Model theory
In mathematics, model theory is the study of classes of mathematical structures (e.g. groups, fields, graphs, universes of set theory) from the perspective of mathematical logic. The objects of study are models of theories in a formal language. We call a set of sentences in a formal language a theory; a model of a theory is a structure (e.g. an interpretation) that satisfies the sentences of that theory.
Model theory recognises and is intimately concerned with a duality: It examines semantical elements (meaning and truth) by means of syntactical elements (formulas and proofs) of a corresponding language. To quote the first page of Chang & Keisler (1990):
Model theory developed rapidly during the 1990s, and a more modern definition is provided by Wilfrid Hodges (1997):
although model theorists are also interested in the study of fields. Other nearby areas of mathematics include combinatorics, number theory, arithmetic dynamics, analytic functions, and non-standard analysis.
In a similar way to proof theory, model theory is situated in an area of interdisciplinarity among mathematics, philosophy, and computer science. The most prominent professional organization in the field of model theory is the Association for Symbolic Logic.

Inner model theory
In set theory, inner model theory is the study of certain models of ZFC or some fragment or strengthening thereof. Ordinarily these models are transitive subsets or subclasses of the von Neumann universe V, or sometimes of a generic extension of V. Inner model theory studies the relationships of these models to determinacy, large cardinals, and descriptive set theory. Despite the name, it is considered more a branch of set theory than of model theory.

What’s the difference between a scientific law and theory? - Matt Anticole
View full lesson: http://ed.ted.com/lessons/what-s-the-difference-between-a-scientific-law-and-theory-matt-anticole Chat with a friend about an established scientific theory, and she might reply, “Well, that’s just a theory.” But a conversation about an established scientific law rarely ends with “Well, that’s just a law.” Why is that? What is the difference between a theory and a law... and is one “better”? Matt Anticole shows why science needs both laws and theories to understand the whole picture.

The holy grail of physics research is a theory of everything. But we already have a pretty good model for such a theory. It is the Standard model of particle physics. It describes all fundamental particles that we are aware of, and three of the 4 known fundamental forces, electromagnetism, strong, and weak interactions. It just doesn’t include gravity.
The simple equation and chart actually represents very complex mathematical equations that can take years of graduate level study to fully understand. It was developed by hundreds of scientists over several decades. In this video, I explain the math intuitively.
0:00 - The best known theory
2:00 - The Standard Model explained
4:05 - What is a Lagrangian
5:01 - How forces interact
6:52 - How matter interacts with forces
9:32 - Higgs-boson interactions
11:25 - Higgs-matter interactions
13:23 - Summary
Ordinary matter that we experience around us is really just made of 4 particles, the up and down quarks which make up the protons and neutrons in the nuclei of atoms, electrons which form a cloud around the nucleus, and a near massless particle - the electron neutrino which is created during the fusion process in stars like the sun. The other particles are rare and don’t typically exist in ordinary matter.
The difference between quarks and leptons is that quarks interact with the strong nuclear force which binds the nuclei of atoms together, whereas leptons do not. The Bosons are the force carriers. The gluons carry the strong force which binds the nuclei of atoms. The W plus, W minus and Z boson carry the weak force which is responsible for some kinds of radiation. And the photons carry the electromagnetic force responsible for all electricity, magnetism and chemistry.
Lastly, we have the Higgs boson which is important for giving mass to all fundamental particles.
A Lagrangian is just like the sum of all energies. The entire universe can be represented by the mathematics that accounts for energy. The standard model is a quantum field theory. This means that particles are an excitation in a quantum field. It is not like a tiny marble. It is like tiny waves.
The first term is composed of two matrices F sub mu nu, and F superscript mu nu. This term represents all the ways that all the force carrying particles, the bosons interact with each other. Only the Higgs in not included in this term.
The next term in the simple Lagrangian refers to the fermion fields and their interaction with the gauge fields. Simply put, it describes how matter interacts with forces. There is a factor i in these terms. This is the imaginary number defined as the square root of minus one. It is a mathematical tool that allow the use of more numbers so we are not constrained to only the simple real numbers. This is allowed in physics as long as your final result representing physical values does not contain it.
Particles have a property where they are either right-handed or left-handed. Right handed means that the spin of the particle is in the same direction as the motion of the particle. Left handed means that the spin is in the opposite direction of motion. This is important for leptons because it turns out that only left-handed neutrinos exist. But, electrons and its heavier cousins the Muon and Tau particle, can be both left or right-handed.
The next two terms describe how the force-carrying particles interact with the Higgs field and how the Higgs interacts with itself. Higgs is the only field in the standard model that has a potential. The potential is what is responsible for giving mass.
The subscripts R and L, again refer to the left and right-handed particles. The Y (gamma) represents the Yukawa couplings of each particle to the Higgs field – The stronger the coupling, the higher the mass that the particle acquires.
Finally, the last term is this h.c. terms and that just means Hermitian conjugate. While the prior term describes the interaction between a Higgs particle and matter particles, this describes the same interaction with antimatter particles. We have to take the antimatter particles into account in this Lagrangian because they also exist.
This equation is describes what almost all the universe it made of, as we understand it. The first term is how all the quantum forces of the universe interact with each other. The second term is how matter interacts with all the forces. The third term is how force particles gain mass. The fourth term is how the Higgs interacts with itself. The fifth and sixth terms describe are how the matter and antimatter particles gain mass.

