Mechanics to Manifolds I. An Introduction to Mechanics
This seminar is the first in a series of three which aim to explain some of the connections between Mechanics and Geometry. This first is very much focused on the Physics end. The aim of this talk is to be an introduction to Mechanics. There are a few theories of Mechanics, and it can sometimes be hard to separate them in the literature and applications. There are three main principles behind t...
متن کاملAn introduction to the mechanics of DNA.
This article gives an overview of recent research on the mechanical properties and spatial deformations of the DNA molecule. Globally the molecule behaves like a uniform elastic rod, and its twisting and writhing govern its compaction and packaging within a cell. Meanwhile high mechanical stresses can induce structural transitions of DNA giving, for example, a phase diagram in the space of the ...
متن کاملLie Groups and Mechanics, an Introduction
The aim of this paper is to present aspects of the use of Lie groups in mechanics. We start with the motion of the rigid body for which the main concepts are extracted. In a second part, we extend the theory for an arbitrary Lie group and in a third section we apply these methods for the diffeomorphism group of the circle with two particular examples: the Burger equation and the Camassa-Holm eq...
متن کاملIndistinguishable particles in quantum mechanics: an introduction
In this article, we discuss the identity and indistinguishability of quantum systems and the consequent need to introduce an extra postulate in Quantum Mechanics to correctly describe situations involving indistinguishable particles. This is, for electrons, the Pauli Exclusion Principle, or in general, the Symmetrization Postulate. Then, we introduce fermions and bosons and the distributions re...
