Hyperbolic lattices and two-dimensional Yang-Mills theory
— Hyperbolic lattices are a new type of synthetic quantum matter emulated in circuit quantum electrodynamics and electric-circuit networks, where particles coherently hop on a discrete tessellation of two-dimensional negatively curved space. While real-space methods and a reciprocal-space hyperbolic band theory have been recently proposed to …
C. Wright Mills and the Theorists of Power
Abstract. This chapter reviews C. Wright Mills's analysis of power and the elites of his era in his three major texts of the 1940s and 1950s. It considers elements of his project that often attract less comment: Mills's search for possible ways of redistributing power and enhancing democracy: his attempt to forge an ethico-political stance in rapidly changing conditions.
D. Mill's Theory of Development– Explained!
J.S. Mill made a valuable contribution to the theory of economic development. He analyzed various factors of economic growth. He regarded economic development as a function of land, labour and capital. While land and labour are two original factors of production and capital is stock previously accumulated of the products of former labour. The wealth of a …
SAG Mill Grinding Circuit Design
The design of large mills has become increasingly more complicated as the size has increased and there is little doubt that without sophisticated design procedures such as the use of the Finite Element method the required factors of safety would make large mills prohibitively expensive. In the past the design of small mills, up t…
7.1.8: Mill's Utilitarian Proof
— John Stuart Mill (1806–1873) was concerned by many of the problems facing the utilitarian theory put forward by Bentham, but as a hedonist he did not wish to see the theory rejected.Mill sought to refine and improve the Benthamite utilitarian theory in order to create a successful version of Hedonistic Utilitarianism.
60 Years of Yang–Mills Gauge Field Theories
— The phrase "Yang–Mills" can be used (1) to refer to the specific theory proposed by Yang and Mills in 1954; or (2) as shorthand for any non-Abelian gauge theory. The 1954 version, physically speaking, had a famous show-stopping defect in the form of what might be called the "Pauli snag," or the requirement that, in the Lagrangian for ...
Mill, John Stuart, as Economic Theorist | SpringerLink
— J.S. Mill insisted on the Ricardian character of his economic theory: 'I doubt if there will be a single opinion (on pure political economy) in the book [Principles of Political Economy (1848)] which may not be exhibited as a corollary from his [Ricardo's] doctrines' (letter of 22 Feb. 1848; CW, XIII, p. 731).He did not ignore the criticisms of the preceding …
An Introduction to John Stuart Mill's
— Mill opens On Liberty by explaining the nature of liberty versus authority. Traditionally, liberty was defined as "the protection against the tyranny of political rulers" (Mill 2015, p. 5) To achieve liberty, limits on state authority ought to be imposed, which would eventually lead to those in power becoming more akin to tenants than perpetual …
Scalar-Scaffolded Gluons and the Combinatorial Origins of Yang-Mills Theory
— We present a new formulation for Yang-Mills scattering amplitudes in any number of dimensions and at any loop order, based on the same combinatorial and binary-geometric ideas in kinematic space recently used to give an all-order description of Tr $ϕ^3$ theory. We propose that in a precise sense the amplitudes for a suitably "stringy" form of …
A brief notes on Utilitarianism: A study on Bentham and J.S.Mill …
Those pleasures which go with the exercise of intellectual capacities are higher and better than sensuous pleasures. Mill made a difference between higher quality of pleasure and lower quality of pleasure. He preferred more noble pleasure over less noble pleasure. The main differences between Bentham theory and Mill theory are:
Sand Mill: Enhancing the Efficiency of Grinding & Dispersion

Moreover, sand mill machines can handle a wide range of pigments, including organic, inorganic, and metallic particles, making them indispensable within the paint and …
Classical Yang-Mills theory
Yang-Mills theory plays a central role in explaining fun-damental interactions, because both the strong and weak interactions are described by Yang-Mills theories.1,2 Stu-dents are usually introduced to Yang-Mills theory in the context of quantum field theory and never encounter Yang-Mills theory in its classical form. In contrast, students do
Yang–Mills theories
36 Yang–Mills theories discuss the gauge invariance of L B. We can now build a scalar Lagrange function for the B µ fields, L B =− 1 4 F µνF µν =− 1 4 F i F i,µν. (4.18) A theory with L B alone is called a pure Yang–Mills theory. For Lagrangians invariant under symmetries, we can also define currents of the
Nonrelativistic open string and Yang-Mills theory
— The classical and quantum worldsheet theory describing nonrelativistic open string theory in an arbitrary nonrelativistic open and closed string background is constructed. We show that the low energy dynamics of open strings ending on n coincident D-branes in flat spacetime is described by a Galilean invariant U(n) Yang-Mills theory. …
J.S. Mill: Education, Freedom, and Dependence | SpringerLink
Mill's views have had a tremendous and lasting influence, not just on liberal theory in general but also specifically on the topic of education (Collini, 1977).Though he is known more as a philosopher of freedom, today many of the distinctions he proposes, elaborates, and defends in the realm of education are so familiar they seem obvious or even intuitive.
Demystifying Sand Mills: Design, Types, And Working …

5 An introduction to Yang-Mills theory
G, and construct the corresponding Yang-Mills theory. As an example, I'll explain how Maxwell's equations can be regarded as a Yang-Mills theory with gauge group U(1). I won't explain the U(1)×SU(2)×SU(3) Yang-Mills theory in any detail, but in principle it is easy to construct using the recipe I will explain.
Introduction to Yang-Mills theories
— Yang-Mills theories are a class of classical field theory generalizing Maxwell’s equations. When quantized, Yang-Mills theories form the basis for all successful modern quantum field theories, including the standard model of particle physics, and grand unified theories (GUTs) that attempt to go beyond the standard model.

Mill, John Stuart: On Justice
— Mill begins the final chapter of Utilitarianism by looking for qualities which all concrete judgments of injustice share. It is commonly thought to be unjust, Mill says: to violate a person's legal rights, to violate a person's moral rights, to fail to give someone what they deserve, to disappoint expectations we have voluntarily given someone, to be …