Although this is the best and closest thing we have to a theory of everything, it has some gaps, gravity, dark matter and Dark energy is not in this model. So there is plenty of work to be done.

Will A New Neutrino Change The Standard Model?
https://www.youtube.com/watch?v=0mXW1zPlxEE&t
As far as we can tell, mathematics is the language in which the universe is written. Our laws of physics are equations of motion, along with some associated constants. Previously we’ve talked a bit about the symmetries of these equations, and how they lead us to conserved quantities. But this is just the tip of the theoretical iceberg - sometimes investigating the symmetries of these equations predicts entirely new physics. The most remarkable example of this is the standard model of particle physics. You know, the most accurate physical theory in all of human history.

Chat with a friend about an established scientific theory, and she might reply, “Well, that’s just a theory.” But a conversation about an established scientific law rarely ends with “Well, that’s just a law.” Why is that? What is the difference between a theory and a law... and is one “better”? Matt Anticole shows why science needs both laws and theories to understand the whole picture.

The holy grail of physics research is a theory of everything. But we already have a pretty good model for such a theory. It is the Standard model of particle physics. It describes all fundamental particles that we are aware of, and three of the 4 known fundamental forces, electromagnetism, strong, and weak interactions. It just doesn’t include gravity.
The simple equation and chart actually represents very complex mathematical equations that can take years of graduate level study to fully understand. It was developed by hundreds of scientists over several decades. In this video, I explain the math intuitively.
0:00 - The best known theory
2:00 - The Standard Model explained
4:05 - What is a Lagrangian
5:01 - How forces interact
6:52 - How matter interacts with forces
9:32 - Higgs-boson interactions
11:25 - Higgs-matter interactions
13:23 - Summary
Ordinary matter that we experience around us is really just made of 4 particles, the up and down quarks which make up the protons and neutrons in the nuclei of atoms, electrons which form a cloud around the nucleus, and a near massless particle - the electron neutrino which is created during the fusion process in stars like the sun. The other particles are rare and don’t typically exist in ordinary matter.
The difference between quarks and leptons is that quarks interact with the strong nuclear force which binds the nuclei of atoms together, whereas leptons do not. The Bosons are the force carriers. The gluons carry the strong force which binds the nuclei of atoms. The W plus, W minus and Z boson carry the weak force which is responsible for some kinds of radiation. And the photons carry the electromagnetic force responsible for all electricity, magnetism and chemistry.
Lastly, we have the Higgs boson which is important for giving mass to all fundamental particles.
A Lagrangian is just like the sum of all energies. The entire universe can be represented by the mathematics that accounts for energy. The standard model is a quantum field theory. This means that particles are an excitation in a quantum field. It is not like a tiny marble. It is like tiny waves.
The first term is composed of two matrices F sub mu nu, and F superscript mu nu. This term represents all the ways that all the force carrying particles, the bosons interact with each other. Only the Higgs in not included in this term.
The next term in the simple Lagrangian refers to the fermion fields and their interaction with the gauge fields. Simply put, it describes how matter interacts with forces. There is a factor i in these terms. This is the imaginary number defined as the square root of minus one. It is a mathematical tool that allow the use of more numbers so we are not constrained to only the simple real numbers. This is allowed in physics as long as your final result representing physical values does not contain it.
