The equation of motion of the classic anharmonic oscillator is shown to have an exact solution in terms of elliptic functions both in the absence and in the presence of a sufficient weak external force. An external force depending on time as an elliptic function gives rise to resonance as in...

The left face of the rod moves a distancevtwhile the pressure wave travels a distanceutwith . The strain at the left face is (A1a)* From Hooke’s law, the pressure at the left face is (A1b)* (b) The velocityvis related to the displacementas in a simple harmonic motion (or a ...
The image attached in the beginning of this article shows the form our solution takes for the first few states of the simple harmonic oscillator. Note that you can multiply Ψ with complex conjugate Ψ*to obtain an expression for the probability of finding the oscillator at a point x. While...
A uniform mixture of substances in solid form. Solid solutions often consist of two or more types of atoms or molecules that share a crystal lattice, as in certain metal alloys. Much of the steel used in construction, for example, is actually a solid solution of iron and carbon. The carbo...
If the dimension n of the space is less than or equal to three, we can obtain some information about any solution u of (1.25) or (1.50) by reiterating the following simple procedure: the information we have on u gives us some regularity property of the nonlinear term ∑i =1nuiDiu...
