoms) is made of particles from the first generation. Electrons surround a nucleus made of protons and neutrons, which contain up and down quarks. The second and third generations of charged particles do not occur in normal matter and are only seen in extremely high-energy environments such as cosmic rays or particle accelerators. The term generation was first introduced by Haim Harari in Les Houches Summer School, 1976.

The standard model of particle physics is our fundamental description of the stuff in the universe. It doesn’t answer why anything exists, but does describe what exists and how it behaves, and that’s what we’ll be discovering in this video. We will cover the fermions, which contain the quarks and the leptons, as well as the bosons or force carriers. As well as which of the fundamental forces each of these fundamental particles interact with, along with the Higgs field. We’ll also look at the conservation rules of particle physics, symmetries in physics and the various quantum numbers that rule which particle interactions are valid and which are not.

Summary:
Ask 10 physicists what a particle is: you'll get 10 different answers. Quantum mechanics showed via the Schrodinger equation, that quantum objects are not particles but waves smeared out in space, until the moment we measure it. They are described by a mathematical term called a wave-function. It doesn’t tell us where a particle is, but only the probability of where it might be if we measured it.
Is a particle a collapsed wave function? Maybe, but this is not a good description because we don’t know what wave function collapse means. Quantum mechanics shows that photons are a wave packet. This wave packet can be looked at as a kind of particle. Something similar can be done for describing other particles too.
The Schrodinger equation does not work when objects travel close to the speed of light. It does not account for special relativity. In the 1930’s scientists like Dirac found a modification that was compatible with special relativity. This led to quantum field theory, or QFT.
In quantum field theory, what we call particles are quantized waves in a field that spreads throughout spacetime. The idea of quantized fields was a necessary step in order to describe objects like photons and other fast moving objects that need to be treated according to special relativity. QFT is nothing but a theoretical framework that unites ideas from classical fields, special relativity and quantum mechanics.
The idea is this: you start with a field or analogously picture yourself a calm sea that stretches throughout all of spacetime. This is an empty field without any particles. Now imagine that there is a wave in the sea, this is a particle in our field. There is however at least one difference between the quantum field and our ocean, our ocean is not quantum.
For our ocean field to be quantum we have two requirements. First, the waves in our sea must have some discrete magnitude. This can be represented by the amplitude or height of the wave, like 1 meter, 2 meters, 3 meters and so on, nothing in between. Each meter corresponds to the number of particles in any one place. The second requirement is that there has to be some minimum energy state at all times. So we will say that the 1-meter waves represent this minimum energy state. This is called the vacuum energy. I
Then each extra meter of amplitude or height is a real particle. We can only create taller waves in increments of whole meters. The minimum aplitude is 1-meter waves. Each extra meter is then a real particle. But we can only create these taller waves if we have enough energy to reach the next meter. If there is not enough energy to reach at least 2 meters, no taller wave is created.
These one meter waves are from the quantum vacuum, they represent the non-empty minimal state. These quantum waves slosh around and, in some places, there might momentarily be enough energy to create a larger 2-meter wave or a particle. But then almost just as quickly as it’s formed, the particle vanishes again in the sea of fluctuations. These are analogous to virtual particles that come in and out of existence all around us, but are undetectable because they last for too short a time.
The quantum field is like the sea – it is the background on which waves appear and disappear. And just like energy can create waves in the sea, energy added to the field generates particles which we can observe.
If you expand this concept to other particles, we have to imagine other seas representing a different field for each fundamental particle that we know of, so there would be a sea representing the field for electrons, field for photons, field for quarks, etc.
What does “fundamental” in the word fundamental particles mean? It means that the particles of the standard model are the smallest particles from which we can construct the world around us. There is nothing, that we know of that is smaller that these fundamental particles are made of.
#quantumfieldtheory
#qft
As of now, the best description for a particle would be something like this:
A fundamental particle is an excitation in a quantum field that is constantly in flux. There are at least as many fields as there are particles in the standard model. Each particle can propagate in its field. The interactions of these fields and exchange of energy results in particle creation and annihilation. In the end, you should remember that this is just all math.

Particle Life is a fascinating simulation model that showcases emergent behavior arising from simple rules. Inspired by Jeffrey Ventrella's "Clusters" ( ventrella.com/Clusters ). This simulation resembles real-life organisms, demonstrating that emergent behavior doesn’t require complex processes.
