A Stationary Phase Method for a Class of Nonlinear Equations - Yen Do
Yen Do Georgia Institute of Technology October 26, 2010 In this talk I will describe a real-variable method to extract long-time asymptotics for solutions of many nonlinear equations (including the Schrodinger and mKdV equations). The method has many resemblances to the classical stationa

Javascript games programming using Phaser in Dreamweaver lesson 7 - Firing bullets
In this lesson will manage to shoot the bullets in the same direction / angle as the space ship (player) object. We also control the rate at which they are shot so you can't shoot too many bullets at once.

Convolution in the time domain
Now that you understand the Fourier transform, it's time to start learning about time-frequency analyses. Convolution is one of the best ways to extract time-frequency dynamics from a time series. Convolution can be conceptualized and implemented in the time domain or in the frequency doma

Spacetime Diagrams: An Easy Way to Visualize Special Relativity (Physics by Parth G)
If you've seen a distance-time graph before, you'll pick up spacetime diagrams very quickly... and understand their true power in visualizing special relativity! A spacetime diagram is any diagram that shows the behavior of an object through space and time. However, the term most commonly

Phase space representation of billiards interpolating between a circle and a hexagon