Particles have a property where they are either right-handed or left-handed. Right handed means that the spin of the particle is in the same direction as the motion of the particle. Left handed means that the spin is in the opposite direction of motion. This is important for leptons because it turns out that only left-handed neutrinos exist. But, electrons and its heavier cousins the Muon and Tau particle, can be both left or right-handed.
The next two terms describe how the force-carrying particles interact with the Higgs field and how the Higgs interacts with itself. Higgs is the only field in the standard model that has a potential. The potential is what is responsible for giving mass.
The subscripts R and L, again refer to the left and right-handed particles. The Y (gamma) represents the Yukawa couplings of each particle to the Higgs field – The stronger the coupling, the higher the mass that the particle acquires.
Finally, the last term is this h.c. terms and that just means Hermitian conjugate. While the prior term describes the interaction between a Higgs particle and matter particles, this describes the same interaction with antimatter particles. We have to take the antimatter particles into account in this Lagrangian because they also exist.
This equation is describes what almost all the universe it made of, as we understand it. The first term is how all the quantum forces of the universe interact with each other. The second term is how matter interacts with all the forces. The third term is how force particles gain mass. The fourth term is how the Higgs interacts with itself. The fifth and sixth terms describe are how the matter and antimatter particles gain mass.

#standardmodellagrangian
#theoryofeverything
Although this is the best and closest thing we have to a theory of everything, it has some gaps, gravity, dark matter and Dark energy is not in this model. So there is plenty of work to be done.

In simple terms a gauge theory is one that has mathematical parameters, or “degrees of freedom” that can be changed without affecting the predictions of the theory.

As far as we can tell, mathematics is the language in which the universe is written. Our laws of physics are equations of motion, along with some associated constants. Previously we’ve talked a bit about the symmetries of these equations, and how they lead us to conserved quantities. But this is just the tip of the theoretical iceberg - sometimes investigating the symmetries of these equations predicts entirely new physics. The most remarkable example of this is the standard model of particle physics. You know, the most accurate physical theory in all of human history.

Chat with a friend about an established scientific theory, and she might reply, “Well, that’s just a theory.” But a conversation about an established scientific law rarely ends with “Well, that’s just a law.” Why is that? What is the difference between a theory and a law... and is one “better”? Matt Anticole shows why science needs both laws and theories to understand the whole picture.

Model theory
In mathematics, model theory is the study of classes of mathematical structures (e.g. groups, fields, graphs, universes of set theory) from the perspective of mathematical logic. The objects of study are models of theories in a formal language. We call a set of sentences in a formal language a theory; a model of a theory is a structure (e.g. an interpretation) that satisfies the sentences of that theory.
Model theory recognises and is intimately concerned with a duality: It examines semantical elements (meaning and truth) by means of syntactical elements (formulas and proofs) of a corresponding language. To quote the first page of Chang & Keisler (1990):
Model theory developed rapidly during the 1990s, and a more modern definition is provided by Wilfrid Hodges (1997):
although model theorists are also interested in the study of fields. Other nearby areas of mathematics include combinatorics, number theory, arithmetic dynamics, analytic functions, and non-standard analysis.
In a similar way to proof theory, model theory is situated in an area of interdisciplinarity among mathematics, philosophy, and computer science. The most prominent professional organization in the field of model theory is the Association for Symbolic Logic.
