F33OT2 Symmetry and Action and Principles in Physics Contents
... The idea of the least-action principle, which you studied in F33OT1 in the context of Classical Mechanics, originates with Fermat in the 1660s. Fermat’s principle states that the path followed by a ray of light between two points is the one that takes the least time. This variational principle allow ...

Practice Problems
... Ex. 15 On your first five tests of the marking period, you earn grades of 95, 90, 80, 88, and 85. What grade would you need to earn on your last test so that you have an average of 88. Since you will have taken six tests and the average of the six tests is an 88, multiply 6 88. This will give you ...

... The finite difference algorithm results in a set of N equations. This is written as AE = B A is an N x N matrix (of complex numbers) that depends on the properties of the solution domain i.e. ( y, z ) and the grid spacing. The vector B includes information derived from the boundary conditions. ...

Partial differential equation

In mathematics, a partial differential equation (PDE) is a differential equation that contains unknown multivariable functions and their partial derivatives. (A special case are ordinary differential equations (ODEs), which deal with functions of a single variable and their derivatives.) PDEs are used to formulate problems involving functions of several variables, and are either solved by hand, or used to create a relevant computer model.PDEs can be used to describe a wide variety of phenomena such as sound, heat, electrostatics, electrodynamics, fluid flow, elasticity, or quantum mechanics. These seemingly distinct physical phenomena can be formalised similarly in terms of PDEs. Just as ordinary differential equations often model one-dimensional dynamical systems, partial differential equations often model multidimensional systems. PDEs find their generalisation in stochastic partial differential equations.
