In physics,symmetryrefers to how particles behave when space, time, or quantum numbers are reversed. We’re used to seeing simple types of symmetry in everyday life. For example, a human face is very nearly symmetrical when reflected left to right. But a face is completely asymmetric when r...
What is a model??, which the present chapter sets out to answer. The genealogy of scientific models can be traced back to the use of mechanical analogies in 19th-century physics, and the first part of this chapter reviews some of the historical debates between, amongst others, Pierre Duhem...
mathematical structure. Rather, the mathematical model is for a specific object to a specific target, according to the unique inherent laws, make some simplifying assumptions necessary, using appropriate mathematical tools, a mathematical structure is obtained. The mathematical structure can be ...
(What is a function?) A function refers to a specific type of mathematical relationship that maps one set of inputs, known as the domain, to a corresponding set of outputs, known as the range. In simpler terms, a function takes an input va...
In this paper we introduce and study a new model for three–dimensional turbulence, the Leray–α model. This model is inspired by the Lagrangian averaged ... A Cheskidov,DD Holm,E Olson,... - 《Proceedings of the Royal Society A Mathematical Physical & Engineering Sciences》 被引量: 319...
It is now tempting to try to set up an approximately scale-invariant blowup solution. It seems that the first step in this is to construct a “soliton” type localized steady state solution, that is a solution , to the equation that decays in the variable; one can then hope to do a...

This is an attempt to describe the subject and the methodology of string theory as we understand them today, i.e., the entire set of problems which attract attention of theorists working in the field. The string model of Grand Unificatio... Morozov,A Yu - 《Soviet Physics Uspekhi》 被引...
Applied math is the bridge between mathematical theory and practical application. It involves taking established mathematical concepts and applying them to solve tangible problems in fields like engineering, physics, healthcare, and even finance. The goal is not just to explore mathematical concepts for...
